Claims

[Scope of utility model registration request]

In the universal stand for rolling H type steel,
Seats are provided on the upper and lower surfaces of left and right vertical roll axle boxes that can be raised and lowered, and seats are provided on the upper and lower surfaces of the lower horizontal roll boxes that have wheels on their lower surfaces and can move on rails and can be raised and lowered. Providing seats that are equally spaced from the lower seats and at different phases with respect to the rolling center line,
The roll changing device is further characterized in that seats are provided on the lower surfaces of the left and right shaft boxes of the upper horizontal roll that can be raised and lowered, respectively, at equal intervals from the upper seats of the vertical roll shaft box and at different phases with respect to the rolling center line.
