Enclosed type method and device for conveying zinc alloy liquor and casting zinc alloy ingot

Abstract

The invention relates to a method and a device for casting a zinc alloy pig. The method comprises the following steps: melting solid zinc into zinc liquid and adding an alloying element into the zinc liquid to alloy the zinc liquid, then pumping out the zinc liquid, and casting the zinc alloy pig through a pipeline in an airtight conveying mode. The device comprises a melting device, a conveyer, a casting device, and a pumping device, wherein the pumping device is an immersible pump type zinc liquid pump which is arranged in an airtight container communicated with the melting device. The method allows the zinc liquid to flow under the airtight condition, reduces the slag rate in the process of alloy casting, improves the quality of an alloy product, cancels the operations of blow on and stop off, reduces potential safety hazards in the production process, reduces the labor intensity of workers, improves the labor productivity, and realizes the automation of casting flow control.

Description

technical field [0001] The invention relates to a production method and device for metal alloy ingots, in particular to a casting method and device for zinc alloy ingots. Background technique [0002] The general production process of zinc alloy ingots is to melt solid zinc into a liquid state, add various additive elements to prepare an alloy liquid, and then cast it into a mold. Since the temperature of the zinc alloy liquid reaches 500°C, the requirements for equipment are very high. A self-flowing open chute is used to convey the zinc alloy liquid to the mold for casting, and its production equipment includes an alloy furnace, an open chute for conveying the zinc alloy liquid, and a casting mold. The zinc alloy liquid flows from the zinc outlet at the bottom of the alloy furnace to the chute, and then flows through the chute to the mold to be cast into alloy ingots. The flow adjustment method of the alloy liquid is to set a furnace blocking cone at the zinc outlet, which...

AI Technical Summary

Problems solved by technology

The above data show that this casting method has high energy consumption and a high rate of oxidized slag, which needs to be improved

[0003] On the other hand, one of the prerequisites for the use of closed-type alloy liquid transportation is that there is a pipeline suitable for zinc alloy liquid transportation. At present, there are no formed pipes suitable for zinc alloy liquid transportation on the market.
