In modern stainless steel coil production, annealing and pickling combined units are generally used for pre and post cold rolling treatment. Annealing and pickling are important processes in the production of stainless steel hot-rolled and cold-rolled coils. Their principles and processes play a very important guiding role in actual production. The selection of annealing equipment, pickling method and pickling conditions directly affect the final quality of stainless steel products.
Annealing process of stainless steel coil
Tropical annealing
The hardness of stainless steel coil increases after hot rolling, accompanied by carbide precipitation. The purpose of annealing stainless steel coils of different steel grades is different.
Solution treatment of austenitic stainless steel
Austenitic stainless steel will precipitate carbides after hot rolling, and the grains will deform with processing. The purpose of austenitic stainless steel annealing is to heat the steel to the annealing temperature (1010 ~ 1150 ℃), so that the precipitated carbides are fully dissolved in austenite at high temperature, and then quickly cooled (water-cooled quenching), so that the carbon dissolved in austenite remains at room temperature. At the same time, the grain size is adjusted during annealing to achieve the purpose of softening.
Due to the need for rapid cooling to prevent the re precipitation of carbides, the austenitic stainless steel coil after hot rolling can only be used in a continuous annealing furnace.
Annealing of ferritic and martensitic stainless steels
A certain amount of martensite will be produced during the cooling process of most ferritic stainless steel coils after hot rolling. The main purpose of annealing is to decompose martensite into ferrite and grain like or spherical carbides, so as to achieve the purpose of softening; In addition, annealing can also change the elongated grains into equiaxed grains during rolling.
Martensitic stainless steel coils are austenite at high temperature. Martensitic transformation occurs during cooling after hot rolling, and high hardness martensitic structure is obtained at room temperature. The purpose of annealing is to decompose this martensite into spherical carbides uniformly distributed on the ferrite matrix, so as to soften the steel.
The precipitation, aggregation and spheroidization of carbides during annealing of martensitic stainless steel coils and ferritic stainless steel coils take a long time, so the hot-rolled coils of this kind of stainless steel are usually annealed in bell type furnace. Of course, for single-phase ferritic steel without martensite after hot rolling, it is more reasonable to choose continuous furnace.
Cold strip annealing
Cold strip annealing of stainless steel coils can be divided into intermediate annealing and finished annealing.
The purpose of intermediate annealing is to eliminate the work hardening in the cold rolling process, so that the cold rolled stainless steel strip can be softened by recrystallization annealing for the next rolling process. The final annealing process is generally the same as the intermediate annealing, and individual products are subject to special treatment according to needs.
Continuous annealing furnace is used for cold strip annealing. Generally, horizontal cold strip annealing and pickling machine is used. For Ba plate, it needs to enter the bright annealing production line for treatment.
