【摘要】 运用均匀设计的方法,将药皮敷料作为自变量,焊缝的脱渣性作为目标函数,探讨了药皮敷料对不锈钢焊条脱渣性的影响,给出了二者间的关系曲线;根据计算分析结果,研究了对焊缝脱渣性影响较大的两种敷料,即金红石和钛白粉。它们的含量(主要成分为TiO2)增加时,在熔渣的微观结构中形成呈树枝状或方向性较强的骨架状结构,主干尺寸长、分枝面积大而密的白色相增多,不锈钢焊条的脱渣性能变好。更多还原

【Abstract】 With uniform design method,tooking the coating ingredients as independent variables and slag detachability as the target function in the formula and usability test,the effects of coating components on the detachability of stainless steel electrode were studied.Based on the calculates and analysis result,the two bigger effective supplementary materials-rutile and the powder of TiO₂ were studied.When they（mainly TiO₂） increase,the microscopic structure in the slag will form branchlike or the stronger directive frame-like structure.The white fir-tree crystal phase gets more and the detachability turns better,as the branches get longer,the branching area bigger and denser.更多还原
