  • Patent number: 4098321
    Abstract: A pouring pot for pouring molten metal into a casting mold of a continuous casting apparatus comprises upper and lower pot sections with the upper pot section having a volume sufficiently larger than the effective volume of the lower pot section so as to maintain the molten metal pressure depth and therefore the pressure head substantially constant despite fluctuations in the total amount of molten metal in the pouring pot to thereby effect discharging of the molten metal at a substantially constant flow rate. The upper pot section has a volume at least 20% greater and preferably 20%-40% greater than the effective volume of the lower pot section. The overall volume of the pouring pot is similar to that of conventional low volume pots now in use so that conventional supporting equipment can be used to support the pouring pot.
