To provide a molten metal furnace capable of being reduced in weight, further, easy in maintenance and capable of reducing a furnace repair construction period.SOLUTION: Provided is a holding furnace 1 comprising: a holding chamber 2 holding a molten metal 10 obtained by melting aluminum in a melting furnace; and a plurality of lining materials 3a to 3g provided at an inner wall 2a of the holding chamber 2 and made of a thermal insulation material. Among the plurality of lining materials 3a to 3g, the lining material 3a provided at a face in contact with the molten metal 10 is made of a ceramic fiber-containing thermal insulation material 11, the lining materials 3b to 3g other than the lining material 3a made of the ceramic fiber-containing material 11 are made of a calcium silicate-containing thermal insulation material, the face of the thermal insulation material 11 in contact with the molten metal 10 is laminated with a talc-containing non-penetration material 12 to which the molten metal 10 is hard to be penetrated, and the face laminated with the non-penetration material 12 is further laminated with a refractory material 13.SELECTED DRAWING: Figure 1
【課題】軽量化することができるとともに、メンテナンスが容易でしかも炉修工期を短縮することができる溶湯炉を提供する。【解決手段】保持炉１は、溶解炉においてアルミニウムを溶解した溶湯１０を保持する保持室２と、保持室２の内壁２ａに設けられ、断熱材料からなる複数の内張材３ａ〜３ｇと、を備えている。複数の内張材３ａ〜３ｇのうち、溶湯１０に接する面に設けられる内張材３ａが、セラミックファイバを含む断熱材１１からなり、セラミックファイバを含む断熱材１１からなる内張材３ａ以外の内張材３ｂ〜３ｇが、ケイ酸カルシウムを含む断熱材料からなり、断熱材１１の溶湯１０に接する面には、溶湯１０が浸透し難いタルクを含む非浸透材１２が積層され、非浸透材１２が積層された面に耐火材１３がさらに積層されている。【選択図】図１
