Furnace rollers are essential processing equipment in the steel plate smelting production process. In order to ensure the requirements of steel plate production, furnace rollers also have high use requirements. Furnace rollers are a typical Centrifugal Casting pipe fittings. They are one of the important components for supporting and transporting slabs in metallurgical equipment and are widely used in steel plate continuous casting and rolling production lines.
During the rolling process, the steel billet must first be continuously and stably heated to a rolling temperature of 1050-1150°C in the heating furnace, and the slab must be stably supported by the furnace roller to ensure smooth and uniform transportation. Since the middle section of the furnace roller is directly installed in the billet calcining furnace, the furnace gas temperature during the production process is as high as about 1150°C, and it is usually made of high-temperature alloy materials.
At the same time, since the support part in the middle of the furnace roller is directly installed in the furnace, and the cone section and the bearing support part are respectively installed in the furnace wall and outside the forging furnace, the temperature gradient of different parts of the furnace roller is very large. Therefore, the furnace roller is generally welded by the cylinder, cone and shaft. In order to reduce the burning loss on the inner surface of the cone, a heat insulation board is designed on the inner side of the cone. In order to ensure the smooth transportation of high-temperature slabs, the roller shaft must not be deformed and the outer roller ring must be heat-resistant and wear-resistant.
