Abstract
It the utility model is related to steel rolling apparatus field, more particularly to a kind of steel billet machine is driven for square steel rolling, including multiple box rolls being sequentially connected, box-section strut is provided with box roll, lug boss is provided among the upside and downside of at least one box-section strut.Steel billet machine is driven in the square steel rolling that the utility model offer can improve square steel internal soundness.
Description
Technical field
Square steel rolling equipment field is the utility model is related to, steel billet machine is driven for square steel rolling more particularly to a kind of.
Background technology
The rolling of high-quality square steel drives steel billet machine usually using box pass system.Steel billet machine is driven to roll including multiple boxes
Roller, a box roll include the roll body being oppositely arranged up and down, got on the bus out as required along body of roll circumference on roll body
Groove is referred to as groove, and the space that the groove on the top and bottom rolls body body of roll is formed is referred to as box-section strut.At present, improve in high-quality square steel
The method of portion's quality mainly has：(1) strand (raw material) specification, i.e. increasing compression ratio are increased；(2) power of stand motor is increased,
So as to increase single pass rolling reduction.Both the above method is to change strand (raw material) or increasing the power realization of stand motor
Improve high-quality square steel internal soundness, it is impossible to which realization improvement is high-quality in the case where casting blank specification is certain, stand motor power is certain
Square steel internal soundness.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of square steel rolling that can improve square steel internal soundness
Drive steel billet machine.
The utility model solves to drive steel billet machine for square steel rolling used by its technical problem, including multiple connects successively
The box roll connect, box-section strut is provided with box roll, is provided among the upside and downside of at least one box-section strut convex
The portion of rising.
It is further that lug boss is integrally formed with box roll.
It is further that the top of lug boss is connected by arc transition.
It is further that the depth of each box-section strut differs.
Being further that the upside and downside of at least one box-section strut are most middle is provided with lug boss.
It is further that the depth of box-section strut is at least 260mm, and the height of lug boss is between 20-50mm.
It is further that the depth of box-section strut is 360mm, and the height of lug boss is 35mm.
It is further that the surrounding of box-section strut is connected by arc transition.
The beneficial effects of the utility model are：Projection is provided among the upside of at least one box-section strut and downside
Portion, by setting lug boss to increase the single pass rolling reduction of the box-section strut, rolling deformation can go deep into steel billet center portion, be advantageous to
Improve steel billet center porosity, so as in the case where casting blank specification is certain, stand motor power is certain, improve the side of rolling out
Steel internal soundness.
Brief description of the drawings
Fig. 1 is that one kind drives steel billet machine with roller implementation schematic diagram；
Parts, position and numbering in figure：Box-section strut 1, lug boss 2.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model drives steel billet machine for square steel rolling, including multiple boxes being sequentially connected are rolled
Roller, box-section strut 1 is provided with box roll, lug boss 2 is provided among the upside and downside of at least one box-section strut.Fig. 1
Middle to be provided with lug boss 2 by the upside of second box-section strut 1 and downside are most middle, when square steel rolls, lug boss 2 can increase
The single pass rolling reduction of the box-section strut 1, rolling deformation can go deep into steel billet center portion, be advantageous to improve steel billet center porosity, so that
In the case that casting blank specification is certain, stand motor power is certain, the steel internal soundness for the side of rolling out is improved.
Specifically, processing for convenience and improving using effect, lug boss 2 is integrally formed with box roll, lug boss 2
Top is connected by arc transition.
Steel billet machine is driven when rolling square steel, from strand to the box-section strut needed finished product square steel by multiple different depth
1 rolling, so, the depth of each box-section strut 1 differs.And the surrounding of box-section strut 1 is connected by arc transition, is so set
Blank (supplied materials for arriving tandem rolling) upper and lower surface band projection circular arc that rolling is completed is put, the broadening that can reduce the vertical car of finished product becomes
Shape.
The utility model is less for specification due to being provided with lug boss 2 among the upside of box-section strut 1 and downside
Square steel, the depth of box-section strut 1 is not natively high, causes the height of the lug boss 2 of setting not high, the raising to square steel internal soundness
It is smaller.By being drawn in lot of experiments and practice, the depth of box-section strut is at least 260mm, the height of lug boss 20-50mm it
Between, or finished product square steel size in more than 150x150mm, so set effect preferable.Such as one embodiment：It is by size
360 × 450mm strands are rolled into 250 × 250mm axle steels, are provided among the upside and downside of second box-section strut 1 convex
Portion 2 is played, the height of lug boss 2 is 35mm.
