Abstract
The utility model relates to a water cooler for hot-rolled rods, which belongs to the technical field of rolling production equipment and is used for increasing the cooling efficiency, reducing the length of a cooling line and the investment on water supply system equipment, saving energy and reducing consumption. The technical scheme of the utility model is as follows: each cooler of a positive flushing section comprises a front cooler water intake chamber and a rear cooler water intake chamber, both ends of each cooler water intake chamber are provided with an inlet duct and an outlet duct, and a communicating conduit is connected between the two cooler water intake chambers; a circular gap formed between the inlet duct and the outlet duct on both ends of the front cooler water intake chamber is at a small jet angle of less than 8 degrees, and a circular gap formed between the inlet duct and the outlet duct of the rear cooler water intake chamber is at a large jet angle of more than 20 degrees. When the pressure of water supply is 1.6MPa, the water pressure between the two water intake chambers of each cooler can reach more than 0.8MPa, the water flow in the tube is in a high-pressure turbulence state, and thereby the cooling effect and the water utilization efficiency are remarkably increased.
Description
Technical field
The utility model relates to controlled rolling and the passing water cooler of controlling the cooling use in a kind of hot rolled rod production, belongs to steel rolling production equipment technical field.
Background technology
The online water cooling of wearing is hot rolled rod control and the effective means of adjusting properties of product.Usually straight pipe type is worn every section cooler of water-cooling apparatus square impact section and is a water supply point, because water inlet circumferential weld area is much smaller than the cooling tube cross section, hydraulic pressure is decayed fast in the pipe, and cooling effect decreases.On the production line of wearing waterline length and water system limited ability, use this cooler and be unfavorable for control and adjust properties of product, be necessary to be improved.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly significantly improves cooling effectiveness, reduce to cool off line length and water system equipment investment, energy-saving and cost-reducing hot rolled rod passing water cooler.
The technical scheme that solves the problems of the technologies described above is:
A kind of hot rolled rod passing water cooler, every section cooler of square impact section is made up of former and later two cooler intake chambers, and there are inlet ducts and delivery channel in each cooler intake chamber two ends, is connected by connecting pipe between two cooling intake chambers.
Above-mentioned hot rolled rod passing water cooler, the circumferential weld that forms between the inlet ducts at described previous cooler intake chamber two ends and the delivery channel is the less spray angle below 8 °, and the circumferential weld that forms between the inlet ducts of a back cooler intake chamber and the delivery channel is the big spray angle more than 20 °.
Above-mentioned hot rolled rod passing water cooler, the tapping pipe of anterior reverse horn mouth of cooler outlet mounting strap of back water machine and spilled water hole.
This hot rolled rod passing water cooler is when pressure of supply water 1.6MPa, and hydraulic pressure can reach more than the 0.8MPa between two water supply points of cooler, and in-pipe flow is the high pressure turbulent condition, has significantly improved cooling effect.Can cool off φ 40mm bar with this cooler 10m water-cooled section, can cool off φ 12mm bar, the rolled piece recovery temperature is reached below 650 ℃ with 4m water-cooled section.Can significantly improve the utilization ratio of water, save the water yield more than 20%, save cooling line length and equipment investment than ordinary straight tubular type cooler, energy-saving and cost-reducing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the anterior cooler outlet schematic diagram of back water machine of the present utility model.
Mark is as follows among the figure: preceding cooler intake chamber inlet ducts 1, preceding cooler intake chamber 2, locking nut 3, preceding cooler intake chamber delivery channel 4, outlet tube head 5, import tube head 6, aftercooler intake chamber inlet ducts 7, aftercooler intake chamber 8, aftercooler intake chamber delivery channel 9, tapping pipe 10.
The specific embodiment
Referring to Fig. 1,2, the utility model is made up of preceding cooler intake chamber inlet ducts 1, preceding cooler intake chamber 2, locking nut 3, preceding cooler intake chamber delivery channel 4, outlet tube head 5, import tube head 6, aftercooler intake chamber inlet ducts 7, aftercooler intake chamber 8, aftercooler intake chamber delivery channel 9.
Cooler intake chamber 2 two ends before preceding cooler intake chamber inlet ducts 1 and preceding cooler intake chamber delivery channel 4 are connected, and by locking nut 3 lockings.Aftercooler intake chamber inlet ducts 7 and aftercooler intake chamber delivery channel 9 are connected aftercooler intake chamber 8 two ends, and by locking nut 3 lockings.
Be connected with import tube head 6 by outlet tube head 5 between preceding cooler intake chamber delivery channel 4 and the aftercooler intake chamber inlet ducts 7, outlet tube head 5 forms tapering with import tube head 6 by the screw thread advance and retreat and is connected.
The circumferential weld that forms between preceding cooler intake chamber inlet ducts 1 and the preceding cooler intake chamber delivery channel 4 adopts the shallow angle degree below 8 °.The circumferential weld that forms between aftercooler intake chamber inlet ducts 7 and the aftercooler intake chamber delivery channel 9 adopts the big spray angle more than 20 °.
This cooler installation adjusting method: at first preceding cooler intake chamber delivery channel 4 and outlet tube head 5 are screwed, aftercooler intake chamber inlet ducts 7 and import tube head 6 are screwed, then with the installation respectively of front and back two parts, centering, fixing, rotary outlet tube head 5 makes it to form tapering with import tube head 6 and is connected respectively afterwards.
The tapping pipe 10 of anterior reverse horn mouth of cooler outlet mounting strap of back water machine and spilled water hole, recoil water is pooled in the reverse horn mouth, and will just wash by water releases fully along horn mouth and spilled water hole.
Dispose cooler caliber and quantity, set each cooler front and back water supply point circumferential weld according to the cooling workpiece measurement, rolled piece is by 2 water supply coolers, last group outlet is finished and is efficiently worn the water cooling process for tapping pipe 10, back water machine, drier with reverse horn mouth and spilled water hole.
When pressure of supply water 1.6MPa, hydraulic pressure can reach more than the 0.8MPa between two water supply points of cooler, and in-pipe flow is the high pressure turbulent condition, has significantly improved cooling effectiveness.Simultaneously, the reasonable coupling by two kinds of spray angles of cooler can guarantee the motive force that rolled piece is enough, avoids the steel-fastening fault.On the production line of bar of 800,000 tons/year of production capacity, can cool off φ 40mm bar with this cooler 10m water-cooled section, can cool off φ 12mm bar with 4m water-cooled section, the rolled piece recovery temperature is reached below 650 ℃.Guaranteeing to have significantly improved the utilization ratio of water under the rolling direct motion prerequisite, can save the water yield more than 20% than ordinary straight tubular type cooler, saved cooling line length and water system equipment investment, energy-saving and cost-reducing.
