The use of cold-rolled precision light tubes and related knowledge are numerous. As long as the materials are selected correctly, they can be used in the chemical engineering of automobile train construction machinery.
Different applications have different requirements for finish, generally Ra is from 0.2 to 0.8.
45# cold-rolled precision bright spot price of 5200 yuan / ton.
The tolerances and out-of-roundness of the inner and outer diameters of precision seamless steel tubes produced by our company are less than 10 wires, and the wall thickness tolerance is less than 8 wires, and the straightness is less than 0.1 mm/m. The product has a bright appearance, a smooth inner wall, a uniform wall thickness, and a good straightness. Applicable to hydraulic machinery, auto parts, bearings, DC motor housing, instrumentation and other fields. Can greatly reduce your production costs. The company specializes in the production of high-precision cold-rolled pipes of various specifications of 20# and 45# steel, internal honing pipes and deep-hole honed honed honed seamless steel pipes, diameters Φ 25mm-Φ98mm, wall thicknesses 1.5mm-16mm carbon steel, alloys Steel, stainless steel, non-ferrous metals and other specifications of precision bright finishing tube, can be processed. The cold-rolled precision light tube produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. Steel pipe bore can be divided into round, splined, plum-type and other widely used in automobiles, motorcycles, power, petrochemical, shipbuilding, aerospace, bearings, pneumatic components, fuel tanks, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, GCr15, 40Cr. 16Mn and so on. And can be customized according to user needs a variety of national standard non-standard precision tube. Special materials and specifications can be booked in advance.

The production process of copper in China is dominated by copper concentrates and pyrotechnic smelting of blister copper. The status quo is that the processing capacity is greater than the smelting capacity, smelting capacity has greatly exceeded the support capacity of copper concentrate, copper concentrate resources and scrap copper imports are required. Statistics show that in the 21st century, the output of domestic copper concentrate has not been significantly increased, maintaining an annual output of 600,000 tons (copper content, the same below), by the end of 2007 will form nearly 3.7 million tons of smelting capacity, far exceeding By then China's copper concentrate resources and the protection of the capacity of the international market may provide the amount of copper concentrate. The production capacity of copper mines in China can only meet 40% of the smelting capacity.
