Abstract

주조말기 슬래브 여재 발생감소 및 자동스톱 기능 연계에 따른 일인제어 기반조성 및 주조말기 조업안정화를 도모할 수 있는 턴디쉬 슬라이딩 노즐 최적제어방법은 DCS(17)를 통하여 수집된 래들 및 턴디쉬 중량센서(15,16)의 데이터와 PLC(19)의 주조데이터를 입력하여 절단기(24a, 24b)를 제어하고 PLC(19)에 제어명령을 출력하는 P/C(18)와, 몰드폭 데이터 및 주조길이 데이터와 핀치를 드라이버(21)의 피드백 제어 데이터에 따라 턴디쉬 슬라이딩노즐(14a,14b) 핀치를 드라이버(21), 제어표시판넬(20)을 제어하는 PLC(19)를 포함하는 연속주조설비에서, 주조말 차지래들 주입개시시점에서 터렛주조 위치의 래들중량 및 턴디쉬 중량을 계산하고, 래들중량, 턴디쉬중량, 주조속도, 몰드 상단폭을 이용하여 자동스톱 수행 및 노멀 주조중 스트랜드별 예상주조길이를 계산하고, 턴디쉬 슬라이딩 노즐 클로즈 발생가정하에서 스트랜드별 허용공차 및 슬래브 할당에 따른 주조길이를 조정하고, 스트랜드별 최적주조길이에 의거하여 주조속도를 계산하여 제어표시 판넬에 가이던스 하면서, 자동주조스톱시점 판단 및 제어명령을 발생시킨다.Optimal control method for tundish sliding nozzles that can reduce the occurrence of end-slab slag mediation and linkage with automatic stop function and stabilize the end-casting operation is the ladle and tundish weight sensor collected through DCS (17). P / C 18 which inputs data of 15 and 16 and casting data of PLC 19 to control cutters 24a and 24b and outputs a control command to PLC 19, mold width data and casting length According to the feedback control data of the driver 21 and the pinch data, the twisted sliding nozzles 14a and 14b may be used in a continuous casting facility including a driver 21 and a PLC 19 for controlling the control display panel 20. Calculate the ladle weight and tundish weight at the turret casting position at the start of the injection end charge ladle injection, perform automatic stop using ladle weight, tundish weight, casting speed, mold top width, and predict the strands during normal casting Calculate the casting length Under the assumption that tundish sliding nozzle close occurs, it adjusts casting length according to tolerance and slab allocation per strand, calculates casting speed based on optimum casting length per strand, guides the control display panel, and determines automatic casting stop time. Issue a control command.
