Xitoy OEM tomonidan tayyorlangan karbonli po'lat quymayo'qolgan mum sarmoyasini quyish jarayoni.Agar kerak bo'lsa, biz EN 10204 ga muvofiq quyma metallning 3.1 Material sertifikatini taqdim etishimiz mumkin. Mavjud tekshirish usullari: CMM tomonidan o'lchov sinovi, buzilmaydigan sinov, kimyoviy tarkib, mexanik xususiyatlar, qattiqlik sinovi, statik muvozanat, dinamik muvozanat, havo bosimi va suv bosimi.
Uglerod miqdori darajasiga ko'ra, quyish uchun uglerodli po'lat odatda past karbonli po'lat, o'rta karbonli po'lat va yuqori karbonli po'latga bo'linadi. Dunyodagi barcha mamlakatlarning quyma uglerodli po'latlari odatda ularning kuchiga ko'ra tasniflanadi va tegishli navlar ishlab chiqariladi.
Karbonli po'latning kimyoviy tarkibiga kelsak, fosfor va oltingugurtdan tashqari, boshqa kimyoviy elementlarda hech qanday cheklovlar yoki faqat yuqori chegaralar mavjud. Yuqoridagi shartlarga ko'ra, quyma uglerodli po'latning kimyoviy tarkibi kerakli mexanik xususiyatlarga ko'ra quyma tomonidan aniqlanadi.
Uglerodli po'lat quymalarining issiqlik bilan ishlov berish usullari odatda tavlanish, normalizatsiya yoki normalizatsiya + temperlemedir. Ba'zi yuqori uglerodli po'lat quyish uchun, söndürme va temperleme, ya'ni uglerodli po'lat to'qimalarining keng qamrovli mexanik xususiyatlarini yaxshilash uchun, ya'ni söndürme + yuqori haroratli temperaturadan ham foydalanish mumkin. Kichkina uglerodli po'lat quyma to'g'ridan-to'g'ri quyma holatidan so'ndirilishi va qattiqlashishi mumkin. Katta miqyosli yoki murakkab shakldagi uglerodli po'lat quyish uchun normalizatsiya qilingandan so'ng söndürme va temperli ishlov berish o'rinli bo'ladi.
