Results indicate that surface inclusions can be reduced and physical product quality of steel improved by taking a few proper measures including the use of high quality mould powder and refactory mate- rial and an increase in amount of final deoxidizing Al.

Against the characteristics of surface inclusions of medium plate,the resources of inclusions,the influence of the performances and shape of casting powder to inclusions were analyzed.

This paper studies the problem of surface inclusions and cracks of continuous casting slab at Maanshan Steel and puts forward corresponding measures to solve the problem.

Having fixture surface accessibility analysis as the core, the optimum selection of fixturing surfaces and points on workpiece is fullfilled.

Methods and causes of surface slag on cast-rolling strip

Influence of shape and size of inclusion on crack initiation was studied,and the relationship of inclusion area and the initiation stress of the first crack in the inclusion under tensile load was discussed.
