Casting blank built-in before-cutting roller bed

Abstract

The invention relates to a casting blank built-in before-cutting roller bed, and belongs to the technical field of continuous casting equipment in the metallurgical industry. According to the technical scheme, integral through rollers (3) are of a hollow structure, and the two ends of each integral through roller (3) are arranged on bearing seats correspondingly; metal hoses which are cooled afterwater injection are arranged between the bearing seats; protective covers (5) are arranged on the bearing seats; motors (9) are in driving connection with the integral through rollers (3) through speed reducers (7); the two ends of each integral through roller (3) are provided with a water feeding rotation connector (1) and a water discharging rotation connector (8) which communicate with the interior of the integral through roller (3) correspondingly; the positions, corresponding to the two sides of each current of a continuous casting machine, of a plurality of before-cutting rollers arranged in parallel are provided with water cooling plates (11) correspondingly; and the water cooling plates (11) are long-strip-shaped guide plates and provided with water troughs. The casting blank built-in before-cutting roller bed has the beneficial effects that the self weight is decreased, the rigidity of the before-cutting rollers is improved, and the situation that creep deformation and down-warping are conducted on the steel structures of the before-cutting rollers at the high temperature can be avoided.

Description

technical field [0001] The invention relates to a slab built-in pre-cutting roller table, which belongs to the technical field of continuous casting equipment in the metallurgical industry. Background technique [0002] The continuous casting front cutting roller table is located between the drawing and leveling machine and the cutting area of ​​the continuous casting machine. The billet is an important equipment that enters the cutting area for cutting to length. When the continuous casting machine starts casting, the post operator must stand on the roller table before cutting to monitor the drawing of the dummy bar. As well as the deviation of the head billet after stripping, it must be dealt with in time. [0003] At present, there are two forms of roller table before cutting: one is the form of several short rolls for each stream of the continuous casting machine, and the other is the form of integral through rolls with several streams connected together. The common dis...

Problems solved by technology

[0003] At present, there are two forms of roller table before cutting: one is the form of several short rolls for each stream of the continuous casting machine, and the other is the form of integral through rolls with several streams connected together. The common disadvantages of these two forms Yes, the rollers are on the roller table, the billet hangs on the roller table, so the temperature around the roller table before cutting is high, and only the hoop acts as a guide on the roller table, which is not conducive to the processing of the first billet at the beginning of the continuous casting machine production accident

If a certain flow of the continuous casting machine fails to start pouring, when a certain flow slab starts pouring in the middle of monitoring, it is not conducive for the post operator to deal with the production accident of casting

In addition, several streams are driven by an integral through-roller, and when the through-shaft ground roll is used, the failure rate of the equipment will be increased correspondingly due to the high-temperature and high-humidity environment of the ground roll, and the amount of equipment maintenance will be increased.
