Reasons for the Difficulties in Clay Gunning in No.1BF Taphole and Its Measures;
1号高炉铁口打泥困难的原因分析与对策
In order to assure the BF's safety production, protect the taphole and the part around it, lighten erosion of taphole brickliner, the taphole clay containing Titanium is used to maintain taphole.
为保证高炉安全生产 ,保护铁口及炉缸的铁口周围部分 ,减轻铁口砖衬的侵蚀 ,探讨利用含钛炮泥维护铁口。
In order to increase the hot metal throughput of main trough, some reforms to the trough were carried out, and in order to realize zero-interval tapping and meet the needs for smooth operation and intensified smelting of BF, the management and maintenance of taphole were strengthened at Maanshan Steel's 2500 m~3 BF.
马钢2500m~3高炉通过对渣铁沟进行技术改造,增加了主沟通铁量;通过加强铁口管理与维护,实现了零间隔出铁,满足了高炉强化冶炼的需要。
Based on the production experience and the analysis on the aspects of iron notch depth,notch opening situation and slag tapping from the iron notch,the reasonable composition of gun mud is found out to improve its quality,and as a result,the iron tapping from the notch gets obvious improved.
根据唐钢2 000m3高炉的生产实践经验,从铁口深度、开口情况、铁口出渣、铁情况进行了分析,找出了改进炮泥质量的合理配比,炉前铁口出铁状况明显好转。
Through adopting the technical measures such as local tuyere blowing above iron notch, burning iron notch with rich oxygen lance, tapping from iron notch, discharging slag and hot metal timely, adding coke in concentrative and de-concentrative forms and drilling the tuyere timely and so on, the accident of hearth chill was treated effectively.
通过采取铁口上方局部风口送风、富氧枪烧铁口、铁口出铁、及时排放渣铁、集中与分散加焦和适时打风口等措施 ,有效地处理了炉缸冻结事
In addition,the main reason for iron notch disorder of No.
结合大修前炉体破损情况,对这2座高炉第一代炉役生产中出现的问题进行调查研究,认为7号高炉在应用大型模块和炉腰冷却壁设计上存在不足,高炉边缘气流发展,操作炉型不合理,炉况不顺;7号高炉炉底温度偏高是炉底炭砖渗铁造成的,6号高炉炉底温度偏高是炉底串煤气所致;7号高炉铁口失常的主要原因是铁口组合砖损坏严重和该部位炉壳开裂,并提出了改进建议。
tapping hole is an integrated one in many aspects.
高炉炉前铁口管理是多方面的综合管理,对2#1880m3高炉铁口出现的问题采取针对性的措施,抓住操作上的可控因素,铁口工作状况取得明显进步。
