温熱源としての浸漬加熱型バーナに関するものである。[Detailed Description of the Invention] The present invention relates to an immersion heating burner as a heat-insulating heat source in a light metal or other metal melting furnace, holding furnace, etc., or an intermediate ladle (tundish for continuous casting).

従来このような用途に用いられる浸漬加熱型バーナの発
熱体部はＵ型、Ｗ型等の管が使用されている。Conventionally, a U-shaped, W-shaped, etc. tube has been used for the heating element of an immersion heating type burner used for such purposes.

この部を構成する材料には主として金属が用いられてい
るが、金属は溶融金属に侵食され、耐用期間が短かい。Metal is mainly used as the material constituting this part, but metal is corroded by molten metal and has a short service life.

この欠点を改良するためには溶融金属に強く、熱伝導度

れらの耐火物は加工性が悪く、複雑な形への加工には困
難があり、使用されても単純な形状のものに限られてい
る。In order to improve this drawback, it is desirable to use refractories such as silicon carbide that are resistant to molten metal and have high thermal conductivity, but these refractories have poor workability and are difficult to process into complex shapes. However, even if it is used, it is limited to simple shapes.

である。In the figure, 1 is a heating element made of a refractory material with good thermal conductivity such as silicon carbide, 2 is a tubular inner hole formed inside the heating element, 3 is a connection port to a gas burner, and 4 is an exhaust gas. It is the mouth.

バーナ本体より流入する高温の燃焼ガスは３より入り、
管状の内孔２の中を発熱体を加熱しつつ通過し、４の排
気口より放出される。The high temperature combustion gas flowing in from the burner body enters from 3.
It passes through the tubular inner hole 2 while heating the heating element, and is discharged from the exhaust port 4.

発熱体は内部より加熱され、外面より被加熱体に熱を伝
達することにより、発熱体としての働をする。The heating element functions as a heating element by being heated from the inside and transmitting heat to the heated body from the outside.

内孔の形状は第１図、第２図の如く、その断面を円型と

ーナ本体、９は空炉昇温用バーナである。Figure 5 shows an example in which the immersion heating type burner according to the present invention is used in a boat-shaped furnace for holding molten aluminum, where 5 is the holding furnace body, 6 is the molten aluminum, 7 is the heating element of the immersion heating type burner, and 8 is the gas burner. The main body, 9, is a burner for heating up the air furnace.

炉は空炉昇温用バーナ９により加熱された後、アルミ溶
湯を受入れ、以後浸漬加熱型バーナにより適度に保温さ
れる。After the furnace is heated by the empty furnace heating burner 9, the molten aluminum is received, and thereafter the temperature is maintained appropriately by the immersion heating type burner.

発熱体の排気口を第３図、第４図に示す如く、上部平面
部に開口せしめることにより、排気は湯面上に排出され
、湯面よりの冷却を防止するのに役立たしめることも可
能である。By opening the exhaust port of the heating element in the upper flat part as shown in Figures 3 and 4, the exhaust gas is discharged above the surface of the hot water, which can also be used to prevent cooling from the surface of the hot water. It is.

本考案に係る発熱体は、例えば対応する面に所要形状の
