"¦j" LJagaJ POLSKIEJ RZECZYPOLITEJ PEOPLEJ PATENT DESCRIPTION 346 Z 4S / 0o KI 34 — c; 7/03 Huta "Zabrze" Przedsiebiorstwo Panstwowe Wyodrebowane *) No. 38246 Zabrze. Poland The method of manufacturing molding supports The patent lasts from 20 September 1954. Molding supports intended for fixing cores in foundry molds have the shape of posts with two plates riveted at the ends perpendicular from thin sheet metal. In order to protect the supports against corrosion and to ensure their tight connection to the casting, they are tinned. The invention consists in that the columns of the supports of the given dimensions are obtained by cutting them from steel rods using with mechanical shears, and then both sides are joined with plates by spot welding. Corrosion protection and tight connection of the material of the support with the casting is achieved by paissivating the surface of the supports, thanks to which tinning becomes completely unnecessary. *) The owner of the patent declared that The authors of the invention are: MSc Adolf Wielki and Brunon Chmiel. In order to create protective layers The raw supports are degreased and etched in an aqueous solution of hydrochloric or sulfuric acid heated to a temperature of about 60 ° C. After rinsing in water, the wire brush is removed, remaining scales and dirt are removed, and then acid residues in the milk are neutralized. limestone. After rinsing in water, the supports are immersed in a solution of sodium or potassium dichromate heated to 100 ° C for about 20 minutes to form a protective coating. After the final rinsing and drying, the supports are ready for use. PL
