Q:How should we choose the spring material?: Large and medium-sized spring for load precision and stress higher, should choose cold drawn or cold drawn after polishing steel, for load precision and stress lower spring products, can choose hot rolled steel.

Q:Is spring steel manganese steel?: With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.

Q:What are the categories of springs?: A compression spring is spring under axial pressure, the material section in which are round, rectangular and is also useful multi strand steel rayon coiled spring, generally for pitch, compression spring shapes: cylindrical, conical, convex and concave and a small amount of non circular, will there is a certain gap between the ring and the ring compression spring, when subjected to external load when the spring contraction deformation, deformation energy storage.

Q:How to process Spring Steel: The available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to form bubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel.

Q:What's the spring material to?: 1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.

Q:What is an independent bagged spring?: Independent bagged spring is a spring with non-woven package, barrel type design can prevent the spring friction and swinging or noise, no influence between spring, elastic energy in accordance with the size of individual expansion, different weight average and proper support of various parts of the body to keep the spine straight, make sleep more comfortable. Bagged spring than ordinary spring production process is more complicated, the cost is higher, so the price is slightly expensive. But human health is obviously.

Q:Spring dynamometer and spring balance what is the difference: Spring dynamometer is a force measuring spring balance is to measure the quality of

Q:Cold rolled coil spring spring and difference ": Coil is to burn the red, generally large diameter to coil

Q:The glass door spring is broken. How much would it cost to change it?: Between 100 and 300 yuan, too cheap, then use less than half a year, but also replaced, the loss outweighs the gain.

Q:What's the manganese content of spring steel?: Refer to Baidu Encyclopedia: in accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.
