The use and composition of ladle purging plug

 In modern steel smelting technology, ladle purging plug is a very important functional element in the out-of-furnace refining technology. Inert gases such as argon are introduced into the molten steel through the ladle purging plug at the bottom of the ladle to provide power for the stirring of the molten steel to achieve uniform steel. Aim to make the alloy composition and uniform temperature are average in the liquid steel. According to the assembly mode, the purging plug can be divided into integrated purging plug and seperated purging plug. Both are composed of purging plug core and well block. Whether integrated purging plug or seperated purging plug, the function of the well block is to protect the brick core and prevent molten steel from corroding to any position of the brick core except the working surface. Usually the bricks will be damaged as follows: Erosion of molten steel, spalling, transversely broken, longitudinally cracked of well block.
