Abstract
The utility model relates to a surface dephosphorization system for steel pipes. A dual-pipeline dual-ring adjustable manner is adopted; a large water spray ring and a small water spray ring are simultaneously mounted in the same dephosphorization box, and different rings are used when the steel pipes of different specifications are produced; and water is respectively supplied to dual pipelines of the large and the small rings by adopting a high pressure ball valve, and the large and the small water spray rings can be switched on site conveniently and rapidly, so the requirements of a production process are satisfied, the yield of the steel pipes is increased, the quality of the steel pipes is improved, the production cost is reduced, and the production efficiency is improved. The surface dephosphorization system is suitable for being used for dephosphorizing surfaces of the steel pipes 102mm to 222mm in diameter.
Description
Technical field
The utility model relates to a kind of superficial treatment system, especially a kind of steel tube surface descaling system.
Background technology
Seamless steel tube production is in the majority to Φ 222 steel pipes with Φ 102 at present; But steel tube surface quality is the bottleneck problem of producing all the time; The oxide layer of steel pipe steel tube surface in the de-scaling process is difficult for indivisible; Cause the steel pipe appearance that the spot and the pockmark of consecutive are arranged, article phase extreme difference has had a strong impact on steel tube surface quality.The spray ring of general design is less at present, and diameter has only 0.8 meter, 8 groups at nozzle; Injection degree 1.5 degree, projected area is not enough during to the steel tube surface de-scaling of Φ 102 to Φ 155, can not cover whole Zhi Gangguan appearance fully; Not right because of spray angle again, can not centering, cause the de-scaling waterline not connect; The middle gap that produces causes the steel pipe oxide layer residual indivisible.
Summary of the invention
The purpose of the utility model is that change descaling sprays ring spray angle is not right; Can not centering; Cause the unconnected drawback of de-scaling waterline, thereby design that a cover dual circuit dicyclo is adjustable, conversion is simple and convenient and do not influence the steel tube surface descaling system of rhythm of production and production specification.The technical scheme of the utility model is so to realize:
A kind of steel tube surface descaling system comprises the water ring of being located in the De-scaling box, high-pressure intake pipe that is connected with water ring and low pressure water inlet pipe; And divide and to be laid in Scale removing valve and the flashing valve on both, water ring is provided with two altogether, is respectively little water ring and big water ring; Both are connected by water pipe; Said water pipe is provided with high-pressure ball valve, and is connected with the low pressure water inlet pipe with high-pressure intake pipe through high-pressure ball valve, is equipped with the nozzle of annular configuration on said little water ring and the big water ring.
As preferably, nearly high-pressure ball valve place is provided with a check valve on the said low pressure water inlet pipe.
As preferably, the diameter of said little water ring is 1～1.1m, and its top nozzle is provided with 9～12 groups altogether, and spray angle is 4.8～5.3 degree; The diameter of said big water ring is 1.2～1.4m, and its top nozzle is provided with 13～17 groups altogether, and spray angle is 5.3～5.7 degree.
As preferably, the diameter of said little water ring is 1.05m, and its top nozzle is provided with 10 groups altogether, and spray angle is 5 degree; The diameter of said big water ring is 1.30m, and its top nozzle is provided with 15 groups altogether, and spray angle is 5.5 degree.
The steel tube surface descaling system of the utility model design adopts the dual circuit dicyclo adjustable, is installed in large and small water ring simultaneously in the same De-scaling box, produces different size and uses different rings; Adopt a high-pressure ball valve that large and small ring dual circuit is supplied water respectively, the large and small water ring of on-the-spot conversion is convenient and swift, makes and has not only satisfied manufacturing technique requirent, has improved steel pipe lumber recovery and quality, and has reduced production cost, has improved production efficiency.Be applicable to that Φ 102 uses to the surperficial de-scaling of Φ 222 steel pipes.
The workflow of the utility model is: flashing valve through automatically controlled signal open → water inlet of one-way valve opens → low pressure is full of pipeline; For high pressure water inlet de-scaling ready → Scale removing valve opens → flashing valve cuts out, closed check valve → high pressure water inlet is carried out de-scaling through the water ring nozzle to steel tube surface.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technical scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing, a kind of steel tube surface descaling system comprises the water ring of being located in the De-scaling box 7; The high-pressure intake pipe 8 and the low pressure water inlet pipe 9 that are connected with water ring, and divide the Scale removing valve 2 and flashing valve 1 that is laid on both, water ring is provided with two altogether; Be respectively little water ring 5 and big water ring 6, both are connected by water pipe 11, and the diameter of said little water ring 5 is 1.05m; Its top nozzle 10 is provided with 10 groups altogether, and spray angle is 5 degree; The diameter of said big water ring 6 is 1.30m, and its top nozzle 10 is provided with 15 groups altogether, and spray angle is 5.5 degree.
Said water pipe 11 is provided with high-pressure ball valve 4, and is connected with low pressure water inlet pipe 9 with high-pressure intake pipe 8 through high-pressure ball valve 4, is equipped with the nozzle 10 of annular configuration on said little water ring 5 and the big water ring 6.Nearly high-pressure ball valve 4 places are provided with a check valve 3 on the low pressure water inlet pipe 9.
When the steel pipe of producing Φ 102 to Φ 155 adopts diameter is 1.05 meters spray ring, is 1.30 meters spray ring when the steel pipe employing diameter of producing Φ 155 to Φ 222.
