摘要

对镁铬铁矿产品的质量组分进行了有机添加剂种类的调整。这是用桑德森的电负性和摩尔电负性的概念来完成的。选择了4种有机添加剂，通过全析因试验研究了它们对耐火材料性能的影响。耐火材料的基本性能以7个响应函数的形式表示，其中6个响应函数由统计验证方程描述。最有利的选择是根据材料的六个特征标准选出的。引入有机添加剂作为滑脱剂，导致烧成后镁铬铁矿材料的几乎所有性能都得到改善。证明了添加剂组成的目的性。

Effect of selected organic additives on the properties of magnesia-chromite refractories

An attempt was made to adjust the kind of organic additives to the components of the mass for the magnesia-chromite products. This was done using Sanderson’s concept of electronegativity and molar electronegativity. Four organic additives were selected and their influence on the properties of the refractories was studied by performing a total factorial experiment 24. The basic properties of the refractories are presented in the form of seven response functions, six of which are described by statistically verified equations. The most favourable options were selected on the basis of six criteria that characterise the materials. The introduction of organic additives as slip agents into the mass, resulted in an improvement in practically all properties of the magnesia-chromite materials after firing. The purposefulness of the additive composition was demonstrated.
