Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of straightening equipment of a bloom continuous casting machine, and particularly relates to a straightening device for a bloom continuous casting machine. BACKGROUND

[0002] At present, the bloom continuous casting machine is an indispensable equipment in modern steel production and is widely used in continuous casting processes. It can efficiently convert high-temperature molten steel into semi-finished products with certain shapes and sizes, such as blooms, billets, etc. With the progress of metallurgical technology, the design of the continuous casting machine is continuously optimized to improve the quality of the products, production efficiency, while reducing energy consumption and maintenance costs. The straightening device, as one of the key components of the continuous casting machine, directly affects the quality of the final product and the overall stability of the production line.

[0003] At present, in the straightening process of the bloom continuous casting machine, there are various common solutions. One method is to use fixed straightening roller groups, which fix the positions of the straightening rollers through pre-set mechanical structures to ensure that the bloom is corrected within a specific path. Another method is to use an electric drive mechanism to adjust the position of the straightening roller, which drives the gear or bidirectional screw through the motor to realize the change of the height of the straightening roller. In addition, there is also a gas pressure driven way, that is, the straightening roller is pushed to move by the gas cylinder to achieve the adjustment purpose. These solutions have their own characteristics and are suitable for different application scenarios.

[0004] However, these existing methods still have some significant defects in actual application. The fixed position straightening roller group cannot be flexibly adjusted and is difficult to deal with blooms of different specifications and temperature conditions, resulting in unstable straightening effect. Although the electric drive mechanism can adjust the position of the straightening roller, the response speed is slow and cannot timely adapt to changes in the production process, thereby affecting the straightening precision. The gas pressure driven way is prone to cause uneven stress on the bloom during the straightening process due to the instability and volatility of the gas source, further affecting the product quality.
