Brief introduction of furnace lining baking process

Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to understand the baking process of furnace lining:

1. Feeding: After the furnace lining is knotted, iron should be added for baking. It is required to add bread iron. Fill the furnace. Never add oily iron pins, iron beans, and mechanical iron. Because the furnace lining is not sintered. Oily When the material is heated at high temperature, a large amount of smoke and ammonia gas will be emitted. Through high pressure, a large amount of smoke and ammonia will be compressed into the furnace lining material, and then discharged to the outside of the furnace through the furnace lining material. After a long time, a large amount of flue gas residue will remain in the furnace lining material. Make the furnace lining black. The binder in the furnace lining loses its bonding effect, and the furnace lining is loose. The phenomenon of wearing through the furnace occurs. If there is oily material in the factory, it can be used after the furnace lining is completely sintered. (Use after 10 furnaces. ).

2. Starter panel: start from the current of 0.2 and keep warm for 20 minutes. 0.3 keep warm for 20 minutes. 0.4 keep warm for 20 minutes. 0.5 keep warm for 20 minutes. 0.6 keep warm for 40 minutes. —1650 degrees. Keep warm for 60 minutes. Baking is over.

3. Precautions for starting the cold furnace: start the cold furnace. Start from 0.2 for 10 minutes. 0.3 wait for 10 minutes. 0.4 wait for 5 minutes. 0.5 wait for 5 minutes.

4. Precautions for the shutdown of the hot furnace: when the hot furnace is shut down, the furnace temperature should be raised in the next furnace, and the glaze around the furnace mouth should be cleaned. The molten iron in the furnace should be poured out. Observe the condition of the furnace wall. It means that the furnace lining has become thinner. Pay attention to this part when starting the furnace next time. Cover the furnace mouth with an iron plate so that the furnace lining shrinks slowly.
