Description
本発明の金属溶湯濾過装置は、金属溶湯を貯留する貯留部に横向きの多孔質セラミックスチューブを配した金属溶湯濾過装置において、貯留部内に貯留した金属溶湯に浸漬する浸漬部を、装置を被覆する蓋部に設けたことを特徴とする。 The metal melt filtration device of the present invention is a metal melt filtration device in which a laterally oriented porous ceramic tube is arranged in a storage portion for storing a metal melt , and covers the immersion portion immersed in the metal melt stored in the storage portion. It was provided in the cover part .
本発明の金属溶湯濾過装置は、浸漬部を設けたことにより、貯留部の金属溶湯の容量を減少させることができ、残湯量を減少させることができる。さらには、金属溶湯の湯面が大気中の酸素に接触する面積が減少するため、金属溶湯の酸化を抑制することができる。この結果、鋳造に用いられる溶湯の分量を増やせると同時に、廃棄する金属酸化物の量を抑制し、溶湯の歩留まり向上と省資源化を図ることができる。
また、浸漬部は、金属溶湯の湯面上部の大気の対流によって熱が奪われるのを防ぐ効果がある。
Since the molten metal filter device of the present invention is provided with the immersion part , the capacity of the molten metal in the storage part can be reduced, and the amount of remaining hot water can be reduced. Furthermore, since the area where the molten metal surface of the molten metal comes into contact with oxygen in the atmosphere is reduced, the oxidation of the molten metal can be suppressed. As a result, the amount of the molten metal used for casting can be increased, and at the same time, the amount of the metal oxide to be discarded can be suppressed to improve the yield of the molten metal and save resources.
In addition, the immersion part has an effect of preventing heat from being taken away by convection of the atmosphere above the molten metal surface.
蓋部3は、装置全体を覆う板状の被覆部8と、貯留部5内に貯留する金属溶湯の容量を減少させるように貯留部5の上方部分を占める浸漬部9と、備えている。 The lid portion 3 includes a plate-like covering portion 8 that covers the entire apparatus, and an immersion portion 9 that occupies an upper portion of the storage portion 5 so as to reduce the capacity of the molten metal stored in the storage portion 5.
本実施形態では、被覆部8と浸漬部9とを一体的に形成してあるが、別体に形成することもできる。 In the present embodiment, the covering portion 8 and the immersion portion 9 are integrally formed, but can be formed separately.
浸漬部9は、アルミニウムと反応しにくい耐火物から形成してあり、より具体的には、窒化珪素結合SiCセラミックス、窒化珪素系セラミックス、アルミナ−シリカ系セラミックス、ジルコン系セラミックスのいずれかから形成することができる。 The immersion part 9 is formed of a refractory that does not easily react with aluminum, and more specifically, is formed of any one of silicon nitride-bonded SiC ceramics, silicon nitride-based ceramics, alumina-silica-based ceramics, and zircon-based ceramics. be able to.
浸漬部9は、被覆部8の底面を逆台形状に膨出させ、貯留部5の内壁に沿うように形成してあり、入湯口付近を残して、貯留部5の上方部分を隙間なく塞ぐことができる。その下端面9aは、入湯口4の底面4aよりも下方に位置するようにしてある。具体的には、底面4aから1mm以上下方、好ましくは1mm〜500mmで、チューブ6の上端より5mm〜100mm上方に位置するのが好ましい。これにより、浸漬部9が溶湯中に浸漬し、貯留部5に貯まる金属溶湯の容量を減少させることができる。なお、装置1の稼働時において、底面4aと貯留部5に貯めた金属溶湯の湯面とは略同じ高さになる。
本実施形態では、浸漬部9を、貯留部5の上方部分を隙間なく塞ぐように形成してあるが、これに限定されるものではなく、装置稼働時において閉塞部が金属溶湯中に浸漬するように形成してあれば、貯留部に貯まる金属溶湯の容量を減少させることができ、残湯量を減少させることができる。
The immersion part 9 bulges the bottom surface of the covering part 8 into an inverted trapezoidal shape and is formed along the inner wall of the storage part 5, and closes the upper part of the storage part 5 without leaving a gap, leaving the vicinity of the hot water inlet. be able to. The lower end surface 9 a is located below the bottom surface 4 a of the hot water inlet 4. Specifically, it is preferably 1 mm or more below the bottom surface 4 a, preferably 1 mm to 500 mm, and 5 mm to 100 mm above the upper end of the tube 6. Thereby, the immersion part 9 is immersed in the molten metal, and the capacity of the molten metal stored in the storage part 5 can be reduced. In addition, when the apparatus 1 is in operation, the bottom surface 4a and the molten metal surface stored in the storage unit 5 have substantially the same height.
In this embodiment, although the immersion part 9 is formed so that the upper part of the storage part 5 may be plugged up without gap, it is not limited to this, and the blocking part is immersed in the molten metal when the apparatus is operating. If it forms in this way, the capacity | capacitance of the molten metal stored in a storage part can be reduced, and the amount of remaining hot water can be reduced.
このような濾過装置1は、浸漬部9により、貯留部5に貯まる金属溶湯の容量が従来と比較して減少するため、残湯量を減らすことができる。 Such a filtering device 1 can reduce the amount of remaining hot water because the capacity of the molten metal stored in the storage unit 5 is reduced by the immersion unit 9 as compared with the conventional case.
さらには、浸漬部9を設けたことにより、金属溶湯が酸素に触れにくくなるため、濾過処理中に金属溶湯が酸化されにくくなり、濾過した金属溶湯中に含まれる酸化物の量が従来比約60〜80wt%減少させることができる。 Furthermore, since the molten metal is less likely to come into contact with oxygen by providing the immersion part 9, the molten metal is less likely to be oxidized during the filtration process, and the amount of oxide contained in the filtered molten metal is about It can be reduced by 60 to 80 wt%.
