Product Introduction

The long water port is a refractory material connecting the big package and the tundish. The long water port has the functions of stabilizing the flow state of molten steel, preventing the oxidation of molten steel and splashing of molten steel. Our company has successfully developed a high and medium grade baking-free long water mouth, which has the advantages of good thermal shock resistance, strong resistance to molten steel erosion, and good slag resistance. At the same time, because of its convenient operation, it can greatly improve the working conditions and can be rapidly popularized and applied.
