Steel Rolling Mill Machines Manufacturer in China Fujian

Jinquan manufactures kinds of rolling mill machines, like universal mills, short stress mill/housingless mill, two high rolling mill machines, three high rolling mill machines, etc..

The advantages of the short-stress rolling mill are: (1) The high rigidity of the short-stress rolling mill ensures the high precision of the product and is easy to realize negative deviation rolling. (2) Symmetrical adjustment can be achieved. This is of great significance for stable operation, increasing productivity, saving time for maintenance and replacement of the guide shield beam, reducing operation accidents, avoiding process accidents (such as rolling elbows, impact and roll paper) and extending the service life of the guide shield. (3) Because the short-stress rolling mill changes the force transmission path and reduces the concentrated load of the screw to the distributed load dispersed on both sides of the bearing housing, the bearing and the bearing housing bear better stress and are twice the life of the bearing , More than half of the ordinary short-stress rolling mill, thereby reducing product costs. (4) The roll system of this type of short-stress rolling mill is pre-installed and adjusted before the roll is changed, and the new roll system can be replaced about ten minutes after shutdown. After the adjusted new roll system rolls a kind of steel, the product can be qualified. Therefore, the short-stress rolling mill has good pre-adjustment performance, quick roll change and high yield.
Generally, there are two ways to shorten the return line of the short-stress rolling mill: 1 is to change the load-bearing structure of the short-stress rolling mill, that is, to reduce the number of load-bearing parts in the rolling mill. The frame shortens the stress return by shortening the length of the compressed parts. 2 is to change the force transmission path, for example, the rolling force does not directly act on the top of the arched window, but acts on the column near the short-stress rolling mill, thereby shortening the stress return line.
