Vertical zinc melting furnace for waste alloy recycling

Primarily used for the recycling of scrap alloys such as rod-shaped and block-shaped materials, it involves adding zinc as a flux to melt the cobalt phase at high temperatures, followed by crushing it into WC+Co alloy powder.

II. Process Principle:

WC + Co + Zn = WC + Co + Zn↑.
