Today 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continuously withdrawn from the mould through roller, friction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.
