Abstract

The invention discloses a smelting method of a zinc alloy. The smelting method comprises the following steps: taking 99.0%-99.35% by weight of a Zn-Al4 alloy, 0.55%-0.9% by weight of an AlTi-5B intermediate alloy and 0.05%-0.15% by weight of ZnCl2 as raw materials for smelting; a power frequency coreless induction furnace is used as smelting equipment; a zinc liquid pump, a silicon carbide ceramic infusion tube with the output hole diameter of 45-50 mm and an H13 steel crucible serve as smelting tools, and the zinc alloy is manufactured through the three steps of raw material and equipment preparation, pre-preparation and smelting. The method is low in metal loss, controllable in cost, small in pollution, good in compactness and good in uniformity.

Description

technical field [0001] The invention relates to the technical field of metal material smelting, in particular to a zinc alloy smelting method. Background technique [0002] Zinc alloy occupies a unique position in the die-casting production of metal materials due to its advantages in casting performance and mechanical properties. Type solidification process, so it is impossible to determine the problem of the process intuitively. At present, many domestic die-casting enterprises still mainly rely on experience in the production of zinc alloy die-casting, and determine the final process plan through repeated mold repairs. This mode of production costs is high, the cycle is long, and the high experience dependence makes it difficult for young engineers to become an important part of the enterprise. Partly, it is not conducive to the long-term development of foundry enterprises. Numerical simulation can be used to analyze whether the process parameters are reasonable, predict...
