Definitions

  • the coating materials contain e.g. Clays, talc, quartz, mica, zirconium silicate, magnesite, aluminum silicate and chamotte.
  • coke and graphite can also be used as inorganic raw materials. These raw materials are the intended portion of the form coating; they cover the mold surface and close the sand pores against the penetration of the casting metal.
  • the surface roughness of the castings was measured on the surfaces in the mold box below.
  • the measurements were carried out with a roughness depth measuring device, model M4 from Microtechnik, Liederbach.
  • the roughness was measured five times on each casting, and the averaged roughness (Rz) was calculated from the measured values.
  • the mold box from which gaseous pollutants are emitted after pouring, was surrounded by a cuboid metal hood, which had an opening at the top for introducing the measuring lines.
  • the metal hood was immediately after the Pouring over the molding box. By attaching the hood, the exhaust gases could be measured from a homogeneous, continuously changing gas atmosphere.
