AB Presented paper is focused on research of low carbon steel behaviour during continuous casting process. Research was conducted to investigate optimization opportunity of current casting process and possibility of increase in casting speed. Research was focused mainly on primary cooling area which is represented by mould. Mould insert was drilled, and thermocouples were installed in centreline of each side. Among others also temperatures and flow of cooling water, mould insert temperature and surface temperature of billet on the exit from the mould were measured. From conducted research it can be concluded that all following values exhibit strong linear positive or negative progress with increase in casting speed. Heat flux density increases and specific removed heat decreases with adjusted coefficients of determination 0.92 and 0.97. Surface billet temperature after primary cooling increases with adjusted coefficients of determination 0.94. Increase in casting speed also leads to equalization of measured temperatures of mould wall.
