Automatic control system and method for nodular cast iron pipe production process

Abstract

The invention provides a nodular cast iron pipe production process information tracking system. An automatic control system for a nodular cast iron pipe production process comprises an annealing furnace area, a zinc spraying area, a water pressure area, a cement smearing and lining area, a curing kiln area, a pitch spraying area, a curing oven area, a bulb tube RFID electronic tag, Ethernet interfaces and a server. The annealing furnace area, the zinc spraying area, the water pressure area, the cement smearing and lining area, the curing kiln area, the pitch spraying area and the curing oven area are connected with the server through the Ethernet interfaces. The bulb tube RFID electronic tag is installed on the inner surface of the straight tube portion of a bulb tube bell mouth. The seven areas are used for reading information of the bulb tube RFID electronic tag, and uploading the information to the server. The server is used for accessing the seven areas through the Ethernet, and reading the bulb tube production information stored in the seven areas. The real-time track record of the whole single-bulb tube process production information in nodular cast iron pipe producing is achieved, operating parameters of technology equipment is beneficial to being optimized, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of metal casting, in particular to an automatic control system and method for the production process of ductile iron pipes. Background technique [0002] The production process of traditional ductile iron pipes is relatively complicated, and there are many types of equipment. The main equipment is usually provided by more than ten equipment suppliers. Although the individual equipment is closely connected by the front and back processes, they all complete each action independently, and each has an independent PLC and Its upper computer and communication software are usually in various forms and are different from each other. [0003] At present, there is no equipment supplier in the world that can provide a full range of ductile iron pipe production equipment from annealing furnaces, zinc spraying machines, hydraulic presses, cement lining machines, asphalt spraying machines, curing furnaces, etc. The onlin...

Problems solved by technology

Therefore, mixed number events often occur in the production process of ductile iron pipes, and it is difficult to prevent them manually

[0006] This production method cannot meet the requirement of recording and traceability of the production information of a single ductile iron pipe, nor can it meet the actual needs of the manufacturer to analyze the production situation of each ductile iron pipe in order to improve the quality of the ductile iron pipe. How to realize the real-time tracking of the production information of a single pipe on the ductile iron pipe production line, so as to complete the automatic control of the ball pipe production line has become a major problem that plagues the ductile iron pipe production industry
