Description
Technical Field
The invention relates to a cooling device, in particular to a through water cooling device for bar production.
Background
The bar material is usually deformed steel bar and round steel bar, and is delivered in a straight bar shape, the size range of the small bar material specified by the national standard is 6-50 mm in diameter, and the length of the small bar material is 6-12 m in length, and the bar material is called wire material if being delivered in a coiled manner. The rod and the wire belong to the section steel with simple section, and the rolling process is very similar. The water cooling device is an indispensable important component on a modern bar and wire production line, is arranged between rolling mills or behind a finishing mill and is respectively used for controlling the temperature of a rolled piece in the rolling process and the cooling temperature of a finished product, thereby achieving the purpose of improving the performance of the product. On the old-fashioned stick wire rod production line, because do not reserve the position of water cooling device, so only can produce low-grade product or improve product mechanical properties through adding the alloy element, do not possess market competition advantage. The water cooling can improve the performance of the bar and can replace the functions of certain alloy elements in steel, so that the production cost can be reduced, and meanwhile, due to the improvement of the performance, the same building structure can use less steel, so that the requirement of the low-carbon era is met, and the water cooling has wide application prospect.
At present, on a hot-rolled bar and wire production line, in order to improve the performance of reinforcing steel bars, a water cooling device is generally adopted on the production line, and a rolled finished product is cooled to improve the mechanical property of the finished product. In order to ensure the water quality of the water for cooling the water, most of water supply and return systems for cooling the water on a production line are separated from turbid circulating water of the rolling mill, namely the water for cooling the water is supplied to an independent water supply pump. The temperature of the finished product steel product through water is generally about 900 ℃, and the following problems exist in the production process:
1) fine iron scales are easily generated in the water cooling process, the iron scales directly fall into a water return pool of the water cooling, the water quality of water of the water cooling is influenced, treatment facilities for subsequent water treatment are added, and the whole water cooling generates a large amount of steam which needs to be treated in a relatively closed space, so that a water tank which can be closed and can treat the water quality is needed;
2) the bar is conveyed and cooled on line, and a water system is separated independently, so that in the using process, the common method is to directly adopt spraying, and the cooling mode is rough in temperature control and difficult to accurately control;
3) the rod material is very heavy, and a conveying roller is required to be adopted for conveying when water passes through for cooling, but water is easy to enter due to spraying and the like in the traditional structure of the conveying roller, and the rod material is easy to corrode due to the sealing requirement of a water tank, transmission combination is not needed for a period of time, and the metal is corroded by water vapor generated in the cooling process, so that the waterproof treatment of the conveying roller is very necessary;
4) the temperature of the bar is about 900 ℃, a large amount of high-temperature steam can be generated in the spray cooling process, and in the production process, high-temperature steam is needed in some places, and if the high-temperature steam is directly discharged, the high-temperature steam is very wasted, and the conventional through-water cooling rotating shaft is not arranged in the aspect;
5) the surface of the bar is still provided with a large amount of vapor or even water stain after the bar passes through the water cooling device, after the bar is cooled by the water cooling device, the heat of the core cannot be completely cooled at once, and meanwhile, the temperature of the steel reaches about 550-650 ℃ after the heat of the part is transferred out for self tempering, the water stain on the surface can generate steam, fog occurs on the site of a production space, and the production is not facilitated.
