Product Introduction:
Converter Tapping-hole Filling Material is an important refractory material used in converter steelmaking. Its main function is to fill and seal the area near the steel outlet to prevent molten steel and slag from overflowing and protect the furnace lining from high temperature erosion and damage. Converter Tapping-hole Filling Material uses fused magnesia and sintered magnesia as the main raw materials, with synthetic additives added. It is divided into two categories: magnesia and magnesia carbon according to user needs.

Product advantages:
1. Our Converter Tapping-hole Filling Material has good high temperature resistance and is not easily affected by high temperature and thermal cycle in the furnace, ensuring the safety and long-term stable operation of the tapping hole area.
2. Our Converter Tapping-hole Filling Material is corrosion-resistant and effectively resists the erosion of slag, molten steel and other corrosive substances, reducing the wear and damage of the furnace lining and extending the service life of the furnace lining.
3. Our Converter Refractories have appropriate thermal expansion characteristics, which can match the thermal expansion of the furnace lining and molten steel, avoiding cracking or damage caused by inconsistent thermal expansion.
Functions of converter refractories:
1. converter refractories can be used to seal the tapping port of the converter during steelmaking to prevent molten steel and slag from overflowing from the outlet, and to maintain the safety and stability of the steelmaking process.
2. converter refractories can effectively protect the lining around the converter tapping port from damage caused by high temperature and slag erosion, prevent wear and damage to the lining, and extend the service life of the lining.
3. The selection and construction of converter refractories can affect the fluidity and discharge mode of the slag, help optimize the handling of the slag and the cleanliness of the molten steel.
4. Through the effective use of converter refractories, the loss of oxidation reaction in the furnace can be reduced, and the steelmaking efficiency and the stability of the composition of the molten steel can be improved.
5. The correct selection and use of converter refractories can reduce the safety risks of operators and ensure safe operation under high temperature and high pressure environments.
