What are the aspects that affect the intermediate frequency furnace lining? Below, and Hubei lining materials sales company Xiaobian together to understand the next!

1. Loading criteria for intermediate frequency furnace

First, it is necessary to determine the reasonable loading amount of the converter and the suitable ratio of hot metal and scrap steel. However, in determining the loading capacity of the converter, in addition to considering the appropriate furnace volume ratio, the appropriate depth of the molten pool should also be considered, so as to protect the bottom of the tube from the impact of the oxygen jet, and the depth of the molten pool must exceed the penetration depth of the oxygen flow to the molten pool.

2, medium frequency furnace oxygen supply criteria:

In order to determine the scientific and reasonable oxygen supply criteria, the speed of impurity removal, melting pool heating and slag-making have an impact on the intensive smelting of the converter and the service life of the lining.

3, medium frequency furnace temperature criteria

Under the premise of the content of molten steel pouring, the lower the temperature control and the lower the end temperature of the steelmaking process, the more favorable the life of the furnace lining.

4, medium frequency furnace volume ratio

If the furnace volume ratio is too large, it will increase the cost of steelmaking, while if the furnace volume ratio is too small, it will show spatter, thereby reducing the service life of the furnace lining. So it is very important to design a reasonable furnace volume ratio of intermediate frequency furnace.

5, the quality of the original data

When intermediate frequency furnace equipment makes steel, the quality of the raw data used has a great influence on prolonging the life of the lining.
