Merits of Tungsten Carbide corrugating roll
Δ Strong combination between coating and matrix ensuring long service life of coating without any peeling.
Δ With higher hardness of coating, abrasion reesistance will increase manyfold and service life will be prolonged linearly.
Δ Thickness of coating could be even and accurately controlled,ensruing precision rolls.
Δ Sruface roughness of coating will reach to Ra0.4-0.6after special fine polishing,pretty suitable for high-speed corrugated cardboard making machine .
Δ Matching with flute designs of UV and UVV type, increase efficently hardness of cardboard and deduct wastage of paste and medium paper.
Δ The oretically,flutes in service will be never worn and take up ratio will be never changed.
Δ By using tungsten carbide corrugating rolls,cardboard will be maintained at certain thiceness and printed always flat for stable quality of cardboard and carton.
Δ Used coating could be removed by special process and the rolls could te refurbished for reuse.
Δ Improvement in service life deducts frequencies of changing,saving expenditure of manpower and material resources.
Comparison on Service life of corrugating rolls
Δ Service life of hard chrome corrugating rolls is usually during 6milion to 8 milion;But fo tungsten carbide corrugating rolls,its service life could be reach to at least more than 30 milion,which dedects frequencies of changing and saves expenditure of manpwer and material resources.
