铁渣的

Basing on the the best batch and the best parameters of heat treatment,we mainly investigates the quotiety and quality of deoxidized iron during the course of parent glass preparing according to the characteristic of batch; meanwhile, we discussed the effects of different kinds and contents alkali metal oxid on the glass-ceramic properties,and technics parameters of prepareing the glass-ceramic composite tube by centrifugal molding are also researched originally.

在获得镍渣—粉煤灰微晶玻璃的最佳配比以及最佳热处理制度的基础上，根据配料特点对玻璃熔制过程中铁的还原效果及还原质量进行了分析研究；着重探讨了不同类型、不同含量的碱金属氧化物对微晶玻璃性能的影响；同时也对微晶玻璃复合管的离心制备工艺进行了初步研究。
