Tin smelting, refining, tin, tin fuming, tin electrolysis, electrical machinery and equipment manufacturing industry: Cable tin. Electronics and telecommunications equipment manufacturing industry: circuit substrate sintered components lining of tin, soldering components, parts manual welding. Job Maintenance: You must work in a ventilated environment solder operations, such as temporary work in the same place means the best fan. Pewter fusion preparation and precautions sequence: production of tin-lead solder alloy should be cast lead, 350 ℃ -400 ℃ temperature when reinvested tin. Ensure maximum reach stirring effect to remove impurities. Depending on the size of solder furnace uses, stirring 20-30 minutes the two sides to carry on (in this case required some able to bring the effect of removing the dross solder material supply, sulfur, sawdust solder purchase, charcoal, etc.) After stirring for 40 minutes, stirring was stopped, the temperature inside the furnace insist on the furnace alloy stand; stand for 20 minutes after the start to remove impurities and then stirring every 10 minutes or so, positive and negative direction each time.
