Due to the melting process of the electric furnace, the molten steel level is constantly changing, in order to maintain the optimal injection angle between the tip and the molten steel level. The manipulator can lift the cross arm vertically as a whole with the change of the height of the molten steel level.
a. Carbon oxygen gun pitch system and swing system
The pitch system can realize the slight adjustment of the tip spray angle, which can assist in slagging and adjust the flow of molten steel. The oscillating system maximizes the working range of the oxygen gun as much as possible.
Carbon oxygen gun pitch angle: 14 ° ~ 25 ° (the limit position of the upper and lower is controlled by the limit tie rod), driven by Ф100/55 L=150 hydraulic cylinder.
b. Carbon oxygen gun swing angle: left 6°; The right 13° (the carbon gun is on the right side of the oxygen gun) is driven by a Ф50/28 L=210 hydraulic cylinder.
c. Mechanical lifting arm
With the change of the height of the molten steel level, the cross arm is lifted vertically as a whole. The optimum injection angle between the tip and the molten steel level is guaranteed.
Mechanical lifting curved arm, there are two fire braces to protect the bending arm, and the two moving parts are metal hose coupling water-cooled fire baffles. Lifting stroke 0~400mm
d. Base and swivel system
Realize the entry and withdrawal of oxygen guns. The distance from the electrode and furnace door can also be adjusted. Ensures minimal loss of refractory materials at the electrode and furnace door. Rotation range 0~93 º
Robotic arm rotation speed: 6°~20°/s (adjustable) driven by Ф80/55 L=1500 hydraulic cylinder. Rotary bearing Ф600.
