What is the baking process of furnace lining

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

1. Feeding: After the furnace lining is knotted, iron will 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 lot of smoke and ammonia gas will be emitted. After high pressure, a lot 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 lot of flue gas residues will remain in the furnace lining material. The lining material is blackened. The binder in the lining material loses its bonding effect, and the lining becomes loose. The phenomenon of wearing through the furnace occurs. If there is oily material in the factory, it can be used after the lining material is completely sintered. (10 furnaces will be used in the future. ).

2. Starter panel: start from current 0.2, 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 completed.

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: the hot furnace is stopped. 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 furnace wall. The blackened part of the furnace body Explain 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. Make the furnace lining gradually shorten.
