During continuous casting, a dummy bar is initially inserted into the mold to establish the initial solidification front. The molten metal is then poured around the dummy bar, which provides support and helps control the shape and dimensions of the cast product. Once the casting is complete and the solidified metal strand has been withdrawn from the mold, the dummy bar needs to be removed and replaced with a new one for the next casting cycle.
A dummy bar car is used to transport the dummy bar into and out of the continuous casting machine. It typically consists of a sturdy frame, wheels or tracks for movement, and a mechanism for securely holding and releasing the dummy bar. The car is designed to safely and efficiently transfer the dummy bar between the mold area and the dummy bar storage area.
The dummy bar car is operated by a crane or other lifting equipment, which lifts and positions the dummy bar car in the appropriate location. The car is then moved into position, and the dummy bar is inserted or removed from the mold using the car's holding and releasing mechanism.
The use of a dummy bar car helps streamline the continuous casting process by facilitating the insertion and removal of the dummy bar. It ensures the efficient and safe transfer of the dummy bar, minimizing downtime and maximizing productivity.
Overall, a dummy bar car is an essential component in the continuous casting process, enabling the smooth operation of inserting and removing the dummy bar, which is crucial for maintaining the integrity and quality of the cast products.
