The furnace roll is delivered with a high roughness surface, in order to maintain good adhesion to the strip and to prevent skid, which can produce nodules and scratches. The purpose of high temperature coating: a) improve the wear resistance of the furnace roller at high temperature, improve the hardness, Cr25Ni20, Cr28Ni48, with the hardness drop, surface roughness decreases, cause the strip slip, the tension is not isi blong stanemap; b) namba tu as tingting em long sakim ol nodul, nodulation i kamap bikos long strip pes; o bikos ol i mekim strip stiel i go daun long bikpela tempereja.

Spreim rot: a), teknoloji bilong spreim ol supasonik, wok bilong wok<500℃, using materials: Co base alloy, good low temperature wear resistance, oxidation resistance and good corrosion resistance; working temperature <900℃, using material: NiCr alloy, good thermal corrosion resistance and wear resistance under medium and high temperature conditions, corrosion resistance, corrosion resistance, micro vibration and grinding wear, good corrosion resistance, good wear and oxidation resistance at medium and high temperature.

B), Explosion spraying technology, working temperature>900 digri , yusim ol samting: aloi + oksait (metal seramik), bikpela tempereja wear resistens, bikpela tempereja oksaitesen resistens, bikpela tempereja i pas wantaim (nodulasen resistens).

Disain tingting bilong ol samting i no inap long kisim bikpela tempereja em: metal (metal aloi) + metal seramiks (i no metal). Nambawan bikpela hat tempereja hat em i no metalik seramiks seramiks seramiks . Bilong mekim sure olsem seramik i no ken pundaun, ain fez (bonding fes) na metal seramiks i mas kamap strong) i mas kam insait long en. resistens na strong, olsem LCO-17,56. 1001000 digri wara bilong mekim wara i kol.

The coating principle of the high temperature furnace roller of the furnace supplier is basically the same, that is, the heating section, partial heat section and cooling section adopt high temperature resistance coating, and the 950 or 1050℃in the heating section and partial 050℃heat resistance coating. Coated roller roughness is between 1 and 10 μm Ra. There are several coating suppliers and brands long wol, olsem:
