High-efficiency and energy-saving rolled steel production device

Abstract

The invention relates to a high-efficiency and energy-saving rolled steel production device. When high-temperature steel blanks are sent to a heating furnace discharging carrier roller set, the steelblanks can be conveyed towards the rear end to reach the tail end along the heating furnace discharging carrier roller set, lifting brackets lift the steel blanks and jack the steel blanks up, the steel blanks can roll on an inclined roller bed along the tops of the lifting brackets, then the steel blanks fall on a lower rolling mill feeding carrier roller set from the inclined roller bed, and therefore transferring of the steel blanks is automatically achieved; rolled steel heated on the roller bed enters cases from feeding ports in the right sides of roller sets, the hot rolled steel conveyed by the roller sets enters cold water to be rapidly cooled, and the rolled steel obtained before the rolled steel enters the cold water and after the rolled steel enters the cold water is cooled through air blown by air blowers; and lubricating oil used by the rolling mill is collected through lubricating oil collecting devices and is led into a lubricating oil station, when the temperature and the water content exceed the standard, the lubricating oil containing water enters an oil-water separator, water is separated, then the lubricating oil enters the lubricating oil station for standby use, the lubricating effect of the rolling mill is ensured, and the quality of the lubricating oil does not need to be manually observed frequently.

Description

technical field [0001] The invention relates to the technical field of steel rolling transportation equipment, in particular to high-efficiency and energy-saving steel rolling production equipment. Background technique [0002] The steel billet from the steel mill is only a semi-finished product, and it must be rolled in a steel rolling mill before it can become a qualified product. The continuous casting slab sent from the steelmaking plant first enters the heating furnace, then repeatedly rolled by the pre-rolling mill, and then enters the finishing mill. Steel rolling belongs to metal pressure processing. In the hot rolling production line, the steel billet is heated and softened, and is sent to the rolling mill by the roller table, and finally rolled into the size required by the user. [0003] During the steel rolling process, the billet needs to be heated in a heating furnace first, and then the high-temperature billet is sent to a multi-pass rolling mill for rolling ...

AI Technical Summary

Problems solved by technology

However, the ordinary transfer roller table cannot control the time of changing lanes during transfer, and the steel billet is automatically rolled onto the rollers of the rolling mill, which is easy to cause collision and wear between the steel billets, which affects the quality of the product; in addition, the rolling table needs to be transported to Cooling treatment is carried out inside the designated equipment, during which switching, feeding and reclaiming are required to slow down the heat treatment speed of rolled steel; if the rolled steel after heat treatment can be directly transported on the roller table and undergo rapid cooling treatment, the production of rolled steel can be improved efficiency
