Title: Improvement in salt bath furnaces
IPC: C21D1/46
Filed: 1943-08-04
Abstract: An electric furnace for use with chloride or chloride-fluoride salt baths has a lining of refractory material or bricks which have been impregnated with aluminium hydrate, preferably by soaking the refractory first in aqueous aluminium sulphate or chloride and then in aqueous ammonia, and refired preferably to the temperature at which the refractory was originally fired, and then lined with the chloride, or the predominant chlorides of the bath to be normally used therein.  When the electrolyte consists of a mixture of salts, the bath is filled with the predominant salt, which may be an alkali metal or alkaline earth metal chloride and fused and maintained at a temperature well above that of the melting point of chlorides for 10-48 hours.  Part of this salt is then removed and replaced by the other compound which may be an alkali metal or alkaline earth metal chloride or fluoride. Suitable mixes are 60-90 per cent barium chloride with 40-10 per cent potassium chloride and 50-70 per cent barium chloride with 50-30 per cent calcium fluoride.  The molten salts may be covered with a mixture of 25 per cent silicon carbide and 75 per cent graphite either in flake form or ground to pass a 200 mesh screen. The electrodes are preferably made from 88-92 per cent nickel and 12-8 per cent chromium.

Abstract: A composition for consolidating a permeable mass comprises a solution of resin-forming composition and an "organo functional silane" in a solvent.  The "organo-functional silane" is an organic substance containing a silicon atom, a functional group suitable for reacting with the particles of the mass, and a functional group suitable for reacting with the components of the resin-forming composition or the product formed thereby.  The silane has an amino, epoxy, methoxy or ethoxy group for reacting with the resin-forming composition, and preferably forms at the most 1 vol. per cent of the solution.  The resin-forming composition may be uncured resin such as a polyepoxide having more than one epoxy group <FORM:1019122/C3/1> per molecule and a curing agent such as a polyamine compound containing at least three aminohydrogen atoms, or the polyepoxide and a substance formed by reacting the polyepoxide with a curing agent, or a hydroxyaryl compound and an aldehyde.  When using the polyepoxide the solvent is an alcohol, a mixture of alcohols, an aromatic hydrocarbon, a mixture of aromatic hydrocarbons, or a mixture of aromatic and other hydrocarbons, and when using the hydroxyaryl compound the solution is aqueous. The resin-forming composition is 3-50 vol. per cent of the solution.  The reaction rate of the resin-forming composition is controlled by a ketone, a phenol, water or an alkaline compound such as sodium or potassium hydroxide.
