In today’s increasingly competitive steel industry, the mold copper plate, as the “heart” component of continuous casting production, its performance directly determines the production efficiency and product quality of enterprises. This article will take you through the latest breakthroughs in mold copper plate technology and how to maximize production efficiency by optimizing the performance of copper plates.
Mold copper plate: The core guarantee of steel production
The mold copper plate is an indispensable key component in the continuous casting production line and undertakes three core missions:
High-efficiency heat transfer expert: Ensures rapid and uniform solidification of molten steel, enhancing production efficiency.
Quality Guardian: Ensuring the surface finish and internal density of the cast billet.
Cost control specialist: Reduce the procurement cost of spare parts by extending their service life.
As the steel industry transitions towards high-quality development, the performance requirements for mold copper plates are also increasing day by day. The traditional copper plate technology is no longer able to meet the demands of modern efficient continuous casting, and technological innovation is imperative.
Industry Pain Points: Analysis of Common Failure Issues of Mold Copper Plates
In actual production, mold copper plates mainly face four major challenges:
Coating peeling crisis.
It led to a sudden steel leakage accident.
On average, each accident causes direct losses of over 500,000 yuan.
It accounts for more than 35% of unplanned downtime.
Thermal fatigue crack.
It shortens the lifespan of copper plates by 30-40%.
Increase the surface grinding amount of the cast billet.
It affects the operation rate of the continuous casting machine.
Double blow of wear and corrosion.
The annual replacement cost is as high as several million yuan.
Restrict the implementation of the high drawing speed process.
It affects the lubrication effect of the protective slag.
The problem of heat deformation.
It leads to the defect of billet bulging.
Increase the risk of steel leakage.
It affects the arc alignment accuracy of the mold.
