昇温斑が生じ易い等、両方式共欠点があつた。 Known coil continuous heat treatment furnaces include a treatment material roll support type, a catenary type, a floating type, and the like. The roll support method is not widely used due to the problem of damage caused by contact between the treated material and the roll surface, and the catenary method cannot be expected to improve productivity due to tension problems due to the weight of the treated material in the furnace and limitations on the furnace length. In addition, in the floating method, it is difficult to control the floating of the treated material and the jet gas for heating and cooling, and the strip thickness
If the thickness is less than 0.1 m/m, heat treatment becomes difficult. Also, the unit tension in the heating furnace is 0.07Kg/mm 2 ~ 0.1
Although it is desirable to carry out heat treatment at a temperature below Kg/mm 2 , it is extremely difficult to control. In addition, both methods had drawbacks, such as the tendency to cause heating unevenness in the width direction of the treated material.

とはない。 If the operation is carried out as described above, the materials to be treated in the furnace will be transferred to the lower metal belt conveyor 1 in both heating zone A and cooling zone B.
Since the unit tension of the treated material is approximately 0 kg/ mm2 , the thermal strain of the treated material as it is heated and cooled will be lower than that of the metal belt conveyor 11, 31. Since the process is carried out by freely and naturally changing the shape of the treated material, the planar shape of the treated material does not change and become wrinkled.

生を防止して処理材を冷却帯Ｂへ移送する。 In the heating zone A, the lower metal belt conveyor 11 is running with sufficient tension applied by the tension roller 21, but the upper pass line section stably supports the metal belt's own weight due to the pressure generated by the hot air jetted from the hot air patch 13. Because of this, it travels horizontally, and the material to be processed is placed statically and transported with a unit tension of 0 kg/mm 2 . Further, the upper metal belt conveyor 12 runs under sufficient tension by the tension roller 22, and at the lower pass line section, due to the pressure generated by the hot air blowing out from the hot air patch 14,
It is pressurized stably and runs at the same speed as the lower metal belt conveyor 11, in close contact with the processing material without interfering with the movement of the processing material due to temperature increase and strain change. The upper and lower metal belt conveyors 11 and 12 are equipped with heaters 15 and 1, respectively.
6, the temperature is soaked to a predetermined temperature, and the hot air part 1
Metal belt conveyor 1 is heated by hot air from 3 and 14.
1 and 12, and correct temperature unevenness on the metal belt conveyors 11 and 12. Therefore, the material to be processed is transferred to a metal belt conveyor 11 which has been soaked and heated.
Since the temperature is raised by contact with 12, there is no uneven temperature rise,
Heating is performed at a uniform temperature. The treated material that has passed through the heating zone A and has been heated to a high temperature may be transferred to the cooling zone B through a direct passage 23 to the cooling zone B, or may be transferred to the cooling zone B depending on the material, thermal strain mode, heat treatment conditions, etc. It is then transported to the heat treatment strain interference zone C. The heat treatment interference zone C absorbs the elongation due to thermal strain of the treated material that occurs in the heating zone A and the shrinkage change that occurs in the cooling zone B, and absorbs the influence on the treated material.
The running posture is corrected by the pressure generated by the air ejected from the part 25, and the rotation of the drive pulley 19 is controlled by the installed sensor 26, preventing the occurrence of temperature rise distortion and transferring the processing material to the cooling zone B. do.

The metal belt conveyors 31 and 32 are uniformly cooled by coolers 35 and 36, respectively, and heated by the temperature of the material to be processed by the cold air from the cold air parts 33 and 34.
It seems that the temperature is lowered and the cooling is uniform.

are sufficiently tensioned by tension rollers 41 and 42, respectively, and the metal belt conveyor 31 at the upper pass line portion of the lower metal belt conveyor 31 is heated by the pressure generated by the cold air blowing out from the cold air part 33. Because it supports its own weight and is stable, it travels horizontally, and the material to be processed is placed statically at a unit tension of 0 kg/mm 2 and transported. Further, the upper metal belt conveyor 32 runs under sufficient tension by the tension roller 42, and is stabilized under pressure at the lower pass line section by the pressure generated by the cold air blowing out from the cold air part 33, and the lower metal belt conveyor 31, etc. It runs at high speed, in direct contact with the treated material, without interfering with the changes in temperature and strain of the treated material. Therefore, the material to be treated is cooled in contact with the thermally cooled metal belt conveyors 31 and 32, so that it is uniformly cooled without any cooling spots.
