摘要： PURPOSE:To control the distribution of blast furnace charging materials adequately at the furnace top by providing a sliding chute swivelably to the leading end of a swiveling chute. CONSTITUTION:A swiveling chute 7 is swiveled by the driving force of a motor 1 for swiveling, and the chute 7 is tilted by the driving force of a motor 2 for tilting. A mechanism of sliding a sliding chute 9 is provided to this mechanism. More specifically, the revolutions of the motor 3 are transmitted to a gear 3-(g) coaxial to a vertical chute 12 by means of a worm gear 3-(a), gears 3-(b), 3-(c), 3-(d), and a gear 3-(f) coaxial to the revolution of the gear 3-(d). Further, they are transmitted from the gear 3-(h) coaxial and integral to and with the gear 3-(g) to a shaft 3-(l) by means of a gear 3-(i), a worm gear 3-(j), and a gear 3-(k), by which a crank 4 integral with the shaft 3-(l) is titled, and the sliding chute 9 mounted to the chute 7 by means of a rail 10 is slided by a link 5 having a fixed point 6 at the chute 7 and a fixed point 8 at the chute 9.
摘要翻译：目的：通过提供滑动滑槽可旋转地旋转滑槽的前端来控制高炉充填材料在炉顶上的分布。构成：旋转滑槽7由电动机1的驱动力旋转以进行旋转，滑槽7由电动机2的驱动力倾斜而倾斜。提供滑动滑槽9的机构。更具体地说，马达3的转数通过蜗轮3-（a），齿轮3-（b），3-（c），齿轮3，以及与齿轮3（d）的转动同轴的齿轮3（f）。此外，它们通过齿轮3（i）从齿轮3（h）传递到齿轮3（h）并与齿轮3（g）一体地传递到轴3-（1），蜗轮3- （j）和齿轮3（k），通过该齿轮3-（k），与轴3-（1）成一体的曲柄4被标题，并且通过轨道10安装到滑槽7的滑动滑槽9被滑动连杆5在滑槽7处具有固定点6，在滑槽9处具有固定点8。

摘要： PURPOSE: To improve size distribution of stuff cast into a furnace by dividing a rotary chute of a casting device at the top of a bell-less furnace into a main body and a tip part so as to allow its free slanting motion.
CONSTITUTION: A rotary chute 6 is divided into a main body 6A and a tip part 7A which is made vertically rotatable with respect to the body 6A by means of a pin 11. Further, a fixed point 14 provided on a bracket 13 rotating around a furnace center 12, a pin 15 provided on the side of the main body 6A and a pin 16 provided on the side of the tip part 7A are connected by means of a link mechanism. When the chute 6 is put into slanting motion, the tip part 7A can change an angle α of slanting motion in accordance with an angle θ of slanting motion of the main body 6A. In case the angle θ is wide, the tip part 7A stretches instead of making a slanting motion so that raw material may be cast closely to an interior wall of a furnace. In case the angle θ is narrow, the tip part 7A declines so that expansion of width of a locus for the raw material dropping may be prevented.

摘要翻译：目的：通过将无钟炉顶部的铸造装置的旋转滑槽分为主体和尖端部分，以便使其自由倾斜运动，从而改善投入炉内的物料的尺寸分布。构成：旋转斜槽6分为主体6A和尖端部7A，其通过销11相对于主体6A可竖直旋转。此外，设置在支架13上的固定点14围绕炉中心12，设置在主体6A侧的销15和设置在前端部7A侧的销16通过连杆机构连接。当斜槽6倾斜运动时，尖端部7A可以根据主体6A的倾斜运动的角度θ来改变倾斜运动的角度α。在角度θ宽的情况下，尖端部分7A不是倾斜的运动而延伸，使得原材料可以靠近炉子的内壁浇铸。在角度θ较窄的情况下，尖端部7A下降，可以防止原料落下的轨迹的宽度扩大。

摘要： PURPOSE:To make a control system simple and to improve the accuracy of metering and the accuracy of the blowing rate control by performing blowing of fuel into a blast furnace before an annular pipe. CONSTITUTION:Blowing of fuel into a blast furnace 9 is accomplished by a hot blast main pipe 4 between an annular pipe 17 and a hot stove 3. The supply of fuel into the main pipe 4 is accomplished via burner 7A from a fuel transport main pipe 14, and the rate of fuel supply is controlled by a fuel flow rate control device 12 installed to the main pipe 14. Namely, the air flow rate to be supplied to the hot stove 3 is detected with a blast flowmeter 2, the detected value thereof is inputted to a fuel blow control device 16. The device 16 controls the device 12 by referring to the amount of the blast to be supplied into the hot stove 3. Thereby, the fuel is supplied into the pipe 4 within the range wherein the blown fuel burns thoroughly. According to this method, the accuracy of fuel blow improves and the smooth blast furnace operation is accomplished.
