摘要： A refining means for obtaining high duty spheroidal graphite cast iron through heating molten pig iron in an arc furnace to above the decomposition temperature of silicon oxide in the presence of carbon, such as 1500 DEG C, whereupon a refining agent containing quick lime, graphite powder, calcium silicate, and calcium carbonate is allowed to react in refining through deoxidation and de-sulphurization.

摘要： PURPOSE:To obtain an abrasion-resistive cast iron member having a long service life at low cost by cast-enclosing the porous ceramics at the part where the local abrasion is easily generated on a cast iron pipe for transporting the powdered material. CONSTITUTION:A part 1a positioned outside in the curved direction in the inlet side curved part for the powdered material of a curved pipe 1 made of bainite ductile cast iron and a part 1b positioned inside in the curved direction in the outlet side curved part are made thick, and each plate-shaped porous ceramics 2 having a continuous gas hole is cast-enclosed at these positions. The abrasion in the transport of the powder material through the curved pipe 1 proceeds in the bainite ductile cast iron member inside, bainite ductile cast iron member introduced into the hole part of the porous ceramics 2, and the powdered material introduced into the hole part of the porous ceramics 2. The contact phenomenon of the powdered materials is repeated until the porous ceramics 2 is completely worn out, and the porous ceramics 2 itself is hardly worn out. Therefore, the abrasion resistance is improved, and the service life is prolonged, and the manufacture at low cost is enabled.

摘要： PURPOSE:To prevent the deterioration in the fluidity and corrosion resistance of a formed alloy in the case of producing a composite pipe by using a centrifugal thermit method by specifying the weight ratio of the amt. of the Al to be added in a thermit material and the theoretical amt. of the Al to be added to reduce a metallic oxide. CONSTITUTION:The weight ratio W/Wo between the amt. W of the Al to be added into the thermit material 2 and the theoretical amt. Wo of the Al to be added to reduce the metallic oxide in the material 2 is specified to
