Mixer Furnace, Casting House and Metallurgical material
refractory castable
Adopt to all kind of furnaces product: Zero baking castable. 1.definition: Zero baking castable is a type of castable that after the construction of castable, you can heat up temperature directly to common usage temperature with not any time and condition, even not solidfication. Meanwhile there is not appear any undesirable phenomenon, and do not affect quality. 2.Three natural enemies of refractory castable: the castable has three natural enemies naturally. Firstly,it is
Catsable for Slag line
The castable for slag line has the properties other than stable high temperature performance, it mainly sustain the high temperature erosion of slag, and sustain the thermal shock, washing-out, abrasion over and over again from molten iron and slag. Of course, reasonable design is very important too.

Castable for Taphole
Because there are many limitation for pouring castable at the tap hole, the castable for tap hole not only have the all features of castable for slag line,but also must have stronger, higher wear resistance.Owning of batch tapping, the castable must have better thermal shock resistance.

Castable for Furnace bottom, refractory material
The castable can supply the largest load bearing in the mixer furnace, it must not only have the stable high temperature performance, but also can work under pressure of hundreds tons of liquid iron. In local part, the castable must resist to the washing-out and abrasion during pouring melted iron, and the the site is the most difficult repair part, the construction at bottom is highly important.

Castable for Furnace top, refractory castable
The castable is a kind of castable that does not touch molten iron, on the surface, the castable need not high requirement, but it is not. It have to can work at high temperature condition, bear its own gravity downward, resist to the slag erosion and the thermal shock when pouring and releasing iron. Therefore, the technology can not be unidirectional. Physicochemical index Chemical composition (%) Volume density (g/cm3) Flexing stength ( MPa) Linear change rate (%) Al2O3
