来源:/

【 发布于:2018-01-19 17:19:33 】


精密钢管是近几年出现的产品,主要是内孔、外壁尺寸有严格的公差及粗糙度。

The precision steel pipe is the product that has appeared in recent years. It is mainly the tolerance and roughness of the inner hole and the outer wall.

无缝钢管主要特点是无焊接缝,可承受较大的压力,产品可以是很粗糙的铸态或冷拨件。

The main feature of seamless steel pipe is no welding joint, it can bear large pressure, the product can be a very rough cast or cold dial.

冷拔精密钢管的特点:

The characteristics of cold - drawn precision steel pipe:

外径更小。精度高可做小批量生。冷拔成品精度高,表面质量好。钢管横面积更复杂。钢管性能更优越,金属比较密。

The outer diameter is smaller. High precision can be used as a small batch. The cold - drawn finished product has high precision and good surface quality. The cross area of steel pipe is more complex. The performance of the steel pipe is superior, and the metal is more dense.

无缝管

热轧精密钢管的特点:

Characteristics of hot rolled precision steel pipe:

热轧精密钢管用连铸圆管坯板坯或初轧板坯作原料,经步进式加热炉加热,高压水除鳞后进入粗轧机,粗轧料经切头、尾、再进入精轧机,实施计算机 控制轧制,终轧后即经过层流冷却和卷取机卷取、成为直发卷。直发卷的头、尾往往呈舌状及鱼尾状,厚度、 宽度精度较差,边部常存在浪形、折边、塔形等缺陷。

With the continuous casting round billet slab or steel tubeshot rolledprecision steel as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling and after rolling through the laminar cooling and coiling machine, coiling become straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects.
