Abstract

The invention relates to horizontal bright annealing equipment for stainless steel. The equipment comprises an uncoiling section, a cleaning section, a process section, a flattening section and a coiling section which are sequentially arranged along the process flow direction, wherein i, a plurality of procedures such as the cleaning section, annealing and flattening are connected together to form a continuous unit, a 2B/BA surface stainless steel product is directly produced, the transportation of steel coils among the procedures is omitted, the yield is improved, and factory construction land and project investment are saved to a great extent; and meanwhile, productivity can be greatly improved, a stainless steel annealing-pickling unit can be comprehensively replaced, and the environmental protection problem is solved.

Description

technical field [0001] The invention relates to the field of stainless steel bright annealing, in particular to a stainless steel horizontal bright annealing equipment. Background technique [0002] The existing stainless steel cold-rolled annealing is generally realized by annealing pickling unit and bright annealing unit, but there are some problems. Annealing and pickling units have high production costs and high pollution problems; the current bright annealing units, whether they are vertical bright annealing units or horizontal bright annealing units, have extremely low production capacity. The large vertical bright annealing units are all single-pass heating annealing furnaces, with a production capacity of 60,000 to 80,000 tons per year, and most of the horizontal bright annealing units are 10,000 to 100,000 tons per year. Most of the horizontal bright annealing units in some existing stainless steel production plants have no degreasing section, no looper and no temp...
