What Are You Looking For?
Metallurgical production enterprises use computers for automatic control and management. The automation control of metallurgical production processes includes the control of main production processes such as mining, beneficiation (see beneficiation automation), smelting (see blast furnace automation, converter automation), casting (see continuous casting automation), rolling (see continuous rolling mill control system), as well as water supply, electricity, heat, oxygen, and gas. Modern metallurgical enterprises use computers to integrate production process control and production management into a unified whole, greatly improving the level of automation.
In the 1950s, sequential controllers and analog regulators began to be used for metallurgical production process control. In the 1960s, the UK established its first fully computerized hot rolled strip mill. In the 1970s, with the promotion of microcomputers, metallurgical enterprises also began to use computers to establish complete computer control and management systems. Realizing metallurgical automation can greatly improve labor productivity and product quality, reduce the occupation of working capital, improve labor conditions, and achieve high economic benefits.
