Thermal treatment is to improve one of means of ferrous materials performance, comprises several heat treatment process such as normalizing, quenching, tempering, annealing.Along with science and technology and industrial expansion, ferrous materials is had higher requirement, as higher intensity, high temperature resistance, high pressure, low temperature, corrosion-resistant, wearing and tearing and tissue, performance homogeneity.And then, steel plate heat treatment furnace is proposed to more strict requirement, as Control for Kiln Temperature precision ± 5 ℃, temperature uniformity ± 5 ℃, steel plate heating uniformity ± 2.5 ℃ etc.
At present, in large-scale steel plate hot treatment plant, for realizing continuously, high yield, the thermal treatment of steel plate all adopts the continuous heat treating furnace of carrying by roller-way to carry out realizing after the batch laser heating of steel plate.For normalizing, the quench treatment process of steel plate, no matter furnace temperature, between 900 ~ 1000 ℃, adopts radiator tube indirect heating still to use open flame combustion nozzle direct heating, and the index requests such as Control for Kiln Temperature precision, temperature uniformity, steel plate heating uniformity are easily realized; But, for temper process, particularly in, low-temperaturetempering, furnace temperature is between 200 ~ 400 ℃, this low temperature, the operating mode that control accuracy is high, uniformity requirement is strict, be difficult to realize in continuous roller bottom type heat treatment furnace.For this reason, for realizing the low temperature heat-treatment process of steel plate, generally adopted car-type heat treating furnace, carried out low-temperature heat, but can only steply produce by passing into the controlled hot gas of temperature, yielded poorly, steel plate is yielding.
Therefore, in the urgent need to a kind of Strip heating unit is provided, strict Control for Kiln Temperature precision, temperature uniformity, the requirement of steel plate heating uniformity in the time of can meeting subzero treatment.
Summary of the invention
The present invention is directed to the defect that heat treatment technics of the prior art cannot meet temperature uniformity, the requirement of steel plate heating uniformity, provide a kind of by even furnace temperature the Strip circulating heater to steel plate homogeneous heating.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of Strip circulating heater is provided, and this device, for whole box-structure, comprises air duct at top, two sidepiece air channels, some spray boxs, recirculation blower and some heating units;
Two sidepiece air channels are connected with air duct at top, and spray box is installed between two sidepiece air channels;
Recirculation blower is vertically mounted in air duct at top, and heating unit, through air duct at top, is installed in two sidepiece air channels.
In Strip circulating heater of the present invention, air duct at top inside is provided with flow deflector, the heating unit place that recirculating air is evenly led in air channel, both sides.
In Strip circulating heater of the present invention, the passage longitudinal section of spray box is symmetrical wedge shape along steel plate or with steel medullary ray, and the spout of spray box is gap spout or intensive circular hole spout.
In Strip circulating heater of the present invention, gapped between spray box and spray box, the gas that this gap permission is sprayed by spray box is turned back after running into sheet material or band steel, overflows to the spray box back side.
The beneficial effect that enforcement the present invention produces is: the present invention heats furnace gas by employing heating unit, then by furnace gas, is heated the indirect heating mode of steel plate, and than direct heating mode, furnace temperature, temperature uniformity are more easily controlled; Circulating heater is whole box-structure, and its sound construction, simple, compact, can be placed in process furnace by integral body.

Embodiment
For the effect that makes constitutional features of the present invention and reach has a better understanding and awareness, spy is by preferred embodiment and coordinate detailed explanation, is described as follows:
Embodiment of the present invention Strip circulating heater, as shown in Figure 1, this device is for whole box-structure, comprises air duct at top 1, two sidepiece air channels 2, some spray boxs 3, recirculation blower 9 and some heating units 8.Device is designed to whole box-structure, makes sound construction, simple, compact, can be placed in process furnace by integral body.
Two sidepiece air channels 2 are connected with air duct at top 1, and spray box 3 is installed between two sidepiece air channels 2;
Recirculation blower 9 is vertically mounted in air duct at top 1, and heating unit 8, through air duct at top 1, is installed in two sidepiece air channels 2.
As shown in Figure 1, in one embodiment of the present of invention, the casing center of top of Strip circulating heater is provided with a recirculation blower open holes 4, and both sides, top are provided with some heating unit open holess 5.This device inside is also provided with some flow deflectors 6, heating unit 8 places that recirculating air is evenly led in air channel, both sides 2.
In one embodiment of the present of invention, the passage longitudinal section of spray box 3 is symmetrical wedge shape along steel plate or with steel medullary ray, advantageously guarantees that spray box is along the homogeneity of steel plate or strip width direction jet, and then guarantees steel plate or band steel heating uniformity.
