Background
The tundish is a refractory vessel used in short-run steelmaking, and receives molten steel poured from a ladle first, and then distributes the molten steel to each crystallizer through a tundish nozzle. Iron and steel is an important basic raw material, and plays a very important role in economic development of various countries in the world. The tundish roaster is equipment for burning coal gas to heat the tundish, the tundish roaster is a very important link in continuous casting production, the temperature is roasted excessively and can reduce the service life of refractory materials, the temperature is roasted and can not reduce the temperature of the tundish enough, the tundish can be cooled down seriously and can cause casting failure, so the roasting effect of the tundish roaster is very important. In recent years, with the increasing maturity and popularization of a high-temperature air combustion technology (abbreviated as HTAC), there are many tundish roasters which are produced by burning natural gas in China by using an air single heat storage technology, but the tundish roasters are not successful or have ideal application effects, and finally the tundish roasters are changed into a conventional burner burning mode, and the reason is mainly the burner mode and a burning control system thereof.
Therefore, it is very important to develop a new combustion technology that is technically reliable and environmentally friendly to effectively reduce the converter gas fuel consumption of the tundish roaster, and to reduce the fuel cost.
