  • Method for thermal treatment of wire lashings and a continuous-heating furnace for performance of the method
    Patent number: 4408986
    Abstract: A method for thermal treatment of horizontal wire rings with convective heat transfer by means of circulated furnace gases, characterized in that said wire rings, particularly for thermal treatment above temperatures of 650.degree. C. are acted upon in the resting state from two sides, from the top and the bottom, with a directed flow of furnace gases in order to generate a turbulent flow condition in the center of said ring. As a result of this method, it is proper to connect wire rings for uniform thermal treatment. An apparatus for carrying out the treatment is also disclosed.
