Description
Technical field
The utility model relates to field of steel metallurgy, is specifically related to a kind of steekle mill production line preparing roughing mill, produces the narrow coils of hot-rolled steel of deformation temperature range by rational Equipments Setting and technological process.
Background technology
The design feature of steekle mill production line is configured with a coiler furnace respectively in the inlet/outlet side of reversing steckel mill.Be incubated because band steel can enter in coiler furnace in the operation of rolling, thus decrease the temperature drop of band steel, be therefore applicable to the steel grade that rolling deformation temperature range is narrow, as stainless steel and special steel etc.The features such as compared to hot continuous rolling production line, steekle mill production line has that investment comparatively economizes, floor space is less, produce and layout pattern is flexible.
Traditional steekle mill production-line arrangement pattern mainly contains following four kinds, is respectively:
(1) the steekle mill production line of single chassis layout pattern is four roller reversible steekle mills of the attached edger roll of 1 frame band, and its product produced is mainly Hot-rolled Middle Plate.
(2) the steekle mill production line of 1+1 layout pattern is four roller reversible roughing mill+1 frame four roller reversible steekle mills of the attached edger roll of 1 frame band, its main feature produces the narrow coils of hot-rolled steel of deformation temperature range, but because steekle mill reversible rolling passage is more, namely steel is with to enter in coiler furnace the number of times carrying out being incubated more, afterbody simultaneously with steel can not enter in coiler furnace and be incubated, thus make belt steel surface produce more secondary oxidation iron sheet, and make the larger with middle portion temperature difference end to end of band steel, cause its surface quality poor lower with lumber recovery.
(3) the steekle mill production line of 1+1+3 layout pattern is four roller reversible roughing mill+1 frame four roller reversible steekle mill+3 frame mm finishing mill unit of the attached edger roll of 1 frame band, its main feature produces the narrow coils of hot-rolled steel of deformation temperature range, but because milling train quantity is more, cause production line length longer larger with investment.
(4) the steekle mill production line of Stand Mill tandem layout pattern is Stand Mill four roller reversible steekle mill, its main feature produces hot-rolled carbon steel coil of strip, this is because Stand Mill tandem layout pattern does not configure roughing and finish rolling region separately, in order to ensure the maximum muzzle velocity of milling train, make the specified roll torque of milling train less.And the drafts of roughing is larger under normal circumstances, need larger roll torque, the billeting capacity that therefore result in this layout pattern is more weak, thus roughing passage is increased, can not entry temperature at finishing be ensured, not be suitable for the coil of strip that rolling is narrow compared with Thin Specs deformation temperature range.
