Embodiment Construction
[0045] The present invention will be described through examples below, and it should be noted that these examples are only exemplary and do not constitute any limitation to the present invention.
[0046] Preparation of spring steel
[0047] The chemical composition of embodiment and comparative example is shown in Table 1, and its preparation process is as follows:
[0048] The first step, electric arc furnace smelting - ladle refining - continuous casting pouring
[0049] Primary smelting of molten steel in a 60-ton electric arc furnace; refining in a 60-ton ladle; continuous casting; production of 90×90mm 2 ~360×360mm 2 Qualified continuous casting slabs with section dimensions:
[0050] (1) Initial smelting: Low P and S scrap steel, cut ends and high-quality pig iron are used as charge materials; low-carbon chromium, low-carbon manganese, etc. should be prepared for alloys; reducing agent: calcium carbide, carbon powder, crystalline silicon, etc.; oxidation period: freq...
