TEN FEATURED TECHNOLOGIES OF IMPROVED TOP COMBUSTION HOT BLAST STOVE

Technology of improved top combustion hot blast stove

In 2001, SDM was the first to introduce Kalugin top combustion hot blast stove (HBS) technology in China. After absorption and improvement, it was successfully applied to the production practice of blast furnace. The first top combustion HBS in China (for Laiwu Steel 3# 750m3 BF) was designed. SDM has 6 patents for invention and 7 patents for utility models, forming an advanced and reliable top combustion HBS technology with independent intellectual property rights, which is characterized by high air temperature, low investment and long service life.
