What is the difference between oil cooling and water cooling?
1 Answers
Here are the specific differences between oil cooling and water cooling: 1. Cooling time: Since oil cools slower than water, oil cooling takes longer than water cooling. 2. Quenching hardness: Water cooling achieves higher hardness, while oil cooling results in lower hardness. 3. Quenching deformation: Water cooling causes greater deformation, while oil cooling causes less. 4. Quenching cracking tendency: Water cooling has a higher tendency to cause cracking, while oil cooling has a lower tendency. 5. Depth of hardened layer: Water cooling produces a deeper hardened layer, while oil cooling produces a shallower one. 6. Environmental pollution: Water is basically non-polluting, whereas waste oil is polluting, oil fumes are also polluting, and there is a potential safety hazard of combustion.
