Steelmaking-Casting of Molten Steel by Decarburization
Steelmaking–continuous casting is a complex process. The method of selecting a ladle which also functions as a storage device follows a specific process of the production plan. In ladle matching several ladle attributes are considered. However matching objectives are difficult to achieve simultaneously. Different molten steel properties have contributed to the complexity of matching

Next the casting cracks were prepped for what we call lock weld (Lock weld tries to reestablish the holding structure of the casting) Once that was completed the crack area was prepped grounded then brazed welded. After the braze welding the weld was prepped the casting was then remagnafluxed. A 3rd procedure was done called pinning.
