The Research Of Cutting Parameter And Process Optimization To High Chromium Back-up Roll

Back-up roller studied in the paper is a kind of specifc product for the rolling steel equipment ,based on mechanical manufacture , material ,machinery power-generating control, management technology. The paper detailedly introduces research, manufacture and the use process .The main content and achievements of research list as fellow:Back-up roll is a kind of specific and key product designed for the rolling steel equipment ,Back-up roll studied in the paper is applied to support the roll for stability rolling,the quality of Back-up roll will affect quality of rolling product and life of roller. The research based on high efficiency and combined machinery and power-generating technology, optimize process technology.through a lot of cutting test ,we optimize a series specifc cutting tool and auxiliary .we set up the hardware of "Back-up roll produce line",meanwhile we take something seriously to improving quality of staff ,we have realized batch ,specifc and numerical control produce on the Back-up roll step by step .①This thesis bring forth new ideas: The paper has choosen basing on material .we have optimized cutting parameter by a lot of test .It have an effect in the manufacture, Advance cutting tool have high efficiency more than hard alloy. In addition high accurate equipment , high quality operator , reasonable process technology and scientific management made specifc and numerical control produce on the Back-up roll getting into a good environment. It becomes the best property of erzhong group.②This thesis brings original ideas: the paper combined beneficial and overcome .It overcome lathe problem when the hard of material is HS 70～75. It realized the best benefit. The leader of wok shop works out some management rule about using advance cutting tool. And checks cost regular.have a good income.③This thesis brings practical ideas: The paper originate produce site of The Fourth Work Shop, Technology and cutting tool have been optimized again and again. They can meet the need of batch ,specifc and numerical control produce on the Back-up roller .optimized technology and advance cutting tool have promote efficiency more than twenty-five percent. There are no any substandard products . A lot of back-up roll have been conveied to consumer,effects is very well.quality have got to the requirement of GP,JSW and so on ,this kind of product can replace input products ,our products have been accepted of consumer,including VAP and BOASHAN steel .Especially huge Back-up roll has been researched ,it ended the fact that we must input this kind of product for other country before.we have got lots of orders,and have a good foreground.
