The pre-melt pot is specially designed to improve the quality of hot strip steel plating products, according to the technological formula with good aluminium, zinc and other trace elements alloy ingot in the pre-melt pot uniform melting and amalgamation, by adding the ingot ,the liquid surface will be higher than that of liquid level and the overflow, again through the launder to the GL pot, add the consumption of plating solution. The pre-melt pot general arrangement in the drive side (main pot)

The launder is composed of launder body, refractory crack of precast block lining, and its own burner.

The launder is mainly used to PM pot of molten liquid overflow to the GL pot, to supplement the main pot aluminum liquid zinc consumption. Make the overflow zinc liquid temperature is close to main pot temperature.so that the production line work to be smooth and fast.
