Travel switch S3, electromagnet Y6 power loss, while electromagnet Y8 obtain electric, triggering after the piston rod of upper gripping apparatus rotary oil cylinder is fully extended
Travel switch S4, electromagnet Y8 power loss, while electromagnet Y3 obtain electric, and the piston rod of large arm rotary oil cylinder triggers stroke after withdrawing L3
Power loss, system unloaded are reached simultaneously by the turning positioning mechanical that monoblock type turns over slag workbench simultaneously by switch S5, electromagnet Y1 and Y3
Clamping slag waggon compartment realizes predetermined slag dumping preparation；
Then, the second control button is pressed, electromagnet Y1 and Y3 obtain electric, and the piston rod of large arm rotary oil cylinder triggers after withdrawing completely
Travel switch S6, electromagnet Y3 power loss, while electromagnet Y11 obtain it is electric, large arm stretch oil cylinder piston rod withdraw completely after trigger
Power loss, system unloaded realize the overturning localization machine that monoblock type turns over slag workbench simultaneously by travel switch S7, electromagnet Y1 and Y11
Slag dumping of the movement of structure to slag waggon compartment；
Finally, pressing third control button, electromagnet Y1 and Y10 obtain electric, touching after the piston rod of large arm stretching oil cylinder is fully extended
