This process is vastly used in respect of any other rolling process. In this process, the metal is heated above the recrystallization temperature.In the hot working process, the metal is changing its grain structure because of the heat, now there were a new set of strain-free grains in the metal and this process needs less amount of force which correspondingly reduces the quality of the ...

Failure mode of coal mill roller was comprehensively analyzed and current situation of mill roller repair was elaborated. Process characteristic and application effect of metal cerement and high chromium cast iron building-up materials were expounded in the article. Owing to excellent wear resistant and low cost, high chromium cast iron building-up materials have been applied widely.


frequent recorrugation. Cost for servicing rolls will typically be on the order of $0.02 - $0.03 per ton. If only 70% of the roll surface is actually worn, this cost per ton can easily go to $0.04 - $0.05 per ton. Multiplied over the life of the roll these added costs could be anywhere from $2,500 to more than $10,000 for 1200-52 and 1200-72 rolls.
