Расплавленный металл литье Фильтрация Диски

Molten metal casting filtering disk is a very effective molten metal filter, and is made of mullite ceramics. It uses quality high-density straight-pore meshes, and has high thermal impact resistance and high resistance to casting temperature. The straight-pore design ensures good balance between flow rate and strength. These design features will completely remove impurities and slag from molten metal, obviously improve mechanical functions, mechanical performances, appearance quality and fitness ratio of castings, while reducing operation cost.Specifications: 1) Material: mullite 2) Chemical composition: Al2O3 content 53-63%,SiO2 content 35-40% 3) Cold state compression strength: ≥18MPa 4) Loaded flame resistance: ≥1,485oC 5) Flame resistance: ≥1,680oC 6) Water absorption: 16%-18% 7) Reheating linear shrinkage: 0.2% (1,500oC) 8) Tolerance of outside dimensions: ±1% mm (section), ±0.5mm(thickness)
