Guidelines for Welding Cast Iron - Lincoln ElectricRemembering this is helpful when welding cast iron: during and after welding, the casting must either be allowed to cool slowly, or should be kept cool enough that the rate of cooling is not important. A critical temperature in most cast iron is about 1450 degrees F. When at this temperature, conditions that can lead to cracking occur.

Thermal Analysis and Process Control for Compacted ...The mantra of process control is: you can't control what you can't measure. Accordingly, process control must begin with an accurate measurement of the iron. In order for a liquid to transform to a solid, it must release heat. The basis of thermal analysis is that this liberation of heat, illustrated in cooling curve shown in Figure 2, can

Iron ore pelletizing Grate-KilnTM systemdrying, induration and cooling zones. Any change in one section effects the residence time in another. In the Grate-Kiln system, independent speed control of the grate, kiln and cooler are available to the operator. This provides process flexibility to adjust to changes in concentrate feed. Pelletization process
Learn About Quenching in Metalworking - The BalanceQuenching is a rapid way of bringing a metal back to room temperature after heat treatment to prevent the cooling process from dramatically changing the metal's microstructure. Metalworkers do this by placing the hot metal into a liquid or sometimes forced air.
