技术领域：Technical field:
本发明涉及热轧无缝钢管生产技术领域，尤其涉及一种针对控制冷却工艺处理后的热轧无缝钢管，清除管内残余水和氧化铁皮的气吹装置。The invention relates to the technical field of production of hot-rolled seamless steel pipes, in particular to an air blowing device for removing residual water and iron oxide scales in the pipes for hot-rolled seamless steel pipes treated by a controlled cooling process.
背景技术：Background technique:
在热轧无缝钢管控制冷却工艺生产过程中，由于管材特殊的环形界面特征，冷却水易于进入并滞留在钢管内部，这些管内残余水以及生成的氧化铁皮会对钢管的冷却产生不良影响，导致冷却不均匀，影响钢管产品质量。为了避免工艺上的残留冷却水及氧化铁皮所造成的影响，有必要在钢管出冷却区后，增加清除管内残余水和氧化铁皮的气吹装置，现有的一种气吹装置，布置在冷却辊道之间，由于冷却辊道之间的空间有限，当经过控制冷却后的钢管在其上通过，所述气吹装置难免会与钢管接触甚至相撞，从而破坏钢管的整体结构，影响最终产品的性能。During the production process of the hot-rolled seamless steel pipe controlled cooling process, due to the special annular interface characteristics of the pipe, the cooling water is easy to enter and stay inside the steel pipe. Uneven cooling affects the quality of steel pipe products. In order to avoid the influence caused by residual cooling water and scale in the process, it is necessary to add an air blowing device to remove residual water and scale in the pipe after the steel pipe leaves the cooling zone. An existing air blowing device is arranged in the cooling zone. Between the roller tables, due to the limited space between the cooling roller tables, when the controlled cooled steel pipe passes over it, the air blowing device will inevitably contact or even collide with the steel pipe, thereby destroying the overall structure of the steel pipe and affecting the final Product performance.
