Refractory Castable Preform
May 28, 2018

The application of refractory castables in the furnace industry is becoming more and more important. Because of the special structure of the furnace equipment, especially the aluminum smelting furnace, the size of the furnace is smaller than the steel metallurgical furnace and the structure is complex. The structure of the furnace gate, the fire mouth, the exhaust port, the feeding port, the inlet of the aluminum inlet, the discharge port and so on is complex, and the size of the furnace is complex and the size of the furnace is complex. Strict requirements. Its high temperature strength requires high wear resistance, erosion resistance and good overall structure. In addition to the bottom and side insulation materials, the furnace hearth, the furnace wall and the top of the furnace can be constructed by using the precast parts once in the new kiln (including overhaul).

Medium repair, which is damaged in furnace village and needs partial repair, can be replaced by precast parts, whether it is brick masonry or precast brickwork.

No matter the repair of a new furnace or kiln, the construction period is shortened by 50%. As the prefabricated parts are produced in the factory, and the water has been eliminated after drying, the structure is stable and the strength is high, so the time for baking is shortened. From construction or overhaul to production, the whole cycle is greatly shortened and the efficiency is greatly improved.

The prefabricated furnaces have good overall structure, and no cracks occur in the oven when the building process is not in place. The leakage occurs when the preform is used. Because between the preform and the preform, the seepage prevention measures are taken between the preform and the preform, which is not only anti leakage but also a expansion joint, so the whole body and the sealing performance are good.

According to the requirements of different products or processes, different materials can be used. Different types of low cement and high strength preform can be used on the top of the furnace, and the preform of high strength castable and non stick aluminum castable can be used in the bottom of the furnace and the wall of the furnace.
