Embodiment 1
[0017] Pouring by centrifugal casting method High-speed steel composite roll, the outer layer is boron-containing high-speed steel 1, the thickness of the outer layer is 45mm, the roll core is ductile iron 3, the material of the present invention is used as the middle layer 2, the thickness of the middle layer 2 is 5mm, and the middle layer 2 adopts a 500 kg intermediate frequency induction Electric furnace smelting. First, scrap steel, pig iron and copper plate are mixed and heated and melted. Elements such as boron, vanadium, molybdenum, niobium, cobalt, tungsten and chromium are mainly brought in by the outer boron-containing high-speed steel, and the insufficient part is supplemented by adding ferroalloy. After the composition is adjusted before the furnace, the temperature is raised to 1525°C, then aluminum is used for deoxidation, and then ferrotitanium is added and released from the furnace. When the furnace is released, the molten steel is first inoculated with silico...
Embodiment 2
[0021] Pouring by centrifugal casting method High-speed steel composite roll, the outer layer is boron-containing high-speed steel 1, the thickness of the outer layer is 62mm, the roll core is ductile iron 3, the material of the present invention is used as the middle layer 2, the thickness of the middle layer 2 is 8mm, and the middle layer 2 adopts a 500 kg intermediate frequency induction Electric furnace smelting. First, scrap steel, pig iron and copper plate are mixed and heated and melted. Elements such as boron, vanadium, molybdenum, niobium, cobalt, tungsten and chromium are mainly brought in by the outer boron-containing high-speed steel, and the insufficient part is supplemented by adding ferroalloy. After adjusting the composition before the furnace, the temperature is raised to 1538°C, then aluminum is used for deoxidation, and then ferrotitanium is added and released from the furnace. When the furnace is released, the molten steel is first inoculated with silicon-...
Embodiment 3
[0025] Pouring by centrifugal casting method High-speed steel composite roll, the outer layer is boron-containing high-speed steel 1, the thickness of the outer layer is 50mm, the roll core is ductile iron 3, the material of the present invention is used as the middle layer 2, the thickness of the middle layer 2 is 6mm, and the middle layer 2 adopts a 500 kg intermediate frequency induction Electric furnace smelting. First, scrap steel, pig iron and copper plate are mixed and heated and melted. Elements such as boron, vanadium, molybdenum, niobium, cobalt, tungsten and chromium are mainly brought in by the outer boron-containing high-speed steel, and the insufficient part is supplemented by adding ferroalloy. After adjusting the composition before the furnace, the temperature is raised to 1520°C, then deoxidized with aluminum, then added ferro-titanium and taken out of the furnace. When the furnace is released, the molten steel is first inoculated with silicon-calcium-barium,...
