Problems solved by technology

[0002] The zinc alloy material produced by the existing method lacks the on-line degassing and purification means of the melt, so the internal quality of the zinc alloy material is poor, and because the ordinary crystallizer is used for casting, the surface of the zinc alloy material often has the phenomenon of pulling cracks, which cannot be It meets the standard of extrusion, and the yield of ingot is only 60%
[0003] Existing explosion-proof tools are generally made of beryllium bronze, which is relatively high in cost and limited in application; in addition, its hardness is small, which makes it difficult to meet the requirements of some places and cannot meet the requirements of some places
[0004] The surface oxidation resistance, temperature grade, strength at high temperature, and processing performance of existing zinc alloy materials need to be improved
