Filed: 1989-05-29
Abstract: PURPOSE:To prevent a tension arm from being vibrated and to obtain the tape tension controller with high performance not to generate vibration by coupling a turning arm and the tension arm through an elastic body. CONSTITUTION:A turning arm 9, to which turn energizing force is applied by a tension spring 17, and a tension arm 8, which is equipped with a tension post 10 to be in contact with a tape 7 in a tip, are coupled through an elastic body 11.

Abstract: PURPOSE:To prevent the formation of embrittled layers in a furnace wall from tuyeres to a furnace bottom part by blowing forcibly an inert gas such as N2 through the gaps among the bricks to the brick part in the lower part of the tuyeres. CONSTITUTION:The bricks in the side wall part of the hearth of a blast furnace consist of combinations of annular blocks 7 having a relatively large size and small-sized bricks 8. Cooling plates 9 are mounted to the blocks 7. Cooling water is flowed to the plates 9, and gaseous N2 is blown into the gaps among the small-sized brick masonry 8 through the plates 9.
