Abstract
The utility model relates to a working roller way frame of a blooming mill, which comprises a roller way bearing block and a casting frame body and is characterized in that: the casting frame body is provided with a groove at the installation position of the roller way bearing block, the width size of the groove is matched with the shape size of the roller way bearing block, and the depth of the groove is 20 to 150 millimeters. Compared with the prior art, the working roller way frame of the blooming mill has the advantages that: the groove structure can effectively relieve a shearing force produced by impacting a roller way through billets on foundation bolts of the roller way bearing block, and the shearing force is mainly borne by the casting frame body, so the foundation bolts of the bearing block are prevented from being sheared and broken; and the working roller way frame has a simple structure, is convenient to process, and is favorable for reducing equipment failure rate.
Description
Technical field
The utility model relates to a kind of work roll table frame behind the machine before the blooming mill machine that is applicable to.
Background technology
In the steel rolling production process, because steel billet frequently clashes into work roll table, make the roller bed bearing seat foundation bolt bear very big shearing force, because long-term excess load is stressed, cause the easy fatigue break of foundation bolt, especially in work roll table zone, blooming mill front and back, because steel billet moves back and forth, unit mass is big, and speed is very fast relatively, and impulsive force is big and frequent, make that the work roll table roller axle bearing foundation bolt phenomenon that fractures is extremely serious, not only influence the quality and the output of product, and cause equipment and security incident easily, must draw attention.
Summary of the invention
The purpose of this utility model provides a kind of blooming mill work roll table frame, prevents in the rolling process that the work roll table bearing block foundation bolt accident that fractures reduces equipment failure rate.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of blooming mill work roll table frame comprises roller bed bearing seat, casting support body, is provided with groove in the roller bed bearing seat installation place on the casting support body, and the overall dimensions of recess width size and roller bed bearing seat are complementary, the dark 20～150mm of groove.
Compared with prior art, the utility model has the advantages that: groove structure can effectively be alleviated the shearing force to the roller bed bearing seat foundation bolt that steel billet bump roller-way causes, shearing force is mainly born by the casting support body, the generation of having avoided the bearing block foundation bolt to shear the phenomenon that fractures, simple in structure, easy to process, favourable reduction equipment failure rate.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is a kind of blooming mill work roll table of the utility model frame example structure schematic diagram, comprise roller bed bearing seat 2, casting support body 1, working roll 4, be provided with groove 3 in roller bed bearing seat 2 installation places on the casting support body 1, the overall dimensions of groove 3 width dimensions and roller bed bearing seat 2 are complementary, and form matched in clearance between the roller bed bearing seat 2, fit clearance is less than 1mm, the dark 20～150mm of groove.Roller bed bearing seat 2 is arranged in the groove 3 by foundation bolt 5, groove structure can effectively be alleviated the shearing force to roller bed bearing seat foundation bolt 5 that steel billet bump working roll 4 causes, shearing force is born by foundation bolt 5 and casting support body 1 respectively, effectively solve the problem that foot bolt fractures, guaranteed the normal operation of equipment.
