The hot metal desulfurization lance is a component of the hot metal desulfurization conveying desulfurization agent injection by the injection method.
The product is composed of an inner metal structure (a seamless steel pipe is placed in the middle, which is a channel for injecting the desulfurizing agent) and an outer layer of mullite corundum castable. It is produced by vibration casting method of a combination of a professional production line.
The product has the characteristics of many production processes and long production cycle, and has excellent performances such as corrosion resistance and thermal shock resistance in use.
