With the acceleration of the development of modern industrialization, machinery and equipment appear more and more frequently in people's lives, and the pace of people's life is getting faster and faster. The demand for various dairy products, beverages, and fast food is gradually increasing, and it is also Pulled the development of the heat treatment steel belt industry. Heat treatment steel strip is widely used in the market, bringing more kinds of products to people's life and bringing benefits to many manufacturers. Heat treatment steel strip is suitable for die cutting, etching die, corrosion die, large circular saw blade matrix, machine tool guide rail, railway connection steel sheet and military products, etc. At present, this kind of large-size heat treatment high-strength steel strip is completely imported and subject to strict restrictions from exporting countries.

According to the production method, heat-treated steel strip can be divided into hot-rolled heat-treated steel strip and cold-drawn (rolled) heat-treated steel strip. Hot-rolled heat-treated steel strips include round steel or trapezoidal steel for manufacturing coil springs, torsion bars, and flat steel for manufacturing leaf springs; cold-drawn (rolled) heat-treated steel strips include cold-drawn steel wires for manufacturing small-sized coil springs and cold-rolled steel strips for manufacturing springs and various spring sheets. Alloy heat treatment steel strip usually contains manganese, silicon, chromium, molybdenum, tungsten, vanadium and trace boron. These alloying elements can improve the hardenability of steel. Manganese and silicon are dissolved into ferrite to improve the yield strength. Chromium, tungsten and vanadium can improve the elasticity, yield ratio and heat resistance of steel. The main products of Mudu Yongchang Metal Products Factory in Wuzhong District of Suzhou City include various cold rolled steel strips, heat treated steel strips, spring steel strips, 65 manganese steel, 65mn steel strips, 60 steel, 50 steel, various specifications of ordinary steel strips, 195, 235, T8, etc. In view of the changes in the market, our company has made a decision to add a heat treatment production line that can produce ultra-thick and ultra-wide products in a timely manner. The production line is designed to produce heat-treated steel strips with a thickness of 6.0mm or less and a width of 450mm or less.
