Скачать или смотреть How are LDK bearings produced (02)-- heat treatment

This is the fully automatic mesh belt heat treatment line of LDK bearings, crucial for enhancing bearing inherent quality.
Heat treatment transforms material structure, enhancing mechanical properties, wear resistance, toughness, and extending bearing lifespan for improved performance and longevity.
All the heat treatment process are controlled by the computer, including temperature setting, crawler rotate speed and so on, all data can be traceable.
Before heat treatment, inner rings of bearing should be drilled with setscrew hole, guaranteeing the precise angle of the two holes.
After heat treatment, our operator inspecting hardness by gauge for each lot, setscrew holes annealing and crack inspection
