Abstract
PURPOSE:To increase the rolling pressure in the central part of rolling blank and produce the thick steel plate of high quality free from loose structure, etc. by providing serrations to roughing rolls and rolling the blank with these rolls then rolling the same flat. CONSTITUTION:Steel ingot 4 is rolled with serrated rolls 5 which comprise providing serrations of convex or concave form of more than 10mm in diameteral difference to roughing rolls, by which a blank 6 of convex or concave form in section is made. Next, this is rolled with flat rolls 7 to a flat blank or thick steel plate 8. This method increases the rolling pressure in the central part of the blank of the specific range, and causes the casting structure in the central part of the steel ingot of the specific range to be well forged.
