Title:
MANUFACTURE OF STEEL IN CONVERTER
Document Type and Number:
Japanese Patent JPS6112811
Kind Code:
A
Abstract:
PURPOSE: To reduce considerably blowing time by accurately estimating the amount of P in molten steel without tilting a converter.
CONSTITUTION: Molten steel is sampled with a sublance. The amount of C in the molten steel is estimated from the solifying temp. of the sample, and the temp. of the molten steel and the amount of O in the molten steel are measured. The composition of slag is estimated from the measured values and the amount of Si in molten iron, and the amount of P in the molten steel is estimated from the estimated composition and the temp. of the molten steel. Whether the molten steel is fit for discharge or not is judged from the estimated value.
