The application of refractory castable prefabricated parts in the furnace kiln industry is becoming more and more valued, because the special structure of furnace equipment, especially aluminum furnaces, the furnace kiln is relatively small than steel metallurgical furnace kiln, and the structure is complicated. The structure of the fire outlet, the smoke exhaust port, the ingredient port, an aluminum inlet, and the water outlet is complicated, and the size requirements are strict. Its high temperature intensity requires high, at the same time, wear resistance, brushing, and good overall structure.
When the production of the pre -production of the castable materials is to design and process all the prefabricated molds according to the drawings, and then choose the appropriate raw material according to the actual needs to process the refractory pouring materials according to the process. Or pad the paper, then pour the watering into the processed prefabricated molds. After the various corners are uniform, then vibrate and mold. After the formation of the prefabricated parts, after the beginning of the first condensation and the final condensation, then the mold is processed. Then Make dry to 300 ° C to bake the crystalline water of the prefabricated piece, which not only ensures the strength of the prefabricated parts, but also facilitates transportation. It is more conducive to the convenience of construction.
In the new furnace kiln (including large repair), in addition to the bottom and side insulation materials, the bottom of the furnace, the furnace wall, and the top of the furnace can be made of prefabricated parts. In the furnace village damage and local repair, it is necessary to repair it. Whether it is originally brick or prefabricated, prefabricated parts can be used for local replacement repair.
Regardless of the repair of new furnaces or furnaces, its construction cycle is shortened by 50%. Since the prefabricated parts are produced in factory, and after drying, the water is eliminated. The baking time is shortened. From construction or repair to the entire cycle of production is greatly shortened, the efficiency is greatly improved.
The furnace kiln built by prefabricated parts has good overall structure and will not cause cracks when the bayonet is not in place. Measures are both anti -leakage and telescopic joints, so the overall and sealing performance is better.
According to the requirements of different products or processes, different materials can be used. The top of the furnace can be based on the size of the furnace. Different types of low cement high -intensity prefabricated parts can be used. The bottom of the furnace and the wall of the furnace can be poured with high -intensity pouring and non -sticky aluminum pouring.
