Continuous casting is a complex process affected by a number of factors and it is necessary to optimise these factors (e.g. shell lubrication and heat extraction) to minimise product defects and process problems. The mould powder is expected to alleviate these problems. However, the casting conditions have a pronounced effect on factors like slag infiltration and heat transfer and this requires careful selection of mould slag properties to provide optimum casting conditions. The effect of individual, casting variables (e.g., casting speed) on the casting process is discussed in this chapter and the following casting variables are examined and discussed: (i) mould characteristics (e.g., dimensions, taper, coatings) (ii) oscillation characteristics (iii) casting speed (iv) metal flow characteristics (v) metal-level variations (vi) fluctuations (in metal flow, mould level, etc. (vii) the application of electromagnetic devices (viii) steel grade being cast (ix) water flow rate. The effects of these individual factors are discussed and how the mould powder can be used to optimise the casting process.
