AbstractToday steel is one of the most common material used in almost everywhere from seat belt mechanism to petroleum pipeline. Steel production requires many steps including the steel making and continuous casting plants. Starting with first drafts in 1856 continuous casting machines has evolved today’s modern machines. One of the most important part of continuous casting machines effecting the quality, productivity and yield is the openended copper mould. With time there is needed more control over casters due to the increasing quality demand and machine yield. When liquid steel is poured through the mould first solidification occurs around slab strand. When the strand of steel is continuously withdrawn from the mould through roller, friction happens between strand shell and mould. Mould friction should be kept in optimum range. Beyond this range there can be breakout or produced slab having bad surface quality. Variety of continuous casting parameters effect mould friction such as casting speed, steel grade, mould level, mould powder viscosity, mould oscillation parameters, etc. In this research there can be found how different slab caster parameters effects the mould friction.
