Embodiment Construction
[0030] The invention is further described below in conjunction with preferred embodiments:
[0031] combine figure 1 , figure 2 The basement is excavated under the hot-rolled coil warehouse, and the basement is used as a ventilated interlayer structure. First-level fans 3 are installed at both ends of the basement; air intake shutters 1 are installed on the workshop wall of the hot-rolled coil warehouse, and the outdoor air enters the storage and storage space through the air intake shutters. The air inlet chamber 8 and the filter 2 at the bottom of the air inlet chamber for buffering the air volume are sent into the underground ventilation interlayer 9 structure through the primary fan. The top of the basement corresponds to the two ends of the stacking position of the hot-rolled coils 6, and the secondary fans 4 are arranged, that is, the entire basement is not only an equipment room, but also a passage for air flow. The upper part of the secondary fan 4 is provided with...

The invention discloses a ventilating and cooling device and a cooling method of a hot-rolled coil yard machine, relating to the technical field of high temperature material cooling in steel and nonferrous metal processing industries. The cooling method comprises the following steps that: a step that the ventilating and cooling device arranged in a hot-rolled coil yard is used for cooling ahot-rolled coil stored in the hot-rolled coil yard, so that the temperature of the hot-rolled coil for the next working procedure is rapidly reduced to a target temperature, wherein the step is specifically to supply outdoor air into an underground ventilation sandwich structure through a primary air supply system; a step that the air in the underground ventilation sandwich structure is extracted through a secondary air supply system, accelerated to a speed required for cooling the hot-rolled coil, and then jetted to the end part of the hot-rolled coil by means of an air outlet; and a step that the air in a workshop of the hot-rolled coil yard is recycled so that the air enters the underground ventilation sandwich structure. The ventilating and cooling device of the hot-rolled coil yard machine disclosed by the invention can improve the hot-rolled coil cooling speed, and the cooling method can be more conveniently implemented.
Description
technical field [0001] The invention relates to the technical field of cooling high-temperature materials in the steel and non-ferrous metal processing industries, in particular to a ventilation cooling device and a cooling method for accelerating the cooling rate of hot-rolled coils. Background technique [0002] With the continuous construction of large-scale copper and aluminum sheet and strip processing plants in the domestic non-ferrous metal processing industry, in order to improve product quality, more and more companies are producing by hot-rolling technology, and the weight of a single hot-rolled coil is also increasing. Since the temperature of the hot-rolled coil is still as high as 300°C when the rolling is completed, and the next process requires that the temperature of the hot-rolled coil cannot be higher than a certain temperature, it is necessary to provide a cooling place for the hot-rolled coil. It is the hot-rolled coil warehouse. However, due to the high...
