How to remedy cracks in ramming material

Intermediate frequency furnaceramming materialIt is the fuel used for intermediate frequency furnace smelting. It is a must-use equipment in the smelting industry. When using ramming material, cracks will appear. How to remedy it?

A) Improve the blasting method and use the core-pulling tire tool to avoid transverse cracks caused by pulling out the tire tool;

B) Improve the oven process and slowly heat up; 3) After opening a furnace, take perfect measures 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 avoid and improve the service life of the intermediate frequency furnace lining in the future? Please read below:

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 time should be maintained.

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

G. The intermediate frequency charge manufacturer Alltong Kiln Industry recommends determining a scientific and reasonable oxygen supply system to ensure the speed of impurity removal, slagging speed, removal of gas and inclusions in steel, and reasonable control of carbon and temperature at the end point.

H, under the premise of good molten steel casting effect, the lower the temperature control and end point 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
