Umumiy kamonli po'lat elektr o'choq, ochiq o'choq yoki kislorod konvertori tomonidan ishlab chiqarilishi mumkin; sifatli yoki maxsus xususiyatlarga ega yuqori-sifatli prujinali po'latni elektroshlakli pech yoki vakuumli pechda tayyorlash mumkin. Bahor po'latidagi uglerod, marganets, kremniy va boshqa asosiy elementlarning belgilangan tarkib oralig'i tor va kimyoviy tarkibi eritish paytida qat'iy nazorat qilinishi kerak. Kremniy miqdori yuqori bo'lsa, pufakchalar kabi nuqsonlar paydo bo'lishi oson va ingot zarb va prokatdan keyin to'g'ri sovutilmaganda oq dog'lar paydo bo'lishi oson. Shuning uchun, eritish uchun xom ashyo gaz va inklyuziyalarni iloji boricha olib tashlash va eritilgan po'latning haddan tashqari qizib ketishiga yo'l qo'ymaslik uchun quritilishi kerak.
Bahor po'lati prokat paytida dekarburizatsiya va sirt sifatiga alohida e'tibor berish kerak. Chelik yuzasi jiddiy dekarburizatsiyalanganda, u po'latning charchoq chegarasini sezilarli darajada kamaytiradi. 70Si3MnA kabi yuqori kremniyli kamonli po'lat uchun grafitlanishdan qochish uchun ehtiyot bo'lish kerak. Shuning uchun, issiq ish paytida, grafitizatsiya hosil bo'lishi osonroq bo'lgan harorat oralig'ida (650-800 daraja) uzoq vaqt qolmasligi uchun dumalab turish harorati juda past bo'lmasligi kerak (850 darajadan katta yoki unga teng).
Springs are used under impact, vibration or long{{0}}term alternating stress, so spring steel is required to have high tensile strength, elastic limit and high fatigue strength. In the process, the spring steel is required to have a certain hardenability, not easy to decarburize, and good surface quality. Carbon spring steel is high-quality carbon structural steel with a carbon content of WC in the range of 0.6 percent -0.9 percent . Alloy spring steels are mainly silicon-manganese steels, their carbon content is slightly lower, and their performance is mainly improved by increasing the silicon content Wsi; in addition, there are alloy spring steels of tungsten, tungsten and vanadium. In recent years, combined with our country's resources and according to the requirements of new technologies for automobile and tractor design, new steel grades with boron, niobium, molybdenum and other elements added to silicon-manganese steel have been developed, which prolongs the service life of the spring and improves the quality of the spring.
