METHOD AND APPARATUS FOR AUTOMATICALLY PUNCHING THE TUYERES OF A CONVERTER |
摘要 |
<p>NO-4-23955M/KK/80 Method and apparatus for punching the tuyeres of a converter with a mechanical puncher mounted upon a carriage running on rails. Light intercepting plates encoded by light transmission holes are disposed opposite each tuyere. Light is shone towards the light intercepting plates and detected on the opposite side thereof by photoelectric elements the outputs of which are coupled to a digital processor which controls the speed and position of the carriage. The mechanical puncher has two cylinders each of which drives two punching rods to successively punch the tuyeres. If it is impossible to punch a tuyere with the mechanical puncher were moving in one direction, the position of the puncher is shifted by one tuyere to start the punching again in the opposite direction.</p> |
