Introduction of remedies for cracks in ramming material

Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to knowramming materialRemedies for cracks:

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)

How to avoid and improve the service life of intermediate frequency furnace lining in the future?

1. If the furnace volume ratio of the intermediate frequency furnace is too large, the cost will be increased, and if it is too small, it is prone to splashing and reduce the service life of the intermediate frequency furnace lining, so the furnace volume ratio at the time of design should be maintained.

2. 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).

3. Quantong Kiln Industry recommends to determine a scientific and reasonable oxygen supply system to ensure the speed of impurity removal, slag formation, removal of gas and inclusions in steel, and reasonable control of end-point carbon and temperature.

4. Under the premise of good molten steel casting effect, the lower the temperature control and end point temperature in the steelmaking process, the better.

5. 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.
