Abstract
A process for the production of portland and other hydraulic cement products is provided. The process is characterized by an electric furnace into which the reactant materials are fed. The process is further characterized by avoiding the necessity for pulverizing and intergrinding the feed materials. Another characteristic is that all feed materials become molten and remain molten until after removal from the furnace.
Claims15
A process for producing portland cement or other hydraulic cements, said process comprising:
- maintaining in an electric furnace a melt which has the chemical constituency of the desired hydraulic cement;
- introducing a molten material into the melt;
- introducing a solid material into the melt with the solid material being in a nonpulverulent condition;
- mixing the solid and molten materials within the melt by currents generated within the melt by the furnace;
- allowing the molten material to chemically combine with the solid material within the melt such as to maintain the chemical constituency of the melt at that for the desired hydraulic cement;
- withdrawing the melt from the furnace;
- and cooling the withdrawn melt to a solid that has the properties and chemistry of the desired cement.
A process for producing hydraulic cements including portland cement, said process comprising:
- maintaining a melt within an electric furnace, with the melt having the chemical constituency of the desired hydraulic cement;
- heating the melt within the electric furnace and contemporaneously mixing the melt with thermal currents generated within the melt by the electric furnace;
- feeding appropriate materials by gravity into the melt at the surface of the melt and in proportions suitable for providing the melt with the chemical constituency of the desired hydraulic cement;
- allowing the feed materials to chemically combine within the melt;
- withdrawing the melt from the electric furnace;
- and cooling the withdrawn melt to solidify it into a solid substance that has the chemical constituency and properties of the desired hydraulic cement.
A process for producing portland cement or other hydraulic cements, said process comprising:
- introducing raw materials containing compounds suitable for the production of the desired cement into a melt that is contained within an electric furnace and is hot enough to cause the compounds to chemically combine with each other and the melt such that the melt acquires the chemical constituency of the desired cement, at least one of the materials being a solid in a nonpulverulent condition.
