本考案は製鉄機械の焼鈍炉の加熱帯に使用する
ラジアントチユーブの改良に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a radiant tube used in a heating zone of an annealing furnace of a steel making machine.

As shown in FIG. 2, for example, the conventional technique involves tightly fitting the flange 12 of the radiant tube 4 to the flange 2 of the heating furnace casing 1 via a packing 3 at the joint between the radiant tube 4 and the heating furnace casing 1. Then, the lid 5 with the electric heater terminal 7 is fastened and fixed to this with several bolts 6, and the radiant tube 4 is fixed to the heating furnace casing 1, and the H 2 filled inside the furnace does not leak out of the furnace. It was a structure.

However, with the conventional technology, if the electric heater inside the radiant tube breaks midway, the flange fixing bolts 6 must be removed when replacing it, and as a result, the H 2 filling inside the furnace body must be removed.
There is a risk that H 2 may leak outside, which is extremely dangerous, so the furnace must be shut down and the H 2 inside the furnace body
It was necessary to extract all of the heat to a container or the like outside the furnace and then replace the electric heater, which required a great deal of time and effort.

The present invention is proposed to solve the problems of the conventional technology, and is characterized by providing a lid with an electric heater terminal having a smaller diameter than the outside diameter of the radiant tube on the flange end face of the radiant tube that houses the electric heater. It is a radiant tube.
すなわち、本考案では、電熱ヒータ端子が一体

In other words, in the present invention, the lid with the integrated electric heater terminal is fixed to the radiant tube with a lid fixing bolt that is different from the flange fixing bolt, so it is not necessary to remove the flange fixing bolt when replacing the electric heater. It's gone.

The figure is the same as FIG. 2 except for the shape and dimensions of the lid 5 and the method of fixing it. At the joint between the radiant tube 4 and the heating furnace casing 1, the flange 12 of the radiant tube 4 is fixed to the flange 2 of the heating furnace casing 1 via the packing 3 with several flange fixing bolts 6, and the radiant tube 4 is fixed. It is fixed to the heating furnace casing 1. Further, a small lid 5 with an integrated electric heater terminal 7 is directly fixed to the flange portion 12 of the radiant tube 4 with a lid fixing bolt 11.

Since the lid integrated with the electric heater terminal is attached to the radiant tube with a lid fixing bolt different from the flange fixing bolt, there is no need to remove the flange fixing bolt when replacing the electric heater. Therefore, the electric heater can be replaced without the H 2 filling the inside of the furnace body leaking to the outside.
