Continuous straightening machine with slide plate guide and vertical pressing

Abstract

The invention relates to a continuous straightening machine with slide plate guide and vertical pressing and belongs to the technical field of steelmaking and continuous casting equipment of a metallurgical industry. According to the technical scheme, a straightening rack (6) is provided with a straightening cylinder bracket (1) and a guide frame (19); the straightening cylinder bracket (1) is provided with a straightening cylinder (2); the straightening cylinder (2) is connected with the guide frame (19); the straightening rack (6) is internally provided with an upper roller (7) and a lower roller (8); two ends of the upper roller (7) are fixed on the guide frame (19) of the straightening rack (6) through an upper bearing seat (15) respectively; the upper bearing seat (15) is provided with a guide sliding plate (12); the straightening rack (6) is provided with a guide rail plate (13) matched with the guide sliding plate (12). The continuous straightening machine provided by the invention has the beneficial effects that a greater straightening force can be provided and the straightening of a casting blank and the improvement of the quality of the casting blank are facilitated; thestraightening stress and strain of a blank shell can be minimum and the requirements of straightening a strip liquid ore are met.

Description

technical field [0001] The invention relates to a continuous straightening machine with sliding plate guide vertical pressing, and belongs to the technical field of steelmaking and continuous casting equipment in the metallurgical industry. Background technique [0002] The continuous casting machine is an important metallurgical equipment in the steelmaking plant, and the casting machine and the straightening machine are the core equipment of the continuous casting machine. After the steel drawing command is issued, the billet drawing machine pulls the billet out of the crystallizer through the dummy rod, and when the joint between the head of the dummy rod and the head of the billet passes under the straightening roller of the straightening machine, the straightening roller Press down under the action of the straightening cylinder to disengage the casting slab from the dummy rod, and at the same time, the straightening machine straightens the casting slab.

Problems solved by technology

[0006] (3) The driving mechanism of the straightening machine is installed on one side of the straightening roller. The transmission device has a large weight and is far away from the slab, and the size of the slab is small. In this way, the transmission device will bring an additional bias to the straightening roller. Load moment, this eccentric load moment acts on the slab through the straightening roller, causing the straightening upper roller and the straightening lower roller to be non-parallel, the surface dimension of the slab is deformed, and the slab deviates

[0007] (4) With the advancement of continuous casting machine efficiency, the liquid core of the cast slab must be very long. If the above-mentioned straightening is still used, the radius of the continuous casting machine will inevitably be large, which is obviously unreasonable;
