The Installation Technical Research And Application Of Ultra-large Split Type Rolling-mill Housing

The iron and steel field have integration constantly along with the national economy developed at a full speed.This requires the manufacture enterprise continually to improve the output,standard and the type of the product,the production line equipment was developed accordingly,so there are more and more milling line of wide and thick plate,the ultra-large type housing is grow up on and on.In the other side,all kinds of pressing machine in the equipment manufacture field was produced become larger and larger,the frame housing of them is much bigger than the mill housing,the market field of them also will be more wide.During the installation process of ultra-large housing,the lifting operation of the large equipment is inadequacy by the reason of limited field and space.In order to reduce the impact to the foundation construction during the work and ensure the construction progress on the rails,at the same time to save the construction cost and reduce the wasting of resources.In this text we take the installation progress of split housing in one wide thick plate project for example to explain the overall process from unload to lift in the right position after the split housing arrived at the site.The machining and cutting problems of big diameter connecting bolt M350 for the ultra-large split type rolling mill housing.The work is finished that retrofitted existing equipment and completed the complete removal of the connecting bolt..Design and arrange the assemble platform of housing to design the housing assemble platform and translation turnover device through the computer simulation technology.The problem for the whole ultra-large rolling mill housing cannot be lifted in the right position by the crane after assembled.We finish the overall lifting progress of ultra-large split housing include unload,assemble,translation(cross the span)and turnover in the right position through the existing crane in the construction site.Finally we make a summative statement for the supporting measures of security,quality and environment during the construction progress of housing,expound that the finished technical research will have the important function for the enterprise in the construction progress in future.
