Embodiment Construction

[0010] Take 60.8% of raw material zinc, 28.6% of aluminum, 9.8% of intermediate alloy copper and aluminum (wherein the weight ratio of copper to aluminum is 1:1), and 0.8% of cobalt and aluminum (wherein the weight ratio of cobalt to aluminum is 1:10). The intermediate alloys copper-aluminum, cobalt-aluminum and aluminum are heated together to 850°C, and then the temperature drops to about 400°C after adding zinc, and then heated to 730°C, put into the ladle, and then add dry straw or straw for anti-corrosion. Oxidation treatment, so that it can cover the surface of the molten metal, after burning out, pour the molten metal through a sink into a thin iron plate mold at a temperature of 480°C, put the mold in 80°C hot water to cool, and then cast it.

Abstract

This invention discloses a method to produce a high strength of extension, low coefficient of friction, strong toughness, low expansion zinc alloy. The weight of ingredients is as follows: zinc is 55-65%, aluminum is 20-30%, intermediate alloy Al-Cu is 10-15%, and Co-Al is 1-2%. Heating the intermediate alloy and aluminum to 800-850 deg.C, after adding into zinc, the temperature of the mixture reaches 700-750 deg.C, then putting the mixture into the burning box and doing antioxidation, decanting it into the model with the temperature of 480-550 deg.C, putting the model into the water with the temperature of 40-80 deg.C to cool, at last we can get the alloy. The strength extension of this zinc alloy is 395-410Mpa, linear expansion factor is 17a*10-6, the hardness is 140-165HB, each physical index of it exceeds the characteristic of tin bronze, it can be as the succedaneum of tin bronze. It can be applied to axletree, axile bush, wormgear, nut and guide rail plate of numerical control machine, and it is a perfect wear resistant material.

Description

technical field [0001] The invention relates to the technical field of metallurgical material manufacturing, in particular to a high-strength, tough, low-expansion zinc-based wear-resistant alloy and a production process thereof in the technical field of metallurgical material manufacturing for metallurgical industrial plates, rods and pipes. Background technique [0002] At present, the production of zinc-based alloys has been mastered by everyone. For general zinc-based alloy materials, 55-65% zinc, 20-30% aluminum, 5-15% copper and 0.2-2% magnesium are used for melting, casting, Unmoulded after cooling. Its disadvantages are: low melting point temperature, large expansion coefficient, hot gas cannot be discharged normally during the pouring process, and pores are generated, resulting in large processing allowance, increased raw material loss, and increased product cost. In the cooling process, due to the use of sand molds and cast iron molds, the cooling speed is slow, s...
