Abstract
Methods for treating a steel billets with carbon black in order to increase quality. This increase in emissivity will enhance the radiative heat transfer to the billet, and also improve the temperature homogeneity of the billet, thus improving the production rate and quality. The carbon black layer on the surface will act as a barrier to prevent or slow the rate of scale formation.
Claims22
A method of treating a steel billet comprising;
- a) providing a source of highly-carbon-laden gas;
- b) providing a steel workpiece;
- c) directing said highly-carbon-laden gas to at least one surface of said steel workpiece, thereby producing a coated steel workpiece;
- and
- d) introducing said coated steel workpiece to a steelmaking process.

A method of treating a steel billet comprising;
- a) providing a source of a highly-carbon-laden gas;
- b) providing a steel workpiece;
- c) introducing said steel workpiece to a first steelmaking process;
- d) directing said highly-carbon-laden gas to at least one surface of said steel workpiece, thereby producing a coated steel workpiece;
- and
- e) introducing said steel workpiece to a second steelmaking process.
