High-Temperature Slide Gate Lubricant
High-Temperature Slide Gate LubricantA water-based system formulated primarily with ultra-fine natural flake graphite, with performance benchmarked against equivalent Taishin products from Japan. It combines slide gate plate surface repair with sliding lubrication.
• Graphite paste: Applied to machined slide gate plate surfaces to fill small scratches and pits and provide high-temperature oxidation protection. Spread evenly with a scraper and dry at low temperature.
• Slide gate lubricant: Used with graphite paste and applied by roller or brush to plates preheated at low temperature. Residual heat evaporates the water before packing and shipping.
Key Benefits
• Smooth, jam-free sliding: A low friction coefficient provides smooth movement and prevents surface scratching and roughening.
• Longer plate life: Resistance to slag adhesion, wetting and oxidation reduces attack from molten steel and slag.
• Protection against steel leakage: A dense protective layer improves surface smoothness and reduces the risk of solidified steel penetration and burn-through.
• Environmental and safety benefits: A water-based formulation free of heavy metals and benzene-based solvents, with no fire or explosion risk. Cures by air drying at ambient temperature or baking at low temperature.
