A537 Class 1 vessel plate surface treatment details

A537 Class 1 vessel plate surface treatment details

This article will mainly explain the deformation control and A537 CLASS 1 vessel plate surface treatment details of hot cutting, combined with many years of experience in processing A537 Class 1 vessel plate, katalor puts forward some control techniques and measures, hoping to give some help and reference to the majority of users and enterprises.

1. Control of thermal deformation
In the actual cutting process of NC cutting machine, due to the uneven heating and cooling of A537 Class 1 vessel plate, the internal stress of A537 Class 1 vessel plate will cause the workpiece to be cut to bend or displace in varying degrees. That is, cutting thermal deformation, the specific performance is shape distortion and cutting size deviation. Since the internal stress of A537 Class 1 vessel plate can not be balanced and completely eliminated, only some measures can be taken to reduce the thermal deformation.

2. Surface treatment of A537 Class 1 vessel plate
Usually the A537 Class 1 vessel plate from the steel plant go through a series of intermediate links to the cutting workshop, in this period of time, A537 Class 1 vessel plate surface inevitably produces a deposition of oxide. In addition, the A537 Class 1 vessel plate also produces an oxide coating attached to the surface of the A537 Class 1 vessel plate during rolling. These oxide scales have high melting point, are not easy to burn and melt, increase the preheating time, reduce the cutting speed. At the same time, after heating, the oxide scales splash everywhere, it is very easy to cause blockage to the cutting nozzle of NC cutting machine, reduce the service life of the cutting nozzle. So before cutting, it is necessary to do surface rust removal pretreatment for the A537 Class 1 vessel plate.

3. Surface treatment and method before cutting of A537 Class 1 vessel plate
Commonly used surface treatment and method before cutting of A537 Class 1 vessel plate is sand blasting, then painting for rust prevention.

In a word, the pre-treatment of rust removing and spraying paint before cutting A537 Class 1 vessel plate has become an indispensable link in the production of A537 Class 1 vessel plate cutting pieces.Hot cutting of A537 Class 1 vessel plate often causes thermal deformation. But in industrial production application, this kind of deformation effect is not completely eliminated, but control and preventive measures are taken to reduce the deformation effect caused by hot cutting.
