Trong môi trường nóng chảy cảm ứng, operators face the dual threats of extreme temperatures (high infrared/ultraviolet radiation) Và molten metal splashes. Standard industrial safety gear is insufficient. specialized equipment is required to prevent severe thermal burns and long-term ocular damage.
1. Head and Face Protection (bức xạ & giật gân)
Induction furnaces emit intense light containing high levels of Infrared (IR) Và Ultraviolet (UV) radiation. Prolonged exposure can lead to “glassblower’s cataracts.”
- Gold-Coated Face Shields: Operators must use polycarbonate shields with a vacuum-deposited gold coating. The gold layer reflects over 90% of radiant heat (IR), keeping the face cool and protecting the eyes.
- Sự an toàn Glasses (Cobalt Blue / IR Bộ lọc): Underneath the face shield, impact-resistant safety glasses should be worn. If the operator needs to inspect the melt, Cobalt Blue lenses are recommended to filter out the glare and allow clear visibility of the metal surface and slag.
- High-Heat Hard Hats: Use helmets made of fiberglass or high-performance composites capable of withstanding high radiant heat without softening or warping.
2. Body Protection (Radiant Heat & giật gân)
The core principle for body protection in induction melting is reflecting radiant heat Và preventing molten metal adhesion.
- Aluminized Clothing: For high-intensity radiant heat, operators should wear aluminized coats, aprons, or full suits. The aluminized surface reflects the heat away from the body.
- Flame-Resistant (FR) Base Layers: It is strictly prohibited to wear synthetic fabrics like polyester or nylon. In the event of a splash, synthetics will melt and fuse to the skin, causing deep, traumatic burns. Sử dụng 100% FR-treated cotton or wool base layers.
- “Shed-Ready” Thiết kế: Specialized foundry clothing should follow the “funnel” principle—no external pockets, cuffs, or folds where molten metal could get trapped. All closures should be quick-release (ví dụ., Velcro or break-away snaps).
3. Hand and Foot Protection (Heavy-Duty Splash)
- Aluminized-Back Gloves: These gloves feature an aluminized back to reflect heat, while the palms are typically made of heavy-duty Kevlar or treated leather for abrasion resistance and grip.
- Foundry Boots: * Must be laceless with quick-release features to ensure they can be kicked off instantly if metal enters the boot.
- Must include Metatarsal Guards to protect the top of the foot from heavy impacts and splashes.
- Spats/Leggings: These cover the gap between the boot and the trousers, ensuring molten metal slides off onto the floor rather than into the boot.
4. Special Considerations for Induction Environments
- Non-Magnetic Tools: Because induction furnaces create powerful electromagnetic fields (Emf), tools like sampling spoons or slag rakes should be không có từ tính (kim loại màu). Ferrous tools can heat up rapidly in the operator’s hand due to induction.
- Pacemaker Warning: The strong magnetic fields can interfere with cardiac pacemakers or ICDs. Employees with these devices must be strictly prohibited from entering the induction furnace area.
- Respiratory Protection: Melting processes often release toxic metal fumes (ví dụ., kẽm, Chỉ huy, or Manganese oxides). High-efficiency respirators (such as P100 filters) should be used if local exhaust ventilation is insufficient.
