  • Patent number: 4292016
    Abstract: Process and apparatus for solidifying molten materials by pouring onto a substrate and cooling, in which undesired crystallinity is avoided by first forming a solidified protective stabilizing skin on the melt surface, e.g. by carefully controlled air cooling or dusting with powdered material, before more vigorous cooling by fluid coolant, e.g. air or water, directed against the solidified skin. Optionally, silicone liquids and/or kerosene or other hydrocarbons of lower boiling range are used in minor amounts to treat the melt before pouring to promote the formation of amorphous solidified material and provide increased hardness on aging. When using an endless belt as substrate, the plain solidification surface may be modified by superposing a skeleton framework to form selectively shaped tablet or bar molds. The process and apparatus are particularly applicable to the solidification of molten sulphur.
