、煤が効率よく鋼帯へ付着しない等の問題があった。However, in order to arrange the soot-generating burner in the heating zone, it is necessary to design the soot-generating burner to match the heat treatment furnace. There were problems such as soot not adhering to the steel strip efficiently due to interference from the flow of combustion gas from the heating vane.
これは、第４図に示すように、鋼帯に衝突した煤発生用
バーナの燃焼ガスは、外方へ旋回しながら循環するため
、燃焼ガス温度が下がり、その結果、十分な煤が発生し
ないものと考えられる。This is because, as shown in Figure 4, the combustion gas from the soot-generating burner that collides with the steel strip circulates while swirling outward, resulting in a lower combustion gas temperature and, as a result, not enough soot is generated. considered to be a thing.
したがって、本発明は、煤発生用バーナの燃焼ガスが、

とを目的とする。Therefore, the present invention provides that the combustion gas of the soot-generating burner is
Even if the combustion gas collides with the copper strip, it does not swirl and is discharged out of the furnace as it is to prevent the temperature of the combustion gas on the surface of the steel strip from decreasing, and by flowing it along the steel strip, the above-mentioned problems can be solved. The purpose is to provide a blackening treatment furnace that can solve the problems.

They are disposed with their jet ports facing each other in the width across width direction of the steel strip W. Note that this soot-generating burner 5 is, for example,
A type of fuel that is supplied with 10 to 40% of the amount of oxygen required for complete combustion and performs incomplete combustion.

り熱を有効利用することもできる。FIG. 3 shows a cross section of the blackening treatment furnace 2 according to the present invention in the direction of the inside of the furnace. The combustion gas from the saw soot generating burner 5 installed on the ceiling of the furnace 2 collides with the surface of the steel strip W, and then is discharged by a device consisting of a waste removal pipe 11 and a fan I2 installed on the side of the furnace. Ru. In this case, as shown in the figure, the flame collides almost perpendicularly with the surface of the steel strip W in the central portion thereof, and collides with the surface slightly diagonally at the side portions. This exhaust gas can also be sent to a subsequent continuous heat treatment furnace to effectively utilize the heat.

また、底部にも煤発生用バナ５を配設してもよい。Note that the ceiling of the blackening treatment furnace 2 may be fixed, but it may also be movable up and down so that it can be adjusted to a position where the state of collision of the flame with the steel strip W is optimal.
Further, a soot-generating banner 5 may also be provided at the bottom.
（発明の効果）
以上の説明で明らかなように、本発明の黒化処理炉は、
連続熱処理炉と別体であるから、連続熱処理炉の構成に
左右されず、設計も極めて容易である。(Effects of the Invention) As is clear from the above explanation, the blackening treatment furnace of the present invention has the following features:
Since it is separate from the continuous heat treatment furnace, it is not affected by the configuration of the continuous heat treatment furnace and is extremely easy to design.

器である。Further, the discharge device 7 has one end taken to the outlet 4 of the blackening treatment furnace 2 by the internal force of the communication path 6, and the other end is opened to the person II I a of the continuous heat treatment furnace 1. Consisting of a cylindrical body 8 and a fan 9, air from the fan 9 is ejected into the heat treatment furnace 1 from a passage P formed between the communication passage 6 and the cylindrical body 8, thereby causing blackening. The furnace atmosphere inside the processing furnace 2 is sucked into the heat treatment furnace i. in this case,
Due to the suction effect of the exhaust device 7, the flame from the soot generating bar 5 tends to flow toward the heat treatment furnace 1 side, but the population 3 side of the blackening treatment furnace 2 is almost completely drained due to the introduction of outside air from the inlet 3. Since the pressure is higher than that on the 14th side, the flame on the 113th side collides almost perpendicularly with the surface of the steel strip W, as shown in Figure 2, and the other flames collide slightly obliquely. The combustion gas after soot has been attached is discharged to the continuous heat treatment furnace 1 by the suction action of the discharge device 7 without swirling as described above. It is a heat absorption rate measuring instrument.
つぎに、本発明の別の実施例を第３図により説あり、か
つ、加熱用バ−すの燃焼ガスにも干渉されない。Next, another embodiment of the present invention will be explained with reference to FIG. 3, and is not interfered with by the combustion gas of the heating bar.
