摘要:PURPOSE:To make the length of a billet from a cutting command up to cutting constant by performing a cutting command after calculating an adjusting time bad on the minimum time necessary for the maximum feeding speed of a continuously casting billet and an arithmetic control, and the operation delay time from the cutting command up to cutting. CONSTITUTION:The height of the molten metal level inside a mold 3 is made constant by controlling the rotary speed of a pinch roll 5 by a molten level control panel 6. The pul counter 12 of a measuring roll 10 is inputted to a cut length control panel 13, a cutting command is outputted to a cutting machine 18 in the specified length L and a fed out billet 17 is cut. In that ca the delay t2 on the mechanism operation from a cutting command up to cutting is constant, but the length S of after the command till cutting varies with the fluctuation in the feeding speed of the billet 17. Now, the feeding speed V and maximum feeding speed Vmax detected by an A/D converter 19, the minimum time t1 min necessary for an arithmetic control and the delay time t2 from a cutting command till cutting are inputted to an arithmetic control device 13 and after operating an adjusting time t1 the cutting command is nt. With this method the length S until the actual cut after cutting command is made constant and the length of the billet 17 cut in succession becomes constant.
