Parts for Disc-Type Wire Shot Blasting Machines

Product Overview

In some countries and regions, limited wire storage conditions can lead to thicker and harder rust and oxide scale than those typically found in temperate climates. This can easily cause three common problems: groove damage on guide rollers, accelerated wear of wire guide dies, and blockage of blast wheel discs. High humidity may also cause moisture accumulation in the pneumatic tension control system, resulting in unstable wire tension, wire tangling, and knotting, which can disrupt continuous production.

Direct Shipping from the Nearest Warehouse: Blast wheel discs, wire guide rollers, straightening rollers, wire guide dies, pay-off and take-up reels, tension control rollers, and pinch rollers are kept in stock at our domestic and overseas warehouses. Standard specifications can be shipped directly from the nearest warehouse and delivered within 5–7 days. Guide rollers and wire guide dies can be quickly matched and supplied according to the required wire diameter.

Material Selection & Wear Resistance: Blast wheel discs are made of high-chromium cast iron or alloy steel and dynamically balanced before leaving the factory to minimize vibration during high-speed operation. Wire guide rollers are made of Cr12/Cr15 tool steel with surface hardness of HRC60–62 after quenching, providing excellent groove wear resistance and reducing the risk of wire surface damage. Wire guide dies are made from sintered tungsten carbide or ceramic, with mirror-polished bores and ovality of less than 0.02 mm, ensuring smooth wire passage. Straightening rollers are made of bearing steel with hard-chrome-plated surfaces, offering high wear resistance and a low coefficient of friction. Pinch rollers are coated with polyurethane rated at Shore A 80–95, providing reliable driving force while preventing damage to the wire surface.

Key Tips for Energy Saving and Extended Service Life

• Check the guide roller groove wear depth before each shift. If groove wear exceeds 1 mm, replacement or regrinding is recommended. Excessive groove wear can cause wire oscillation and uneven cleaning, and in severe cases may result in machine jamming.
• Clean the blast wheel disc discharge holes before each shift. Oxide scale debris can easily absorb moisture and adhere inside the holes, causing blockage and disrupting dynamic balance, which may lead to an abnormal increase in blast wheel motor current.
• Inspect the inner bore of the wire guide die every week. If a plug gauge indicates that the ovality exceeds 0.1 mm, replace the die promptly to prevent periodic scratches on the wire surface and protect the quality of subsequent wire drawing.
• • Drain water from the pneumatic FRL unit of the tension control system every day, as moisture accumulates quickly in high-humidity environments. Check the magnetic powder brake every month for moisture absorption or powder agglomeration.
• Check the parallelism and locking condition of the straightening roller assembly every month. A loose individual roller can result in inadequate wire straightening, causing the wire to vibrate when entering the blasting chamber and potentially damaging the guide rollers and wire guide dies.
