  Air and vacuum investment casting of Cobalt & Nickel alloys

  Casting. After pre-heating the ceramic mold at high temperature, the molten metal is poured inside the mold and then it is allowed to cool and solidify. Deloro Microfusione performs equiax casting, using furnaces in air and vacuum furnaces, with a pouring capability up to 160 kg. The alloys poured are stainless steel and Nickel and Cobalt based ...

  Pachuca Tank - 911 Metallurgist

  2016611 · Pachuca tanks are used for a wide variety of leaching and mixing operations in the minerals industry. Previously, an equation was derived to predict the circulation in a Pachuca tank with full height draft tube risers. This analysis was subsequently verified with data from a large bore air-water flow loop used. However, the …
