Description

Technical Field

[0001] The utility model relates to the field of steel production devices, in particular to a rapid billet turning device for steel billets. Background Art

[0002] The continuous development and innovation of steel production technology has made remarkable achievements in increasing production capacity and reducing energy consumption. At present, the hot billets produced in the steelmaking workshop are directly delivered to the rolling mill through the conveyor roller, which greatly improves the temperature of the billets entering the heating furnace and effectively reduces the gas consumption required for heating the rolling mill, making a positive contribution to the sustainable development of the steel industry.

[0003] However, during the process of lifting or conveying hot billets, the cold air causes the temperature of the outer surface of the billet to drop, resulting in a large shrinkage of the outer billet. This phenomenon is mainly caused by the environmental conditions during the conveying process, especially the influence of the cold air, which causes the billet to be subjected to uneven temperature distribution during the conveying process. Due to the difference in temperature between the inside and outside of the billet, the shrinkage of the inside and outside is not synchronized, and finally the billet bends to the side with a larger temperature drop. This bending not only affects the quality of the billet, but also creates additional load on the equipment during the conveying process.

[0004] In addition, bent steel billets are prone to hit conveyor rollers or guard plates, which increases equipment wear, reduces equipment service life, and also increases equipment failure rate. In order to solve this problem, steel production companies need to carry out technological innovation and improvement based on existing equipment to ensure that the efficiency of steel billets entering the furnace is greatly improved and the impact of bending is reduced.

The utility model can achieve the purpose of rapidly turning the direction of the steel billet by driving the eccentric hook 4 through the cylinder 3, while ensuring that the cast billet is not suspended from the production line, thereby greatly improving the efficiency of the bent steel billet entering the furnace, and preventing the shutdown or equipment damage caused by the conveying roller or guard plate on the top of the bent steel billet.
