Unburned Slide Gate Plate for Steel Industry
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle Slide Gate System for Steel Tapping Control
Size: Custom slide gate plate geometry per ladle slide gate system design (free engineering on request)
Products Overview
Our Unburned Slide Gate Plate is a high-performance unburned slide gate plate engineered for ladle slide gate system service. The product family is manufactured from corundum, mullite, and high-quality clinker clinker as the main raw materials, with flake graphite, silicon carbide, and silicon metal powder, by high-pressure molding, low-temperature heat treatment, and grinding. The product family features high medium-and-high-temperature strength, strong oxidation resistance, good thermal shock resistance, small sliding surface wear, and small injection hole expansion diameter, fully meeting the requirements of the casting process with good use effect.
The Unburned Slide Gate Plate product family is offered in four engineering-proven MS chemistry grades. The CH-MS65 grade features Al2O3 content minimum 65% and C content minimum 5% for general ladle slide gate service. The CH-MS75 grade features Al2O3 content minimum 75% and C content minimum 5% for higher-alumina ladle slide gate service. The CH-MS80 grade features Al2O3 content minimum 80% and C content minimum 5% for high-alumina ladle slide gate service. The CH-MS85 grade features Al2O3 content minimum 85% and C content minimum 2% for highest-alumina ladle slide gate service. All four grades deliver Bulk Density minimum 2.90 to 3.00 g/cm³, Apparent Porosity maximum 8% to 10%, and Cold Crushing Strength minimum 70 to 100 MPa depending on grade.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Unburned Slide Gate Plate grade is engineered to ASTM, GB/T, and ISO refractory standards.
