Abstract
The invention discloses a horizontal annealing furnace heating section structure. The horizontal annealing furnace heating section structure comprises a furnace body, wherein one side of the furnace body is connected with a preheating section, and the other side of the furnace body is connected with a connection section; a plurality of groups of furnace rollers which are identical in height are arranged in the furnace body, and a steel band is supported by the furnace rollers; the upper side and the lower side of each furnace roller are respectively provided with a nozzle group consisting of a plurality of nozzles, each nozzle comprises a spraying pipe which is horizontally arranged, a spraying opening is formed in each spraying pipe, and the spraying pipes of each group of nozzles are parallel to one another; the nozzle groups at two sides of the furnace rollers are arranged at intervals; and each upper nozzle group and each lower nozzle group form a combustion area. The horizontal annealing furnace heating section structure has advantages that since the nozzle groups are arranged at intervals, during the heating process of a metal, crystal grains generated when the internal metallic tissue is changed are relatively uniform, so that the mechanical performance of strip steel can be improved, and the surface quality of the strip steel is also improved; and the heating section is designed in a sectional manner, so that the steel strip can be uniformly heated, the temperature of a strip steel plate can be adjusted by controlling the production speed and the temperature inside the furnace, the continuous full-load production of a unit is realized, and the production efficiency is improved.
Description
Technical field
The present invention relates to technical field of mechanical equipment, is a kind of annealing furnace heating zone structure specifically.
Background technology
In stainless steel strip production process, need to carry out anneal.Band steel after annealing furnace heating needs to be cooled by air cooling section, and existing air cooling segment structure is comparatively simple, does not consider that thermograde in stove and the type of cooling are on the impact of band steel, therefore, impact the performance of stainless steel strip.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of annealing furnace heating zone structure, not only structure is simple, and has considered thermograde and type of heating to the impact of band steel, and concrete technical scheme is as follows:
A kind of Horizental annealer heating zone structure, comprise body of heater, described body of heater side is connected with preheating section, and side is connected with linkage section in addition; Arrange many groups furnace roller of sustained height in described body of heater, steel band is held up by furnace roller; The both sides up and down of furnace roller all arrange the burner group of multiple burner composition, and described burner comprises horizontally disposed jet pipe, and described jet pipe arranges spout, and the jet pipe often organizing burner is parallel to each other; The burner group interval of furnace roller both sides is arranged; Each upper and lower burner group forms a combustion zone, is followed successively by 1-7 district from preheating section to linkage section, also arranges change of current fan at the top in 7th district.
Arrange cooling structure in described furnace roller, described cooling structure comprises the circulation line in furnace roller, and described circulation line is connected with the water coolant outside body of heater.
Advantage of the present invention is: because burner group interval is arranged, therefore, directly be heated and the radiation interval mode of being heated with becoming by hot mode of steel, change single by hot mode, as the tailored radiation type of heating of the single direct heating of existing combustion gas annealing furnace or electric furnace, metal is in thermal histories, the crystal grain generated when inside metallographic undergoes phase transition is relatively uniform, therefore, it is possible to improve the mechanical property of band steel, the surface quality of band steel is also improved; In addition, 1st to 4 district is laser heating district, and 5th to 7 district are heat preservation zone, gas stream in the stove is flowed to 1 direction, district by 7th district, make in-furnace temperature be that uniform gradient increases, band steel can reach rapidly the target temperature of annealing after preheating section in heating zone temperature, realize the continuous seepage of roll bending.The heating zone zoning design of this horizontal chamber oven, not only to band steel homogeneous heating, can also pass through production control travelling speed and in-furnace temperature accommodation zone steel plate temperature, thus realize the continuous full production of unit, enhance productivity.
