Design and Development of Training System for Teaching on Shaft Furnace Mechatronics

Abstract

Based on the practical teaching requirements of metallurgical engineering, a cold position training device on blast furnace was designed in line with actual production. The control system adopts the integrated control cabinet and its design of the training device is implemented by the PLC of Siemens S7-300 and the configuration software of Real Bridge. The control mode includes two kinds of modes, which are remote control and manual control. Through the development and use of blast furnace training devices, the teaching content can be visualized. This device has been put into use in colleges, and obtained the good training effect. is blown and oil, coal, natural gas or other fuels are injected from the tuyere of the blast furnace bottom. The iron ore into the blast mainly is compounds of iron and oxygen. At high temperatures, the carbon of the coke and the injection material and carbon monoxide from carbon combustion can capture the oxygen from the iron ore to get iron and this process is called reduction. Molten iron is released from the taphole. The gangue in the iron ore and the ash in the coke and injection material are combined with the flux of limestone to generate slag, which is discharged from cinder notch. The coal gas exporting from the top of the furnace can be used as industrial gas after dedusting. Modern blast furnace can also use the high pressure of the top to generate electricity with the exporting gas.
