본 고안은 금속열처리 시편의 재사용이 가능한 내부온도 측정장치에 관한 것으로, 좀더 상세하게는 스테인레스나 고강도 강판등 난가공재의 정확한 승온속도 및 냉각속도 측정실험을 위한 내부온도 측정실험이 필수적인 바 재사용이 가능하여 소재절감이 되는 시편 내부온도 측정장치에 관한 것이다.The present invention relates to an internal temperature measuring device capable of reusing metal heat treated specimens. More specifically, internal temperature measuring experiments are essential for accurate heating rate and cooling rate measurement experiments of hard materials such as stainless steel or high strength steel sheets. The present invention relates to a specimen internal temperature measurement device that can reduce material.
통상적으로, 일반 금속의 열처리 작업시 시편의 표면에 열전대 연결시편의 표면온도를 측정하였으나, 시편 내부온도 측정시 금속에 구멍을 뚫는 작업 및 고강도 강판등의 구멍뚫기 작업등이 난해했으며 시편의 승온속도 실험 및 냉각속도 측정에서의 가열된 시편이 로(Furnace) 밖으로 나왔을때 대기와의 접촉면인 표면온도만이 급속히 떨어져 시편내부온도는 측정할 수 없었다.Typically, the surface temperature of the thermocouple connection specimen was measured on the surface of the specimen during the heat treatment of ordinary metal.However, when measuring the internal temperature of the specimen, it was difficult to drill holes in the metal and drill holes such as high strength steel sheets. In the cooling rate measurement, when the heated specimen came out of the furnace, only the surface temperature, which is a contact surface with the atmosphere, dropped rapidly, so that the specimen internal temperature could not be measured.
또한, 종래의 선행기술에서는 금속의 열처리 작업시 시편의 표면에 열전대를 연결 표면온도 측정에 국한했으며 시편 내부의 정확한 승온온도 및 승온속도, 냉각속도 측정을 위한 내부온도 측정이 필수적인 관계로 내부온도 측정시 열처리하고자 하는 시편의 표면에서 시편 중심부분까지 드릴로 구멍을 내어 구멍에 열전대를 연결 내부온도를 측정하였으나 이와 같이 할 경우 구멍을 뚫고 그 곳에 열전대를 연결하는등의 불공정 작업이 많았고 시편에 구멍을 냄으로하여 한개의 시편작업만이 가능했으며 스테인레스등 고강도 고인성의 강종등 드릴작업이 힘든 강종등은 열전대를 연결하기 위한 구멍뚫기 작업이 난해했으며 구멍을 뚫는 공정에서 시편에 드릴날이 부러질 경우 재 구멍뚫기 작업을 하는등 문제점이 많았다.In addition, the conventional prior art is limited to the measurement of the surface temperature of the thermocouple connected to the surface of the specimen during the heat treatment operation of the metal, and the internal temperature measurement because the internal temperature measurement for the accurate temperature measurement, temperature rise rate, cooling rate measurement inside the specimen is essential Drilling a hole from the surface of the specimen to be heat-treated to the center of the specimen and connecting the thermocouple to the hole. The internal temperature was measured.In this case, there were many unfair operations such as drilling a hole and connecting a thermocouple there. Only one specimen work was possible, and steel grades, such as stainless steel, high strength and high toughness steel, which were difficult to drill, were difficult to drill to connect thermocouples, and if the drill blade broke on the specimen during the drilling process, There were many problems, such as drilling holes.
본 고안은 상기한 종래의 제반문제점들을 해결하기 위하여 안출한 것으로, 본 고안의 목적은 스테인레스나 고강도 강판등 금속 열처리시 난가공재의 정확한 승온속도 및 냉각속도 측정실험을 위해 필수적인 내부온도 측정실험을 하여 시편의 재사용이 가능하도록 함으로써 소재절감이 되는 금속열처리 시편의 재사용이 가능한 내부온도 측정장치를 제공함에 있다.The present invention was devised to solve the above-mentioned problems. The purpose of the present invention is to perform an internal temperature measurement experiment which is essential for an accurate heating rate and cooling rate measurement experiment of a hardened material during metal heat treatment such as stainless steel or high strength steel sheet. The present invention provides an internal temperature measuring device capable of reusing metal heat treatment specimens, which reduces material by allowing reuse of specimens.

이하 첨부된 도면에 의하여 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 측정장치가 조립된 전체 사시도이고, 제2도는 본 고안의 내부홀더 사시도, 제3도는 본 고안의 시편 및 절연관 사시도 및 제4도는 본 고안의 외부홀더 사시도이다.1 is an overall perspective view of the measuring device of the present invention is assembled, Figure 2 is a perspective view of the inner holder of the present invention, Figure 3 is a perspective view of the specimen and insulator tube of the present invention and Figure 4 is a perspective view of the outer holder of the present invention.
본 고안의 장치로서는 크게 사각형의 시편(1), 절연관(2), 내부홀더(4) 및 바깥면의 둥근홀더(5)로 구분되며 강종에 따라 열전달이 동일하게 하기 위한 같은 재질의 금속을 사용 가공하였으며, 상기 중간부 내부홀더(4)는 가로 70mm, 세로 70mm, 두께 5mm로 제2도에서와 같은 레이져(Laser) 가공하여 중간부에 내부온도 측정용 시편(1)을 끼울 수 있도록 사각구멍(8)을 형성하였다. 제3도는 상기 시편(1)에 열전대(3)가 연결되어 있는 도면이며, 열처리하고자 하는 시편을 상기 열전대(3)를 사용하여 스포트 용접으로 부착하였으며, 상기 시편내부 홀더(4)에 상기 열전대(3)의 접촉을 막기 위해 절연관(2)을 사용하여 상기 내부홀더(4)에 끼울 수 있도록 하였다. 제4도와 같이 상기 시편(1)을 가공 중간내부홀더(4)를 감쌌으며 바깥부분의 테(6)는 최종적으로 스테인레스 와이어로 조임할 수 있도록 양면에 홈을 낸 접합이음테(6)로서 스테인레스 와이어로 조임이 미끄럼을 방지하며 조임이 쉽도록 가공하였다.The device of the present invention is largely divided into a square specimen (1), an insulated tube (2), the inner holder (4) and the round holder (5) of the outer surface, and the metal of the same material for the same heat transfer depending on the steel type The inner holder (4) has a horizontal 70mm, a vertical 70mm, and a thickness of 5mm, so that the middle portion of the inner holder (4) has a square so as to fit the internal temperature measurement specimen (1) in the middle. The hole 8 was formed. 3 is a diagram in which a thermocouple 3 is connected to the specimen 1, and the specimen to be heat-treated is attached by spot welding using the thermocouple 3, and the thermocouple (3) is attached to the specimen inner holder (4). In order to prevent the contact of 3), an insulating tube (2) was used to be fitted to the inner holder (4). As shown in FIG. 4, the specimen 1 was wrapped around the intermediate inner holder 4, and the outer edge 6 was stainless as a jointed edge 6 grooved on both sides to be finally tightened with a stainless wire. Fastening with wire prevents slippage and is processed for easy tightening.
상기 제1도는 홀더에 열전대(3) 연결후 최종적으로 열처리 시편(1)이 끼워져 있는 도면이며 상기 시편(1) 내부는 고온에서 공기와의 접촉을 막기 위해 홀더입구에 석면솜(7)으로 매꿔진 것이다. 본 시편홀더를 중간부, 표면부 각 3개를 판형으로 가공 열처리 작업을 행하였으나 물에 담금질할때 홀더가 휘어져 연속사용이 불가함을 착안으로 상기 제4도에서와 같이 내부를 감싸고 있는 둥근 홀더(5)는 둥글게 가공함으로서 상기 시편(1)을 물에 담금질시 시편(1)이 표면으로부터 금속냉각되어, 상기 시편(1) 내부의 열팽창으로 인하여 고온부로 휠려고 하는 성질을 이용 상기 중간내부홀더(4)를 기준으로 양면에 제1도와 같이 접합 담금질시 홀더의 휨을 방지함으로 재사용이 가능하도록 했다.1 is a view in which the heat treatment specimen 1 is finally inserted after the thermocouple 3 is connected to the holder, and the inside of the specimen 1 is filled with asbestos cotton 7 at the inlet of the holder to prevent contact with air at a high temperature. It is made. The specimen holder was subjected to the heat treatment work for each of the middle part and the surface part in the form of a plate, but the holder was bent while immersed in water, and thus the holder was bent and the round holder was wrapped around the inside as shown in FIG. (5) is the intermediate inner holder using the property that the specimen 1 is metal-cooled from the surface when the specimen (1) is immersed in water by the round processing to be bent to the hot portion due to thermal expansion inside the specimen (1) Based on (4), it was possible to reuse it by preventing bending of the holder when joining and quenching both surfaces as shown in FIG.
