The device of the present invention has the advantages of uniform and high speed cooling operation of the steel coil to improve product quality and increase production efficiency, simple structure, convenient maintenance, low investment and preferable economic benefit. The present invention is suitable for rebuilding old factories.
Description
The present invention relates to the auxiliary equipment of cold-strip steel, be applicable to placement and cooling after the heat treatment of cold-strip steel coil of strip is come out of the stove.
The coil of strip of flat cold-rolled sheet factory is after (the coil of strip tapping temperature is generally at 160～200 ℃) are come out of the stove in heat treatment both at home and abroad, must leave one in and place the place when treating that steel roll temperature is cooled to 40～45 ℃, can carry out the subsequent processing of flat cold-rolled sheet technology---smooth operation, the length of its cool time directly influences the production cycle, and the time of cooling is long more unfavorable more to producing.At present, both at home and abroad the heat treatment coil of strip methods for cooling of coming out of the stove is studied and inquired into, often adopt advanced upright buttress formula ventilation cooling device.It by cooling bench (1), be installed in motor fan (2) below the cooling bench (1) and the convection current plate (3) of middle ventilative similar car wheel structure is formed.Coil of strip (4) is vertical to be deposited on the cooling bench (1), can stack 3～4 coil of strips (4) on the cooling bench (1), separates with convection current plate (3) between the coil of strip (4).The advantage of this upright buttress formula ventilation cooling device is: 1. cooling velocity is fast.(4) are vertical is deposited on the cooling bench (1) for invar volume, and the motor fan below it (2) generally can shorten 2～3 days cool time than natural air cooling to coil of strip (4) internal diameter blowing cooling.2. cooling bench (1) amount of storage is bigger.Can place 3～4 coil of strips (4) on the cooling bench (1), its gross weight can reach 60～100 tons of weights.3. cooling is more even.Because of vertical placement, the internal diameter and the external diameter of coil of strip (4) are evenly cooled off.The problem of its existence is: 1. the investment of civil engineering cost is higher, complex structure, and difficulty of construction is big.2. the vertical installation of blower fan is fragile, and Maintenance and Repair are complicated.3. descend the step during smooth operation, 90 ° of coil of strip (4) upsets must be increased process links and man-hour.Therefore, general old factory is difficult to implement above-mentioned upright buttress formula ventilation cooling device technology.
The objective of the invention is to propose a kind of horizontal air cooling discharging apparatus for coiled steel for the problems referred to above that solve upright buttress formula ventilation cooling device existence.Its small investment, good cooling results.
Primary structure of the present invention is:
A kind of horizontal air cooling discharging apparatus for coiled steel is made up of motor fan, cooling bench, and characteristics are to adopt single hole formula to concentrate air-supply structure, i.e. motor fan (5), and---list is cheated cooling bench (8) to underground main air supply duct (6)---branch ajutage road (7)---; A plurality of single hole cooling benches (8) are arranged between two underground main air supply ducts (6) that are parallel to each other or (13) lining, the coil of strip of side hole equably; Single hole cooling bench (8) is by base plate (9), supports the cambered plate (11) of horizontally-arranged coil of strip (10), and forms in the face of two ventilating openings (12) in the branch ajutage road (7) of horizontally-arranged coil of strip (10) end face.Its another characteristics are strip ventilating openings that ventilating opening (12) is arranged horizontally.
The invention will be further described with an embodiment below.
Fig. 1 is the structural representation of upright buttress formula ventilation cooling device.
Fig. 2 is a kind of planar structure schematic diagram of horizontal air cooling discharging apparatus for coiled steel.
Fig. 3 is the main TV structure schematic diagram of single hole cooling bench of the present invention (8).
Fig. 4 is the structural representation along Fig. 3 A-A section of the present invention.
Fig. 5 is the structural representation along Fig. 3 B-B section of the present invention.
A kind of horizontal coil of strip ventilation cooling device is made up of motor fan, cooling bench, its feature is to adopt single hole formula to concentrate air-supply structure, promptly, pass through the branch ajutage road (7) of main air supply duct (6) both sides again wind is cheated cooling bench (8) to list by three underground main air supply ducts (6) air-supply of motor fan (5) by communicating with it; A plurality of single hole cooling benches (8) are arranged between two underground main air supply ducts (6) that are parallel to each other or (13) lining, the coil of strip of side hole equably; Single hole cooling bench (8) is by base plate (9), supports the cambered plate (11) of horizontally-arranged coil of strip (10), and two ventilating openings (12) of facing the branch ajutage road (7) of horizontally-arranged coil of strip (10) end face are formed, two base plates (9) are affixed with the lower end of cambered plate (11), and the upper end of cambered plate (11) is fixed on the civil engineering ground (14) at (13) place, coil of strip hole.
Its another characteristics are strip ventilating openings that ventilating opening (12) is arranged horizontally, and ventilating opening (12) is in the face of two end faces of the coil of strip (10) of horizontal placement.
Its last characteristic be have 6 motor fans (5) by 18 underground main air supply ducts (6) and corresponding minute the ajutage road (7) blow to 12 single hole cooling benches (8) of (13) lining, coil of strip hole, the direction of arrow flows to for air-supply, the length of its horizontally disposed ventilating opening (12) * wide is 400mm * 50mm, ventilating opening (12) is in the face of two end faces of horizontally-arranged coil of strip (10), and ventilating opening (12) is 125mm apart from the height h of base plate (9).
