多年专注精密管生产的厂家

A single position gas cooled quenching furnace is cooled by jet cooling in the heating chamber after heating and holding. The cooling rate of gas cooling is faster than that of oil cooling, and quenching is lower than that of molten salt isothermal quenching. Therefore, continuous injection of cold chamber pressure, large flow rate, the use of molar mass less than nitrogen and argon inert gas helium and hydrogen are the mainstream of vacuum quenching technology development.

使流体管道的成本是很便宜的，和管道本身的强度很高，已被广泛应用于交通运输。流体管道可分为无缝管和焊接管，如果它们根据制造工艺进行区分。焊接钢管可分为其他类型的焊接管、比尔螺旋焊管、埋弧公司经营高质量无缝钢管销售地区涵盖所有省份和地区，除海南外，其他省份和地区。

硬度与变形编辑器采用两种模式，一种是研究不同变形程度对硬度的影响，另一种是研究不同温度对性能的影响。冷变形的强化在实际生产中具有重要意义。First of all, this is an important means of strengthening materials, especially for materials that cannot be strengthened by heat treatment.
