Abstract
The utility model discloses a silicon steel annealing furnace. The silicon steel annealing furnace comprises a preheating chamber, a nonoxidation heating chamber, a radiant heating chamber, a radiant soaking chamber, a slowly cooling chamber, a quick cooling chamber and a wind cooling chamber which are sequentially arranged; a conveying mechanism is arranged in the length direction of the wind cooling chamber; a gas inlet system is arranged outside the wind cooling chamber; and an air box assembly which is communicated with the output end of the gas inlet system and wind outlet assemblies which are arranged in the length direction of the conveying mechanism side by side and communicated with the air box assembly are arranged inside the wind cooling chamber. The silicon steel annealing furnace solves the problems that the cooling effect of a water cooling roller is poor and edge waves or center waves of strip steel are generated; meanwhile, great improvement on the cooling capability can increase the running speed of a production line to 95 to 100 meters per minute; and a linear jetting tuyere ensures quick and uniform cooling of the whole plate surface of the strip steel.
Description
Technical field
The utility model relates to the steel heat processing technology field, is specifically related to a kind of silicon steel annealing furnace.
Background technology
Annealing process is the significant process of metal processing, it is that metal works slowly is heated to certain temperature, keep the enough time, then with the Reasonable Speed cooling, purpose is to reduce hardness, improve machinability, eliminate unrelieved stress, stable dimensions reduces distortion and crackle tendency, crystal grain thinning is eliminated tissue defects.
General non orientating silicon steel uses continuous annealing furnace that steel band is carried out anneal, so that steel band reaches desired electromagnetism and mechanical property.Traditional annealing furnace comprises preheating zone (PHS), nonoxidizing heating district (NOF), radiation heating district (RTHS), radiation soaking zone (RTSS), slow cooling zone (SJCS), rapid cooling zone (RJCS) successively, steel band normal temperature enters annealing furnace, through heating, soaking, cooling, its plate temperature is about 100 ℃ when coming out of the stove, since temperature too high easy influence next coating operation be coated with roller surface and coating quality, so still need the plate temperature be dropped to about 60 ℃ after silicon steel sheet is come out of the stove through the cooling effect of water cooled rolls.
Yet there is following defective in above-mentioned existing annealing furnace when processing silicon steel steel band:
One, in stove internal cooling district, cooling temperature and air quantity are inhomogeneous, will cause steel band plate face slight deformation, are specially limit wave or middle shape wave and become, and have a strong impact on the following process and the functional quality of silicon steel goods.
Two,, cause the limit wave or the middle shape wave of steel band plate face to change to obviously easily because the water cooled rolls inhomogeneous cooling is even.
Three, be subjected to the restriction of the cooling power of annealing furnace cooling zone and water cooled rolls, the production line travelling speed is subjected to severely restricts, generally can only move 80-85 rice/minute.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of silicon steel annealing furnace, can effectively enhance productivity, and can avoid the wave transformation of steel band.
For achieving the above object, the utility model adopts following technical scheme:
The silicon steel annealing furnace, comprise the preheating chamber, nonoxidizing heating chamber, radiation heating chamber, the equal hot cell of radiation, slow cooling room, quick cooling chamber and the air-cooling chamber that set gradually, be provided with a transfer mechanism along described air-cooling chamber length direction, the air-cooling chamber outer setting has inlet system, be provided with the bellow assemblies that is connected with the conducting of described inlet system output terminal in the air-cooling chamber, be arranged side by side and conducting is connected air outlet assembly on the described bellow assemblies along the length direction of described transfer mechanism.
Described bellow assemblies comprises the last bellows that are positioned at described transfer mechanism top, and the following bellows that are positioned at described transfer mechanism bottom, described air outlet assembly comprises a plurality of upper outlet wind that are arranged side by side at described transfer mechanism top and are connected with described upward bellows conducting, and a plurality of following air outlet that is arranged side by side at described transfer mechanism bottom and is connected with described bellows conducting down.
The outside of described air-cooling chamber also is connected with the exhaust system with its chamber conducting.
Described transfer mechanism comprises a plurality of carrying rollers that are arranged side by side along the air-cooling chamber length direction.
