Abstract
The invention provides a stainless steel strip bell type annealing furnace which comprises a furnace body (1). A high speed convection fan (2) is arranged at the bottom of the furnace body (1), the furnace body (1) is connected with an ammonia decomposition gas generator (4) through a delivery pipe (3), and the ammonia decomposition gas generator (4) is connected with an ammonia decomposition gas generation controller (5). In the stainless steel strip bell type annealing furnace, ammonia decomposition gas generated by the ammonia decomposition gas generator is transported into the furnace body by utilizing the delivery pipe as the protective gas of a stainless steel strip, thereby ensuring no oxidation phenomenon on the surface of the stainless steel strip and enabling a next pickling procedure to be easier to carry out; and meanwhile, the high speed convection fan is arranged at the bottom of the furnace body and fully carries out thermal convection in the furnace body, thereby enabling the temperature in the furnace body to be uniform and ensuring an annealing process to be normally finished. The consistency of the mechanical property of the stainless steel strip using the stainless steel strip bell type annealing furnace can be ensured.
Description
Technical field
The present invention relates to a kind of annealing furnace, particularly stainless steel strip bell type annealing furnace.
Background technology
Stainless steel belt is needing through anneal after the hot rolling and after cold rolling, and general at present employing box-type furnace carries out anneal.
Use box-type furnace that stainless steel belt is carried out anneal, exist annealing temperature inhomogeneous, owing to there is not shielding gas, the surface oxidation phenomenon of stainless steel belt is serious, thereby causes steel strip surface pit to occur, has a strong impact on the quality of stainless steel belt.
Summary of the invention
At above-mentioned defective; stainless steel strip bell type annealing furnace provided by the invention; adopt the decomposed ammonia body as shielding gas; thereby guarantee that the stainless steel belt surface does not have oxidative phenomena; make down that the road pickling process is easier to carry out; be provided with the high speed convection blower fan owing to bottom of furnace body simultaneously, thereby the intravital temperature of stove is very even, the mechanical property consistent performance of annealing back steel band accesses assurance.
Stainless steel strip bell type annealing furnace provided by the invention, comprise body of heater (1), the bottom of this body of heater (1) is provided with high speed convection blower fan (2), this body of heater (1) connects decomposed ammonia body producer (4) by transfer lime (3), and this decomposed ammonia body producer (4) connects ammonia and decomposes generator controller (5).
Stainless steel strip bell type annealing furnace provided by the invention; utilize transfer lime that the decomposed ammonia body that decomposed ammonia body producer produces is transported in the body of heater; make the shielding gas of decomposed ammonia body as stainless steel belt; thereby guarantee that the stainless steel belt surface does not have oxidative phenomena; make down that the road pickling process is easier to carry out; simultaneously the high speed convection blower fan is set at bottom of furnace body; the intravital thermal convection of stove is more abundant during the high speed convection blower fan; thereby make the intravital temperature of stove even; guarantee normally finishing of annealing process; use the mechanical property consistent performance of stainless steel strip bell type annealing furnace annealed stainless steel belt to access assurance, make down that the road pickling process is easier to carry out simultaneously.
