Abstract

An installation structure for a heater tube of a deposit furnace is provided to prevent slag from growing due to reduction of air contact for a molten metal by disassembling the heater tube with an upper plate supporter of a heating path. An installation structure for a heater tube of a deposit furnace comprises a heater(22) installed at the center, a lumi board installed at the outside of the heater to fix the heater, and a heater tube(20) having a tub at the outside of the lumi board to be modulated. The modulated heater tube is combined to a main body of a heating path(10) having a lumi board plate(30) to separate the heater tube with an upper plate supporter(11) to the heating path when the heater tube is disassembled. Consequently, the safety of working is increased by dismantling the heater tube with the upper plate supporter of the heating path.

본 발명은 침적식 보온로의 히터튜브 설치구조에 관한 것이다.The present invention relates to a heater tube installation structure of the immersion thermal insulation furnace.

본 발명은 보온로에 설치되는 히터튜브 분해시 보온로의 상판과 같이 분해되도록 구성함으로써 용탕의 공기접촉 최소화로 인한 슬래그의 성장을 억재함과 아울 러 모듈화된 히터튜브구조에 의해 가동율 향상 및 작업안전성을 도모할 수 있도록 한 것이다.The present invention is configured to be disassembled like the top plate of the heating furnace when disassembling the heater tube installed in the heating furnace to inhibit the growth of slag due to minimizing the air contact of the molten metal, as well as to improve the operation rate and work safety by the modular heater tube structure It was intended to be.

일반적으로 보온로는 주조기에 공급되는 용탕의 보관을 하기 위해 제공되는 설비로 내부구조로는 2개소(보온실,출탕구)로 구분되어 있으며, 저탕구에 3개의 히터가 AL용탕에 침적되어 적정온도(약 700℃)를 유지하게 된다.In general, the thermal insulation furnace is provided to keep the molten metal supplied to the casting machine. The internal structure is divided into two places (heat insulation chamber and hot water spout), and three heaters in the hot water spout are deposited on the AL molten metal. Maintaining the temperature (about 700 ° C).

이와 더불어 하부 용탕 통로를 통해 저탕구와 출탕구는 동일온도를 유지하는 장비이며, 주조기는 로더를 이용하여 출탕구에서 용탕을 받도록 하는 구조로 제공되고 있다.In addition, the bottom of the molten metal and the tapping through the melt passage is the equipment to maintain the same temperature, the casting machine is provided in a structure to receive the molten metal at the tap using the loader.

또한 상기 보온로(1)에 설치되는 히터튜브(2)는 도 3 및 도 4에 도시된 바와 같이 중앙에 히터(4)가 설치되고 상기 히터(4)의 외측에 히터(4) 고정을 위한 루미보드(5)가 설치됨과 동시에 상기 루미보드(5)에 튜브(3)가 설치된 상태 그대로 보온로(1)에 결합되어 있기 때문에 슬래그 성장시 상기 히터튜브(2)와 보온로(1) 본체 사이에 볼트체결에 의한 간섭발생부위(A)가 발생될 뿐만 아니라 수작업 튜브(3) 파괴로 분해후 신품으로 교환하게 되는 문제점 및 튜브(3) 및 히터(4) 교환시 리프터(6) 장치를 불가피하게 사용하게 되는 문제점이 있다.In addition, the heater tube (2) installed in the thermal furnace (1) has a heater (4) is installed in the center as shown in Figure 3 and 4 and for fixing the heater (4) on the outside of the heater (4) Since the lumi board 5 is installed and the tube 3 is installed on the lumi board 5 as it is coupled to the heating furnace 1 as it is, the heater tube 2 and the heating furnace body 1 during slag growth. Not only does the interference (A) occur due to bolting between them, but also the problem of replacing the new tube after disassembly by breaking the manual tube (3) and replacing the tube (3) and heater (4). There is a problem inevitably used.

또한 상기 보온로(1)에서 히터튜브(2) 교환시 튜브(3) 외곽에 성장된 슬래그가 보온로(1) 상판 고정지그와의 간섭이 항시 발생됨에 따라 수작업으로 튜브(3)를 파손시켜 용탕제거와 함께 튜브(3)를 파괴하고 있어 작업자의 안정사고 위험성이 매우 클 뿐만 아니라 작업시간이 과다하게 발생하게 되며 용탕품질 저하는 물론 리프터(6) 설치에 따르는 설비비가 증가하게 되는 문제점이 있다.In addition, as the slag grown outside the tube 3 when the heater tube 2 is replaced in the heating furnace 1, interference with the fixing jig of the upper plate of the heating furnace 1 is always generated, thereby manually damaging the tube 3. With the removal of the molten metal and the tube 3 is destroyed, the risk of safety accidents of the operator is not only very high, but also excessive work time occurs, and the quality of the molten metal is increased, and the equipment cost due to the lifter 6 is increased. .

본 발명은 보온로에 설치되는 히터튜브 분해시 보온로의 상판과 같이 분해되도록 구성함으로써 용탕의 공기접촉 최소화로 인한 슬래그의 성장을 억재함과 아울러 모듈화된 히터튜브구조에 의해 가동율 향상 및 작업안전성을 도모할 수 있도록 함을 목적으로 한다.The present invention is configured to be disassembled like the upper plate of the heating furnace when disassembling the heater tube installed in the heating furnace, thereby inhibiting the growth of slag due to minimizing the air contact of the molten metal and improving the operation rate and work safety by the modular heater tube structure. It aims to be able to plan.

이를 위해 본 발명은 중앙에 히터(22)가 설치되고 상기 히터(22)의 외측에 히터(22) 고정을 위한 루미보드(5)가 설치됨과 동시에 상기 루미보드(5)의 외측에 튜브(3)가 설치되는 히터튜브(20)를 모듈화하되, 상기 모듈화된 히터튜브(20)를 루미보드플레이트(30)가 설치된 보온로(10) 본체에 결합하여 히터튜브(20) 분해시 상기 히터튜브(20)가 보온로(10) 상판 거치대(11)와 같이 분해될 수 있도록 하는 것을 특징으로 하는 침적식 보온로의 히터튜브 설치구조를 제공함으로써 상기 목적을 달성하고자 한다.To this end, in the present invention, the heater 22 is installed at the center and the lumi board 5 for fixing the heater 22 is installed at the outside of the heater 22 and at the same time the tube 3 is disposed outside the lumi board 5. The modularized heater tube 20 is installed, but the modularized heater tube 20 is coupled to the body of the heating furnace 10 in which the lumi board plate 30 is installed to disassemble the heater tube 20 when the heater tube ( It is intended to achieve the above object by providing a heater tube installation structure of the immersion thermal insulation furnace, characterized in that 20) can be disassembled, such as the upper plate holder (11) of the thermal insulation furnace (10).
