In stainless steel processing, removing internal stress from sheet metal is critical to ensuring flatness and precision in subsequent manufacturing. A stainless steel (also known as a leveling machine or open flattening machine) plays a vital role in this process. In this article, we¡¯ll explore how a 0.3m stainless steel leveling machine eliminates stress, enhances flatness, and optimizes production quality.

How Does a Stainless Steel Leveling Machine Eliminate Stress?

A stainless steel leveling machine operates on a multi-roller working principle, allowing the sheet to undergo repeated plastic deformation between upper and lower leveling rollers. This process effectively eliminates internal stresses and ensures a flat and even surface.

The machine is structured with upper and lower work rolls, supported by rigid backup rolls on the outer sides, forming a four-high roller system. This configuration increases rigidity and uniform pressure during leveling.

Working Principle of the Cut-to-Length Leveling Process

The upper roller, symmetrically positioned between two lower rollers, applies pressure through a backup roll. A torque shaft, powered by a main reducer, drives both the upper and lower rollers in a synchronous rotational movement, applying torque to the stainless steel sheet.

As the sheet passes through the rollers:

• The upper roller presses downward

• The lower roller rotates to pull the sheet forward

• The sheet undergoes multiple continuous bends to create permanent plastic deformation

This process extends the shorter material fibers by stretching them under controlled bending at small radii of curvature, aligning them with the longer fibers, and ultimately achieving flatness and internal stress relief.

Advanced Leveling Technology for Precise Results

High-precision leveling machines can selectively elongate sections of a metal sheet to obtain uniform fiber lengths. As the sheet moves from the machine inlet to the outlet:

• The degree of bending gradually reduces

• The transition eliminates deformation caused by abrupt bending at the entry

• The sheet exits perfectly leveled and stress-free
