过去5年智利国家铜公司特尼恩特分公司卡勒托内斯冶炼厂用于铜精矿自热熔炼的特尼恩特转炉技术经历了一个重要而卓有成效的发展过程. 两台新型的大型反应器(φ5m×22m)取代了分别自1977年和1978年以来投产的两台设备。这里介绍的最重要的技术改进是自1988年6月以来,适用于将干透了的精矿(以下简称干精矿)给入反应器的所谓“精矿浸没熔炼”。目前“熔池熔炼”和“精矿浸没熔炼”技术均在使用中.加入反应器的精矿。55%以上是用气流输送注入的。由于这项技术的开发.增加了自热熔炼的能力.并降低了操作费用. 特尼恩特转炉的热平衡表明.使一定的精矿(按其化学成分)达到连续的熔炼状态而不必添加冰铜是可能的。这种生产系统设置的特尼恩特转炉是铜精矿熔炼和吹炼过程中最有效的设备之一. 本文介绍了近年来的改进、采用“精矿浸没熔炼”技术之后,熔炼能力的预测及特尼恩特转炉的能耗预测。
In the past five years, the Technion converter at the Tyrrenes smelter in Teinte, Chile’s state-owned copper company, has experienced an important and fruitful development of its technology for the teatunter converter for self-heating copper concentrates. Two new large Reactor (φ5m × 22m) replaced two separate units put into operation in 1977 and 1978 respectively. The most important technical improvement introduced here is the so-called “concentrate immersion melting” applied to the reactor to dry the concentrate (hereinafter referred to as “dry concentrate”) since June 1988. At present, “molten pool melting” and “concentrate immersion melting” technology are in use. Joined the reactor concentrate. More than 55% is infused with air delivery. Due to the development of this technology, the capability of self-heating melting is increased and operating costs are reduced, and the heat balance of the Tehntech converter shows that it is possible to bring a certain concentrate (in terms of its chemical composition) to a continuous melting state without adding ice Copper is possible. The Technion converter set up in this production system is one of the most effective equipment for the smelting and blowing of copper concentrates.This paper presents improvements in recent years, the prediction of smelting capacity after “concentrate-immersion melting” technology And Tenente converter energy consumption forecast.
