求翻译：弹簧多数都要通过热处理来实现产品性能要求的。为了提高弹簧的力学性能，对热轧后大截面（厚度或直径5-40mm）钢料（圆钢、扁钢等）在热状态下经卷制成后，再进行淬火回火处理；对热轧后截面较小的钢料，经退火软化后，在冷状态下卷制成形，再进行淬火回火处理。是什么意思？

Spring the majority go through heat treatment to achieve the product performance requirements. To heat in order to improve the mechanical properties of the spring, large cross section (thickness or diameter of 5-40mm) after hot rolling steel material (round steel, flat steel, etc.) made by the volum

Most of it is you want to spring by heat treatment to achieve product performance requirements. In order to increase performance of the springs, the hot strip mill mechanics after the cross-sectional thickness or diameter of 5 - 40 MM) steel (steel, flat steel, etc. ) in the state, made by the volum

The spring most all must realize the product performance requirement through the heat treatment.In order to enhance the spring mechanics performance, after the hot rolling big section (thickness or diameter 5-40mm) the steel materials (round steel, flat steel and so on) the scroll sutra makes after

Most of spring had to be achieved through heat treatment product performance requirements. In order to improve the mechanical properties of spring, after hot rolling big section (5-40mm thickness or diameter) steel (steel, flat steel, and so on) after let-made in a hot state, and then quenching temp
