Maintenance of large caliber rolling pipes

With the increasing use of large-diameter rolling pipes

Deal with the problem of decarburization on the surface of the honing pipe

Fang Gang is a kind of bar and is solid. In its production process,

Attention to the quality control of honing pipe

It is also necessary to pay attention to the following points

Improve the finish of the honing tube

A steel pipe generally obtained by honing process is called honing pipe.

Production characteristics of high precision cold drawn tube

Today we come to understand what are the characteristics of the production of cold drawn steel pipes.

Types of high precision cold drawn tubes

High-precision cold-drawn pipe is a kind of steel pipe

Points to note when rolling high precision cold drawn tubes

Because high-precision cold-drawn tubes have good mechanical properties

Improve the accuracy of the sizing standard of the rolled tube

Longitudinal rolling or cross rolling without small deformation of the mandrel on the rolling tube on the longitudinal rolling or cross rolling sizing machine

Factors causing surface problems of honing rolling tube

There are many people who do not pay much attention to the surface problems when choosing honing rollers.

Improve the surface roughness of honing cylinder tube

Cylinder, if its expression is 16 × 320, it means that the cylinder bore is 16 mm

Practicability of rolling tube

In fact, the work of the rolling tube is simple to reduce the surface roughness of the workpiece

Problems that often occur during quenching of cold drawn tubes

During the quenching heat treatment of the cold drawn tube
