AI Technical Summary
Existing taphole machines with reverse tapping are complex in structure, large in size, heavy in weight, have a high failure rate and are inconvenient to maintain, making it difficult to meet the taphole opening requirements of large blast furnaces.
Design a gas-hydraulic combined opening machine, comprising a hydraulic impact section, a hydraulic rotating section, a pneumatic impact section, and a front assembly. By combining hydraulic and pneumatic power, the machine enables the forward, rotating, and backward movement of the vibrating rod, simplifying the structure and reducing the failure rate.
It has achieved a simple structure, light weight, low failure rate, and easy maintenance of an opening machine, which can efficiently complete the opening of iron tapholes and quickly remove the vibrating rod.
