Falling down the drilling process, this kind of uniform honing

The cylinder tube is processed by rolling.

Hot-rolled cylinder tubes are made by continuous casting of round tube slabs or preliminary rolled slabs,

The requirements for the processing technology of cylinder tubes are mainly processed by cold drawing and hot rolling.

Smaller outer diameter.

Improve surface roughness.

Cylinder tube is a kind of high-precision steel tube material after cold drawing or hot rolling.

Cold drawn seamless pipe often applied specifications

The cold drawn steel pipe plant was informed that the selection of cold drawn seamless pipe material is a chain factor that determines the quality of the product.

Fine cold-drawn pipe (fine-drawn pipe) is a kind of high-precision steel pipe data that uses cold-drawn pipe seamless pipe

The causes of insufficient hardness of the quenched workpiece are as follows.

Cold-rolled formed steel allows local buckling of the section, so that the bearing capacity of the bar after buckling can be fully utilized; while hot-rolled steel does not allow local buckling of the
