Valgro Wet Brushing Hot Tempered Strip Machine

Product Description

Improve the surface quality of hardened and tempered steel strips with the Valgro Wet Brushing Hard & Tempered Strip Machine — a dedicated wet-brushing solution designed for strip finishing where tight flatness and minimal material removal are required.

Overview

This wet-brushing machine uses rotating abrasive brushes under coolant to uniformly remove a thin layer (approximately 1-2 µm) from hardened or tempered steel strips. It’s designed to reduce surface roughness (from approx Ra 1.15 µm incoming down to Ra 0.12 µm) and remove loose scale, micro-irregularities or surface contamination, while preserving flatness (no camber or deformation). It includes a sealed brushing chamber with inspection windows for process monitoring.

Key Features

• Designed for wet brushing of hardened/tempered strips, utilising coolant to manage heat and clean sweeping.

• Removes approx 1-2 µm of material to deliver a refined surface with low roughness (target Ra ≈ 0.12 µm).

• Vibration-free and stable operation with guarantee of no strip deformation or camber.

• Sealed machine housing with viewing windows for operator visibility.

• Low noise operation (< 80 dB) and power-efficient performance.

• Robust, heavy-duty construction built for continuous industrial strip processing.

Benefits

• Consistently delivers high-quality strip surfaces with improved flatness and finish quality.

• Helps downstream processes (coating, cladding, bonding) by providing a better base surface condition.

• Wet process improves tool life and process cleanliness compared to dry brushing in certain contexts.

• Reduces operational defects such as strip camber or handling issues due to improved flatness.

• Suitable for high-volume industrial lines where reliability and repeatable results are essential.

Typical Applications

• Surface preparation of hardened or tempered steel strips used in cladding, coating, bonding or roll-processing.

• Strip finishing where removal of light scale, annealing colours or micro defects is required before further processing.

• Heavy industrial strip lines where maintaining flatness and surface uniformity is critical (automotive, heavy fabrication, bearing strips, high-precision components).

• Facilities preferring wet brushing due to cooling, material condition or process-integration advantages.
