Slide Gate Plate Refractories

The sliding nozzle is a control device for molten steel during the casting process of the continuous casting machine. It can accurately adjust the water flow from the ladle to the continuous casting tundish to balance the inflow and outflow of molten steel, thereby making the continuous casting operation easier to control. It is an ideal steel An indispensable part of the smelting process. The slide gate plate refractories is one of the main components of the sliding nozzle system and is also a commonly used functional refractory material in the continuous casting process.

Sliding nozzles can be divided into two-layer and three-layer types according to the number of slide gate plate refractories. The two-layer slide gate plate refractories means that the upper slide gate plate does not move and the lower slide gate plate following the mechanism. The two-layer skateboard is mostly used on the ladle mechanism. The three-layer slide gate plate is that the upper and lower slide gate plate do not move, and the middle slide gate plate with the mechanism to control and adjust the flow of molten steel; the three-layer slide gate plate is mostly used on the tundish mechanism.

For different capacity furnaces and different steel grade, slide gate plate refractories with different materials and sizes are applied.

Function refractories for continuous casting steel is a kind of advanced refractories aimed for clean steel. With function refractories, molten steel flow is better controlled, and could be protected from Oxygen during casting.

Function refractories for steel continuous casting generally include refractories from steel Ladle to Tundish and Tundish to Copper Mould Tube.

Function refractories are generally combined nozzles without binding agent, so the dimension and surface of such refractories are strictly controlled to match each other tightly.

Raw material：Tabular alumina or fused white alumina, natural flake graphite, zirconia material etc.
