Embodiment Construction

[0042] The present invention will be further described below in conjunction with embodiments.

[0043] A two-roll continuous casting billet cornering device with inclined rollers of the present invention includes a chamfering roller 1, a roller shaft 2, a roller support frame 3, a connecting piece 4 and a driving push rod 5. The roll support frame 3 is connected to a drive push rod 5 that can move forward and backward. The two cantilever ends of the roll support frame 3 are respectively provided with a chamfering roll 1; the two chamfering rolls 1 are arranged symmetrically, and the chamfering roll 1 The roll surface is at an oblique angle with the wide surface of the cast slab;

[0044] The device is installed on the left and right sides of the continuous casting slab 6 to continuously roll the corners of the continuous casting slab 6.

[0045] The two chamfered rolls 1 on the two cantilever ends of the roll support frame 3 can be arranged symmetrically or asymmetrically.

Abstract

The invention relates to the field of metal solidifying and continuous casting, in particular to a two-roller continuous casting slab angle rolling device with inclined rollers. The device comprises chamfering rollers (1), a roller supporting frame (3), a connecting part (4) and a drive push rod (5); the roller supporting frame (3) is connected with the drive push rod (5) capable of moving in a front-and-back manner, and the two cantilever ends of the roller supporting frame (3) are each provided with one chamfering roller (1); the two chamfering rollers (1) are oppositely arranged, and inclined angles are formed between roller faces of the chamfering rollers (1) and the wide face of a casting slab; and the device is arranged on the left side and the right side of the continuous casting slab (6), and continuously rolls the angle of the continuous casting slab (6). The device can achieve positive rolling of the angle of the continuous casting slab, and therefore the beneficial effects of being small in rolling resistance, easy to maintain and the like are achieved.

Description

Technical field [0001] The invention relates to the field of metal solidification and continuous casting, in particular to a two-roll continuous casting billet angle rolling device with inclined rolls. Background technique [0002] In the modern world of plate and strip production technology, the defects of straight edge cracking or peeling are common, especially with the development of medium and heavy plate production technology recently, the stretch ratio of the plate is increasing, and the straight crack or peeling of the plate edge The defects are also farther away from the edges of the board and closer to the center. Iron and steel companies have to increase the amount of trimming and reduce the yield to remove the above-mentioned defects and meet the quality requirements. This has caused a substantial increase in the production costs of enterprises. [0003] To this end, in addition to optimizing the quality of molten steel, secondary cooling technology, and reasonable rol...
