Document Type and Number:
Japanese Patent JP4077778
Kind Code:
B2
Abstract:

To provide a method for treating a heat insulating chlorofluorocarbon-containing cold iron source by which heat insulating chlorofluorocarbon is decomposed stably and the cost effectiveness of which is improved.

This method for treating the heat insulating chlorofuorocarbon-containing cold iron source being a scrapped automatic vending machine and/or a scrapped refrigerator, in each of which a chlorofluorocarbon-containing heat insulating material is contained, by throwing the cold iron source in a cold iron source melting furnace or a converter comprises the steps of: removing the chlorofluorocarbon being a cooling medium from the scrapped automatic vending machine and/or the scrapped refrigerator; covering the outside of the cooling medium-removed heat insulating chlorofluorocarbon-containing cold iron source with a steel plate; and throwing the steel plate-covered heat insulating chlorofluorocarbon-containing cold iron source into the cold iron source melting furnace or the converter.
