What material is used to hold molten iron in a furnace?
Cast iron is produced in a 'cupola furnace,' historically built from brick although modern ones tend to be steel with a refractory lining. Charges of iron ore and charcoal (or coke) are fed into the top of the stack and molten metal accumulates in a well a the the bottom where it can be 'tapped' by punching through a clay plug.

12.4 Ferroalloy Production
12.4.1 General. Ferroalloy is an alloy of iron with some element other than carbon. Ferroalloy is used to physically introduce or "carry" that element into molten metal, usually during steel manufacture. In practice, the term ferroalloy is used to include any alloys that introduce reactive elements or alloy systems, such as nickel and cobalt ...
Manganese | Uses, Facts, & Compounds | Britannica
Compounds. Of the wide variety of compounds formed by manganese, the most stable occur in oxidation states +2, +6, and +7. These are exemplified, respectively, by the manganous salts (with manganese as the Mn 2+ ion), the manganates (MnO 4 2−), and the permanganates (MnO 4 −).As in the case of titanium, vanadium, and chromium, the …

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal
Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.
Separation of Mn and Fe from a Manganiferous Iron Ore Using

Manganese Steel FAQ | Clifton Steel
The natural presence of manganese in the iron ore used by the Spartans is believed to be why their steel weapons were superior to those of their enemies – USGS. Manganese steel is a steel alloy containing 11-14% manganese. It's often referred to as Hadfield steel, or Hadfield grade, as Sir Robert Hadfield discovered it in.

Effect of Moisture, Hydrogen, and Water–Gas Shift Reaction
The extent of these reactions is given by the oxygen level of the ore, which typically is close to that of MnO 2 (high oxygen ores) or Mn 2 O 3 (semi-oxygen ores). The reduction of higher manganese oxides by CO(g) is highly exothermic (as seen in Reaction 1.1-1.3) and will thus heat the charge material, implying that a high oxygen level will …
MANGANIFEROUS IRON ORES.
high-grade ore has been mined for the production of iron-manganese alloys. Much of the manganiferous iron ore of the Cuyuna range has likewise been used in the manufacture of iron-manganese alloys, the ore usually being mixed with foreign high-grade manganese ore. The Cuyuna ore is generally either too high in phosphorus or too
Production of Ferroalloys
Since a single manganese ore of this ratio is seldom available, blending of ores from different sources is common practice to reach the desired manganese-to-iron ratio and to control the level of deleterious elements, particularly phosphorous. The use of sinter as a source of manganese is becoming increasingly popular.
