Advanced Plasma Powder Overlay Technology for Copper Blast Furnace Tuyere Durability
Blast furnace tuyeres, crucial components in high-temperature metallurgical processes, are subjected to extreme conditions, including temperatures surpassing 1500°C and intense impacts from high-velocity gas streams and molten iron. Constructed from high-purity copper, these tuyeres demand exceptional rigidity, strength, and resistance to thermal cracking. Traditional welding techniques often prove inadequate for copper surface treatment due to its high melting point and unique material properties.
FNS Pipeline Technology Co., Ltd. has pioneered an advanced plasma powder overlay solution tailored specifically for copper blast furnace tuyeres. Leveraging our proprietary plasma power supply, we employ a specialized process that compresses arc energy and utilizes precise waveforms and ion treatments. This enables the seamless fusion of copper surfaces with high-performance alloy powders, creating a durable overlay that significantly enhances the tuyeres’ resistance to high temperatures and mechanical stress.
