MgO型气保护药芯焊丝渣覆盖的研究

A Study on Slag Covering Ability of Basic Gas-shielded Wire with MgO Based Slag System

首先介绍了一种新型的碱性气保护药芯焊丝的渣系,即MgO渣系,描述了该渣系的主要成分及性能,研究了该渣系的各组分对渣覆盖率和渣壳断面形状的影响,分析了各组分及因素对渣覆盖的影响规律.对YHJ507渣覆盖性能的影响因素进行了实验研究.对配方成分及其他因素做了单因子实验,得出了这些因素对YHJ507渣覆盖性能的影响规律.并通过回归分析的方法,得出了配方成分与YHJ507渣覆盖率之间关系的数学模型,这对YHJ507的配方设计具有指导意义.

A new basic type gas shielded flux cored wire slag system-MgO based slag system is introduced in this paper. The main ingredients and their properties are described. The effect of flux ingredients to slag covering ability and slag cross section shape is studied. The principle was analysed. The effect elements of slag covering ability were researched through testing. The effection principle was concluded. And the relation between the ingredients and the slag covering ability was calculated. The mathematical model was established. The conclusion has guiding purpose in flux cored wire developing research.
