Distributed control system for car-bottom type heat treatment furnace groups

Abstract

The invention provides a distributed control system for car-bottom type heat treatment furnace groups. The distributed control system comprises slave station cabinets, a master control cabinet and at least one heat treatment furnace. The slave station cabinets are arranged on the heat treatment furnaces, each heat treatment furnace comprises a furnace door, a lifting mechanism, a furnace body and a heat-insulation system, each furnace door is connected with the corresponding lifting mechanism, each lifting mechanism is arranged on the corresponding furnace body, each heat-insulation system is arranged in the corresponding furnace body, each furnace body is provided with an air pipeline, a gas pipeline, a smoke discharge pipeline and a burner, both each air pipeline and the corresponding gas pipeline are connected with the corresponding burner, and each smoke discharge pipeline is communicated with the corresponding furnace body. The distributed control system for the car-bottom type heat treatment furnace groups has the advantages that the slave station cabinets are communicated with the master control cabinet via profibus-DP (process field bus-DP), accordingly, large quantities of connecting cables which extend from the slave station cabinets to the master control cabinet can be omitted, the structure of the distributed control system can be simplified and integrated, the distributed control system can be operated conveniently and flexibly, a large quantity of cost can be saved, maintenance workload can be greatly relieved, and the furnace groups can be assuredly smoothly controlled in a centralized manner.

Description

technical field [0001] The invention relates to a control system, in particular to a distributed control system for a trolley-type heat treatment furnace cluster. Background technique [0002] In the current high-speed development of industrial furnace manufacturing and research and development, the electrical control system is an indispensable part. Often, it is realized by electrical appliances when it is impossible to achieve mechanically, and it is easier to achieve perfect equipment through the combination of electrical appliances and machinery. Control and use effects that meet production requirements. For some forged workpieces with high requirements, heat treatment is required after forging, and then mechanical processing is performed. The performance of the heat treatment of the workpiece plays a vital role. However, the traditional control system of the workpiece heat treatment furnace is often difficult to achieve some functions. The maintenance cost is high a...

Problems solved by technology

[0004] The purpose of the present invention is to provide a distributed control system for trolley-type heat treatment furnace clusters to solve the problem in the prior art that the position of the trolley furnace body is scattered and the control room needs to be controlled centrally. The furnace body of the car furnace has a long distance, and some analog signals will cause loss, interference and other problems in the long distance
