Cast Iron: Properties, Processing and Applications - Matmatch
Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.
Co-Current Vs. Counter Current: Kiln Air Flow
Thermal Processing. Co-current air flow, which is also referred to as parallel flow, is when the products of combustion flow in the same direction as the material. This immediately puts the coldest material in contact with the hottest gas in the kiln, resulting in a rapid initial temperature change. Co-current kilns work best with materials ...
