磷铜合金是熔制铜合金时常用的脱氧剂。过去我厂熔化磷铜是将紫铜刨（或车）成末状，然后将磷、铜末、苏打粉三者按比例用水混合，贴在坩埚边上，上面覆以苏打粉，在坩埚上放好黄泥条，用中间带孔的生铁板压紧，先用慢火烘干，再放入炉中熔化。由于水蒸汽不好控制，坩埚经常烧? Phosphor copper alloy is commonly used when melting copper alloy deoxidizer. In the past, our factory melted phosphor bronze and put the copper planer (or car) into the final shape. Then the three kinds of phosphorus, copper powder and soda powder were mixed with water according to the proportion, attached to the edge of the crucible, covered with baking soda powder and placed on the crucible Good yellow noodles, pressed with a hole in the middle of the iron plate, first with a slow fire drying, and then into the furnace melting. Due to poor steam control, the crucible often burn?
