China's first new six-roller reversible cold rolling unit, which was developed by China National Heavy Industry Research and Development Institute and completed with double-equipment manufacturing, successfully performed a thermal load test at a customer site. The successful development of this new high-precision compact six-high rolling mill has broken foreign monopolies, filled domestic gaps, and made positive contributions to the localization of major technical equipment manufacturing.
This set of 500mm single-stand six-roller reversible cold-rolling unit is the core and key equipment in Dongyang Hengye Steel Belt Co., Ltd. in order to achieve product upgrading and upgrade to meet the demand of high-end orders. Mainly used in the production of excellent special steel. Products are widely used in imported wiper support frames, high-performance leaf springs and other metal materials.
In order to meet the needs of users, China Heavy Industry Institute and Double Equipment jointly work together to carry out special research through joint advantages, and develop, design, and manufacture this six-roller reversible cooling with the most advanced domestic technology of the same type, the highest precision and the most difficult manufacturing. Rolling mill. It not only enriches the types of cold-rolled strip mills, but also provides support for new technologies and further development, improvement and improvement of new strip rolling equipment.
It is particularly worth mentioning that during the development process, the R & D and manufacturing team did a lot of innovative work in response to the characteristics of the unit's large deformation resistance and large product thickness span, and achieved the goal of wide rolling mill thickness span and strong rolling force. Product plate shape, roll shape and surface quality are excellent.
