Rolling mill capable of being used in vertical and horizontal rolling manners

Abstract

The invention discloses a rolling mill capable of being used in vertical and horizontal rolling manners. The rolling mill comprises a rack assembly and a roller assembly; the rack assembly comprises a square framework; the square framework is formed by detachably connecting two half frame racks through a connection piece; the roller assembly comprises a roller rack and two driving rollers arranged on the roller rack; and the roller rack is fixedly arranged in a square window of the square framework in a vertical arrangement manner of the driving rollers and a horizontal arrangement manner of the driving rollers. According to the rolling mill capable of being used in the vertical and horizontal rolling manners provided by the invention, the arrangement manners of the rollers can be converted; a vertical rolling process or a horizontal rolling process can be selected according to product requirements; the adaptability of the rolling mill is strong; the variety requirement of a production process can be met; the generality is good; the rolling quality and the yield of the rolling mill can be improved; the edges of the square framework are supported by fixing the roller assembly through the detachable square framework, so that the rigidity is large, the bearing effect is good, and the rolling requirement can be met; and meanwhile, the square framework can be opened, the rolling mill is used for conveniently replacing the rollers, and the maintenance working efficiency can be improved.

Description

technical field [0001] The invention relates to steel rolling equipment, in particular to a steel rolling mill. Background technique [0002] At present, hot-rolled H-beams and rails are generally rolled and produced by universal rolling mills. The horizontal rolls and vertical rolls of the universal rolling mill together form the cross-section of H-beams or rails. As described in the patent US5553475A, its cross-sectional shape is H The H-beam is rolled horizontally. In the rolling process, the upper and lower horizontal rolls are belt-driven driving rolls, the left and right vertical rolls are driven rolls, and the rolled intermediate blank is in an X shape. This kind of rolling mill with upper and lower horizontal rolls as driving rolls and left and right vertical rolls as driven rolls can be called a horizontal universal rolling mill. It is a universal rolling mill structure type that has been used in the production of section steel rolling. Its structure is as shown in...

Problems solved by technology

This kind of rolling mill with upper and lower horizontal rolls as driving rolls and left and right vertical rolls as driven rolls can be called a horizontal universal rolling mill. It is a universal rolling mill structure type that has been used in the production of section steel rolling. Its structure is as shown in patent ZL201110025614 .1 or ZL201110280861.6, the structure of this kind of horizontal universal rolling mill, because the horizontal roll can only be installed in the horizontal direction, driven by the power source as the active roll, therefore, only the horizontal rolling process can be used for production, resulting in When rolling H-shaped steel or steel rail, when the rolled piece enters the universal rolling mill for rolling, the cooling water of the roll will accumulate in the upper groove of the rolled piece, and the temperature of the part of the rolled piece in contact with the cooling water will drop rapidly, and the mechanical properties will deteriorate, resulting in a high yield. Low, uneven organizational performance and a series of problems

[0003] At the same time, the horizontal universal rolling mill in the prior art is a fixed horizontal rolling mode, which is a universal rolling mill that cannot be converted into vertical rolling, and the rolling method is relatively single and has poor adaptability
