Zero baking castable is a new type of refractory material that is free of maintenance and baking.The advantages of this material can be summed up as follows.1after the construction for the zero baking castable is finished, the nozzle can be started immediately to ignite for increasing to the operating temperature.During increasing temperature ang application, the construction object poured by zero baking castable is free of burst, crack, overburning, and chip off-falling, and can be used directly without maintenance and oven after construction .Capable of saving the oven cost , oven time and avoiding maintenance and oven after construction.2.The comparison of our zero baking castable with the low cement castable of the same aggregate and base material is shown as follows.As a type of coagulant, cement shall be added based on the addition ratio of 0.5~3%.The zero baking castable temperature at normal temperature and construction performance are higher than that of low cement castable.Because of the addition of less cement and the sharp decrease of low melting material introduced to the castable system, the zero bakingcastable performance at high temperature and operating temperature are superior to that of low cement castable.
Steel fiber refractory castble is a kind of hydraulic refractory castable with high-alumina clinker or brown corundum as aggregte and powder, mixed with binding agent and moderate amount of thermal-resistant and stainless steel fiber as well as admixture.
Steel fiber refractory castable is provided with the advantages of high strength, high temperature resistance, impact resistance, thermal shock resistance, good abrasion resistance and so on.
Steel fiber refractory castable products are classified into common stainless steel fiber refractory castable and nickel-plated stainless steel fiber reinforce refractory castable technology is provided with better high temperature resistance and rub resistance.
In the rotary klin calcining petroleum coke, the petroleum coke is calcined in a natural way, and the temperature is at about 1350.The lining material hall be of good thermal shock resistance, small changes in the lining line and excellent abrasion excellence. The castable produced by our company adopts dense brown corudum and mullite as the aggregate and fine powder, mixed with 97 sillicon carbide to increase the thermal shock resistance and abrasion resistance, and ensure small changes in the lining line. In the process of use, each castable plate is tightly bonded, without seams and castable peeling. And the petroleum coke is not sticky to the klin wall in the calcining process.
