Problems solved by technology

[0002] Before the billet comes out of the heating furnace and is ready to be rolled in the rolling mill, due to the requirements of the steel type and process, it must reach a certain temperature before it can be rolled in the rolling mill. As a result, the billet has to be warmed in the air, which makes the rolling efficiency low and the enterprise benefit is affected. influences

Abstract

The invention relates to a cooling system for intermediate steel billets. The cooling system is composed of a water supply pipeline, a PLC control system, upper cooling water beams, lower cooling water beams and an infrared temperature measuring device, wherein the water supply pipeline is divided into four branch water supply pipelines, each branch water supply pipeline is connected with four cooling water beams and is provided with a set of flow control device, and the flow control devices are controlled by the PLC control system. The cooling system for the intermediate steel billets is novel and reasonable in structure, high in degree of automation and cooling precision, and low in maintenance and operation cost, and can be applied to cooling before rolling of steel billets, steel plates and structural steel in the metallurgical industry.

Description

technical field [0001] The invention relates to a cooling system control structure before rolling of steel billets, steel plates and section steels in the metallurgical industry, in particular to a steel billet intermediate billet cooling system. Background technique [0002] Before the billet comes out of the heating furnace and is ready to be rolled in the rolling mill, due to the requirements of the steel type and process, it must reach a certain temperature before it can be rolled in the rolling mill. As a result, the billet has to be warmed in the air, which makes the rolling efficiency low and the enterprise benefit is affected. influences. Contents of the invention [0003] In order to solve the above problems, the present invention provides a billet intermediate billet cooling system with simple structure, reduced waiting time and improved rolling efficiency. [0004] The technical solution of the present invention is: the system is composed of water supply pipeli...
