KmTBCr15Mo is a type of high chromium white cast iron, which has been studied deeply and is widely used. It is normally air quenched and tempered and has high hardness, strength, and toughness, with excellent resistance to corrosion and impact abrasion.
High chromium Casting Material is a kind of abrasion resistant material with good performance and special attention. It has much higher wear resistance than alloy steel, and much higher toughness and strength than ordinary white cast iron. At the same time, it also has good resistance to high temperature and wear resistance.
The finish grinding process for cement materials uses ball mills with differently sized grinding balls. Because the grinding takes place through the impact and friction of the balls, balls with a high wear resistance are desirable and the materials of choice are the high-chromium white cast irons.

Especially as the third generation of anti-wear Alloy High Chromium White cast iron developed successfully, so that more than 4.5 m of large-scale cement mill ball consumption to 30 ~ 50 G / T, medium and small-scale cement mill ball consumption also reduced to only 100 G / T or so The new material revolution has greatly improved ...
10%High-chromium white cast iron (HCWCI) is one of the most widely used engineering materials in the mining and cement industries. However, in some components, such as the pulverizer plates of ash mills, the poor machinability of HCWCI creates difficulties. The bimetal casting technique is a suitable method for improving the machinability …
Hexavalent chromium shows up in predominantly three forms: 1) Trivalent Chromium, which occurs naturally as chrome ore and is also an essential nutrient for proper metabolism; 2) Metallic or Elemental Chromium, typically found in aerospace alloys; and 3) Hexavalent Chromium, typically from industrial processes like welding and thermal spray.
The detailed deformation mechanism and its microstructural modifications of white cast iron grinding balls used in comminution have been investigated using transmission electron microscopy (TEM) and XRD. De-shaping is the primary mode of ball consumption, and fracture of balls is a relatively uncommon failure mode. Deshaping is the manifestation of abrasive wear …

Few works have studied the effect of this key parameter on microstructural and mechanical characteristics of high-Cr WCIs. Wieczerzak et al. stated that increasing Cr:C results in different types of Cr carbides, namely Cr 23 C 6, C 7 C 3 and Cr 3 C 2.High-Cr WCIs generally contain other alloying elements such as Mn, Ni, Mo, Cu, etc. rather than only Cr.
