What are the refractory materials used in the steel industry？

In the steel industry, refractories play a key role in protecting and maintaining the high temperature environment inside the kiln.Refractory materials are used for kiln masonry and maintenance, and the types of refractory materials used in each part are different.

Types of kilns used in the steel industry

Converter: The converter is one of the commonly used steelmaking kilns. It uses oxygen blowing to oxidize and remove impurities in pig iron to obtain qualified molten steel.

Electric Arc Furnace: An electric arc furnace is a device that uses the high temperature of an electric arc to melt and smelt scrap steel or pig iron. It is widely used in scrap steel recycling and steel production.

Induction Furnace: An induction furnace is a device that uses the principle of induction heating to melt and smelt metal materials. It is often used in small-scale and special steel production.

Blast Furnace: A blast furnace is one of the most common steelmaking kilns, a large-scale smelting equipment used to reduce iron ore into pig iron.

Refractories for the steel industry

Briques réfractaires: used for the inner wall masonry of high-temperature furnaces, such as blast furnaces, convertisseurs, fours électriques, etc..

Bétons réfractaires: used for pouring and repairing of various components inside the kiln, such as ladles, iron gates, furnace walls, etc..

Refractory fiber: used for high-temperature heat insulation, heat preservation, sealing, sound insulation, etc., such as furnace door insulation pads, pipe insulation materials, etc..

Refractory spraing mass: used for surface coating of various components inside the kiln, such as anti-corrosion coatings, wear-resistant coatings, etc..
