Heating furnaces are energy-consuming equipment in the steel industry, accounting for about 70% of the energy consumption of the rolling process, directly affecting the production cost and energy consumption of the steel industry. Due to scheduling methods, operational problems and control systems that did not meet the requirements, the improvement rate did not work as expected.

• The continuous casting billet is implemented, and the fuel consumption has not decreased as expected.
• Manual temperature control of heating furnaces is difficult to adapt to production environments with high strength, large scale or high precision requirements.
• There are large errors in the two-dimensional and three-dimensional temperature fields in the furnace.
• Problems with excessive or insufficient residual oxygen.

Heating furnaces are the main energy-consuming equipment in the steel industry, accounting for about 10% of the total energy consumption of steel enterprises and about 70% of the energy consumption of the rolling process, which directly affects the production cost and energy consumption of the steel industry.

iFurnace is a newly developed intelligent secondary control system by ICSC. In response to the heating furnace process and energy-saving and environmental protection needs, it is installed in the communication between the first and second level of the heating furnace. It has an intelligent optimization control strategy to meet the automatic temperature control of multiple and small amounts of steel types, ensuring that the heating furnace can achieve a temperature quality hit and energy-saving effect when it is produced by the heating furnace.

 Furnace pressure prediction control: Predict the degree of air inhalation, automatically adjust the furnace pressure, and effectively inhibit air inhalation.

 Hypoxic furnace atmosphere control: Application software simulation, automatically adjust the air-fuel ratio of each furnace area, maintain the optimal combustion state, and realize the control of the hypoxia furnace atmosphere and exhaust gas low oxygen in the high-temperature furnace area.

 Intelligent temperature control: According to process requirements, three-dimensional embryo temperature calculation is applied, and the optimal temperature increase temperature control is adjusted to achieve rapid interweaving of hot and cold embryos, adapt to the wide range of steel types to effectively control hits, save energy and improve the quality of steel embryos.

 Process visualization: Provides process monitoring, equipment status diagnosis, and trend analysis tools.

 Energy saving: The energy-saving and efficient hot rolling farm with automatic temperature control is about 3%, and the small steel embryo factory of bar steel mills is about 5~10%.

 Reduce waste: Reduce billet burn loss up to 0.06%.

 Reduce the order: The annual output of four hot-rolled production lines is 12.6 million tons, which can reduce CO2 emissions by 9,000 tons and 7.7ppmNOx emissions.

 Improve embryo temperature quality: Taking into account the uniformity of three-dimensional embryo temperature, optimize the energy-saving amplitude and temperature homogeneity, effectively improving the temperature homogeneity of steel embryos.
