Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to fi used for melting aluminum ingots, scraps, and the like.

Conventionally, stationary melting furnaces include open-well melting furnaces and top-charge or side-charge melting furnaces, which are used depending on the type of melting efficiency *S1.

By the way, in the conventional open-well type melting furnace 1 shown in FIG. 1, the material W is charged from the open-well portion 2 and is melted and dried by the heat retained in the molten metal. However, in this melting furnace 1, since the molten metal is directly exposed to the outside air, there is not only a lot of metal oxidation but also a drawback that heat loss is large.

one! In addition, the introduced Souwa is not completely immersed in the molten metal, and if the material melts, the crystallinity of the molten metal in that part decreases and dries out, so it has to be picked up and stirred by a 4V stirrer, making the work cumbersome. However, it was also dangerous because it required only one sword and one stir to dry, which had the disadvantage that metal oxidation and heat loss increased accordingly.

Furthermore, as mentioned above, top-charge melting furnaces are used depending on the type of material, which has the disadvantage that at least two types of melting furnaces are required to melt all types of metal materials. was.

In order to eliminate the above-mentioned drawbacks of the conventional technology, the uninvented invention is designed to divide the interior into a front chamber and a rear chamber by a lowering type partition wall, and also has an opening/closing door and a lowering type in the front chamber. The metal melting furnace is equipped with a forced immersion stirring device to eliminate the drawbacks of the conventional oven-well type melting furnace, and the rear chamber of the melting furnace is configured as a top charge or side charge type melting chamber. The aim is to provide a non-metal melting furnace that can melt and dry almost all metal materials.

Therefore, according to the first aspect, which is an embodiment of the present invention, the poem H
1, I-J-ru.

The 21st construction shows the first invention, and the furnace main body 10 as a whole has a sealed 1 degree structure, and the inside of the elevating partition wall 111 is connected to the front chamber from the front chamber] 2 and the conventional open well melting method. The rear chamber 13 is the same as in the furnace V, and the front chamber 12 is equipped with an opening/closing door J4 and an elevating forced immersion stirring device 15 on the ceiling, making the front chamber 12 an immersion melting chamber. 8. In the figure, there are 16 burners, 17 is one for cleaning, 8 is a flue, and the rear chamber j3 is equipped with hot water L1 (not shown).

For operation, open the door 14 and put the material ]::1 into the dipping melt f1F u(il "chamber)" 2, then open the door 1.
4 is closed, the forced immersion stirring device fft] and 5 are lowered, and the dissolution is carried out by providing stirring and forcible immersion into the molten liquid in the charging medium.

FIG. 3 shows the second invention, and shows the rear chamber 13 in the first invention.
The ceiling part is a ceiling cover 19 that can be opened and closed, and the rear chamber 13 is a one-tub charge type melting chamber. However, the rear chamber 13 may be a side charge type melting chamber.

Therefore, in the second invention, not only can the ceiling cover 19 be used in the same manner as in the first invention, but also depending on the type of material.
It can be used as a Totsubuchi At-shi type melting furnace in which materials are introduced by opening, or as a Zyde charge type melting furnace.

As is clear from the above explanation, the first invention is the same type as the conventional open-well melting furnace, but
Since the open well part has a closed structure equipped with a stirring device, the molten metal is rarely exposed directly to the outside.

Therefore, it is possible to reduce metal oxidation and heat loss, and since the stirring and immersion of the input materials are performed mechanically, the stirring action is complete, the melting time can be shortened, and the stirring work can be done at 4°V. It's safe.

In the second invention, not only does it have the effects of the first invention described in bll, but also the top charge type or the
- Since it is also possible to perform double-type melting, one melting furnace can be used to melt various materials, and the number of installed melting furnaces can be reduced compared to conventional ones, thereby improving operational efficiency and quality.
