본 발명은 연주설비의 슬라브 연속 전달 장치에 관한 것으로서, 더욱 상세하게는 미니밀 연주설비에서 슬라브(slab)를 절단 후 이어지는 슬라브를 전단 롤러(Roller)로 연속해서 전달하여 이동되는 슬라브의 하향으로 인해 발생되는 설비고장을 미연에 방지할 수 있도록 마련된 연주설비의 슬라브 연속 전달 장치에 관한 것이다.The present invention relates to a slab continuous transmission device of the performance equipment, and more particularly, the slab (slab) in the mini-mill performance equipment is generated due to the downward movement of the slab that is continuously transferred to the shear roller (Roller) after the subsequent slab (slab) It relates to a slab continuous transmission device of the performance equipment provided to prevent the equipment failure in advance.

일반적으로, 미니밀 연주설비에서는 철이 주성분으로 된 두꺼운 슬라브를 절단장치에 의해서 절단하게 되며, 이 미니밀 연속주조 공정에서 일정길이로 슬라브를 절단한 후, 절단기 후단 테이블 롤로 절단된 슬라브를 연속해서 전달하게 된다.In general, in a mini mill performance equipment, a thick slab mainly composed of iron is cut by a cutting device. In the mini mill continuous casting process, the slab is cut to a certain length, and the slab cut by the table roll after the cutter is continuously transferred. .

도 1에서 보듯이, 연주기에서 배출되는 슬라브(10)를 일정한 크기로 절단하기 위해 절단기(20)가 마련된다. 이 절단기(20)의 전방부분으로는 절단기(20)에서 절단된 슬라브(10)를 이동시키기 위해 전단 롤러(30)가 구비되고, 이 전단 롤러(30)의 회전에 의해 슬라브(10)는 테이블 롤(40)로 운반되어 진다.As shown in Figure 1, the cutter 20 is provided to cut the slab 10 discharged from the player to a certain size. The front part of the cutter 20 is provided with a shear roller 30 to move the slab 10 cut from the cutter 20, the slab 10 is a table by the rotation of the shear roller 30 The roll 40 is carried.

종래의 슬라브 절단 과정을 보면, 기존의 절단기(20)는 이 절단기(20)가 회전하면서 슬라브(10)를 절단하고 일정각도로 머무는 상태에서 이동 롤러(50)와 실린더(60)로 구성된 기존설비가 동작하여 실린더(60)가 후단 방향으로 빠지면서 슬라브(10)를 후단 테이블 롤(40)로 전달하여 주었다.Looking at the conventional slab cutting process, the existing cutter 20 is the existing equipment consisting of the moving roller 50 and the cylinder 60 in the state in which the cutter 20 rotates to cut the slab 10 and stay at a predetermined angle. The cylinder 60 was delivered to the rear end direction while the slab 10 was transferred to the rear end table roll 40.

그러나, 상기와 같은 구성으로 이루어진 종래의 슬라브 절단장치는 다음과 같은 문제점이 있다.However, the conventional slab cutting device made of the above configuration has the following problems.

상기와 같이 슬라브를 후단 롤러 테이블로 전달하여 주면, 이때 고열부에 근 접한 실린더 및 이동롤러등 프레임부가 열화 되어 손상되는 문제가 발생하였다.When the slab is delivered to the rear roller table as described above, a problem arises in that the frame parts such as the cylinder and the moving roller, which are in close proximity to the high heat portion, are deteriorated and damaged.

현재 슬라브는 절단장치에서 일정한 길이로 절단 후 이동하는 상태에서 절단기에 부착된 롤러가 인출되면서 다음 롤러로 슬라브를 전달하여 주게 되나, 이렇게 되면 이동하는 절단기를 중간에 일정시간 정지시켜야 하는 문제점이 있었다.At present, the slab is transferred to the next roller while the roller attached to the cutter is pulled out while cutting and moving to a predetermined length in the cutting device, but this causes a problem of stopping the moving cutter for a predetermined time in the middle.

또한, 상기 절단기의 주변 온도가 500도 이상의 고온이며 절단기 절단시의 충격력과 진동에 의한 설비손상이 일어나는 문제점과, 절단기에 절단되어 이동되는 슬라브의 선단부가 테이블 롤러 하부로 들어가는 하향 처짐이 발생하여 슬라브 이동장치의 조업을 중단하는 문제점이 있었다.In addition, the ambient temperature of the cutter is a high temperature of more than 500 degrees and the damage caused by the impact force and vibration during the cutting of the cutter, and the downward deflection that the front end of the slab cut and moved to the cutter enters the lower table roller occurs There was a problem of stopping operation of the mobile device.

또한, 종래에는 절단기 구조물에 부착된 이동장치로 내부 냉각 타입으로 구성된 슬라브 연속 정잘 장치를 사용하였으나 슬라브 절단시 충격력과 설비진동에 의한 롤러 구동불가 및 후단 테이블 롤러로 연속 전달 시 변형 발생에 의한 고장으로 생산차질의 원인이 되고 있는 실정이다.In addition, in the past, a slab continuous refiner composed of an internal cooling type was used as a moving device attached to a cutter structure, but roller driving was not possible due to impact force and equipment vibration when cutting the slab and failure due to deformation during continuous transfer to the rear table roller. This is the cause of production disruption.

본 발명은 상기와 같은 문제점을 해결하기 위해 제안된 것으로서, 슬라브를 절단시 전달장치의 변형과 손상에 의한 설지 고장을 방지하는데 목적이 있으며, 또한 고열에 의한 설비 열화를 방지하여 설비 수명을 연장할 수 있는 연주설비의 슬라브 연속 전달 장치를 마련하는데 그 목적이 있다.The present invention has been proposed to solve the above problems, and the object is to prevent installation failure due to deformation and damage of the transfer device when cutting the slab, and also to prevent the deterioration of the equipment due to high temperature to extend the life of the equipment. The purpose is to provide a continuous slab transmission device of the performance equipment.
