Graphite mold for steel casting

Iron and steel casting graphite molds are mainly based on the good performance of graphite. Generally speaking, graphite's high temperature resistance, corrosion resistance, chemical stability, thermal shock resistance and other functions are the prerequisites for graphite to enter the mold industry. At the same time, graphite is also used in graphite molds for continuous casting and semi-continuous casting of non-ferrous metals.

In recent years, domestic and foreign countries are promoting advanced production methods such as direct continuous (or semi-continuous) manufacturing of rods or pipes from the molten metal state. China has begun to adopt this method in copper, copper alloy, aluminum, aluminum alloy and other aspects. Artificial graphite is considered a suitable material as a mold for continuous casting or semi-continuous casting of non-ferrous metals. Production practice proves that due to the use of graphite molds, due to its good thermal conductivity (the thermal conductivity determines the solidification speed of the metal or alloy), the mold's self-lubricating performance is good, and other factors not only increase the mold speed, but also Accurate, smooth surface, uniform crystal structure, can be directly processed in the next process. This not only greatly improves the yield rate and reduces the loss of waste products, but also significantly improves the product quality.

Continuous casting methods include vertical continuous casting and horizontal continuous casting.
