What is the hardness of industrial tungsten carbide rollers?
In the industrial field, the hardness of tungsten carbide coated rollers typically ranges from HV1100 to HV1600. These hardness parameters are far higher than those of ordinary steel rollers (HRC 30–55 ≈ HV 300–550) and significantly higher than chrome-plated surfaces (HV 800–1000).

What is an Industrial Mirror Roller?
A mirror roller is an industrial roller that has undergone high-precision machining and polishing. Its surface has an extremely high degree of smoothness, typically reaching Ra0.01–0.02 μm or higher. Mirror rollers are used for pressing, traction, shaping, polishing, or optical-grade surface replication of materials.

Can Magnets Attract to Industrial Tungsten Carbide Coated Rollers?
A magnet will not attract the tungsten carbide coating itself. However, whether a magnet can attract the entire "tungsten carbide coated roller" depends on whether the roller substrate is magnetic. For example: • If the substrate is carbon steel → magnetic → a magnet can attract it.

What are industrial heated rollers used for?
Almost all industries that require material softening, plasticizing, coating, pressing, stretching, or shaping require heated rollers. In short, wherever a production line uses heat to influence material properties, heated rollers play a crucial role.
Water-Guiding and Oil-Guiding Heating Rollers: Which Heats up Faster?

Water-Guiding and Oil-Guiding Heating Rollers: Which Heats up Faster?
Hot water typically heats up faster in the low-temperature range (≤150℃). • Hot water heating roller → The medium transfers heat to the roller body more quickly → The roller body heats up faster. • Oil-guided heating roller → Heat transfer is slower → The heating rate is naturally slower.
