ABSTRACT:
The invention is directed to an arrangement of high thrust burners with control systems for a heating furnace which heat metal or similar product, in order to erase developing cold skid marks. The location of these burners is specified, transversely and longitudinally as well as their position with the product face. This invention considers the flow of gases inside of the furnace and the necessary burner characteristic required for the application of these burners to the developing skid marks and the reasons for the specifications. The burners are required to be such that the maximum available heat in the flame is applied at the spot required in order to heat those spots at a faster rate than the cooling effect of the water cooled parts, which are the initial causes of the cold spots. Moreover, it is specified as to the control systems and to the part in which they play in the operation of the skid mark erasure burners.
