    Description: The present invention relates to the field of metal solidification and continuous casting, and in particular it relates to a two-roll continuous casting table corner rolling device with inclined
    Rollers.
    Defects due to straight cracks in edges or bends are common in plate and strip production technology in today's world. Particularly with the recent development of heavy plate production technologies, the expansion ratio of plates tends to increase, and defects due to straight cracks in edges or due to bending of the plates tend to be farther away from the edges of the plates and closer to the center , In order to meet the quality requirements, companies in the iron and steel industry have to cut away the defects described above by increasing the amount of edge cutting, which reduces the yield. This leads to a substantial increase in the production costs of the companies.
    As such, one technical measure used by those skilled in the metallurgy is to use chamfering technology, in addition to optimizing the quality of the molten steel, secondary cooling technology, and suitable rolling. Chamfer crystallizer technology with a chamfer side surface is commonly used in the prior art. Although the chamfering technology can effectively solve the problem of transverse corner cracks in a cast sheet, numerous results of manufacturing practices show that in the case of a continuous cast sheet made using the chamfering technology with the parameters described above, the angle of a chamfered corner , which is formed by a chamfered surface and an upper or lower wide side of the cast sheet, is relatively small, generally less than 135 °, defects due to straight cracks in edges or bends etc. of a plate or strip in a subsequent rolling process of the cast sheet cannot be completely removed in this form.
    Accordingly, some experts in metallurgy at home and abroad have developed methods for rolling corners of a cast sheet in order to obtain a continuous cast sheet with corners of a more suitable shape.
    For example, document CN204747439U discloses an apparatus for rolling a corner of a continuous cast sheet, the device being placed on the left and right sides of the cast sheet, i.e. that is, a chamfer roll with convex edges at the top and bottom ends is provided on each side of the cast plate, the chamfer roll with the convex edges rolling towards the cast plate with power and the corner of the cast plate being rolled from the convex edges of the roll to chamfer the corner of the cast sheet, further optimizing the shape of the corner to meet the requirement to remove defects due to straight cracks in edges or bends, etc. while rolling the wide side of moderately thick plates. In the actual manufacturing application, the chamfer roller with the convex edges rolls the corner of the cast sheet from a side by squeezing instead of rolling the corner of the cast sheet in a straight forward direction. This inevitably causes two problems: a large rolling pressure and a reduced roller life due to friction.
    In view of the above-mentioned shortcomings and disadvantages in the prior art, it is an object of the present invention to provide a two-roll continuous casting corner rolling device with inclined rolls.
    To achieve the above object, the present invention provides the following technical solution.
    The present invention provides a two-roll device with inclined rolls for rolling corners of a continuous casting table, which has chamfer rolls, a roll support frame, a connecting piece and a drive push rod, the roll support 1/8

    An angle α of 0 ° to 45 ° is formed between the roller spindle of the chamfering roller and the wide side of the continuous casting plate; and an angle β of 1 ° to 45 ° is formed between the roll surface of the chamfering roller and the wide side of the continuous cast plate or between an arc tangent at a contact point between the curved roller surface of the chamfering roller and the wide side of the continuous cast plate and the wide side of the continuous cast plate.

    [0019] In comparison with the prior art, the present invention has the following advantageous effects:
    The apparatus of the present invention is mounted on the left side and the right side of the continuous casting table, and while a continuous casting machine is pulling the table, a drive push rod of the two-roll continuous casting table corner rolling device with inclined rolls moves energy-driven towards the continuous casting table, and that Corner of the continuous cast sheet is rolling. Then, with the movement of the casting plate, the chamfering rolls continuously roll the corner of the continuous casting plate. The amount of rolling of the corner of the continuous casting plate by the chamfering roller is determined primarily by a driving force of the drive push rod. The greater the driving force, the greater the amount of rolling of the corner of the continuous cast sheet. In addition, due to the inclined shafts of the chamfering rollers 1 in combination with the inclined roller surfaces of the chamfering rollers, a good angle can be formed to roll the corner of the continuous cast sheet forward, and a required corner shape of the cast sheet can be obtained with a low rolling force. Furthermore, due to the reduced friction between the rollers and the continuous casting plate, the service life of the rollers is extended considerably.
    The apparatus of the present invention can roll the corner of the continuous cast 2/8
