Seamless Honed Pipe Cold Drawn Tubes are economical steels. Cold-drawn tubes include non-circular section, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetrical sections, etc., and are widely used in aviation, automobiles, shipbuilding, mining machinery, agricultural machinery, construction, , textile and boiler manufacturing. During the smelting process, scrap steel is added to the furnace together with the charge, and smelted according to the traditional process. Add deoxidizer and alloy after tapping. Molten steel is cast immediately after argon blowing. The molten steel after argon blowing and tempering is cast into a slab by a continuous casting machine. Due to the addition of rare earth elements in the steel, the cold-drawn pipe is purified and the content of inclusions is greatly reduced. Compared with ordinary carbon steel, cold-drawn tubes have better corrosion resistance in the atmosphere.
Cold-drawn pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable, convenient and quick to use, and have irreplaceable advantages of other pipes. It will be more and more used in construction engineering, and its use will become more and more popular, with broad prospects. The year before last, the overall development of my country's cold-drawn pipe industry was unbalanced. Under the current situation that the volume of the cold-drawn pipe industry is increasing rapidly, the source of raw materials is very tight, and the domestic supply is seriously insufficient. Basically rely mainly on imports to maintain development. The rise in iron ore has also increased the cost of stainless steel. It is difficult to compete in today's fierce market competition, which makes it difficult for enterprises to produce and operate.
