HEAT EXCHANGE METHOD, HEAT EXCHANGE MEDIUM, HEAT EXCHANGE DEVICE, PATENTING METHOD, AND CARBON STEEL WIRE
Document Type and Number:
WIPO Patent Application WO/2020/158704
Kind Code:
A1
Abstract:
The present invention provides a novel heat exchange medium as an alternative to lead. A carbon steel wire (1A) that is heated in a heating furnace (11) is allowed to pass through a bath (12A) in which a liquid-phase Mg-Al-Ca alloy (20) prepared by melting an Mg-Al-Ca alloy containing Mg (magnesium), Al (aluminum) and Ca (calcium) as the main component elements is stored. Upon the passing through the bath (12A), the carbon steel wire (1A) that has been heated to, for example, about 950°C in the heating furnace (11) is cooled to about 550°C. The Mg-Al-Ca alloy has neither toxicity nor environmental load.
