On Ladle Tracing System Based On Laser Ranging Technology And Radio Frequency Card Technology

Steel products are basically oversupplied under fiercely competition of the market at present. The profit of steel products is nearly the lowest compared with other industrial products. The production cost must be reduced as much as possible while meeting the request quality and date of delivery. The construction of informationize must be strengthened in order to improve the profit ability of steel enterprise. Logistic management is a main part of informationize of steel enterprise. In a steelmaking plant, the transfer of ladle covers the whole process of steelmaking. The tracing of ladle is the key point to solve the problem of material tracing in steelmaking process. Ladle tracing and management is always a research task for steel enterprise.The aim of this research is to develop and design ladle tracing system based on laser ranging technology and radio frequency card technology. The content are listed as follows,(1) Explains the situation and problems of ladle tracing system which is in use. The plan of project improvement is studied based on the situation of ladle transfer management in steelmaking plant No.2in Shougang Qiangang.(2) Designs the ladle car tracing system based on laser ranging technology. Explains the significance of this system and proposes the hardware plan of the system. Realizes the data collection of laser ranging machine through software program, and analyses the data applying the51series single chip. Displays the measured distance through the designed LED numeral tube dynamic display circuit.(3) Designs the crane tracing system based on radio frequency card technology. Explains the significance of this system, analyses the situation of crane tracing technology at present and proposes the hardware plan of the system. Realizes the data collection of crane tracing through electronic label and wireless communication technology. Realizes crane position confirmation through PROFIBUS and software program.(4) Briefly introduced the facility arrangement of steelmaking plant No.2. Explains in details about apply results of ladle car tracing system and crane tracing system in steelmaking process. Finally realizes the design and application of continuous tracing system of the ladle.
