【鼎晟】中性炉衬料 打捣料 浇注料 不定型耐火材料 中性打炉料
中频炉耐火材料主要包括中频炉炉衬料(也称中频炉打炉料、中频炉干振料、中频炉干打料、中频炉捣打料等)、中频炉修补料、线圈泥(也称线圈胶泥、线圈涂料、线圈浆料)、中频炉炉口料、运转包用浇注料等，该系列耐火材料主要用于无芯中频炉、有芯感应炉、熔液运转包中，用以熔化灰口铸铁、球墨铸铁及铸铁合金，熔化碳钢、合金钢、高锰钢、工具钢、耐热钢、不锈钢，熔化铝及其合金，熔化紫铜、黄铜、白铜及青铜等铜合金等。
一、炉料特点：
（1）、该炉料为中性材料，耐火度1790℃，最高使用温度1650℃；
（2）、应用范围：铸铁、铜铝合金、低合金钢、高锰钢。
二、筑炉工艺：
（1）、铺设好玻璃丝布和石棉布，接口采用搭接，并且屋与层之间接口应错开，以保证其平整性和整体性。
注：如果所用电炉有特殊要求，此方法仅供参考。
（2）、粘结剂建议使用硼酸，加八量占炉料重量的1.5-2%。一般在炉底与炉壁用1.5%，炉口处用1.8%，使用时过0.425mm筛。建议使用俄罗斯
产，纯度为工业纯级。（粘结剂也可使用水玻璃加入量夏7.5%，冬8.5%）。
（3）、采用湿法打结时，炉底部位的材料加水量占炉料重量的1%，炉壁和炉口处加水量与所用硼酸重量比例相同。在使用时加水量一般以用手
使劲捏成团，散开手后稍加振动即碎即可。
（4）、炉料与硼酸及水混合时必须混匀，避免分层，称量必须准确，以免造成粒度偏析使壁厚不匀和疏松。人工混料时，应先将炉料混匀摊平，将硼酸均匀筛在料上，再掺匀，然后将水均匀洒在料上，掺均匀待用；如果使用搅拌机混料，根据炉料的粒度，调整搅拌机铲刀的间隙，每次加炉料100kg，搅拌均匀，加入硼酸搅拌5mm，再加入搅拌10mm，从缝隙中漏出的料应重新回到搅拌机中，炉子不同部位所用的材料加入硼酸
和水的比例不同，应分别拌料。拌好的料应一次使用完，不能放太长的时间。如果特殊原因间隔时间太长应用润湿的麻袋盖好，打完一个炉衬，剩余的材料最好不要再混入炉料内使用，以免影响使用效果。
注意：
（1）、混料的场地应保持干净，严禁任何非炉料类物质混入炉料；
（2）、拌料均匀是保证炉衬致密的关健。
5、坩埚模一定要感应线圈保持最好的同心度，固定紧实，以免打结时位移，造成炉壁厚度不均匀。坩埚模表面应保持清洁，平整。如果打完炉
后起出，可在其表面涂刷薄层钠基润滑脂，以利脱模。
6、筑炉底时将炉料均匀分批加入感应器内摊平，平底锤捣实，每批散料厚度约40mm，捣实后将表面均匀划松约15mm，以便与下批材料紧密结合。打好后安装并固定坩埚模，筑炉壁时，每屋加料30-35mm，捣打紧实，每层捣打15mm以上，层与层之间应在打好后将表面均匀划松，以利结合，以免产生横向裂纹。
注意：
（1）、打炉时应有专人现场指挥，所有工具保证清洁。注意检查所有工具有无焊渣，或其它可能对炉壁造成影响的物质。打炉时请勿抽
烟，请不要在口袋内装易掉出的东西，因为所有杂物对炉衬都会产生损伤；
（2）、保证工作场地及炉膛内有工作灯照明，以便随时观察可能发生的情况；
（3）、量准确炉内的高度，以后每打一层，量一层，做好记录，并记录打结一层所用的时间；
（4）、炉底和炉壁的结合处最容易出现问题，此处一定注意打结紧实并结合严密；
（5）、中性炉料膨胀系数1500-1600℃时为1.0-1.1%，没有晶型转变，所以打结紧实并严密结合是保证整个炉衬寿命的关键；
（6）、人工打时，应注意换位，以避免力量不均匀导致致密度不均匀，不能局部过于用力；
（7）、炉料粒度混合均匀，加料时不要在太高处随便往里过倒，这样易产生偏析，应尽可能在最低处倒入，并将其先扒平再打结，坩埚模处一
定注意捣打紧实，此处在烧结后是工作部位，若打不好，易冲刷掉或渗漏钢水。
8）、不要碰破铺设的石棉布和玻璃丝布，掉入炉料内的石棉布或其它物质用小勺取出。
7、炉口处打好后，可在表面涂挂一层水玻璃。炉口处不要使用其它材料，因膨胀系数不同，高温膨胀，低温收缩易产生裂纹，以致渗漏钢水。
8、起模时，应注意合力的方向，严禁损伤炉壁。因为打好的炉壁尚未进行烧结，还没有足够的强度，打好后的炉子严禁倾斜或移动。
三、烧结机理：
烧结实际上是在低于熔点的温度下，固体颗粒的重排、气孔率下降、强度和硬度提高的致密化过程。在烧结过程中，使炉衬靠近钢（铁）水的一侧形成一定厚度的致密体，即形成所需的坩埚，以承受高温钢水的冲刷和抵抗熔渣渗透所引起的化学侵蚀，使炉衬保持较高的寿命。
1、烘炉时，炉壁一周均匀放置长条洁净钢料，因炉壁尚未烧结加料时应轻放以免碰损炉壁，炉口加可以透气的盖，以每小时升10kw的功率，烘
烤12小时，中途不可断电。尽量保证炉壁受热均匀。
敬请注意：
1）、仅建议用电烘炉，以使其均匀受热；
2）、如果有其它丰富的或先进的烘炉经验本公司不拒绝采用，但如果造成不良后果则与本公司无关；
2、烘好炉后，可以加入金属炉料，第一炉应保持金属炉料清洁无锈，并成份相同或相近，满负荷运行；使炉料尽快全部熔清，并在熔化温度（
1450-1500℃）保温0.5小时以上，即可完成烧结。然后进入后期熔炼工序。
四、小结
对于中频炉炉衬的寿命，除保证获得完整合理的三层炉衬外，还应注意平时的操作，筑炉是选用优质干净的筑炉材料，合理配比，精心打结，科学烘烤与烧结规范，严格操作工艺，即可延长炉子使用寿命。

英文说明：
Intermediate frequency furnace refractory materials mainly include intermediate frequency furnace lining materials (also known as the intermediate frequency furnace burden, intermediate frequency furnace dry vibrating material, intermediate frequency furnace dry ramming material, intermediate frequency furnace material, etc.), intermediate frequency furnace repairing, coil clay cement (also called coil, coil coatings, coil size), intermediate frequency furnace throat opening, synthetic castable, such as operation, this series is mainly used for refractory coreless medium frequency furnace, induction furnace, molten package, running to molten gray iron, ductile cast iron and cast iron alloy, molten carbon steel, alloy steel, high manganese steel, tool steel, heat-resistant steel, stainless steel, melted aluminum and its alloy, melting copper, brass, copper and bronze, copper alloy, etc.
Product introduction: neutral play burden
First, furnace charge characteristics:
(1), the burden to neutral materials, refractoriness 1790℃, the highest temperature is 1650℃;
(2), scope of application: cast iron, copper, aluminum alloy, low alloy steel, high manganese steel.
Second, the construction process:
(1), laid good glass cloth and asbestos cloth, interface USES the lap joint, and the interface between house and layer should be staggered, so as to ensure the smoothness and integrity.
Note: if you have any special requirements, electric furnace used this method for your reference.
(2), recommend the use of boric acid binder, plus eight volume accounts for 1.5 2% of furnace charge weight.With 1.5%, general in furnace bottom and furnace wall front place with 1.8%, when using a 0.425 mm sieve.Recommend the use of Russia
Purity, pure level for industry.(also can use the summer for the amount of sodium silicate binder 7.5%, 8.5%) winter.
(3), using wet knot, furnace bottom bit add water accounted for 1% of charge weight, furnace wall and front place with water and boric acid used in the same weight ratio.Water is added when using general with hand
Tried to knead dough, scattered hand after a little vibration that is broken.
(4), the furnace charge to be blending when mixed with boric acid and water, avoid layering, weighing must be accurate, so as not to cause the particle segregation that wall thickness and not loose.Artificial mixing, should first will burden blending lay flat
, then sieve boric acid evenly on the material, and then mixed evenly, then water sprinkle evenly on the material, mixing evenly to use;If you use a blender mixing, according to the burden of granularity, adjust the mixer cutter gap, each
Time and burden of 100 kg, stir, stir in boric acid 5 mm, stir and add 10 mm, leak from the crack of material should be back in a blender, materials used in the different parts of the stove to join boric acid
And the proportion of different water, should mix material, respectively.Mixed material should be used up, can't put too long time.If special reasons of wetting time interval is too long application bag cover, a lining
, the rest of the material had better not to use in mixed with burden, lest affect the use effect.
Note: (1), mix material field should be clean, it is strictly prohibited to any non burden material mixed with burden;
(2), uniform mixing materials is the key to guarantee the lining of dense.
5, crucible mold must maintain the best concentricity induction coil, fixed tight, in order to avoid the knot displacement, furnace wall thickness caused by uneven.Crucible mold surface should be clean and smooth.If after the furnace
Tie out, can besmear brushs a thin layer on the surface of sodium base grease, mold release.
6, build the furnace bottom at adding burden even partial sensors inside flat, flat hammer tamping, about 40 mm, each batch bulk material thickness after tamping surface evenly to draw about 15 mm, so closely integrated with the next batch of material
.Play after installed and fixed crucible mold, built a wall, each house feeding 30-35 mm, dao matter, each layer of ramming 15 mm above, should be in after good will between layer and layer surface uniform row pine, eli
, lest produce transverse crack.
Note: (1), the furnace should have personnel on-site command, all tools to ensure clean.Pay attention to check all the tools without welding slag, or other substances that may affect the furnace wall.Please do not smoke while playing the furnace
Smoke, please don't pack easily drop out in the pocket, because all the stuff on the lining will damage;
(2), ensure that work place and furnace with working lamp lighting, in order to observe the possibility of circumstance;
(3), the amount is accurate, the height of the furnace and after every layer and a layer, recorded, and records the knot a layer of the time;
(4), the junction of furnace bottom and furnace wall are most likely to appear problem, here must pay attention to knot, tight and tight;
(5), neutral charge 1500-1600℃expansion coefficient of 1.0 to 1.1%, no crystal structure change, so the knot, tight and tight combination is the key to ensure that the lining life;
(6), artificial, transposition, should be paid attention to in order to avoid uneven power results in uneven density, not local too hard;
(7), furnace charge particle size mixing, when feeding don't too high at random to fall, so prone to segregation, should combine as far as possible in the lowest place, and its first steak flat knot again, a crucible mold
Her mind dao matter, here in after sintering is the work place, if can't play well, easy to wash away or molten steel leakage.
8), don't touch of asbestos cloth and glass cloth, fall into the burden of asbestos cloth or other material with a small scoop out.
7, the oven after good, can be in surface coating a layer of sodium silicate.Front place do not use other materials, because of the different expansion coefficient, heat expansion, low temperature shrinkage cracks easily, so that molten steel leakage.
8, draw, should pay attention to the direction of the force, it is forbidden to damage the furnace wall.Because a good not yet sintering furnace wall, also did not have enough strength, play the stove after it is forbidden to tilt or move.
Sintering mechanism: sintering is actually under the temperature below the melting point of solid particle rearrangement and the decrease of the porosity, strength and hardness increase the densification process.In the process of sintering, make the lining
Nearly steel (iron) on one side of the water to form a certain thickness of the dense body, that is needed for the formation of crucible, to withstand high temperature of molten steel slag penetration resistance and scouring caused by chemical attack, keep the furnace lining is higher
In the life.
Week 1, oven, furnace wall even placed long clean steel materials, has not yet been sinter charging for furnace wall should be light so as not to touch the damage of the furnace wall, when the oven can be breathable cover, litres per hour 10 kw of power, drying
Bake for 12 hours, not power.Try to ensure uniform heating furnace wall.
Please note:
Only 1), electric oven, in order to make the uniform heat;
2), if there are other rich or advanced oven experience the company refused to adopt, but if adverse consequences have nothing to do with the company;
2, good baking furnace, can join the metal furnace charge, for the first furnace metal furnace charge shall be maintained clean without rust, and the same or similar ingredients, run at full capacity.Make the burden all rongqing as soon as possible, and the melting temperature (
1450-1500℃) heat preservation more than 0.5 hours, can complete sintering.Then late into the smelting process.
Third, summary
For intermediate frequency furnace lining life, in addition to assure you get complete three layers of lining, also should pay attention to the usual operation, is to build furnace with high quality clean furnace building materials, reasonable matching, elaborate knot, baking and sintering norms of science, strict operating process, can prolong the service life of the furnace.
Fourth, packing and storing method
Multilayer moistureproof paper and lining packing 25 kg/bag, stored in a dry place to prevent moisture absorption.Shelf life of no more than a year.
