Abstract

939,771. Coating by dipping. NISSHIN SEIKO KABUSHIKI KAISHA. April 21, 1960 [April 22, 1959], No. 14054/60. Class 82. [Also in Group XXII] A stainless steel sheet and a carbon steel sheet are coated and joined by dipping in molten terne metal. A stainless steel sheet 1 is fed from a reel 2 over an elastic roller 8 partly immersed in hydrochloric acid 7, the sheet being held in tension against the roller so that only its lower surface is pickled, the pickled surface is coated with a zinc chloride fluxing solution by rollers 38, 40, the flux is dried by a drier 13 and the sheet then passes to rollers 42 which coat the upper surface with an aqueous suspension of powdered calcium carbonate. The sheet 1 after drying in drier 16 passes into a terne metal (5-30% preferably 10% tin remainder lead) bath 23 at 620-680‹ F. preferably 650‹ F. into contact with a carbon steel sheet 17 fed from a reel 18 into a sulphuric acid bath 20 and through molten zinc chloride 26 on the surface of the terne metal into the terne metal bath, the flux coated surface of the stainless steel sheet coming into contact with the carbon steel sheet. The sheets are passed together through palm, fish or mineral oil 34 in a chamber 37 on the surface of the terne metal between pressing rollers 29, 30. Compressed air jets 32 above the palm &c. oil cool the oil and the now soldered composite sheet which passes through squeeze rollers 31 into a rinsing tank 33 and finally to a reel 44. The two sheets are soldered by the terne metal which also coats the outer face of the carbon steel sheet but is prevented from coating the outer face of the stainless steel sheet by the calcium carbonate coating. The stainless steel may be 18 Co 8 Ni type and the carbon steel may comprise 0.03-0.1% carbon. Non-continuous sheets of steel may be employed in the process.
