How to deal problems which we meet during processing satinelss steel pipes?

May,Fri,2022

Many problems will have when processing all stainless steel pipes. Because there are lots of stainless steel products, so I will introduce the problems which will appear during processing 304 stainless steel in detail. It will appear the surface crack, scare, has mixture and the other surface faults

 

  Appearing these faults is because that outer arc angle of subcutaneous plate appears broadwise crack, small impurity and crystallizer. These faults are not only decrease the quality of the surface of the stainless steel pipes and also affect the quality of the products. So it is improtant to prevent and dispose 304 satinless steel pipes surface faults.

  To prevent this situation, it is necessary to keep sector area. To prevent this situation, we forbid using over-year quipments. There is a little impurity in the crystallizer. We should examine the water in crystallizer regularly. We will reduce the weakening of the edge crack width of the stainless steel plate and the uneven deformation of the rolling edge of the wide and thick plate.

 

  To prevent the corner temperature going into the brittle zone duing casting billet, it is necessary to control the billet corner temperature which has different widths. To reduce the roll fittings inhomogeneous shape, we must improve the roll fittings pressure resistance, optimize billet hot techonlogy and decrease the temperature difference between upper and lower.

 

  It is necessary to improve the roll ability of the 304 stainlesss steel pipes forging billet, prevent local deep burning and clean up slag on the surface of cast slabs.
