What is the effect of excessive aggregate particles in the lining of the intermediate frequency furnace?

What will be the effect of too large aggregate particles in the lining of the intermediate frequency furnace? It will affect the uniformity of the lining. If the lining is thin, a large piece of material may make the lining transparent, which will affect the strength of the lining.

What aspects affect the lining of the intermediate frequency furnace? Mainly the following five aspects:

1. The charging principle of the intermediate frequency furnace: First of all, determine the reasonable charging volume of the converter, the appropriate molten iron and scrap ratio. However, when determining the charging volume of the converter, in addition to considering the appropriate furnace capacity ratio, you should also consider the appropriate guarantee. The depth of the molten pool, which is done to protect the bottom of the tube furnace from the impact of the oxygen jet, and the depth of the molten pool must exceed the oxygen flow to the molten pool. Large penetration depth.

2. Oxygen supply principle of intermediate frequency furnace: It is necessary to affirm the scientific and reasonable oxygen supply principle to ensure the removal of impurities, the temperature of the molten pool and the speed of slag making, which have an impact on the enhanced smelting of the converter and the service life of the furnace lining.

3. The temperature principle of the intermediate frequency furnace: under the premise that the molten steel is satisfied with the casting, the lower the temperature of the steelmaking process and the lower the end temperature, the more beneficial the service life of the furnace lining.

4. The furnace volume ratio of the intermediate frequency furnace: if the furnace volume ratio is too large, the cost of steelmaking will increase, while if the furnace volume ratio is too small, splashing will occur, thereby reducing the service life of the furnace lining. Therefore, a reasonable intermediate frequency furnace should be designed. The furnace capacity ratio is very important.

5. Quality of raw materials: When making steel with intermediate frequency furnace equipment, the quality of raw materials used has a great influence on prolonging the life of the furnace lining.

The above are the reasons that affect the furnace lining of the intermediate frequency furnace equipment. I hope it will help you when you use the intermediate frequency furnace equipment in the future. If you want to know more about the furnace lining material, you can pay more attention to our company.
