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.
The UNIDACHS tap hole repair machine 423, a solution especially developed for removing and setting the tap hole sleeve, is positioned precisely with the aid of a camera and an angle indicator. From this position, the percussion drill removes the worn out tap hole sleeve quickly and precisely. Without having to re-position the machine, the new tap hole sleeve is set and held in position until it is fixed. This saves valuable production time and reduces costs. The tap hole drill is also available in a remote-controlled version and optionally with or without an operaters cabin.
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 service life 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.
When debricking, using the UNIDACHS allows work to be carried out on the hot converters immediately after the last heat. This saves production time and money, because work can begin before the converter has cooled down completely.
„The new debricking machine is one of the particularly important components of our multi-million-euro investment programme. In terms of power and speed, it fully meets the new requirements of the modernised, now much more powerful converter. Ensuring the efficient operation of the entire technological process, which contributes decisively to the high quality of our end products. Not only the high performance, but also the reliability and environmental friendliness of the new machine played an important role in the purchase decision."
