What are the characteristics of non-carbon steel refractory materials

The technology of non-carbon steel package is mainly based on the interaction between slag - liquid steel - refractory material as a starting point, by controlling the composition of refractory material at high temperature, mutual penetration and mutual reaction with the minerals in the steel slag to generate a reaction layer with excellent performance, so as to firmly combine the used residual layer with the new layer.

1. Performance characteristics

1) Lining material. Non-carbon steel lining material is used to tie the bottom of the bag. The material used in the bottom of the bag can improve the life of the bottom of the bag and protect the breathable brick and seat brick. On the other hand, each minor repair of the material only needs to maintain and spray the impact area of the bottom and the erosion part of the carbon-free precast of the cladding. The effect is good.

2) lining spray feed. The spray supplement is an amorphous material, which comes from the same matrix system as the body preform and is prepared with highly synthetic material as the raw material. This spray supplement is composed by controlling the phase of high temperature substances, and reacts with the minerals of the metamorphic layer of the cladding preform at high temperature to generate a reaction layer with excellent properties, so as to bond the used metamorphic layer with the new spray supplement firmly.

3) Spraying process. After removing the remaining cold steel on the cladding wall, the spray repair machine is used to repair the areas seriously eroded by molten steel slag such as the steel facing surface and the slag line.

2. Use characteristics

1) Good performance. Spray and prefabricated slag layer is well combined, corrosion resistance and erosion resistance, after use, the wall is smooth and uniform, no crack spalling and other phenomena, slag phase and carbon-free prefabricated parts and spray and prefabricated material into one.

2) High service life. After use, the life of conventional non-carbon brick masonry ladle is increased by 30%-50%.

3) Good economic benefits. Carbon-free new technology ladle instead of magnesium carbon brick reduces the consumption of tons of steel resistant materials, reduces gas emissions and reduces energy consumption, is an environmentally friendly and energy-saving product.
