Strong wind cooling system for medium plate heat treatment

Abstract

The invention discloses a strong wind cooling system for medium plate heat treatment, which comprises a cooling air supply system and a control system; a steel plate is performed with strong wind cooling in a cooling chamber arranged along a conveying roller way, a plurality of cooling segments are held in the cooling chamber, each cooling segment is provided with an air supply system and a heat exchanger, and the cooling and cooling air circulation of the steel plate at the cooling segment are controlled by a process control system; the control mode of the conveying roller way comprises single transmission and group frequency conversion; the control system is composed of a transmission instrument system, a PLC system and a process control system; the process control system is used for dispatching a model parameter database according to a production plan, regulating a strong wind cooling strategy by a created strong wind cooling mathematical model, calculating a strong wind cooling procedure, and sending the cooling procedure to the PLC system to be executed and displayed on an interface; the process control system triggers the PLC to work by an inlet metal detector signal, and the PLC system is used for respectively executing the working procedures of the air supply system and the roller way system. The system disclosed by the invention has the advantages of improving the production efficiency and simplifies the operation steps.

Description

technical field [0001] The invention belongs to the technical field of heat treatment equipment and process control, and in particular relates to a strong wind cooling system for heat treatment of medium and thick plates. Background technique [0002] At present, the role of air cooling in the field of heat treatment of medium and thick plates is limited. On the one hand, due to the small cooling capacity of existing air cooling equipment, the steel types and specifications of the medium and thick plates to be treated are greatly restricted; The control is difficult, and most of the time it can only be "cooled to the end", and the cooling path control cannot be realized. Strong wind cooling is a convective heat transfer process generated when cooling air flows through a high-temperature heat transfer surface under the action of pressure difference. Due to the large local heat transfer coefficient generated, this cooling form has been widely used in electric power, chemical a...

AI Technical Summary

Problems solved by technology

The structure of the air duct used in this patent is relatively simple, which is prone to the problem of uneven cooling

At the same time, each air duct is connected to each other, which cannot achieve regional cooling, and the cooling process control flexibility is small

In addition, this patent is not equipped with a process control system, which cannot provide more accurate cooling strategies and cooling procedures, and the overall control degree of the cooling process is not high
