  • Method of marking hot material and apparatus therefor
    Patent number: 4253393
    Abstract: A combustible stencil held by holders is disposed at a position some distance apart from the end face of a hot material; immediately thereafter, a coating composition is sprayed onto the hot material through perforations in the stencil from behind to carry out the marking; the stencil is used only once and burned by the potential heat of the hot material upon marking; and a new stencil is used each time for marking. The combustion starting time is controlled by previously moistening the stencil as necessary.
