济钢120t转炉进铁方式探讨

济钢第三炼钢厂在"十五"期间将建设成为3座120t转炉、年产量450万t的大型炼钢厂,转炉铁水的进铁方式将影响着新东区的工序与生产组织。结合济钢的工艺状况对鱼雷罐进铁、混铁炉进铁、铁水罐直接进铁方式进行了比较,认为选取鱼雷罐进铁方式比较合理。

Sillimanite, Kyanite and Andalusite in China and Their Applications Part II: Their Applications in Refractories to Improve Resistance to Creep and Thermal Shock

As a second part under the title, this paper introduces the applications of sillimanite group minerals (SGM) in refractory products for hot blast stove, blast furnace, torpedo, hot metal mixer, etc., with emphases on their uses in the low creep and thermal shock resistant bricks for tuyere and iron notch of blast furnace and checker brick and ceramic burner of hot blast stove, taking use of their phase transformation to form primary mullite and secondary mullite, accompanied by volume expansion. The developed SGM containing refractories have found wide uses in major domestic iron and steel making plants to meet the requirements of longer service life, higher service temperature and intensified operations.

鱼雷型混铁车走行装置检修技术创新与应用

邯钢运输部鱼雷型混铁车在运用过程中,走行装置各部件磨损严重,尤其是摇枕、侧架间隙磨损超限,针对以上问题在检修时对鱼雷型混铁车侧架及摇枕等制作专用的校验模具,通过改进轮对堆焊旋修、鱼雷型混铁车走行装置检修技术,解决了检修过程中磨损、拆装、清洗、加工等难题,从而提高了车辆检修效率,增加了车辆安全运用系数,延长了车辆使用寿命,降低了工人劳动强度。
