Q80 sliding plate for ladle

High Temperature Burnt Slide Plate
Fine property burnt slide plate adopts tabular corundum, carbonaceous and zirconia as main raw materials, adding in high performance antioxidants, using phenolic resin as binding material, formed under high temperature and burned under high temperature.
High temp. burnt slide plates obtain the advantages of high mechanical strength, oxidation resistance, good erosion resistance, thermal shock resistance and good stability.
Widely used in large and medium size ladle, refining ladle, ladles for casting alloy steel.

Sliding plate for ladle is the key part in the slide gate systems. Function is to control the flow rate of molten steel.
The slide plate is exposed to high temperature molten steel repeatedly, especially the cast hole part, the erosion is serious,
this require the slide plates obtaining features of High strength, excellent corrosion resistance, anti-stripping, to ensure no steel leak during pouring process.
The features of LQ Slide gate plates:
1. Flatness of sliding surface ≤0.05mm
2. High mechanical strength
3. High resistance to contamination of molten steel and slag
4. Excellent oxidation resistance
5. Good thermal shock stability
The seal protection for slide gates are mainly for upper slide plate and upper nozzle; lower slide plate and lower nozzle. After one or two times of casting, lower slide plate and nozzle must be replaced and re-installed. The sealing materials could be gaskets made of fiber or fireclay. To ensure the high cleanliness of molten steel and the uniformity of internal quality of slab.

Alumina-carbon, alumina-zirconia-carbon, magnesia-alumina-spinel slide gate plates and corundum, alumina-carbon, mullite, magnesia-alumina-spinel upper and down slide nozzles are made of quality materials with phenolic resin binder through pitch impregnation in vacuum and mid temperature treatment. They are classified into high temperature sintered and unburned products. The products have the good thermal stability, erosion resistance to molten steel, corrosion resistance and long service life. They are widely used in 20-300t steel ladles and various tundishes to well control flow rate of molten steel with safety and easy switch.
