Application of the advantages and disadvantages of the composite cemented carbide roller in the wire rod mill

Cemented carbide roller rings with high hardness, good abrasion resistance on the wire rod mill reflects the following advantages:

(1) improve the quality of steel products, the steel surface quality and tolerances been completely resolved, negative deviation control is very precise;
(2) reduce to change the tank, the roll changing times and downtime, and increase mill capacity utilization and production, the mill at the same time create greater economic benefits;
(3) to reduce the rejection rate, reduce the labor intensity of production workshop;
(4) reduce production costs, increasing efficiency of enterprises;
(5) in favor of endless rolling technology applications.

The disadvantages are: cemented carbide roller rings high hardness, brittleness, high sensitivity to crack, resulting in the maintenance more difficult, in the use of cooling water requirements, and can not withstand thermal shock, otherwise easily lead to destructive accidents. 

Composite Cemented Carbide Roll Installation

Cemented carbide roller is a high-tech means to create the high temperature thermal cracking of high-performance roller, the correct roll pass processing, maintenance, and can greatly improve the rational use of rolling destroy rolling tonnage, improve rolling stability, the mill production work rate and negative deviation rate. If used improperly, it will produce rolled destroy chunk off the meat, severe depth of the crack of the cemented carbide roller until the roll cracking scrapped, resulting in a serious waste (cemented carbide roller price to high NiCr roll the times). To be reasonable, scientifically cemented carbide roller, reducing the roll consumption, lower production costs, reduce labor intensity of the operator, to offer you the following cemented carbide roller note, for reference.
