开发新的制团工艺是实现硫化锌精矿直接还原蒸馏无污染冶金新工艺的关键技术之一．本文的研究结果表明，采用热压制团工艺以３８ＭＰａ的压力可制备出抗压强度达４３．５ＭＰａ的生团矿．热压制团工艺的最佳预热温度为４５０～５００℃，时间约５ｍｉｎ．最后，探讨了热压成型的机理．
The development of a new process is to achieve the system of zinc sulfide concentrate direct reduction distillation of non-polluting metallurgical new technology, one of the key technologies. The results of this study show that the hot compaction process can be 38MPa pressure can be prepared with a compressive strength of 43.5MPa raw pellets. The optimum preheating temperature of hot pressing process is 450 ~ 500 ℃, the time is about 5min. Finally, the mechanism of hot forming is discussed.
