The invention relates to a method for manufacturing brass widely used as conductive element in ore-smelting electric furnace equipment in enterprises producing metallic silicon, ferrosilicon, calcium carbide and the like. The whole production technique mainly comprises the steps of adding trace lithium salt in red copper in melting and casting semicontinuously, hot rolling in set dimension, roughprocessing the blanks, drilling cooling deep holes, cold pressing and shaping, assembling into a whole, testing the finished product, etc. Cathode pure copper is selected as raw material compulsorily; deoxidation is carried out in melting to ensure the casting blank to be anaerobic copper ingot, and trace lithium salt is added, after casting and crystallizing, the compactness, corrosion resistance, high temperature resistance, abrasion resistance, impact resistance, hardness, electrical conductivity and thermal conductivity of the copper product are improved; the hot rolling process smashes bulky arborization crystal to cause crystalline grains to be thin, the fiber structure is continuous with being cut off the mechanical property, electrical conductivity and thermal conductivity are vastly enhanced; water holes are cooled by deep hole drilling machine processing; a press is used for performing cold pressing to roll the blank into arc shape; a boring machine and other equipments are used for boring out required cambered surface radius, electrical conduction joint parts and brass propping parts; and finally the parts are assembled into a whole, and the product is warehoused after passing the test.
