Abstract
Abstract 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*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. Successive change of coolant temperature in the crystallizer brings more favourable conditions for forming an ingot and its discharge and for producing an ingot with an upgraded surface quality.

Claim 1
Independent Claim
182 words
A device for cooling the crystallizer in a plant for casting metal ingots with a periodic discharge thereof, comprising: a coolant storage; a vessel for low-temperature coolant connected by pipeline to said storage; an arrangement for reducing the coolant temperature built in into said vessel for low-temperature coolant; an inflow pipeline connecting said crystallizer being cooled to said vessel for low-temperature coolant; an outflow pipeline connecting said crystallizer being cooled to said vessel for low-temperature coolant; a vessel for high-temperature coolant coupled by means of pipe connections to said inflow and outflow pipelines; a heater mounted in said vessel for hightemperature coolant to heat it to approximately 400*C; valves installed on said pipelines and pipe connections for an alternate connection of each of said vessels to said crystallizer being cooled for the purpose of an alternate inflow to or outflow from the crystallizer of the coolant of the corresponding temperature and for a correspondingly alternate disconnection of said vessels from the crystallizer; a pump connected to said inflow pipeline to alternately deliver the coolant from said vessels to said crystallizer being cooled.

A device for cooling the crystallizer in a plant for casting metal ingots with a periodic discharge thereof, comprising: a coolant storage; a vessel for low-temperature coolant connected by pipeline to said storage; an arrangement for reducing the coolant temperature built in into said vessel for low-temperature coolant; an inflow pipeline connecting said crystallizer being cooled to said vessel for low-temperature coolant; an outflow pipeline connecting said crystallizer being cooled to said vessel for low-temperature coolant; a vessel for high-temperature coolant coupled by means of pipe connections to said inflow and outflow pipelines; a heater mounted in said vessel for hightemperature coolant to heat it to approximately 400*C; valves installed on said pipelines and pipe connections for an alternate connection of each of said vessels to said crystallizer being cooled for the purpose of an alternate inflow to or outflow from the crystallizer of the coolant of the corresponding temperature and for a correspondingly alternate disconnection of said vessels from the crystallizer; a pump connected to said inflow pipeline to alternately deliver the coolant from said vessels to said crystallizer being cooled.
Claim 3
Dependent Claim
58 words
A device according to claim 1, wherein an auxiliary pump is provided, connected by means of pipe connections to each of said vessels and to said pipeline coupled to said coolant storage, and the walls of said vessels above the required level of coolant contained therein, have holes forming a passage to communicate these vessels with each other.
Claim 4
Dependent Claim
30 words
A device according to claim 1, wherein a reservoir is provided, connected by means of pipe connections to a source of compressed gas and to one of said coolant-containing vessels.
