に断熱ダンパー１２を介して連通している。 In the figure, 1 indicates a continuous heating furnace, which consists of a preheating/heating zone 2 and a soaking zone 3. A groove-type conveying roller 4 is installed at the bottom of each zone, and a pair of left and right side rollers are installed at the ceiling. A guide rail 5 is provided, and a scale discharge opening 6 is provided in the hearth. The opening 6 is connected to a water seal trough 11 provided at the bottom of the furnace body.
is communicated with via an insulating damper 12.
したがつて、搬送ローラ４により炉内搬送され

その上端部が位置決めされ、転倒することなく直
立状態で搬送されることになる。 Therefore, the upper end of the slab W transported into the furnace by the transport rollers 4 is positioned by adjusting the elevation of the guide rail 5, and the slab W is transported in an upright state without falling over.
また、予熱・加熱帯２の側壁の一部は炉幅方向
に突出し、この突出した炉側壁部７に、軸流バー

スロート部７にはサイドバーナ８ａが設けてあ
る。 Further, a part of the side wall of the preheating/heating zone 2 protrudes in the furnace width direction, and an axial flow burner 8 is provided on this protruding furnace side wall portion 7 toward the furnace charging port 1a, and
The throat portion 7 is provided with a side burner 8a.
一方、均熱帯３の炉壁には、サイドバーナであ

ナ９ｃはスラブＷの下面を加熱するものである。 On the other hand, on the furnace wall of the soaking zone 3, radiation burners 9, which are side burners, are provided at the upper and lower portions of the conveyance rollers 4, respectively. Reference numeral 10 denotes a partition wall that divides the soaking chamber R into upper and lower sections, and allows the temperature of the two chambers R 1 and R 2 to be controlled by adjusting the combustion amount of the radiant burners 9a and 9b. Moreover, the side burner 9c heats the lower surface of the slab W.
前記構成からなるため、スラブＷは、予熱・加
熱帯２では軸流バーナで、均熱帯３ではサイドバ
ーナ９により加熱されるものである。 With the above configuration, the slab W is heated by an axial burner in the preheating/heating zone 2 and by a side burner 9 in the soaking zone 3.
