Slide Gate Refractory

slide gate refractory is a high temperature burning skateboard, skateboard using high-quality corundum, alumina powder, bauxite, graphite and other raw materials pressed into. With high strength, high erosion resistance, high thermal shock resistance and other characteristics, can be widely used in large and medium-sized ladle, continuous casting tundish and so on. The high temperature sintering plate is divided into aluminum carbon, aluminum zirconium carbon, magnesium spinel, which can meet the needs of different steel grades.

The opening of sliding water orifice in ladle is used to control the size of molten steel flow and the height of liquid surface in tundish. The slide gate refractory is composed of an upper nozzle, an upper slide plate, a lower nozzle and a lower slide plate. In the operation process, the movement of the lower slide can be used to adjust the degree of overlap of the upper betting hole and then control the size of the flow, and there are two ways to adjust it, namely, hydraulic and manual.

Sliding nozzle action:

Because the sliding nozzle has to withstand the erosion of high temperature steel slag, the static pressure of steel and the role of rapid cooling and rapid heating, the refractory material is required to be resistant to high temperature, erosion, rapid cooling and rapid heating and good slag resistance, and has enough high temperature strength.

Advantages of ladle slide:

Ladle slide plate has the advantages of high strength, good erosion resistance, good thermal shock resistance, good stability, etc., mainly used in large and medium-sized ladle.

slide gate refractory features:

1, sliding surface flatness ≤0.05mm;

2, high mechanical strength;

3, high resistance to molten steel, slag pollution;

4, excellent oxidation resistance;

5, good thermal shock stability.
