Two methods for reducing ceramic tubes

Two methods for reducing ceramic tubes

During the process of reducing the diameter of the inner hole of ceramic pipes, the process method of changing the pipe diameter mainly includes pipe sinking and reducing the framework of the coreless rolling process of the pipe rolling mill. There are generally two methods.

Operation during tube heating.

1. Tube tension reducing machine:

The purpose of reducing the frame without mandrel and tension during the rolling process of hollow tube rolling mill is to obtain long pipes and small diameters to expand product specifications and improve unit production capacity. The tension free reducing machine and the longitudinal rolling sizing machine are the same, but the number of grinding frames is reduced by 15-22.

2. Tube tension reducing machine:

The continuous method of reducing the belt tension in the frame of the hollow tube mill without a core rod aims to obtain both reduced and reduced wall finished tubes. The tension reduces the total wall thickness variation by -30% to+30%, so some specifications of pipelines can be used to produce specifications through tension reducing steel pipe mills.

The second is low-temperature operation.

Tube cooling reduction:

The method of reducing the diameter of the tube at room temperature involves a similar heat dissipation process. When cold is the basic characteristic of reducing the stability and deformation of the workpiece cross-section, it is not easy to experience rolling and folding.
