HFI Cooler Plates

Hard Faced Insert cooler plates have been developed to meet the demanding operating conditions found in some Clinker Coolers. Subjected to high abrasion and elevated temperatures, Cooler Plates are often found to experience abnormally high wear in the stroke area of the plate resulting in excessive downtime.
 
To reduce the effect of abrasion and elevated temperatures an Insert is fitted to the casting on the area behind the cooling slots. The Insert is plate with a weld overlay, the metallurgy of which has outstanding resistance to abrasion at both ambient and elevated temperatures.
 
The material, most commonly a chromium carbide alloy, is deposited using the submerged arc process ensuring a smooth surface giving minimum resistance to flow of clinker over the face.
 
The composition of the alloy face is made up by the introduction of a carefully controlled blend into the weld pool. This method of production means there is virtually no restriction to the specification of alloy overlay and thus can be tailored to meet individual applications.
