Effect of TiO₂ on detachability of stainless steel electrode

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.
