The invention discloses a mining cable high-strength
oxygen free
copper rod. In the burdening process, electrolytic
copper raw materials are strictly screened, according to selection of
copper, exceptfor the electrolytic copper, a certain amount of red copper waste is added, through refining
impurity removal and deoxygenization, the standard of the
cathode copper
oxygen containing amount can be basically achieved, the problem about using of red copper waste renewable resources can be solved, and production cost is reduced; in the
smelting process, through three-time refining, different refining reagents are selected, through layer-by-layer progressive operation,
impurity metal like
zinc, lead,
tin,
nickel,
arsenic and the like can be removed to the maximum degree, through a composite deoxidant,
lanthanum,
cerium and
praseodymium compound
rare earth elements can be used for obviously improving the process property of the copper, and can make sufficient reaction with cuprous
oxide in melt copper, the cuprous
oxide is sufficiently reduced into copper, the compound deoxidant formed by
calcium hexaboride and
lithium oxide can further reduce the content of
oxygen in the melt copper, andthe product oxygen containing amount can be further reduced.
