摘　　要：高温合金-陶瓷弯头单体自冷却喷煤枪具有耐磨蚀、抗氧化和抗烧损等优点,枪体的热强度高。与普通不锈钢喷煤枪相比,喷枪使用寿命长,可以有助于增加喷煤量、缓解风口磨蚀、减轻工人劳动强度。首钢5座高炉自1998年8月起开始使用高温合金喷煤枪,取得了明显的成效。The PCI lance made of high temperature alloy and ceramic bent is wear-resisting,oxide-resisting and heat-resisting. It is high in hot strength. Compared with, normal stainless PCI lance, the lance can increase service time,stabilize PCI operation,raise PCI rate,reduce tuyere abrasion, and decrease worker' s labor significantly. The lance has been used in all five blast furnaces of Shougang since August 1998,and the results are excellent.
