Abstract
Control method for preventing a breakout or/and a crack of the slab of continuous casting equipment. Heat flux waveforms or heat flux values commensurate to extracted heat values at various positions of a mold are measured by means of thin plate type surface heat flux meters (14, 14x, 14y, 14z) provided at various positions on side shell plate (11, 11c) of the mold (10). When an abnormality or a deviation from a target value is detected, pouring rate is changed, scope of supply, brands and the like of mold powder are controlled, or taper value of short sides of the mold is controlled, so that a breakout or/and a crack of the slab is prevented.
Claims11
A method of controlling continuous casting equipment, comprising the steps of:
- providing a heat flux meter on an outer surface of a side shell plate of a mold;
- measuring a local heat flux waveform commensurate to a local extracted heat value of said mold with said heat fux meter;
- detecting an abnormality of said local heat flux waveform;
- and
- adjusting the operation of said equipment responsive to said detection of an abnormality.
