The high temperature furnace lining maintenance and maintenance

The high temperature furnace lining maintenance and maintenance

Lining maintenance (1) when the longitudinal cracking furnace wall, should be taken to slow heating way, make the melting of the reentry after crack bridging. (2) when the transverse cracking furnace wall, according to the actual situation in the transverse crack in fill in the fine powder, refractory material, then charging melting. (3) when the hearth erosion, available lining material for repair, and covered with iron plate after repair, add metal melt furnace charge low power full power to melt again after a period of time. Lining maintenance (4) under the cold furnace condition commonly, the furnace should use natural cooling, cooling or water cooling system does not allow water to cool. (5) melting at the end of the net liquid iron, in order to prevent the crack of the furnace wall, should be added for thermal insulation asbestos board on the front. (6) if it was stopped for a long time, the next time when blow-in melt slowly heat up, the lining of the small cracks close on its own.
