Abstract
PURPOSE: To obtain a conditioning method which is superior in yield and performance and by which the quality of products can be enhanced by controlling the moving speeds of metallic ingots passing through a scarfer according to the surface characteristics of metallic ingots such as steel slabs.
CONSTITUTION: While a slab 81 is passing the position of HMD21 after the completion of required initial operation, the count results of an up counter 24 are attained to the pulse number P corresponding to the slab length by the input from a pulse transmitter 23. When the slab comes to the position of a hot scarfer 94 by the revolutions of roller tables 11, 12, etc., the operator starts this to start scarfing, knows the state of flaws through information, visual observation, etc., and controls the slab moving speed during passing through the scarfing to make it faster or slower with a variable resistance 10. At the starting of the scarfing, said P is transferred and set to a down counter 26, and the length of the unsarfed part of the slab is expressed by the input from a pulse transmitter 27. After the progression of the scarfing, control devices 11bW14b receive stop signals, by which motors 11aW14a are stopped. The operator stops scarfing after the stoppage of the slab.
