Introduction
The metallurgical hoist hook consists of hook body, hook shank, nut, thrust bearing, anti-fall pawl and heat insulation baffle, specially designed for high-temperature heavy-load environments of metallurgical electric hoists. The hook body is integrally forged from high-quality alloy steel (such as 20CrMnTi, 42CrMo), special heat treatment such as normalizing + tempering + surface quenching, the hook body has high strength, high toughness, impact resistance and high temperature resistance; the hook shank is connected to the metallurgical electric hoist hoisting mechanism through a nut and thrust bearing, the hook can rotate freely, facilitating load direction adjustment; the anti-fall pawl adopts spring-return type, preventing accidental unhooking of slings; some models are equipped with a heat insulation baffle to block radiant heat from high-temperature heavy objects, protecting the electric hoist hoisting mechanism. During operation, the hook is connected to the metallurgical electric hoist hoisting wire rope or chain through the hook shank, and the hook body suspends high-temperature heavy objects such as steel ladles, iron ladles, steel ingots and castings, bearing heavy load and high-temperature radiation; the metallurgical hoist hook safety factor ≥5 times, higher than ordinary electric hoist hooks (≥4 times), ensuring lifting safety in metallurgical heavy-load high-temperature environments. The metallurgical hoist hook can be matched with 0.5t~32t various tonnage metallurgical electric hoists, widely used in charging in metallurgical workshops, iron ladle lifting in foundries, workpiece lifting in heat treatment workshops, steel billet lifting in forging workshops, serving as the core lifting device for high-temperature heavy object lifting of metallurgical electric hoists.

Our Advantage
Integrally forged from high-quality alloy steel (20CrMnTi/42CrMo), special heat treatment such as normalizing + tempering + surface quenching, the hook body has high strength, high toughness, impact resistance and high temperature resistance, can withstand continuous operation in ≤200°C radiant heat environment; safety factor ≥5 times, higher than ordinary electric hoist hooks, each hook undergoes magnetic particle inspection and load test, tested via 1.25× rated load static test, ensuring lifting safety in metallurgical heavy-load high-temperature environments.
Specially designed for metallurgical electric hoists, hook shank size and connection method fully match the metallurgical electric hoist hoisting mechanism, can directly replace ordinary electric hoist hooks, convenient installation without modification; equipped with a heat insulation baffle to block radiant heat from high-temperature heavy objects, protecting the electric hoist hoisting mechanism and wire rope from high temperature; can be matched with 0.5t~32t various tonnage metallurgical electric hoists, strong adaptability.
Equipped with a spring-return anti-fall pawl, after the sling is hung in, the pawl automatically resets to close the hook opening, preventing the sling from accidentally unhooking due to vibration and sway during lifting; equipped with a heat insulation baffle, effectively blocking radiant heat from high-temperature heavy objects such as steel ladles and iron ladles, protecting the hook, wire rope and electric hoist hoisting mechanism; double safety protection, ensuring lifting safety in metallurgical high-temperature environments, far superior to ordinary hooks without anti-fall and heat insulation.
The hook body adopts an integrally forged structure without welding defects, high strength, impact resistance and fatigue resistance; the hook shank thrust bearing adopts high-temperature resistant grease, flexible operation and durable; hook opening and hook bottom fillets are optimized to reduce sling wear; the hook surface is treated by shot blasting + high-temperature resistant painting, corrosion-resistant and oxidation-resistant; normal service life over 8 years, suitable for 24-hour continuous heavy-load operation in metallurgical workshops, low maintenance cost and long comprehensive service life.
The metallurgical hoist hook adopts modular design, wearing parts such as anti-fall pawl, spring and thrust bearing can be replaced separately, convenient maintenance and low cost; the hook body is integrally forged without vulnerable structure, daily only requires regular inspection of hook body wear, cracks and anti-fall pawl status; compared with same tonnage bridge crane metallurgical hooks, it is smaller, lighter and cheaper, high cost-effectiveness when matched with metallurgical electric hoists, serving as an economical choice for small and medium tonnage metallurgical high-temperature lifting.
