国内第一台国产变截面板簧轧机于1990年3月4日在南京钢铁厂热轧成功,4月23日由冶金部主持通过变截面板簧轧机竣工交接仪式并顺利进入试生产阶段。变截面板簧轧机以本厂自产的28MnSiB 为坯料,先后轧制了TE—30、NT—3~#及 NT—5~#等板弹簧共1937件,合格率达96～99%。BJMH—Ⅰ型轧机技术性能:1.轧机型式:四辊轧机。2.设计能力:3000t/a。3.产品规格:最
The first domestically produced variable section leaf spring mill was successfully rolled in Nanjing Steel Plant on March 4, 1990. On April 23, the Ministry of Metallurgical Affairs completed the handover ceremony through the variable section leaf spring mill and successfully entered the trial production stage. The variable cross-section leaf spring mill, with its own 28MnSiB as its raw material, rolled a total of 1937 TE-30, NT-3 and NT-5 plate springs with a pass rate of 96-99%. BJMH-Ⅰ-type rolling mill technical performance: 1. Rolling mill type: four-high mill. 2. Design capacity: 3000t / a. 3. Product Specifications: Most
