一、研制经过与试验效果 高炉风口常因接触铁水而被烧坏,或因长时间接触焦炭而被磨漏。风口漏水,一向是靠高炉配管工人和高炉工人凭经验观察发现的。如果发现不及时,轻则大量的水流入炉内,造成炉凉、焦比升高、灌渣以及损坏砖衬降低炉体寿命。重则风口烧穿,酿成重 First, the development through the test results Blast furnace tuyere often due to contact with hot metal was burned, or because of prolonged exposure to coke was ablated. Air leakage, has always been by blast furnace piping workers and blast furnace workers found by empirical observation. If not found in time, ranging from a large amount of water into the furnace, resulting in furnace cooling, coke ratio increased, slag filling and damage brick lining lower furnace life. Heavy burnt wear, lead to heavy
