What is the effect of excessive aggregate particle on intermediate frequency furnace lining material? It will affect the uniformity of the lining material. If the lining is thin, a piece of aniseed may make the lining transparent and affect the strength of the lining.

What aspects affect IF furnace lining? There are five main aspects:

1, the loading criteria of the intermediate frequency furnace: First of all, we must determine the reasonable loading amount of the converter, 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 oxygen jet, and the depth of the molten pool must exceed the oxygen flow to the molten pool. Large penetration depth.

2. Oxygen supply criteria of intermediate frequency furnace: To determine scientific and reasonable oxygen supply criteria, the speed of impurity removal, melting pool heating and slag formation has an impact on the converter smelting and the service life of the lining.

3, the temperature criteria of the intermediate frequency furnace: under the premise of steel pouring content, the lower the temperature control of the steelmaking process and the end temperature, the more favorable the life of the furnace lining.

4, the furnace volume ratio of medium frequency furnace: the furnace volume ratio is too large will increase the cost of steelmaking, and the furnace volume ratio is too small will show splashing, 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 the intermediate frequency furnace equipment steelmaking, the quality of the original data used has a great impact on extending the life of the lining.

The above are the reasons that affect the lining of the intermediate frequency furnace equipment. I hope it will be helpful when you use the intermediate frequency furnace equipment in the future.
