How to remedy the problem of cracks in the ramming material

The intermediate frequency furnace ramming material is the fuel used for the smelting of the intermediate frequency furnace. It is a necessary equipment in the smelting industry. When the ramming material is used, cracks will appear. How to remedy it?

A) Improve the blasting method and select core-pulling tires to prevent transverse cracks formed when the tires are pulled out;

B) Improve the oven process and slowly heat up; 3) After opening a furnace, adopt a perfect method of heat preservation and slow cooling. Forging, casting, steel rolling, steel making, welding, heat treatment

C) Add a good sliding mica pad between the induction coil and the furnace lining to reduce the resistance of the induction coil when the furnace lining expands and contracts.

D) Adjust the particle size gradation ratio (increase the ratio of coarse particles)

The problem of cracks has been solved. How to prevent and improve the service life of the intermediate frequency furnace lining in the future? Please look down:

E. If the furnace capacity ratio of the intermediate frequency furnace is too large, it will increase the cost, and if it is too small, it will easily cause splashing and reduce the service life of the intermediate frequency furnace lining, so the furnace capacity ratio at the design should be maintained.

F. The loading amount of the converter should be reasonable. In addition to the appropriate furnace volume ratio, the appropriate depth of the molten pool should also be ensured (must exceed the penetration depth of the oxygen flow to the molten pool).

G, the intermediate frequency furnace charge manufacturer Alltong Kiln Industry recommends confirming scientific and reasonable oxygen supply criteria, ensuring the speed of impurity removal, slagging speed, removal of gas and inclusions in steel, and reasonable control of final carbon and temperature.

H, under the premise of good molten steel casting effect, the lower the temperature control and final temperature in the steelmaking process, the better.

I. The service life of the intermediate frequency furnace lining is affected by the quality of the raw materials used in converter steelmaking, such as molten iron, scrap steel, slag-forming materials, intermediate frequency furnace charges, slag conditioners and fluxes, etc.

The above is the introduction of how to remedy the cracks in the ramming material
