Closed loop soft water cooling system 3rd generation new type cooling stave and thinner-synthetic lining have been used in bosh belly and lower stack .

在 炉腹、炉腰和护身下部区域，采用了 软水密闭循环冷却系统、第3代新型冷却壁和组合薄炉衬技术。

For example cooling water circulate constantly through the tuyere hearth staves bosh and inwall cooling plate etc. Measures for prolonging Service Life of the Soft Water Closed Circuit Circulation Cooling System for BF Cooling Stave

例如，冷却 水不停地在风口、炉身、 炉腹和内壁冷却板等部位循环流动。延长高炉冷却壁软水密闭循环冷却系统使用寿命的措施

The cause of clogging on furnace wall and instable running of BF is the relatively great fluctuation of water temperature difference above the middle of bosh .

提出了高炉炉 腹中 部以上 冷却 水温差波动过大是造成4号高炉炉墙结瘤，引起高炉炉况不顺的原因之一。
