(1) In order to improve the quality of special-shaped spring steel, the industrial production is relatively developed. In our country, the refining technology outside the furnace, steel rolling process, new cold rolling and on-line automatic identification and control system are generally adopted.

In order to ensure the composition of steel, reduce the content of vapor and various nonmetallic materials, smelting in large space furnace or coke oven, refining in ladle outside the furnace, so as to reduce the oxygen content (molar mass) to (0.0021 ~ 0.0010)%, and produce ultra pure steel, which greatly improves the design scheme of special-shaped spring and in-situ stress in work.

The rolling process has been used in the production of special-shaped spring steel for customized variable diameter spring machine. Steel rolling can reduce shrinkage porosity, reduce secondary air oxidation and improve surface carburization according to electromagnetic induction mixing and ultra-low temperature forging, so that the mechanism and performance are stable and even.

The precision and surface quality of the stainless steel plate can be improved by using the split continuous extrusion press. In addition, the stainless steel plate can be symmetrical along the long and short microscope mechanism by the automatic constant force spring machine. In the whole process of cold rolling, in order to ensure the surface quality of goods, automatic identification and operation on line are adopted. In order to suit the production and manufacture of special-shaped spring galvanized flat steel with variable cross-section, a new cold-rolled forming technology of austenitic stainless steel was developed and designed, that is, the steel was heated to the austenitic stainless steel area and then quenched to the metastable austenitic stainless steel area to carry out plastic deformation processing and hot processing. This kind of processing technology can not only reduce the plastic deformation of steel, but also improve the compressive strength. In addition, the properties of special-shaped spring steel can be improved by quenching and tempering treatment and surface hardening after rolling.

(2) The development trend of carbon steel the key function of aluminum alloy element is to customize steel belt quenching furnace, improve structural mechanical properties, improve processing performance and award some unique properties. SiCr steel has been used in cylinder and suspension system. Si is an element of stress relaxation resistant aluminum alloy. Adding V and Mo to SiCr steel can produce sicrv and sicrmo steel, which can improve fatigue life and anti relaxation performance. In addition, SiCr drawing stainless steel wire has better anti relaxation performance when working at high temperature than piano stainless steel wire and carbon special-shaped spring stainless steel wire which mainly uses customized spring. With the high-speed practical application of diesel engine, Ti aluminum alloy with good anti flutter performance, light quality and small elastic die has been widely used, and its compressive strength reaches 2000mPa.
