The precision rolling mill is the core and key equipment for seamless steel pipe precision machining production, widely used in our factory's large-scale steel pipe production line. This article mainly introduces the equipment volume and core material composition of the precision rolling mill in the factory area, elaborates on the working principle and standardized operation process of its limited motion core rod precision rolling, and briefly describes the quality characteristics and applicatio

30CrNi3MoV is a medium‑carbon low‑alloy high‑strength structural steel specified in GB/T 3077‑2015. Its seamless steel tubes feature high strength, high toughness and outstanding fatigue resistance, widely used in high‑load high‑end equipment including aerospace, military industry, heavy‑duty machinery and energy facilities. Alloying elements Cr, Ni, Mo and V jointly contribute to its superior mechanical properties, while disadvantages include high material cost, difficult machining & welding an

12Cr1MoVG steel tubes are specially designed for boiler superheaters. Containing chromium, molybdenum and vanadium alloying elements, their creep resistance is more than three times superior to ordinary carbon steel under operating temperatures of 300℃‑580℃. Fully compliant with GB/T 5310 standard, they feature low budget and high cost‑performance, meeting your requirements in performance, compliance and cost.
