38CrMoAl mill roll - High Performance Component of Building Materials Machinery

Our 38CrMoAl mill roll provide high-performance parts services for a leading building materials manufacturer's steel strip rolling machinery (used for producing core materials for wall and roof panels).

Mechanical coordination accuracy in the production of building materials:

The through-hole end of the mill roll has a C1 chamfer and complete burr removal function, which not only avoids scratching the 45 steel drive shaft of the machine during assembly, but also ensures smooth torque transmission (crucial for consistent rolling of thin specification steel strips in building materials).

Its cordiality is ≤ 0.03mm (outer contour) ↔  Inner hole axis and perpendicularity (end face) ↔  The ± 0.05mm thickness tolerance requirement between the axis and the machine for building material substrates is perfectly aligned, eliminating 90% of the "strip warping" defects that previously required rework.

Tailored durability for heavy machinery operation:

After quenching, tempering, and nitriding, the surface hardness of the rolling mill reaches HRC58 (exceeding the standard HRC55), and is polished with a roughness of 0.8 μ m. In the 12 hour continuous rolling cycle of the machine (processing over 2000 meters of steel strip per day), after 30 days, the rolling mill only wore 0.02mm, which is 40% higher than the previous alloy steel rolling mill.

Design optimization of mechanical maintenance for building materials:

A 10mm wide and 0.5mm deep groove (machined 5mm below the end face arc) is customized to match the machine's quick release buckle system. This reduces the roller replacement time for each maintenance from 45 minutes to 15 minutes, and reduces unplanned downtime for building material production lines by 25%.

Since the integration of the roller, the manufacturer's rolling machinery has maintained 98% of normal operating time, while the qualification rate of building material substrates has increased from 92% to 99%, directly increasing the monthly production of its wall panel materials by 18%.
