How to maintain high temperature tubular furnace lining?
How to maintain high temperature tubular furnace lining?
1. When longitudinal cracks appear on the furnace wall, a form that does not heat up quickly should be used to make the cracks heal before smelting.
2. When the transverse cracks are exposed on the furnace wall, the crushed refractory materials can be filled in the transverse cracks, and then the materials are melted.
3. When the furnace bottom is peeled off, the furnace lining material can be used for repairing. After repairing, it is covered with an iron plate. The metal furnace material is melted at full power after being melted at low power.
4. The protection and protection of the lining is usually carried out under the conditions of a cold furnace. The furnace should be considered suitable and cooled by natural cooling or water cooling systems, and the fountain does not allow cooling.
5. After the smelting is completed, take out the net molten iron. In order to avoid cracks in the furnace wall, asbestos boards should be added to the furnace mouth for heat preservation.
6. If the furnace is closed for a long time, it will be heated and quickly melted at the next furnace opening, so that the small cracks in the furnace lining will heal itself.
