| Message: | Steel wire Wire drawing dieCemented carbide is made of refractory metal carbide (tungsten carbide, titanium carbide, tantalum carbide, etc.), with iron group metal cobalt or nickel as the bismuth metal. A metal material produced by a powder metallurgy process. It is used to make the core material of the wire drawing die. Its valuable characteristic is that it has high hardness, abrasion resistance, corrosion resistance, high temperature resistance, easy heat conduction and easy light application. Therefore, it has been used since it was applied to the wire drawing industry. A strong vitality and vitality. How to make the quality of the hard disk of the hard alloy fully exerted, so that the wire drawing can achieve high quality, high output and low consumption. In addition to its manufacturer, the product quality is wiped out, the mold making of the wire drawing industry is extremely important, otherwise, even the mold The billet is very good, and it is also a waste of the hard material of the hard sheet metal due to improper mold making. The material has not been used for its best. Because of this, the research work on the design of the drawing die hole has not stopped.Strain aging of high carbon steel wire The strain aging mechanism of steel wire means that after a large amount of cold working deformation of the steel wire, the lattice dislocation motion is very severe, the internal sliding plane is twisted, the crystal lattice is seriously distorted, and the steel wire structure becomes Abnormally dense, internally generating multiple stress fields. After staying at a higher temperature for a certain period of time, the cementite in the pearlite will be separated, and the resulting carbon atoms move in the stress field, move toward the center of the dislocation, and precipitate as carbides. In the dislocation, when it is further deformed, slippage is difficult. The macroscopic performance is that the tensile strength of the steel wire increases, and the bending and tors......url:http://www.qediamonddie.com |
