Abstract
A high-performance metal material preparation technology comprises the following steps: smelting through a routine steelmaking process, and casting to form a round rod blank, wherein the round rod blank comprises 60.5-70.6wt% of Cu, 18.5-20.4wt% of Zn, 0.3-0.9wt% of As, 0.8-1.7wt% of Sn, 2.6-4.2wt% of Si, 1.2-2.3wt% of Mn, and the balance of Al, and the diameter of the rod blank is 30-50mm; carrying out high temperature forging, heating the blank to 700DEG C, maintaining the temperature for 1h, carrying out oil cooling or air cooling, maintaining the temperature in a range of 500-650DEG C for 2h, and tempering; and processing to form a part with the microstructure containing proper proportions of ferrite-pearlite, sorbite and bainite structures, the tensile strength of 500-1000MPa and good plasticity and toughness. A metal material prepared through the preparation technology has the advantages of good mechanical performances, corrosion resistance, heat resistance, close texture and high quality.
Description
Technical field
The present invention relates to a kind of high-performance metal materials, particularly a kind of high-performance metal materials manufacturing process.
Background technology
Reinforcement leading screw is the important special mould clamp of one of heavy machine tool holding workpiece.Its consumption on heavy machine tool is very large, is a kind of key part of heavy machine tool.Rely on certain house journal's technical monopoly external to produce in the world, production technology holds in close confidence and its import price costliness.Thus developing reinforcement leading screw production technology is important research topic, in view of the stringent technical of external reinforcement leading screw technology is maintained secrecy, domesticly technically still belongs to blank in this regard, does not up to the present also grasp its core technology, thus also fail to form production technology.
Summary of the invention
The object of the present invention is to provide a kind of weather-resistant, good mechanical property, wear resistance is high, solidity to corrosion good, winter hardiness is good, good heat resistance, good fluidity, quality are tight, quality is high practical metallic substance manufacturing process.
To achieve these goals, the technical solution used in the present invention is: a kind of high-performance metal materials and manufacturing process thereof, after smelting with conventional process for making, pour into pole blank, described pole blank comprises following composition: copper, zinc, arsenic, tin, silicon and manganese, the weight percent of each composition is: described copper accounts for 60.5%-70.6%, described zinc accounts for 18.5%-20.4%, described arsenic accounts for 0.3%-0.9%, described tin accounts for 0.8%-1.7%, described silicon accounts for 2.6%-4.2%, described manganese accounts for 1.2%-2.3%, all the other are Al, rod base diameter is 30-50mm, after high temperature forges, blank heating was to 700 DEG C of insulations 1 hour, oil cooling or air cooling, again after 500-650 DEG C of insulation 2 hours temper, be processed into part, make its microstructure be respectively ferrite-pearlite, sorbite, the bainite structure of suitable proportion, its tensile strength is at 500-1000MPa and have good plasticity and toughness.
Beneficial effect of the present invention: the present invention, by manufacturing process, can obtain a kind of good mechanical property, have corrosion-resistant, that thermotolerance, quality are tight and quality is high metallic substance.
