Argon permeable brick at bottom of ladle

Detailed introduction

The gas permeable brick at the bottom of ladle is the core component of refining and post treatment. Oxygen is blown into the ladle through the permeable brick in the process of using, and the molten steel is stirred strongly. Its main function and purpose is to homogenize the composition of molten steel and the temperature of molten steel, and promote the inclusion to collide and float. The ladle bottom argon blown permeable brick produced by Tangshan Special Refractory Material Co., Ltd. has reasonable structure design, good thermal stability, erosion resistance, corrosion resistance and permeability resistance, high blowing rate, safe and reliable operation, long service life.
