Description

technical field [0001] The invention relates to a combustion control system, which is suitable for the control of the combustion process of an alloy baking furnace. Background technique [0002] At present, in order to produce high-quality molten steel, it is necessary to heat the added alloy to minimize the amount of hydrogen brought into the alloy and the influence on the temperature of molten steel, so as to achieve the purpose of smelting high-quality steel. The existing alloy heating basically adopts ordinary alloy baking furnace technology, and its combustion system mainly relies on the experience of operators to judge and operate the combustion process. This combustion system has the following disadvantages: [0003] 1) Manual ignition is adopted, the ignition task is heavy, and the success rate of ignition is low, and in the process of use, the flame may be extinguished and cannot be detected in time, and toxic gas leaks out, causing safety accidents; [0004] 2) Th...

AI Technical Summary

Problems solved by technology

[0003] 1) Manual ignition is adopted, the ignition task is heavy, and the success rate of ignition is low, and in the process of use, the flame may be extinguished and cannot be detected in time, and toxic gas leaks out, causing safety accidents;

[0004] 2) The temperature of the alloy material is uncontrollable, there is no temperature monitoring device, the temperature can only be judged artificially, the error is large, and the process stability is poor;

[0005] 3) The pressure and flow of combustion and combustion-supporting gas are uncontrollable, and the input volume of combustion and combustion-supporting gas cannot be effectively adjusted, and the mixed gas ratio of combustion and combustion-supporting gas can be accurately adjusted, resulting in a great waste of combustion gas;

[0006] 4) The quality and technical requirements of operators are high, which greatly increases the corresponding labor costs

Its disadvantages are poor voltage stability, inability to detect temperature and flame extinguishment
