我国与德国德马克公司联合设计、制造的φ170mm无缝钢管热轧生产线于1993年7月30日在大冶钢厂试轧成功。在半个月的试生产中,已轧出500多吨合格的钢管,整个生产线达到了80年代末的世界先进水平。大冶钢厂φ170mm无缝钢管厂项目,是国家“八五”重点工程之一。是我国生产轴承管为主的唯一的高精度无缝钢管生产基地。该热轧管生产线由环形加热炉、液压式定心机、锥形穿孔机、阿塞尔轧管机、芯棒循环系统、高速杠杆式切头锯、再加热炉、毛管高压水除鳞装置、十二机架二辊式减径机、回转定径机,高速杠杆式切割取样锯、冷床、毛管称重装置、电气控制系统、PLC微电脑自动控制统系、液
China and Germany Demark company jointly designed and manufactured φ170mm seamless hot-rolled steel production line in July 30, 1993 at Daye Steel trial success. In half a month trial production, has rolled out more than 500 tons of qualified steel pipe, the entire production line reached the world advanced level in the late 1980s. Daye Steel φ170mm seamless steel pipe plant project is the country “Eighth Five-Year” one of the key projects. It is the only high-precision seamless steel pipe production base mainly producing bearing pipe in our country. The hot rolled pipe production line consists of a ring furnace, a hydraulic centering machine, a cone piercing machine, an Asiler tube rolling machine, a mandrel circulation system, a high-speed lever head saw, a reheating furnace, a capillary high-pressure water descaling device, Twelve-rack two-roll reducer, rotary sizing machine, high-speed lever-type cutting Saw Saw, cooling bed, capillary weighing device, electrical control system, PLC Microcomputer automatic control system, liquid
