Direct Support for Hot Steel
This product is a key part that supports steel billets inside the reheating furnace. It directly contacts high-temperature red steel. It must withstand extremely high temperatures and wear. Our factory has deep experience in heat-resistant steel casting. We offer three material solutions for different furnace temperature zones. The first is for medium temperature zones. Service temperature does not exceed 1050°C. Material is ZG40Cr25Ni20Si2. Hardness is HB 210 to 260. The second is for high temperature zones. Service temperature is 1050 to 1150°C. Material is ZG40Cr28Ni48W5Si2. Hardness is HB 230 to 280. The third is for ultra-high wear conditions. Material is UMCo50 cobalt-based alloy. Hardness is HRC 44 to 50. Customers choose the best material based on furnace temperature. The Heat Resistant Slide Block is engineered for high-temperature support.
Dimensional Precision and Casting Quality
Dimension tolerance for this product is controlled within ±0.2mm. Working surface flatness is controlled within 0.05mm per meter. These precision levels ensure smooth contact with the billet. We use precision investment casting for this product. This process ensures dimensional accuracy and surface quality. We do magnetic particle inspection before shipment. We check the working surface for cracks and porosity. Cracks and porosity cause failure at high temperature. Every Heat Resistant Slide Block passes strict inspection.
Thermal Shock Resistance Testing
This product needs excellent thermal shock resistance. Our products go through strict testing. Test conditions are 1100°C high temperature directly into room temperature water. No cracking after 50 cycles. This test verifies thermal shock resistance. Our slide blocks stay intact during repeated heating and cooling. We have accumulated rich process parameters in heat-resistant steel casting. These parameters ensure stable high-temperature performance. The Heat Resistant Slide Block delivers reliable furnace service.
Selection Support and Service
This product has been used on reheating furnaces in many domestic steel mills. Customers report long service life. We also provide selection advice based on your service temperature. Our technical team helps optimize slide block installation. Choose our Heat Resistant Slide Block for reliable high-temperature support.
