This bypass molten metal contains nonmetallic inclusions such as metal oxides, coarse intermetallic compounds, and inorganic particles generated from furnace materials, so it is mixed into the ingot as it is and is rolled to form thin plates, foils, etc. When manufactured, it causes hard spots and surface defects. Therefore, a ceramic fiber packing 15 is used in the insertion hole 7 of the left side plate 3, and it is fixed with mortar 16 which has a certain degree of deformability under high temperatures.
