전술한 냉각부(50)의 냉각재킷(51) 하부에는 제 1 이동대차(60)가 결합되는데, 이 제 1 이동대차(60)는 피처리물(3)의 분위기 열처리시에 열처리부(40)의 로심관(43)의 열팽창 방향과 동일한 방향으로 냉각부(50)를 이동시키는 역할을 하는 것으로, 가이드레일(61)과, 가이드레일(61)을 따라 주행가능한 휠(63)을 포함한다.The first moving trolley 60 is coupled to the lower portion of the cooling jacket 51 of the cooling unit 50, and the first moving trolley 60 is a heat treatment unit 40 during the atmospheric heat treatment of the workpiece 3. It serves to move the cooling unit 50 in the same direction as the thermal expansion direction of the low-core tube 43 of), and includes a guide rail 61 and a wheel 63 that can travel along the guide rail 61. .

본 고안에 따른 연속식 분위기 열처리장치(1)의 경우에는 제 1 이동대차(60)가 열처리부(40)의 하류에 위치되는 냉각부(50)에 결합됨에 따라, 피처리물(3)의 분위기 열처리시에 분위기로(41)의 로심관(43)이 열팽창되더라도 냉각부(50)가 피처리물(3)의 이동방향과 동일한 방향으로 이동됨에 따라 피처리물(3)의 이동에 대한 저항력이 최소화될 수 있게 된다.In the case of the continuous atmosphere heat treatment apparatus 1 according to the present invention, as the first moving trolley 60 is coupled to the cooling unit 50 located downstream of the heat treatment unit 40, Even when the furnace core tube 43 of the atmosphere furnace 41 is thermally expanded during the atmosphere heat treatment, the cooling unit 50 is moved in the same direction as the movement direction of the workpiece 3, thereby causing the movement of the workpiece 3. Resistance can be minimized.

전술한 구성의 본 고안에 따른 연속식 분위기 열처리장치(1)을 새로 제조하여 사용하는 것이 가장 바람직하겠지만, 제조비용을 절감상 전술한 제 1 이동대차 (60)의 구성을 종래기술에 따른 연속식 분위기 열처리장치(100: 도 1 참조)에 부가적으로 적용하여 사용할 수도 있는데, 이를 위하여 본 고안에 따른 연속식 분위기 열처리장치(1)는 전술한 제 1 이동대차(60) 외에도 예열부(30)의 예열관(31)의 하부에 결합되고 열처리부(40)의 로심관(43)의 열팽창시 예열부(30)를 이동시키는 제 2 이동대차(70)를 더 포함하여 이루어질 수 있다.It is most preferable to manufacture and use the continuous atmosphere heat treatment apparatus 1 according to the present invention of the above-described configuration, but in order to reduce the manufacturing cost, the configuration of the above-described first mobile truck 60 according to the prior art In addition to the atmosphere heat treatment apparatus 100 (see FIG. 1) may be used additionally, for this purpose, the continuous atmosphere heat treatment apparatus 1 according to the present invention is a preheating unit 30 in addition to the first moving trolley 60 described above. The second moving cart 70 is coupled to the lower portion of the preheating tube 31 and moves the preheating unit 30 during thermal expansion of the core tube 43 of the heat treatment unit 40.

제 1 및 제 2 이동대차(60, 70)를 포함하는 구조에서는 피처리물(3)의 분위기 열처리에 의해 분위기로(41)의 로심관(43)이 열팽창될 경우에 예열부(30)가 제 2 이동대차(70)에 의해 피처리물(3)의 이동방향의 역방향으로 다소 이동되기는 하지만, 냉각부(50)가 제 1 이동대차(60)에 의해 피처리물(3)의 이동방향과 동일한 방향으로 이동됨에 따라 피처리물(3)의 이동에 대한 저항력을 감소시킬 수 있게 된다. In the structure including the first and second moving trolleys 60 and 70, the preheating unit 30 is formed when the core tube 43 of the atmosphere furnace 41 is thermally expanded by the atmospheric heat treatment of the workpiece 3. Although somewhat moved in the opposite direction to the moving direction of the workpiece 3 by the second moving cart 70, the cooling unit 50 is moved by the first moving cart 60 in the moving direction of the workpiece 3. As it is moved in the same direction as can reduce the resistance to the movement of the object (3).

이상에서와 같은 본 고안에 따른 연속식 분위기 열처리장치에 의하면, 제 1 이동대차가 열처리부의 하류에 위치되는 냉각부에 결합됨에 따라, 분위기로의 로심관이 열팽창될 경우에 피처리물의 이동방향과 동일한 방향으로 열팽창이 이동되는 관계로 피처리물의 이동에 대한 저항력이 최소할 될 수 있는 탁월한 효과가 있다.According to the continuous atmosphere heat treatment apparatus according to the present invention as described above, when the first moving trolley is coupled to the cooling unit located downstream of the heat treatment unit, when the core tube into the atmosphere is thermally expanded, Since thermal expansion is moved in the same direction, there is an excellent effect that the resistance to the movement of the workpiece can be minimized.

또한 이동대차가 열처리부의 상류에 위치되는 예열부에 결합된 종래의 연속식 분위기 열처리장치에도 적용될 수 있는 부가적인 효과가 있다.There is also an additional effect that the mobile bogie can be applied to a conventional continuous atmosphere heat treatment apparatus coupled to a preheating portion located upstream of the heat treatment portion.
