This caused a thin layer of chromium to coat the walls of the vessel above the reduction zone. This thin layer of metal is commonly referred to as an armour plate. It is the object of this invention to produce chromium-nickel master alloys having a nitrogen content of less than 0.005%, preferably as low as 0.001% to 0.003%, by weight.

The crucible is surrounded by sand which prevents loss of heat by radiation. The mixture is ignited by a piece of Mg ribbon. During this process a large amount of heat is liberated, in which Cr2O3 is reduced to chromium. The molten chromium is collected in the crucible and aluminium oxide is removed as slag. Cr 2 O 3 + 2Al →2Cr + Al 2 O 3 ...

Rotor impact mill RPM. The feed material is loaded into the top center of the machine. When it impacts the rotor, the material is accelerated towards the outside by means of centrifugal forces; there, the horseshoe-shaped hammers engage it and throw it against the anvil ring, In the milling gap, it is crushed as a result of the impact and shearing forces.

The "hammers" strike the whole grain in mid-air with such an impact that the grain is immediately shattered into flour. There is no friction from heat-creating stones or rollers. Temperature is the key factor here. An impact mill maintains a low temperature of about 15 C in the cooler months and up to about 30 C in the summer.
