摘要： This invention relates to components of ceramic kiln and furnace hardware made of NICRALY alloys.Disclosed is a method of heat treating NICRALY alloys to obtain a uniform film of desired alumina (Al.sub.2 O.sub.3) on the surface of the alloys. The gist of the invention resides in the control of the critical relationship between the temperature and the partial pressure of oxygen in the oxygen potential controlled atmosphere during the heat treatment. Optimum results are obtained when the temperature is about 2100.degree. F. and the dew point is about -30.degree. F. in hydrogen for about one hour.

摘要： An electroslag remelting process for manganese-base alloys. The process includes the steps of: partially immersing a consumable electrode of a manganese-base alloy in a layer of molten slag and passing current between the consumable electrode and a second electrode. The current is passed through the slag layer under conditions which gradually melt the consumable electrode so that drops of molten metal from the consumable electrode move downwardly through the slag layer and resolidify as an ingot thereunder. The slag is characterized by a fusion temperature of more than 300.degree. F. (149.degree. C.), and often more than 350.degree. F. (177.degree. C.), above the melting point of the consumable electrode. It is preferably comprised of Al.sub.2 O.sub.3, CaO and CaF.sub.2.

摘要： A strand annealing furnace is provided with a tube assembly to shield or protect the strand being annealed from the hot furnace atmosphere. The tube assembly includes a long, outer, oxidation-resistant pipe and a shorter, inner easily removable, insert, protecting at least the entrance end of the tube, so that any residue from drawing lubricants will deposit within the insert rather than block and/or corrode the pipe.
