Embodiment 1
[0045] Mix carbon, silicon, phosphorus, sulfur, manganese, copper, lead and iron, and accurately weigh each raw material for melting. The melting temperature is 1460-1480°C. After melting, stand at high temperature for 15 minutes to make copper, manganese and other alloying elements Fully dissolved in the alloy liquid.
[0046] The above alloy liquid is prepared by a water-cooled metal mold centrifugal casting process to obtain a blank, which is poured using a single-station centrifugal pouring machine. Primary inoculation treatment (inoculant consumption 0.6wt%); then transfer to the fire pouring spoon for secondary inoculation, the bottom of the fire pouring spoon is placed with silicon strontium inoculant (inoculant consumption 0.2wt%), pouring after inoculation is completed, pouring The temperature is 1430°C-1450°C, the speed of the pouring machine is 1200 rpm, the thickness of the mold coating is 0.6mm, the mold preheating temperature is 260°C, the water supply time is 19...
Embodiment 2
[0063] Mix carbon, silicon, phosphorus, sulfur, manganese, copper, lead and iron, and accurately weigh each raw material for melting. The melting temperature is 1450-1470°C. After melting, stand at high temperature for 15 minutes to make copper, manganese and other alloying elements Fully dissolved in the alloy liquid.
[0064] The above-mentioned alloy liquid is prepared by a water-cooled metal mold centrifugal casting process to obtain a blank; a single-station centrifugal pouring machine is used for pouring, and the alloy liquid after standing is first poured into a large ladle, and a silicon-barium inoculant is placed at the bottom of the large ladle. Primary inoculation treatment (inoculant dosage 0.6wt%); then transfer to the fire ladle for secondary inoculation, place silicon strontium inoculant (inoculant dosage 0.2wt%) at the bottom of the fire ladle, and then pour, pouring temperature 1430°C ~1450°C, pouring machine speed 1200 rpm, mold coating thickness 0.6mm, mold ...
