Metal Processing Equipment Manufacturer for Peeling, Grinding, Cutting and Pickling Lines

The two-roll straightening machine is designed for straightening round bars, tubes and shaft-type workpieces after rolling, drawing, heat treatment or peeling. It corrects bending and improves straightness while supporting stable downstream machining quality. The machine uses two specially profiled straightening rolls to apply controlled pressure and rotation to the workpiece. It is suitable for carbon steel, alloy steel, bearing steel, stainless steel, spring steel, titanium alloy and other metal bars or tubes. The equipment is available in light-duty and heavy-duty configurations according to material diameter, strength and production speed. It is widely used in bright bar production lines, tube processing lines and precision metal material finishing. Advantages include compact structure, reliable straightening performance, easy operation, convenient adjustment and strong adaptability to different bar and tube specifications.

The press straightening machine is used for correcting local bending and deformation of bars, shafts, tubes, profiles and forged parts. It is especially suitable for point-by-point correction after heat treatment, machining, forging or transportation. The equipment applies controlled hydraulic pressure to selected bending positions while the operator or measuring system checks straightness and adjusts the correction amount. It can handle high-strength steel parts and larger workpieces that are not suitable for continuous roll straightening. Typical applications include shaft straightening, round bar correction, tube straightening, mold component repair, forged part finishing and heavy mechanical part rework. The machine features strong pressing force, stable hydraulic performance, easy operation and flexible tooling options. It helps reduce scrap rate and improves dimensional accuracy before final machining or inspection.

The seven roll straightener is used to straighten the bending of bar or tube created in the rolling process. It has obvious effect in solving bar head or tail bending, eliminating slight ellipticity and removing oxide scale. The material of bar or tube includes Carbon tool steel, carbon structural steel, alloy tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, titanium chromium nickel alloy etc..

The automatic acid and alkaline cleaning line for metal wire is designed for continuous surface cleaning, pickling, rinsing and neutralization of steel wire and other metal wire materials. The line can include tunnel-type automatic pickling, acid mist purification, wastewater purification and reuse, fully enclosed alkaline liquid delivery pipelines, acid mist treatment towers and corrosion-resistant tanks. The system removes rust, oxide scale and surface contamination before wire drawing, coating, plating or further processing. It improves surface activation, process stability and environmental performance. It can be customized for different wire diameters, line speeds, cleaning processes, tank layouts and automation levels.

The pipeline pickling line is designed for automatic acid pickling, rinsing, neutralization and surface cleaning of pipes and tubular workpieces. It can be configured with an acid mist purification system and wastewater purification and reuse system. The production line supports pipeline pickling, automatic pickling, acid mist collection, wastewater treatment, corrosion-resistant tanks, circulation systems, transfer devices and centralized control. It is suitable for removing oxide scale, rust and surface contamination before coating, galvanizing, passivation or further processing. The line improves surface cleanliness, production efficiency and environmental control. The system can be customized according to pipe size, output capacity, process flow, plant layout and environmental protection requirements.
