Furnace Tap Hole Machine

Specialized drilling or tapping machine for creating or maintaining furnace tap holes.

The manipulator is applied to the opening and plugging of the slag port in a copper smelting furnace. According to the copper smelting furnace slag port manual operation process and used tools, we developed hole digging robotic arm, which uses automatic control intelligent operation, instead of manual work in high risk and high pollution environment.

Introduction of Furnace Tap Hole Machine

The furnace tap hole machine is generally composed of gun tube device, advance and retreat device, rotation device and angle adjustment device etc. It is used for opening and plugging after smelting in copper smelting furnace. There are three structural forms of furnace tapping machine: electric, hydraulic and pneumatic. The drilling and tapping machine developed by CIC adopts automatic control and intelligent operation, which can replace manual work in high-risk and high pollution environment.

The tapping device comprises a base, a track, strip teeth and meshing mobile gears; The upper part of the base is fixedly provided with a track, the strip teeth are fixedly arranged in the middle of the upper part of the base, and the strip teeth are provided with teeth; The meshing moving gear is arranged on the strip teeth, and the meshing moving gear engages with the strip teeth; The driven wheel is fixedly arranged at the right position of the meshing moving gear, the driving wheel is fixedly arranged at the upper position of the driven wheel, and the driving motor is fixedly arranged at the right position of the driving wheel; The support body is arranged on the track, and the support body moves in contact with the track.

Techinical Specification of Furnace Tap Hole Machine

1. The manipulator has the function of 7-axis linkage. Taking the horizontal center line of the furnace as the reference, it can realize the horizontal movement of the whole machine, with the moving speed of 200 mm / s and the motor driven by gear and rack.

2. Upper swivel 360° Rotation, rotation speed 10°/s. Worm gear transmission is adopted.

3. The robotic arm stretches forward and backward, the stroke is initially determined to be 600mm (it can be adjusted according to the site process requirements), the speed is 700mm/s, the maximum thrust is 1100kg, and the drive is hydraulic motor.

4. The up and down swing angle of the manipulator is 21°, Elevation 3°, Depression angle 18°, Swing speed 5°/s. Hydraulic cylinder drive.

5. The steel drill of the mechanical arm passes through the opening of the crushing hammer, and the striking frequency is 700-1200 bpm; The thrust of the mud blocking cylinder is 31.4 kn, and the mud ball is pushed out through the extended rod piston.

6. The mud ball forming tool is used for forming the end of the mud ball; After once loading, the mud box can automatically take mud for many times.

7. Equipment with stainless steel plate and refractory overall protection, heat insulation, non bonding.

Hydraulic System of Furnace Tap Hole Machine

Pump pressure 90kgf/cm2, Max 110kgf/cm2, 18.5 kW ×2... One of them is standby. Proportional valve control is adopted.
