The Continuous Heat Treatment Process at Emerson Forge Pvt. Ltd.
Attaining desirable mechanical properties is the key step of forging manufacturing. Mechanical properties are the ones that decide the quality and durability of the forgings. To come up with highly durable and desirable forgings, the engineers at Emerson go for specific heat treatment processes. They work at the microstructure levels to get the best outcomes. We follow the three-step heat treatment process (as per the standard procedure), which is as follows:
1. Heating beyond the critical temperature
Our experts calculate the metal or alloy’s critical temperature value and heat the metal beyond that temperature to attain changes in its microstructure and further its metallic characteristics.
2. Holding the metal at the heating temperature
Holding the metal at a specific temperature (heating temperature) ensures that the entire metal has a uniform microstructure. Heating furnaces are specifically designed to maintain this temperature.
The metal is further subjected to lower temperatures for Microstructure Transformation. The final outcome is metal with desirable mechanical properties. At Emerson, we generally use a furnace with a well-regulated temperature to cool the metal. Sometimes, air cooling is also preferred by our engineers.
It often happens that a single heat treatment cycle cannot alter the microstructure of the entire metal. Hence, our engineers alter the duration of all the three steps to get the best results.
