Device for controlling the speed of cutting using the oxygen sputter in cutting the slab of a continuous caster

摘要

In the present invention, in the cutting speed adjustment device of the slab, the upper portion of the sensing plate attached to the ring, the cutting oxygen sensing plate is fixed and the lower part is secured via additional counterweights to balance connecting brackets, sensing plate attached to the ring, the primary shaft is fitted loosely detected, the detector detects the car, the two ends of the shaft, cutting oxygen bearing fitted car moving pipe detection and deterrence car fixed bar to enable rotation detection switch, detects car movement switch mounting bracket hole of the balance weight made of a plurality of sensor and the detection switch is installed by detecting the angle for the switch bar are gangcheolseon the through hole of the upper interconnection to be fixed to the pipe By providing the cutting speed adjustment device using a slab cutting performance during cutting, characterized in that the oxygen sensing bar to move the sensing switch in accordance with the movement of the cutting oxygen sensing plate. ; of the slab according to the invention and by providing a non-cut portion to prevent the slab with good cut off in a later process step the plate during rolling defective factor in advance, there is an effect of improving the cutting efficiency.
