Embodiment 1

[0031] The specific operation steps of the integrated circulating hot air flow air flotation heating plate strip method are as follows:

[0032] Fix the lower equalizing chamber 8, adjust the upper equalizing chamber 12 according to the size (thickness) of the plate and strip 3, ensure that the upper and lower equalizing chambers are parallel to each other, and obtain a suitable spacing of 20~40mm to form the heating chamber 9.

[0033] Start the upper heating unit 1 and the lower heating unit 14, the air outlet 6 of the fan passes through the air inlet 4 of the upper equalizing chamber and the air inlet 13 of the lower equalizing chamber and sends it into the upper and lower equalizing chambers 12 and 8. The nozzle unit 11 and the lower nozzle unit 16 are sprayed into the heating chamber 9, and the hot air in the heating chamber 9 is recycled to the air inlet 5 of the fan along the upper and lower return pipes 2 and 15 in the upper and lower two equalizing chambers 12 and 8, c...

Embodiment 2

[0040] The specific operation steps of the integrated circulating hot air flow air flotation heating plate strip method are as follows:

[0041] Fix the upper flow equalization chamber 12, adjust the lower flow equalization chamber 8 according to the size (thickness) of the plate and strip 3, ensure that the upper and lower flow equalization chambers are parallel to each other, and obtain a suitable distance of 20~40mm to form a heating chamber 9. All the other steps are the same as in Example 1.

Abstract

The invention relates to a device and method for integrated circulating hot airflow air flotation heating of a plate strip. After being heated and equalized by an upper flow equalizing bin and a lower flow equalizing bin, airflow input by a draught fan is directly jetted to the upper surface and the lower surface of the plate strip moving in a heating bin so as to heat the plate strip; and hot airflow below jacks up the plate strip stably till the plate strip is suspended in a proper height position in the heating bin. The draught fan is used for utilizing hot airflow in return pipelines in the flow equalizing bins circularly, and the effect of saving energy is achieved. According to the device and method, the structure is simple and compact, the stability and uniformity of air flotation heating of the plate strip can be effectively improved, and the characteristic that energy consumption is reduced is achieved.

Description

technical field [0001] The invention relates to an integrated circulating hot air flow air flotation heating plate strip device and method. Background technique [0002] The air-floating plate and strip heating method generally adopts a circulating fan, and the hot air is sent to the nozzle of the air cushion box through the air channel through the equalizing chamber, and the pressure difference of the gas formed by the upper and lower nozzles is used to float the plate and strip between the upper and lower nozzles. During this period, the gas in the lower part is like forming an air cushion, so that when the strip passes through the heating zone, there is no contact with foreign objects, so as to avoid scratching the surface, and the high-speed heat transfer method based on convection heat transfer heats the strip. This method is now widely used in the production technology of high-end aluminum strips, copper strips and ultra-thin physically tempered glass. However, the ex...
