Definitions

  • the cooling rate necessary to provide the self-sizing characteristics is related to the thickness of the high carbon ferromanganese slabs and this relationship is shown graphically in FIGURE 3 of the drawing.
  • a cooling rate in the shaded portion of the graph is selected corresponding to the thickness of the ferromanganese slab.
  • a slower cooling rate is required.
  • molten high carbon ferromanganese at a temperature of at least 1100 C. is poured from a ladle 1 into tundish 2 and then into molds 3 which are mounted on casting conveyor 5.
  • the molds can be made of cast iron or steel and are suitably about 20 inches x inches x 5 inches.
  • the molds 3 on casting conveyor 5 are moved by a suitable driving mechanism 4 at a rate such that the ferromanganese is solidified and is at a temperature of about 1100 C. by the time it reaches the end of the casting conveyor 5.
  • the solidified slabs 6 of ferromanganese are ejected from molds 3 and deposited on cooling conveyor 7.
  • air cooling To facilitate cooling of the slabs and obtain the cooling rate appropriate to the slabs thickness, air cooling,
  • the sizing of the ferromanganese alloy recovered from the screening device showed the following Table Ib average proportions for 38,000 pounds of alloy.
  • the cooling conveyor was 350 feet in length and transported the ferromanganese at a rate of 18 feet per minute so that the ferromanganese was on the cooling conveyor for about 19.4 minutes. During travel along the cooling conveyor, the ferromanganese was subjected to a cooling treatment so that the temperature of the ferromanganese leaving the cooling conveyor was about 200 C. The cooling rate of the solidified ferromanganese was on the order of 46.4 C. per minute.
