Description of Refractory
This product is suitable for the production of gray iron, nodular iron, malleable (cast) iron, and low carbon steel, etc. It is a new high quality casting material in the casting industry. This product is a quartz coreless induction furnace refractory with acid material. And it is characterized by high purity of raw materials, reasonable grading and high stacking density. ZT Series lining materials have been widely recognized by our customers, more than 95% of whom find it satisfactory.
Features of Refractory
> It is made of high-purity large crystal quartz and new materials, which assures better insulation and lower thermal conductivity than the acid material configured with ordinary quartz, making the production more energy-saving and safer.
> With high purity material, strict control of impurities and perfect crystal structure of components, the lining material is enabled with higher fire resistance, good high temperature performance and acid slag corrosion resistance than ordinary quartz acid material.
> The furnace lining is uniform and densified, with small change of thermal volume, and uneasy to crack in layers or slag. And it is featured with strong ability to avoid crack, heat shock and erosion.
> The lining is stable and against deterioration after long-term operation.
> Construction method: dry ramming recommended.
Furnace Building, Heating and Sintering Process
Correct furnace building, heating, sintering process, and appropriate operation and maintenance are the keys to ensure the normal operation of furnace lining and to improve the furnace life.
Packaging Standards and Storage Methods
> Imported new kraft paper with moisture-proof
> Leaking proof package, 25kg / bag, can be packaged as per the user's requirements.
> Stored in dry place away from moisture.One year shelf life.
