How to effectively solve the error of numerical control equipment in p355gh equivalent cutting

07MnNiMoDR plate is a quenched and tempered high-strength steel plate for pressure vessels. P355GH equivalent, 07MnNiMoDR steel is mainly used in the construction of large-scale oil storage tanks, large spherical tanks and oil production platforms. At the same time, material 07MnNiMoDR is widely used in high-end technical fields such as petroleum, chemical industry, power station, boiler and so on. It can also be used for high-tech products such as reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, etc.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the p355gh equivalent plate should be derusted before cutting.

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product p355gh equivalent annual capacity is 200 thousand tons.
