Spring steel wire Uses:

Spring wire is mainly used in locomotives, vehicles, automobiles, tractors, aircraft and a variety of coil spring spring.

Hot forming spring heat treatment diameter or plate thickness greater than 10-15mm large spring, multi-purpose hot-rolled wire drawn wire rod or steel plate made of.

Processing and heat treatment: the first spring steel wire heated to a temperature higher than the normal quenching temperature of 50-80 ℃ under the conditions of hot-rolled forming, and then quenched in the tempering tempering, to obtain excellent flexibility and fatigue strength of the tempering sorbite. Spring steel wire quenching heating should be used with less oxygen or no oxidation equipment such as salt bath furnace, protective atmosphere furnace, to prevent oxidation decarburization.

Spring steel wire after heat treatment should also be shot peening, strengthen the surface, resulting in residual compressive stress, improve fatigue strength.

Hot-rolled spring steel wire used in the process are: flat steel cut -> heat bending forming after heat quenching + tempering + shot peening -> packaging.

Cold forming spring heat treatment diameter of less than 8mm of the spring, cold-rolled steel wire commonly used cold-rolled forming. Cold-drawn steel wire manufacturing process and follow-up heat treatment, mainly in the following three categories:

① lead bath cold drawn steel wire drawing the first three consecutive wire drawing, the total deformation of 50%, followed by heating to Ac3 above the temperature of its austenitizing, followed by 450-550 ℃ lead bath in the isothermal treatment, Body into sorbite tissue. Yield strength of 1600Mpa, cold roll forming, annealing at 200-300 ℃ stress can be.

② oil quenching and tempering steel wire drawing to size, the oil quenching and tempering. The strength of such wire is inferior to that of lead-treated steel wire, but the performance is uniform and the cost is low. After cold roll forming, a stress-relieving treatment is performed.

③ annealed steel wire drawing the wire to the required size, and then annealing. After the softening of the cold-rolled steel wire forming, subject to quenching after tempering in the temperature to get the required mechanical properties. Alloy elements in the spring wire in the main role is to improve the mechanical properties, improve process performance and to give some special properties (such as high temperature, corrosion resistance) and so on.
