ABSTRACT:
A method for the heat treatment of extended steel products such as, for example, rods, pipes, work pieces, etc., while the products are in motion. The products (13, 14, 33, 34, 35) are caused to be heated by DFI burners (6-11, 16-20) (where “DFI” is an abbreviation for “direct flame impingement”), which burners are caused to be located such that one set of burners (6, 7, 8, 9, 10, 11), (16, 17, 18, 19, 20) essentially covers the circumference of the products, and in the burners are caused to be located integrated into arrangements (2-4, 13) that transport the product in a direction that is perpendicular to a plane in which the flames of the burners essentially lie.
