What are the working principles of the spreader for billet [answered]

Billet refers to the blank before finishing rolling in steel mills, and the common ones are slab and rectangular billet. Steel mills, wharves, ports and other places need to use professional tools when carrying steel billets in large quantities! The lifting appliance for billet is mainly composed of seven parts: lifting beam, connecting rod, hoist, synchronizer, tong arm, support plate and Tong tooth. Zhengshen, let's talk about the working principle of the spreader for billet.

The lifting appliance for billet adopts the lever principle, which can realize the clamping of billet without the assistance of external force, and the clamping is reliable, the action is flexible, and the lifting is safe and stable. The main part is made of high-quality low-carbon alloy steel with high strength and wear resistance, which has flexible action and long service life. The structure square billet tongs are divided into fixed and adjustable (height h is stepless and adjustable) to adapt to the lifting of square billets of different specifications and layers, and can be designed according to the lifting requirements of customers.

For the spreader used for billet, its core is the opening and closing mechanism. The spreader for billet adopts automatic opening and closing mechanism, which is the mechanism to realize the automatic opening and closing of billet fixture. Its action does not need any external power source, and the automatic opening and closing of the fixture can be realized by the gravity of the fixture itself. Because of the importance of the hoisting mechanism, it is necessary to apply lubricating oil (or engine oil) to the moving parts regularly (2-3 days) in daily use, and then move up and down several times until the lubrication is complete. To ensure the stability and safety of lifting steel with spreaders.
