一、我国氧化铝生产 走向新的高度 改革开放以来,我国铝工业取得长足的进步,不但产量品种增加,而且质量提高,生产消耗下降。国产铝已基本实现自给,氧化铝缺口也趋向缓觖。铝和氧化铝的生产能力已分别突破了200万吨和300万吨的水平,基本形成了我国铝冶炼的工业体系。国内铝冶炼业的基本情况是:电解铝效益较高,氧化铝效益较低,但两者的生产状况互相影响,工艺流程上两者是上下游关系。氧化铝除作为电解铝的基本原料外,非铝用氧化铝的应用领域也在不断开拓,据报导,目前世界非冶金用氧化铝占氧化
First, China’s alumina production to a new height Since the reform and opening up, China’s aluminum industry has made considerable progress, not only increase the variety of varieties, but also improve the quality, production and consumption decreased. Domestic aluminum has basically achieved self-sufficiency, and the gap in alumina tends to be sluggish. Aluminum and alumina production capacity have respectively exceeded the level of 2 million tons and 3 million tons, basically forming an industrial system of aluminum smelting in China. The basic situation of the domestic aluminum smelting industry is: electrolytic aluminum higher benefit, lower alumina efficiency, but the production of the two affect each other, the two processes on the upstream and downstream relations. Alumina In addition to the basic raw materials for electrolytic aluminum, non-aluminum alumina applications are also constantly open up, according to the report, the current world non-metallurgical alumina accounted for oxidation
