METHOD FOR PRODUCING CEMENT

摘要

METHOD OF PRODUCING CEMENT Tricalcium silicate materials useful in the production of portland and other hydraulic cements are prepared by adding a mixture of silica and lime containing materials to an electric furnace and melting the mateials. The materials may be added in lump form and need not be pulverized. The voltage between the electrodes and the conductivity of the melt are controlled so that a predetermined separation will be maintained between the lower end of the carbon electrodes and the melt.
