Integral pouring of refractory material from the belly to the throat of the furnace

It is applied to the middle and upper part of the furnace body, where the temperature is relatively low (generally 400~800 ℃), and there is no slag formation and slag corrosion hazard. The refractory lining of this part is mainly damaged by the impact of furnace charge, the abrasion or thermal shock of rising furnace dust (up to 50 ℃/min), the invasion of alkali, zinc and the like, and the deposition of carbon.

Use parts: hot air main pipe, stove top hot air main pipe, surrounding pipe, etc.

It is applied to the lower part of the furnace belly and furnace waist, where the temperature is high (the furnace belly can reach up to 1600 ℃), and a large amount of softening and molten slag iron is formed. The refractory lining is seriously eroded by thermal radiation and slag, and the hot furnace gas containing dust scoured the lining seriously, causing friction with the material and melt.
