The new method for producing a high-strength steel packaged in our successful trial, the process comprising the steps of uncoiling, flat head, butt, entry looper, trimming, heat treatment, Portland, drain outlet looper, waxed and winding, unwinding steel, flat head, butt, entry looper, drain outlet looper, waxing and winding conventional methods are used, respectively, in the ordinary decoiler, flat head machine, welding machine, entry looper machine, drain rack, the export of live sets of machines, wax and winding slot machine on, it is characterized by: (1) open-book, flat head, butt, entry looper, trimming, heat treatment, Portland, drain, export of live sets, wax and rewinding all process steps in the same production line continuous line is finished, pulling and tensioning tensioning machine all process steps through the process of connecting strip and the tractor in the same production line; (2) strip trimming in two opposing rollers and universal frame consisting of two pairs of horizontal rollers used nip deformed manner; followed by vertical roll strip edges, horizontal roll surface, trimming process is completed by way of plastic deformation ; (3) the use of steel heat treatment quenching and tempering, quenching carried out in the quenching furnace, the quenching temperature is

800 ~ 960 ℃, the use of water quenching, tempering includes tempering tempering heating and insulation, were tempered at tempering furnace and holding furnace, tempering heating temperature and Tempering temperature are 450 ~ 650 ℃, tempering after water-cooled; quenching time, tempering heating time and tempering steel holding time were traces of time in the hardening furnace, tempering furnace and tempering holding furnace; and (4) steel flange in holding furnace tempering furnace and tempering done by rapid induction heating and insulation process.
