摘要: A process for casting ingot molds wherein a smooth, rigidized insulative board is used to form the as cast bottom surface of the ingot mold to produce a smooth flat surface which does not require machining and to permit slow cooling and solidification so that a uniform macrostructure and microstructure is effected.

摘要: A simple method of producing a rim-stabilized steel ingot without requiring the use of special equipment wherein a rimming-type steel is teemed into an ingot mold and thereafter allowed to rim for a suitable period of time, and then adding a particulate mixture of aluminum and an exothermic material to the top of the molten metal so that the exothermic mixture will ignite, melting and superheating the aluminum content which is driven into the molten steel at the ingot core.

摘要: A pressurized tundish for controlling a continous flow of molten metal characterized by having a pair of principal compartments, one being essentially unpressurized and receiving molten metal introduced thereto, and the other being adapted for maintaining a controlled gaseous pressure over the surface of the fluid metal therein, whereby, by controlling the pressure within the pressurized chamber, metal exiting from the tundish is made to flow continually and at a controlled rate.
