430 stainless steel is one of the earliest development of ferritic stainless steel, mainly used in automotive, home appliances and other industries. After the cold-rolled 430 stainless steel plate contains a large number of defects can not be directly used, need to be softened by recrystallization annealing.

At present, the annealing of 430 ferritic stainless steel cold rolled sheet is divided into low temperature hood type annealing and high temperature continuous annealing. High temperature continuous annealing due to low energy consumption, short production cycle and other advantages become the main cold-rolled plate annealing process.

However, due to the high annealing temperature during continuous annealing, it is necessary to precisely control the entire annealing process.
