COOLING CONTROL DEVICE AND METHOD FOR A THIN SLAB MOLD, WHICH AUTOMATICALLY CONTROLS THE AMOUNT OF COOLING WATER SUPPLIED TO EACH COPPER PLATE ACCORDING TO THE INNER STATE OF A MOLD

摘要

PURPOSE: A cooling control device and method for a thin slab mold are provided to obtain thin slab with high surface quality by automatically controlling the amount of cooling water supplied to each copper plate according to the inner state of the mold in a continuous casting process.;CONSTITUTION: A cooling control device for a thin slab mold comprises a memory(110) and a control unit(160). The memory stores one or more operation parameters among the initial cooling water according to the thickness of a copper plate of a mold(30), the current casting speed, the thickness of the mold, the current cooling water amount, and the intake/drain temperature change of cooling water. The control unit calculates target heat flux according to the casting speed stored in the memory, calculates the current heat flux of each copper plate using the amount of cooling water currently supplied to each copper plate and the intake/drain temperature change of cooling water, and individually controls the amount of cooling water supplied to each copper plate using the difference between the current heat flux and the target heat flux.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Memory; (140) Input unit; (150) Display unit; (160) Control unit; (170) Cooling water amount adjusting unit; (AA,BB) Cooling water; (CC) Casting speed(From pinch roll)
