Abstract
A housingless beam mill stand is described in which horizontal rolls are mounted in chocks which are prestressed against a rectangular frame by tension bolts which pass through the chocks and the frame, in conjunction with the prestressing cylinder. Vertical rolls are carried by roll chocks which have clearance ways through which the tension bolts also pass, and which permit lateral adjustment of the vertical roll chocks and thus the vertical rolls.
Claims10
A housingless beam mill stand comprising:
- a frame of substantially rectangular form and including a central space defined by the frame, upper and lower chocks for upper and lower horizontal rolls located on opposite sides of the frame;
- roll gap adjustment means mounted in or on the frame, said roll gap adjustment means being infinitely variable between defined limits and acting effectively between the frame and the horizontal roll chocks;
- prestressing tension bolts acting between upper and lower horizontal roll chocks and passing through the space defined by the frame, whereby the adjustment means are preloaded;
- a pair of cooperating and opposed vertical rolls;
- and two chocks in which the respective vertical rolls are journalled, said vertical roll chocks being adjustably mounted on the frame to permit variation of the vertical roll gap, and having through passages elongated in one direction, said tension bolts passing through said passages while permitting adjustment movement of the vertical roll chocks lengthwise of the frame.
A beam mill stand as claimed in claim 4 wherein the adjustment mechanisms for the upper and lower horizontal roll chocks are coupled to synchronizing shafts displaced from the pass-line by a gear train for each adjustment mechanism.
