Abstract

PURPOSE: To make the temperature of a slab uniform by detecting the temp. of the slab and adjusting the electric power of the induction heating coil provided between roughing mills and finishing mills.
CONSTITUTION: An induction heating coil 5 of width (l) equal to the temp. graded part of skid marks is provided to a conveying line, and electric power is supplied to the coil 6 when one point of the skid mark 2 of a slab 1 comes to the outlet side 6 of the coil 5. In proportion to the time up to the point (4), the quantity of the thrown electric power increases and after the point (4), it assumes a fixed quantity of electric power. Next, the supply of the electric power is stopped when the end point (7) of the flat part of temp. comes to the outlet side 6 of the coil 5. The thrown electric power is controlled in proportion to the product of slab conveying speeds and the temp. drop of the skid marks. Namely, a thermometer 7 is provided at (d) cm before the induction heating coil 5 and after this thermometer 7 detects the temp. at the end of the skid mark 2, the electric power is thrown on in (d+l)/ V sec. after this and is turned off in (d+m)/V sec. after.
