Our special
machines for metallurgy

The tap hole drilling and setting machine was developed for renewing the converter tap hole sleeve without moving the machine in only a single operation.

Advantages:

• Extreme reduction of converter downtime
• Immense increase in the availability of the converter
• Precise drilling and positioning of the tap hole sleeve by fixing the machine in the floor
• Camera monitoring of the drilling and setting process

Our slag raking machines are used to remove the floating slag from the liquid metal in the pouring ladles.

Advantages:

• Contamination is efficiently reduced
• Metal loss extremely reduced
• Increase in process speed
• Installation either on or under the platform
• Energy savings through faster process time

The shooter is used for hot repairs on converters and ladles. A telescopic spray lance is positioned by remote controls to the damaged areas in the converter.

Advantages:

• Longer lifetime of the refractory of the converter vessel
• The vessel repairs can be carried out during the running process at temperatures up to 1400°C
• Telescopic spraying boom
• Precise control
• Efficent material application
• The mixing of the refractory material takes place at the front of the spraying lance to avoid material line blockages
• Strong water cooling system for the lance

The HOT BOX MOVER is used to transport the hot slag. It picks up the HOT BOX - the container that contains the hot slag - and transports it from the furnace to the slag bed or the intermediate storage place.

Advantages:

• Significant increase in work safety, because the operator controls the machine by radio remote controls from a safe distance. This eliminates the need for the employee to work in the immediate hot area
• Electro-hydraulic drive for sensitive and precise control of the HOT BOX MOVER
• Abolition of obsolete OTR equipment that is no longer acceptable in today's environment
• Elimination of liquid slag dumping in open pits
• Elimination of the safety risks associated with the transport of liquid slag within the plant. 
• Transition to a fully autonomous solution - removal of the operator from the hazardous activity
• Elimination of slag pit areas - unloading of slag directly at the processing points
• Elimination of explosions and fires
• Elimination of all emmissions
• Increasing the metallic yield
• Increase in metal quality
• Elimination of flame cutting
• Value creation for the plant through reduced service charges and additional improvements in total cost of ownership.

Vision
In the future, the HOT BOX MOVER will also be able to drive autonomously: On a start signal, it will pick up the hot box and drive alone to the desired location, where it automatically unloads the slag
