Does the smelting of nonferrous metals, graphite crucible and cast iron crucible which is easy to use?
The pollution of carbon to aluminum alloy and copper alloy should be less than that of iron to aluminium alloy and copper alloy, but the iron crucible is durable and easy to use
I can't decide which is good. I just want to talk about the smelting methods of some nonferrous alloys(1) cast aluminium alloy ZL101, cast iron crucible;(2) casting brass, H62, graphite crucible;(3) cast magnesium alloy ZM5, steel plate welding crucible(4) casting tin bronze, 5-5-5, fused magnesia, medium frequency furnace smelting
