Abstract
The invention provides a manufacturing technology of a high performance metal material. The manufacturing technology comprises the following steps: smelting the steel through a common steel-smelting technology, then casting the steel into rod-shaped blanks, wherein the steel is composed of the following elements in percentage by weight: 0.08 to 0.6 wt% of C, 0.6 to 4.0 wt% of Mn, 0.1 to 0.9 wt% of Si, 0 to 3 wt% of Cr, 0 to 0.5 wt% of S, and the balance being Al; and the diameter of each rod-shaped blank is 30 to 50 mm; forging the blanks at a high temperature, then heating the blanks to a temperature of 700 DEG C, maintaining the temperature for one hour; cooling in oil or air, maintaining the blank temperate in a range of 500 to 650 DEG C for 2 hours, and then carrying out a tempering treatment. The manufacturing technology has the following advantages: cheap elements and a simple and feasible thermal treatment technology are adopted to obtain a metal material comprising proper portions of ferrite-pearlite, sorbite, and bainite tissues, the metal material has an excellent comprehensive performance and can meet the requirements on manufacturing reinforced screw rods. Through the provided technology, reinforced screw rods with excellent performances can be manufactured, the dependence on the imported reinforced screw rods can be reduced, and moreover, and the technology and raw materials are very cheap.
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
For existing technical deficiency, the invention provides a kind of high-performance metal materials and manufacturing process thereof.
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, pours into pole blank with conventional process for making, makes the weight percent of each composition in steel be:
