Description

Swing roller device of square billet continuous casting machine

Technical Field

The invention relates to the technical field of oscillating rollers, in particular to an oscillating roller device of a square billet continuous casting machine.

Background

When the continuous casting machine is used for casting, a casting blank can be continuously pulled out of the tension leveler, the casting blank is cut into a fixed size for next procedure processing by using a flame cutting machine after entering a roller way, in the cutting process of the flame cutting machine, the cutting is completed in the process of synchronously advancing with the casting blank, a cutting gun passes through a swinging roller below in the cutting process, on one hand, the temperature of the casting blank is high when the casting blank is pulled fast, the casting blank possibly droops too much after being cut by fire, so that the casting blank cannot normally enter the conveying roller way, and even serious conditions can cause blank stagnation accidents. On the other hand, in order to avoid the cutting of the oscillating roller, the roller is swung down under the action of a hydraulic cylinder when a cutting gun reaches the roller, but cracks are easily generated on the surface of the oscillating roller due to the baking of steel slag and a casting blank generated by high-temperature cutting, so that the service life of the oscillating roller is very short, and is only 3 months on average.

When the flame cutting machine cuts a casting blank, the oscillating roller is lifted once, so that the casting blank is prevented from falling due to high temperature of the casting blank and different components and temperatures of various steels, the casting blank is ensured to smoothly enter a conveying roller way, and the blank stagnation accident is avoided.

When the steel components are different, the hardness of the casting blank is also changed, the lifting distance and time of the oscillating roller need to be strictly controlled, and if the hardness of the casting blank is higher, the lifting time point of the oscillating roller can be delayed; if the hardness of the casting blank is low, the casting blank needs to be lifted in advance, and then if the stress point of the oscillating roller on the casting blank can be adjusted in the lifting process, the casting blank can be better flattened.

Although the hardness of the casting blank is improved by fully cooling the casting blank by extending the tail end of the withdrawal and straightening unit under the condition of low hardness of the casting blank, the cutting difficulty and the cutting power consumption of the flame cutting machine are improved, and thermal stress cracks are generated at the cutting fracture.

The invention of the prior application number CN201811489227.1 discloses an oscillating roller device which is easy to maintain and can realize the function of collecting blanks on line.

Although the invention solves some problems, the following problems still exist when in use and need to be solved:

the swinging roller body is fixed at the right end of the input roller way, flexible adjustment cannot be carried out, and particularly in the continuous casting process facing different materials, a casting blank needs to be guided to the input roller way at an early or late time;

therefore, the applicant takes the experience of abundant design development and actual manufacturing in the related industry for years, researches and improves the existing structure and deficiency, and provides a swing roller device of a billet continuous casting machine so as to achieve the aim of higher practical value.
