The commercial-scale test shows that the oxygen-enriched air blowing has opened up a new way to higher output of blister copper under the existing conditions.

工业试验表明，富氧吹炼开辟了一条在现有条件下提高粗铜产量的新途径。

Blister copper can be produced directly from standard copper concentrates using a cyclonic reactor operating at 1 500~1 600 ℃ with pure, technical oxygen.

在使用纯工业氧将温度控制在1500￣1600℃的情况下，用旋涡反应器可直接从标准铜精矿生产出粗铜。

The simulation test show that the main controlling targets which were calculated by the fuzzy controller, including grade of blister copper, components of slag and temperatuere, were compared with industrial data and they agree well.

通过模拟实验可看出，主要控制目标粗铜品位、炉渣成分、温度，其模拟值与生产实际分析值比较接近，偏差不大，表明模糊控制器的控制精度较高，能够较好地控制自热炉的生产，稳定炉子的作业状况，模糊控制器的设计是可行、可靠的。

This paper describes briefly necessity of improvement of smelting process in Jinchang Smelter,proves that the blister copper production is better to be fixed at 60000-70000t/a after medification from point of view of heat balance of blowing and gas treating capacity of acid - making system and proposes a way to exploring potential in blister copper production capacity in the future.

本文简述了金昌冶炼厂熔炼工艺改造的必要性，从转炉吹炼的热平衡、制酸系统处理烟气能力等方面论证了改造后粗用规模以60－70kt／a为宜，并简要提出今后粗铜能力挖潜途径。

High-arsenic concentrates can be smelted to white metal in a cyclonic reactor, and the solid ground white metal be converted to blister copper in a second cyclonic unit.

在使用纯工业氧将温度控制在1500￣1600℃的情况下，用旋涡反应器可直接从标准铜精矿生产出粗铜。

The operating results have demonstrated the flexibility of the process in producing blister copper from a variety of copper feed materials including a combination of molten and solid copper matte, reverts and fluxes.

操作结果证明该工艺适用于从各种铜原料(包括熔融冰铜、固体冰铜、返料和熔剂的混合料)生产粗铜。

The oxygen autogenous smelting process of nickeliferous copper concentrate from Jinchuan Nonferrous Corp.

结果表明，含镍铜精矿自热熔炼，可实现除铁、脱硫、保镍，生产含铜90％的粗铜，并减少镍的循环。
