Preparation of high-temperature-resistant and wear-resistant furnace lining material for 25-kilogram medium-frequency vacuum induction furnace and furnace lining building method
The invention discloses a preparation method of a high-temperature-resistant and wear-resistant furnace lining material of a 25-kilogram medium-frequency vacuum induction furnace, which comprises the following steps: mixing 8-20 parts by weight of magnesia particles with the particle size of 1-3mm and 6-15 parts by weight of fused alumina-magnesia spinel material with the particle size of 5-8mm, then adding 12-30 parts by weight of magnesia particles with the particle size of 0-1mm and 8-18 parts by weight of silicon carbide micro powder with the particle size of 200 meshes, and mixing to obtain a mixture; and adding water which accounts for 2-4% of the total weight of the mixed material, uniformly mixing, adding additive boric acid powder which accounts for 1.8-3.2% of the total weight of the mixed material, and stirring for a certain time to obtain the furnace lining material. The invention further discloses a method for building a furnace lining by using the furnace lining material. The process is simple, the high-temperature-resistant and wear-resistant furnace lining is obtained, the service life of the induction furnace lining is prolonged, and the adopted furnace lining mixture is non-toxic, harmless, environment-friendly and pollution-free.
本发明公开了一种25公斤中频真空感应炉耐高温、耐磨损炉衬材料的制备方法，将8～20重量份的粒度为1～3mm的镁砂颗粒和6～15重量份的粒度为5～8mm的电熔铝镁尖晶石料混合，再加入12～30重量份的粒度为0～1mm的镁砂颗粒和8～18重量份的粒度为200目碳化硅微粉混合为混合料，加入水，水的重量占混合后料总重量的2～4％，混合均匀后，再加入添加剂硼酸粉，添加剂硼酸粉的重量占混合水后料总重量的1.8～3.2％，搅拌一定时间后即制得炉衬材料。还公布了利用该炉衬材料筑炉衬的方法。本发明工艺简单，得到耐高温、耐磨损性好的炉衬，延长感应炉炉衬使用寿命，采用的炉衬混合料无毒无害，环保无污染。
