SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a front and back guide of roughing mill setting, and a front and back guide of roughing mill setting solves the roughing and rolls out the roll surface width at rolling in-process middle base, and the unstable problem of board type, effectual correction roughing camber, S are bent, have improved roughing plate shape quality, have improved the operating efficiency.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a front and back guide for a roughing mill comprises a base and a framework arranged on the base, wherein a framework main body is a plurality of longitudinal beams which are arranged in parallel, a plurality of cross beams for supporting and fixing are arranged below the longitudinal beams, and baffles with equal height are arranged on two sides of the framework main body in parallel; the device also comprises a rough rolling guide plate I and a rough rolling guide plate II which are hinged with each other at the inlet and the outlet of the rough rolling mill and are arranged at the front edge of the framework; and a first guide block and a second guide block which are hinged and fixed together through bolts are symmetrically arranged at two sides of the joint of the rough rolling guide plate I and the framework.
The utility model discloses technical scheme's further improvement lies in: the first guide block and the second guide block are arc-shaped baffles which are deviated from the inner side of the framework.
The utility model discloses technical scheme's further improvement lies in: two through holes are arranged on the second guide block.
Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
the utility model provides a front and back guide of roughing mill setting has stabilized the roughing board type, even the not good condition of roughing board type has appeared, can not appear the roller phenomenon yet, has stopped the possibility of going out the roller, has reduced the hidden danger of roughing scrap steel, has improved production quality, has brought direct economic benefits.
The utility model provides a around the roughing mill setting lead and defend, no longer need take the leader board wholly out during roll change, only need adjust II angles of the roughing leader board of roughing mill entry and just can realize the roll change, labour saving and time saving has alleviateed operating strength, has improved labor efficiency. Front and back guide for roughing mill
The utility model provides a lead around roughing mill sets up and defend, two through-holes that set up on the second guide piece, the fixed second of being convenient for is led and is defended the piece, realizes that the second leads the opening angle of defending the piece adjustable and firm.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
According to the attached figure 1 the utility model provides a front and back guide's of roughing mill setting overlook the structure sketch map, the attached figure 2 is shown the utility model provides a front and back guide's of roughing mill setting overlook the structure sketch map and the attached figure 3 is shown the utility model provides a front and back guide's of roughing mill setting rolls side-looking the structure sketch map is shown, the utility model provides a front and back guide of roughing mill setting, including base and the skeleton that sets up on the base, the skeleton main part is several longerons of arranging in parallel, is provided with several under the longeron and holds in the palm the crossbeam of fixing usefulness, and the both sides of skeleton main part are provided with the baffle of height in parallel; the device also comprises a rough rolling guide plate I1 and a rough rolling guide plate II 2 which are hinged with each other at the inlet and the outlet of the rough rolling mill and are arranged at the front edge of the framework; the two sides of the joint of the rough rolling guide plate I1 and the framework are symmetrically provided with a first guide block 3 and a second guide block 4 which are hinged and fixed together through bolts.
Specifically, rough rolling dummy block I1 and rough rolling dummy block II 2 are articulated each other, and angle about rough rolling dummy block II 2 can be adjusted at any time, realizes improving the rough rolling mill access & exit dummy block for fixed block (rough rolling dummy block I) and adjustment (rough rolling dummy block II), and the roll change need not pull out the dummy block wholly, only needs adjustment dummy block 2 angle upwards, just can realize changing the roll, saves time and laborsaving.
Further, according to figure 4 shown the utility model provides a pair of around roughing mill set up lead the first block's of defending structural schematic diagram and figure 5 shown the utility model provides a pair of around roughing mill set up lead the second of defending lead the structural schematic diagram of defending the block, first lead defend block 3 and second lead defend block 4 and be the inboard cowl of erroneous tendency skeleton. First guide block 3 can be under the cooperation of articulated bolt with, its inclination on the draw plate platform of quick adjustment to satisfy the needs that rough rolling operation goes out the roller and transports the roller.
Further, two through holes are formed in the second guide block 4, so that the opening angle of the second guide block 4 can be adjusted and fixed through the transverse bolts.
Specifically, when the steel is rolled by the roughing mill, and the steel head deviates to the operation side or the transmission side, the steel head is corrected by the jamming of the first guide block 3 and the second guide block 4 respectively, so that the steel head is kept straight. Meanwhile, the whole middle billet is limited by the guide blocks on the two sides, so that the offset is reduced, the whole middle billet is good in shape, a foundation is provided for finish rolling, and the rolling waste accidents caused by the problems of deviation, large steel head oblique angle and the like are effectively reduced.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
