Control and Detection of Metallurgical Quality of Zinc Alloy Die Castings

(1) Lead and tin have an adverse effect on the corrosion resistance of the zinc alloy. Therefore, the vortex of the smelting zinc alloy and the smelting copper alloy cannot be used (because of lead and tin in the copper alloy), and must be strictly separated. If necessary, use zinc alloy scrap to melt the copper alloy vortex vortex furnace more than once.

(2) Zinc-aluminum alloy will react with iron at the melting temperature. Therefore, zinc-containing alloys containing iron are generally not smelted by cast iron vortex, and the iron smelting and casting tools used must be painted (sprayed) tightly. The refractory coating is separated from the alloy fluid.

(3) The chemical composition of the zinc alloy can be sampled in front of the furnace for chemical analysis or spectral analysis. The former is accurate and is a method of constant moon. The latter analysis is not very accurate, and is suitable for die castings with low mechanical properties and airtight performance requirements.

(4) The zinc alloy has low gas absorption, generally does not carry out gas test, and casts a bending sample to test the quality of the zinc alloy, after pouring 2

But refer to the metal type for the pre-furnace test method of copper alloy.

That is, water is cooled, and then one end of the sample is clamped on the vise.

3min, take the solidified sample out of the mold Angle to judge the mechanical properties of the alloy,with a hammer to break, according to the size of the force when breaking and the fracture of the sample Slightly judge the quality of alloy metallurgy.
