HTI for you | Summer 2011 Tap hole drilling device in action The tap hole drilling equipment, developed by the new research- and development company TMTborn to drill The tap hole drilling devices of TMT-BBG have got quite a substantial share of the world market. In order to safeguard and extend this lead, the research and development company TMT-BBG developed a new generation of tap hole drilling devices. The almost one year ago founded TMT-BBG Research & Development GmbH has already achieved the first promising results. Beginning of July the company presented their new generation of tap hole drilling devices at the Metec, the international show for metallurgy, steel casting and steel production in Düsseldorf beginning of July. The new equipment will be introduced to the market in autumn this year. Three birds with one stone BBG, produced by BBG in Kapfenberg are used within the pig iron- and steel industry. Iron ore is melted in furnaces to become pig iron, which needs to be extracted from the furnaces quickly and safely. Here the tap hole drilling equipment is used: It precisely drills the so-called tap hole - which is closed during the melting process by means of plugging material – so that the hot, liquid pig iron can flow out. The whole extraction process is called the tapping process. All permanently in use furnaces have to be emptied in regular intervals – approximately every two hours. This process is very intensive, since the machine has to drill the two to four meter long tap hole – depending on the wall thickness of the furnace.
The tap hole itself is only 45 – 60 mm in diameter. State-of-the-art equipment manages the drill in only one to three minutes. Additional the tap hole drilling devices have to be extremely heat proof in order to withstand the heat of the furnace of approximately 800°C. The special feature of the TMT-BBG tap hole drilling devices is that they can manage three things in one go: During the so-called rotary drilling the boring bar is not only going into the furnace (like a drilling machine goes inside the wall) but it is simultaneously going backwards and forwards with one flap motion. With this unique retaliation technology, combining the forward- and backstroke function in one machine, BBG has established an excellent world market position for itself. This equipment makes the use of further machines – without backstroke function (i.e. in opposite direction) an additional striking mechanism would be necessary, in order to retract the boring bar from the tap hole of the furnace. More than that, with this equipment the factors time efficiency and ergonomics are of utmost importance. The whole life low in maintenance Already the previous generation of tap hole drilling devices was characterized by being able to open the tap hole with low strike energy, but high impact rate. Hence, the life-time of the tap hole itself was consequently extended. Based on the customer’s demand, to create the existing equipment much easier regarding maintenance as well as extending the life-time of wear parts, TMT- BBG has now developed the latest generation of tap hole drilling devices. The new models HS 581 and HS 583 (the previous models were HS 571 and HS 573) will be available in autumn 2011. The development of two different models is required by the variety of furnaces, all with specific characteristics. Easy maintenance for example is achieved through simpler handling: Whereas with the previous models mostly the whole machine had to be dismantled for maintenance, now the various works can be done directly and the installed devices. For this purpose amongst others the new protection cover was developed, which has got individual doors directly at the crucial places of the device. This comfortable access shortens service time substantially. More than that, additional functions were integrated, which increase the life-time of wear parts. Also existing customers benefit from these novelties. Those, who already have the previous models, are offered an update by TMT-BBG: Users of the HS 571 can update to HS 581 resp. HS 573 to HS 583. Better safe than sorry … … is the motto of the daily work life at BBG. Therefore, each product that is manufactured by BBG is examined towards it fulfilling the defined requirements. In order to provide this evidence, all BBG products are subjected to an individual testing process. HTI FOR YOU participated in one of those many tests, who were done at the test bench of TMT-BBG – a drilling test with the new tap hole drilling device HS 581. “We are currently testing the resilience of the new tap hole drilling device, in order to extend the life-time of wear parts and consequently to cut the costs for our customers“, explains design manager Werner Schantl, who put his 40 years of experience into the design of the new tap hole drilling device. Also the improved seals in the gear increase the lifetime of the wear parts and provide protection of external influences. The execution of maintenance works is not only to be done in longer intervals but also quicker and more ergonomic, all The TMT-BBG team involved in the development of the new tap hole drilling device: Oskar Kortan, Stefan Kaindlbauer, Andreas Breidler, Romain Clesen, Frank Helsper, Werner Schantl, Michael Wolfsberger (not in the picture)
