Abstract
The utility model discloses a cover-typed annealing furnace, which is used for metal coiled materials. The utility model has a central heating structure. The inner ring of a metal coil is provided with a central heater; the central heater is inserted into the central heating barrel of an inner cover through the top cover center of a heating cover. The utility model has other structure that the central heater is formed by the insertion of the lower part of a furnace into the inner ring of the metal coil; a central heating barrel is arranged outside the central heater; the central heating barrel is fixed on a furnace seat. The utility model has the advantages that except the outer ring of the metal coil is heated by the heat radiation of the inner cover, the central heater also makes the inner ring of the metal coil be heated at the same time in the process of annealing. The inner temperature and the outer temperature of the metal coil are even. Besides, the annealing period is shortened; the product yield and the product quality of the utility model are relatively improved.
Description
The utility model relates to a kind of bell type annealing furnace, belongs to the metal coiled material annealing bell type annealing furnace with center heating arrangement.
The bell type annealing furnace that is used for metal coiled material on producing at present generally is made up of heating mantles, inner cover, stove seat etc.Heater is set on the heating mantles, is generally electric heater or combustion heater.For preventing metal coiled material surface oxidation in annealing process, with inner cover and the sealing of stove seat, in fill protective gas N
2And H
2The stove seat is arranged with circulating fan, and the protective gas in the inner cover is flowed.During annealing; by the heat that is arranged on the heater fed on the heating mantles; heat radiation by inner cover comes the heating of metal coiled material; blower fan circulates the protective gas in the inner cover; convection heat transfer' heat-transfer by convection is strengthened in slit between metal coiled material and convection current plate; improve firing rate, and make every effort to about the even metal coiled material, inside and outside temperature.Owing to only depend on radiation and forced convertion to heat from outside to inside, make the annealing cycle long, furnace output is low, and the thermal efficiency is not high, and energy consumption increases, and metal coiled material radial temperature inequality makes the head and the tail temperature difference of metal coiled material bigger.
The purpose of this utility model provides a kind of bell type annealing furnace that can heat simultaneously metal coiled material inner ring and outer ring.
The utility model task is achieved in that the metal coiled material of being made up of heating mantles, outer heater, inner cover, stove seat, blower fan, convection current plate heats bell type annealing furnace with the center, is provided with central heater at the metallic coil inner ring.Central heater has two kinds of structures, a kind of structure is that inner cover seals a side by two concentric drums and connects into the end socket shape again, coiled material is covered on the inside, central heater is inserted in the thermotank of inner cover center by heating mantles top cover center, the center cartridge heater is closed, directly adds the thermal center (-tre) thermotank, and the center thermotank inserts the metallic coil inner ring by top, through radiant heat transfer, import heat into metal coiled material from inside to outside.
Another kind of structure is that central heater is placed the metal coiled material inner ring by lower furnace, and directly the heating of metal coiled material is provided with the center cartridge heater that is fixed on the stove seat outside the central heater, and the center cartridge heater is closed.
The utility model has the advantages that, in annealing process except that the inner cover heat radiation in metal coiled material outer ring heating, central heater also is heated the metal coiled material inner ring simultaneously, heat transmits from inside to outside, can fully be absorbed by metal coiled material, has reduced heat loss to greatest extent, the thermal efficiency is greatly improved, the metal coiled material internal and external temperature is even, has shortened the annealing cycle, and product yield and quality are all corresponding to be improved.
Fig. 1 is the section of structure of coiled material center heating bell type annealing furnace.
Fig. 2 is the section of structure of another kind of coiled material center heating bell type annealing furnace.
Embodiment 1:
See Fig. 1, present embodiment is a central heater by the stove top structure of packing into.Central heater 5 is the water-cooled gas gun, inner cover 2 is inserted at top cover 12 centers by heating mantles 1, inner cover seals a side by two concentric drums and connects into the end socket shape again, coiled material is covered on the inside, central heater 5 is inserted in the center thermotank 6 of inner cover by heating mantles top cover 12 centers, center cartridge heater 6 is closed, central heater can move up and down along the stove axis, directly add thermal center (-tre) thermotank 6, heat imports metal coiled material 4 inner rings through center thermotank 6 into by heat radiation, and heat transmits from inside to outside.Outer heater is a fuel burner nozzle 8, is installed on heating mantles 1 wall, and flame heat inner cover 2, inner cover 2 import heat into metal coiled material 4 outer rings through radiant heat transfer, and the heat ecto-entad transmits.Be arranged at circulating fan 7 under the stove seat 9 and drive flow through slit between metal coiled material 4 and the convection current plate 3 of circulation protective gas, reinforcement convection heat transfer' heat-transfer by convection, and uniform temperature.During discharging, extract central heater out, but the heating mantles top cover 12 of slinging successively, just discharging of heating inner cover 2.
Embodiment 2:
See Fig. 2, present embodiment is a central heater by the lower furnace structure of packing into.Central heater 5 is an electric heater, places metal coiled material 4 inner rings, and heat transmits in metal coiled material 4 from inside to outside, is covered with center cartridge heater 10 in the central heater outside, and the center cartridge heater is closed, and center cartridge heater 6 is fixed on the stove seat 7.Outer heater 8 is an electric heater, is installed on heating mantles 1 wall, and heating inner cover 11 covers on above the coiled material, and the ground runners is in furnace bottom.All the other are with embodiment 1.
