EN10155 S355J0W steel plate production process

At the end of blowing, the silicon content in the molten steel is very low. In order to meet the silicon content requirements of EN10155 S355J0W steel plate, a certain amount of silicon must be added in the form of alloy material. In addition to being used as a deoxidizer consumption part, it also increases silicon in molten steel. The silicon increase amount should be accurately calculated and not exceed the allowable range for blowing EN10155 S355J0W steel plate.

End point control: control to make the chemical composition and temperature of the metal meet the requirements of EN10155 S355J0W steel plate at the end of the blowing of oxygen converter. There are two methods to control the end point: carburizing method and pulling carburizing method.

Output: temperature and composition of EN10155 S355J0W steel plate meet the requirements of the steel type. Care should be taken to prevent molten slag from flowing into the ladle when drawing steel. Additives used to adjust the temperature, composition and deoxidation of molten steel are added to the ladle or flow during the drawing process.
