Roughing Rolling Works is required by Seamless Steel Works of Baoshan Complex to provide billets with weight tolerances not exceeding+1% and diameter deviations less than+ 1mm. For this reason, PLC is used in Roughing Rolling Works to control pushing and stretching forces of rolling on 6VH mandrel mill with the result of slight pushiag and stretching rolling obtained, therefore billets with various steel grades and with satisfied deviations of weight and diameter over full length can...

Roughing Rolling Works is required by Seamless Steel Works of Baoshan Complex to provide billets with weight tolerances not exceeding+1% and diameter deviations less than+ 1mm. For this reason, PLC is used in Roughing Rolling Works to control pushing and stretching forces of rolling on 6VH mandrel mill with the result of slight pushiag and stretching rolling obtained, therefore billets with various steel grades and with satisfied deviations of weight and diameter over full length can be Produced.

宝钢无缝钢管厂要求初轧厂提供的管坯重量公差在±1%之内,全长直径偏差不超过±1mm。为此,初轧厂采用PLC对6VH连轧机进行推力、张力轧制控制,实现了微张力或微推力轧制,生产出重量和全长直径偏差都满足要求的不同钢种的管坯。

30m-long mandrel is the basic tool for 140mm mandrel mill in Baoshan. The development of the mandrel blank is described including heating, roughing rolling, continuous rolling, cooling, annealing and handling of the steel for the blank. The inspecting result shows that the quality and life of the newly-developed mandrel blank are as the same as thai of the imported one.

30m长芯棒是宝钢寸φ140mm连轧管机组的主要工具。介绍了该芯棒坯的研制情况,包括芯棒钢的装炉、初轧、连轧、锯切、冷却退火及吊装运输等。检验结果表明,研制的芯棒坯质量和寿命与进口芯棒坯相当。

A complex test about the parameters of technique and equipment has performed on roughing roll stands R_2 & R_4 of hot strip mill in WISCO.The rearch of it consists of the relationship between actual motion of rolls and axial forces of rolls on 4H-mills,the forming origins and values of axial forces.Depending on the test data,the actual loading,the mechanism of fracture and the working life of thrust bearing using for back up roll are explored,at the same time,some available steps are suggested to reduce the break of thrust bearings using for back up rolls on stands R_2& R_4.

通过对武汉钢铁公司热轧带钢厂粗轧机(R2~R4)设备、工艺参数的综合测试研究,论述了四辊轧机辊系运动状态与辊系轴向力的关系,分析了辊系轴向力生成的原因和轴向力的大小。以实测数据为依据,讨论了支承辊止推轴承的实际负荷状况、破坏机理及工作寿命,提出了减少R2~R4轧机支承辊止推轴承烧损的可行措施。
