A METHOD FOR THE PREPARATION OF MELTED CLINKER FOR THE PRODUCTION OF WHITE AND PORTLAND CEMENT

摘要

The invention relates to the industry of construction materials, particularly to the method for preparing the melted clinker for the production of white and Portland cement. A method for the preparation of melted clinker for the production of white and Portland cement involves enrichment of flaming melted slag with lime of 65% of weight of the total amount of melted slag, meeting to the end chemical composition of clinker within blast- or open-hearth furnace. Enrichment of flaming melted slag with lime of 65% of weight of the total amount of melted slag is carried out due to the introduction of the charge enriched with lime to a required amount into the furnace at the stage of agglomeration of iron ore concentrate and manufacturing pellets. The invention provides obtaining the melted clinker of while and Portland cement at lower power inputs and fuel consumption.
