Device for cooling the crystallizer in a plant for casting metal ingots with a periodic discharge thereof

摘要

A device for cooling the crystallizer in a plant for casting metal ingots comprises pipelines connecting at least two coolant vessels to the pump and the crystallizer. According to the invention, one of the vessels incorporates an arrangement for lowering the coolant temperature, while the other one incorporates a heater for raising the coolant temperature to 400 DEG C. Both vessels are connected to pipelines bringing the coolant to the crystallizer and taking it away there from, whereas the pipelines and pipe connections mount valves to ensure an alternate delivery of coolants from said vessels to the crystallizer.
