| titleOfInvention | Cleaning and tinning process for steel shell |
| abstract | The invention discloses a cleaning and tinning process for a steel shell. The process comprises the following steps: 1) cleaning the steel shell and removing grease; 2) examining and correcting the steel shell; 3) removing oil stains again; and 4) carrying out tinning: (1) preparation before tinning: a, dissolving a mixture of zinc chloride and ammonium chloride mixed according to ratio of 2: 1 in hot water with a temperature of 60 to 70 DEG C so as to prepare a saturated solution, and b, preparing a saturated solution from 32% of zinc chloride, 2.5% of ammonium chloride, 4% of tin chloride and water being the balance; (2) heating of a tinning pot, wherein the steel shell should be preheated at a temperature of 270 to 300 DEG C before tinning, and if preheating temperature is too high, an oxide layer occurs on the surface of the steel shell, bonding is hard to realize during tinning, and even though bonding is barely succeeded, the bonding is not firm; and (3) tinning. The process provided by the invention is simple, omits a great number of repeated procedures and has improved work efficiency. |
