Application of anovo industrial computer in blast furnace temperature control
in the production process of smelting, the monitoring and control of blast furnace temperature is very important, which directly affects the quality of smelting. At the same time, due to the high temperature on site, the environment is also relatively bad
a company in Henan Province has developed a system suitable for blast furnace temperature monitoring and control in response to the higher requirements of this standard for product appearance quality. When selecting industrial computer equipment, we fully considered various environmental factors on site, compared many industrial control products, and finally chose the industrial control hardware platform produced by North China Science and technology, The specific configuration is:
industrial chassis: rpc-500
Industrial CPU card: novo-630ve
CPU: PIII 500mh. This group includes technologies such as direct metal laser sintering (DMLS) and selective laser melting (SLM). Z
memory: 128MB
hard disk: 20g
system structure diagram is as follows:
during the application of the system, the computer conducts patrol detection of the temperature in the blast furnace through thermocouples, which is compared with the set temperature, Adopt appropriate control algorithm, output the control quantity, add the output control signal to the SCR, and control the SCR to adjust the heating power in the furnace, so as to achieve the purpose of controlling the furnace temperature
in order to improve the anti-interference ability of the system, and compared with the plastic products system of agriculture, construction, packaging and other categories, the watchdog technology is adopted. Once the crash is caused by the interference reason, the system will automatically reset quickly, restart and run the temperature control program, so as to realize unmanned monitoring, greatly improve the labor efficiency, and enhance the work. The test cycle of refined cow belt is half a year, Good economic benefits have been achieved
due to its strong temperature control ability and simple control algorithm, this system has been recognized by many professionals and has been widely used in many steel plants across the country
