THE STUDY OF MOLTEN ZINC INTERACTION ON THE SURFACE OF REFRACTORIES IN THE PRODUCTION OF ZINC OXIDE
Journal Title: Materials Engineering - Materialove inzinierstvo (MEMI) - Year 2013, Vol 20, Issue 2
Abstract
This paper is closely connected with the complete process of indirect production of ZnO as well as with the problems which occur during the metallurgical process. Purity of raw materials has an important influence on the final quality of ZnO and the occurrence of slag that remains stuck on the walls of furnace linings. ZnO is generally produced in the melting furnaces with different types of ceramic linings. Input materials have to be analyzed and investigated in the order to the predict behavior from the aspect of the complex production process. Moreover, analysis of occurrence of undesirable phases in the batch, the output materials, character of furnace linings and waste material have to be evaluated and observed. Mutual interaction of all components will have a significant impact on the final quality of the ZnO. The result of the investigation of interaction occurring in the components will be used for the proposal of the suitable surface for furnace lining while the mentioned result is mainly obtained on the principle of chemical reactions and bonds. This surface for lining should have a minimum adhesion of the zinc and its alloys relating to production of ZnO.
