More Information
Summary:Methods for controlling blowing, controlling the slag formation and predicting slopping in the blowing of molten pig iron in LD converter are carried out by measuring acceleration of the horizontal movement of a detector, such as a lance provided in the converter, which is caused only by the slag impinging against the lance, by an accelerator, integrating the measured values to obtain integrated average values at every several seconds, and programming the integrated average values in a computer.
