Refractory material for torpedo car liner

Refractories for torpedo car liner, countries basically the same. In the complex structure and damageable parts, such as receiving iron mouth and nozzle etc., some with unshaped refractory materials instead of special-shaped brick, the use of more successful. America by phosphoric acid high alumina castable produced by iron mouth and spout lining, simple construction, no residue, long life. Japan, Germany, Britain and other countries of the torpedo car receiving iron mouth parts damaged,

the fire-resistant paint spray repair, also obtained better technical and economic results.

Foreign hot metal pretreatment with refractory materials generally use Al2O3 - SiO2 castables, the content of Al2O3 is 70% to 80%. If add SiC, C or Cr2O in the spray material, can effectively improve the anti slag corrosion, adding steel fiber will improve the spalling resistance. Recently developed zircon castable, the effect is relatively good. When the torpedo car using Al2O3 - SiC refractory brick, masonry should also be the same material of Al2O3 - SiC - C fire clay.

With the increasingly wide application of torpedo car, also put forward higher requirements on the selection of refractory lining, in addition to excellent, also should consider reasonable use question, in order to further extend the torpedo car life, and reduce the cost of.
