Definitions

  • the invention relates to a process for continuous Manufacture of finished profiles from metal with a Rolled structure, in particular geometrically complex profiles such as e.g. B. beams, sheet piles, railroad tracks and Track material in which a continuously cast Endless strand with a cast structure without subdivision and intermediate heating a rolling mill, especially a universal rolling mill is fed.
  • the invention also relates to a Arrangement for performing the method.
  • the cross section of the cast strand so far to the Cross section of the finished profile approximates that the cast structure of the strand in the rolling structure of the finished profile converts the minimum degree of stretching of the strand in the shaped steel rolling mill, can produce high production output at low Realize the rolling speed in the steel forming mill. They are compared to conventional reversing rolling mills Rolling speeds are about 7 times lower. The lower rolling speeds increase the work and Operational reliability and reduce noise when operating an arrangement for performing the method. At the same time, the quality of the Finished profile improved.
  • the cross section of the cast can be changed by changing the mold Strands to a variety of different finished profiles can be approximated, with those given above have beneficial effects.
  • Another advantage of the Continuous casting rolls result in almost during rolling no head ends and foot ends with dangerous sharp tongues occur on the web and flanges. After rolling it will Finished profile fed to a cooling section and then with With the help of a moving lower part device in sections divided, the length of which is a multiple of the length of the ready-to-sell divided finished profile.
  • the Continuous casting rolls enables both in upstream and also in subordinate areas of the order for Perform the procedure using slow-moving Machines, such as band saws for dividing Sales lengths.
  • the liquid steel area shown on the left consists of a pan 1, a tundish 2 and a casting wheel 3.
  • the Tundish arranged under pan 1 has the task of Align the pouring jet on the mold of the casting wheel 3 and serves as a buffer during the pan change.
  • That too Casting wheel 3 known per se comprises an endless rotating one Steel chain, scraper and cleaning accessories as well as coolant.
  • the steel chain closes a groove on approximately one Quarter of the wheel circumference of the casting wheel 3 and forms with that Wheel the mold.
  • the steel runs from the Tundish 2 into the mold and solidifies during the quarter turn of the casting wheel 3 so far that a solid shell has formed.
  • This partially solidified strand is connected in a downstream Arrangement 4 descaled and immediately several, in the embodiment four roll stands 5 fed out the thin pre-profile of the mold close to the final dimension, which the Finished profile is geometrically similar, for example one Form the double-T beam.
  • Under the process data given by way of example results in 6000 operating hours per year an annual production output of 1,440,000 tons.
  • the low rolling speed of the roll stands 5 allows dividing the continuously manufactured finished profile with a rotating saw 7 in sections that with the help of a cross conveyor 8 with integrated therein Straightening system 9 of a stacking system 10 for forming single or multi-layer layers (packages) of the sections supplied become.
  • the packages arrive from the stacking system 10 via a roller table 11 to a further lower part device 12.
  • the packages have a total weight of around 30 tons. Consequently can use the cycle times to divide the sections in ready-to-sell finished profiles in the further lower part device 12 large be chosen so that slowly running machines, such as band saws, for dividing come into question.
