Cleaning & descaling

Continuous shot-blasting installations for straightened wire rod descaling

The DS series of descaler from Carlo Banfi are designed to meet the production requirements of metallurgical products from straightened wire rod with SA3 finishing, and an A or B initial surface quality. The DS machines can process the range of cross-sections (round, square, hexagonal or flat) at speeds over 180m per minute. The inlet and outlet guides are correlated to the required shape, but guide replacement is said to be quick and easy. The output of the blasting operation directs the abrasive jets onto the work piece without leaks. The materials used for the output liners are highly wear-resistant with differentiated com- position according to the impact or friction strength of the abrasive in use. Other products in the Carlo Banfi range include: Foundry-forging shot-blasting systems to • descale both iron and non-iron metals Pickling of wire rods and bars in materials of • various sizes and sections, either continuous or in coils Shot peening equipment specifically • designed for helical, cylindrical, parabolic and diaphragm springs

New wire cleaning series Ultrasonic cleaning is recognised as a highly efficient cleaning method for the surface treatment of wire- or band-shaped endless profiles, yielding excellent surface quality even at high processing speeds. GEO-Reinigungstechnik is among specialists in the use of ultrasonic cleaning technology. Whether the requirement is for a comprehensive turnkey system, an upgrade, or an addition to an existing process, GEO offers application specific solutions. GEO’s new wire cleaning series (WCS) comprises four basic systems, designed to clean, rinse, and dry continuous lengths of single-line wire- or band-shaped endless profiles from a couple of micrometres up to 30mm diameter. WCS lines can be installed in-line with a wiredrawing machine, in front of annealing operations, or can be used as a stand-alone unit where the wire is wound on spools. The purifying plant consists of several modules placed in a row according to the procedure.

The core of GEO’s wire cleaning system is a high performance ultrasonic tube reactor, optimised for continuous industrial profile cleaning. Inside the tube, the cleaning fluid is exposed to a high-intensive ultrasonic field to create cavitation.The concentration across the entire tube cross-section and the distinctive focus zone inside the tube causes an intensive sonication that effectively removes soap, grease, oil, emulsions or particulate contaminants inline. The compact design includes cleaning and rinsing circuits with heated and insulated liquid tanks, bag filter systems and a touch screen-based user interface and fault display.
