Introduction to the solution to cracks in the ramming material of the intermediate frequency furnace

In the smelting industry, the intermediate frequency furnace is a must-use equipment, and the ramming material is the fuel used for the smelting of the intermediate frequency furnace. However, when many people use the intermediate frequency furnace, cracks will appear. How to solve the cracks? What? Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to learn more about:

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) The ramming material manufacturer adds a mica pad with good sliding properties 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)

In daily life, how to avoid cracks and provide the service life of the intermediate frequency furnace? Today, the professional ramming material manufacturers of Luoyang Quantong Kiln Industry Co., Ltd. teach you a few tricks:

A. 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. Therefore, the furnace capacity ratio at the time of design should be maintained.

B. 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).

C. The intermediate frequency furnace charge manufacturer Alltong Kiln Industry recommends to determine a scientific and reasonable oxygen supply system, ensure the speed of impurity removal, slag formation, remove gas and inclusions in the steel, and reasonably control the carbon and temperature at the end point.

D. Under the premise that the molten steel casting effect is good, the lower the temperature control and the end temperature of the steelmaking process, the better.

E. 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.
