Customised solutions for converter maintenance

Converter mouth cleaning and de-skulling

Regular cleaning of the converter's mouth and cone ensures smooth production flow and keeps production capacity at a high level. The UNIDACHS can be used to carry out work on the hot converter: The telescopic boom is the machine operator's "long arm" for this, allowing work to be carried out in the heat from a safe distance.

Drilling and setting the tap hole sleeve

The UNIDACHS tap hole repair machine 423, a solution especially developed for removing and setting the tap hole sleeve in converter. Equipped with a precision camera and angle indicator, the machine ensures exact positioning for efficient operation. Once positioned, the percussion drill swiftly and accurately removes the worn-out tap hole sleeve. Without needing to reposition, the machine seamlessly inserts and holds the new sleeve in place until it is securely fixed in converter. This streamlined process saves valuable production time and reduces operational costs. The Tap hole drilling machine is available in both remote-controlled and manual versions, with the additional option of an operator’s cabin, offering flexibility to suit diverse operational requirements.

Hot converter repair

When repairing the refractory on the hot converter, the SHOOTER, a spraying manipulator with telescopic and 380° rotatable spraying lance, sprays the refractory material exactly to the place where the lining has to be repaired. This increases the durability of the converter. The unshaped mass is fed to the SHOOTER via a pressure conveyor system, which we also offer in the total solution package.
