Iron Mag blocks. (Metalcasting Supplies).Glo Iron Mag blocks from Globe Metallurgical met·al·lur·gy n. 1. The science that deals with procedures used in extracting metals from their ores, purifying and alloying metals, and creating useful objects from metals. 2. , Inc., can be substituted for silicon-free magnesium additions in ladle treatment of ductile iron Ductile iron, also called ductile cast iron or nodular cast iron, is a type of cast iron invented in 1943 by Keith Millis[1]. While most varieties of cast iron are brittle, ductile iron is much more ductile, as the name implies. . The blocks also can be used for over treatment in conjunction with automatic pouring of ductile iron to rejuvenate re·ju·ve·nate tr.v. re·ju·ve·nat·ed, re·ju·ve·nat·ing, re·ju·ve·nates 1. To restore to youthful vigor or appearance; make young again. 2. the low residual magnesium iron in the auto pour/ladle treatment. They can be used in the overpour, sandwich, tundish tun·dish n. 1. A funnel. 2. A container for pouring molten metal into a mold, having holes in the bottom to prevent splashing. or plunging processes by itself or in conjunction with magnesium ferrosilicone. Using these blocks allows a greater proportion of foundry returns to be melted, permits control of final silicon to lower levels, reduces sulfur and increases residual magnesium without affecting the silicon, and serves as an alternative to nickel-containing nodularizers. The blocks are produced from blends of high purity iron and magnesium powders. The powders are mixed using a binder binder: see combine. An earlier Microsoft Office workbook file that let users combine related documents from different Office applications. The documents could be viewed, saved, opened, e-mailed and printed as a group. to minimize segregation and provide strength. Pressing the mix to a specific pressure creates cylinder-shaped blocks. The organic binder burns off completely during ladle filling without leaving residue or slag in the molten metal or ladles. The blocks are available in 2 and 3-in-diameter sizes weighing 0.5-1 lb with 10 and 15% magnesium content by weight. Globe Metallurgical, Inc. Select No. 005 at www.moderncasting.com/info. |
