Slide gate plate 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.

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.

Operators often see cracks and damage in ladle shrouds, long nozzles, and refractory parts. This happens because of a few main reasons:

·        Fast temperature changes can cause thermal shock and peeling.

·        Mechanical stress comes from handling, hitting, or working forces.

·        Hot slag and molten steel can wear down and get into the parts.

·        Material problems like tiny holes or mistakes made during making.

·        Issues with design, how things line up, or how they fit together.
