The technological means to improve the performance of SA572 grade 65 carbon steel plate sheet

Hot Rolled Plates SA572 grade 65 carbon steel plate sheet MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.

The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the SA572 grade 65 carbon steel plate sheet manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.

SA572 grade 65 carbon steel plate sheet, Q390B steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately. Rare earth elements are added to the steel, the Q390B steel plate is purified, and the content of inclusions is greatly reduced.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe SA572 grade 65 carbon steel plate sheet is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
