Présentation du produit

Overhead slab handling crane equipment, also called a billet crane. It is a heavy-duty handling equipment, specially designed for continuous casting and rolling production lines in the iron and steel industry, which is mainly used for transferring, stacking, loading, and unloading of high-temperature and normal-temperature slabs. The equipment can adapt to high temperature working conditions above 650℃ and meet the lifting requirements of slabs or blooms with a thickness of ≥150mm. It is widely used in key production areas such as continuous casting billet span, billet storage, heating furnace, and finished product storage.

Overhead Clamp Crane for Ingot, Billet & Slab Handling

According to the structural form, slab handling cranes can be divided into three categories: rigid, flexible, and slewing, and the rated load of the hoisting mechanism includes the weight of slabs, the weight of clamps, and the weight of guide cylinders.

Components of Slab Handling Crane

The overhead slab handling crane is mainly composed of a load-bearing structure, a trolley running mechanism, a hoisting mechanism, a spreader system, an intelligent electrical control system, an auxiliary system, and so on. Please see the following introduction:

Carrying structure: It includes a box-type main beam structure, end beam and supporting frame, and traveling cart device.
Trolley traveling mechanism: including driving motor, reducer, wheel set.
Trolley running mechanism: including rail and anchoring device.
Lifting mechanism: including main lifting system (reel, wire rope, pulley set).
Specialized spreader system: including clamping device (mechanical/hydraulic), rotating mechanism (optional), guide cylinder, and balancing device.
Electrical control system: main control cabinet and distribution system, drive control unit, safety monitoring system.
Auxiliary system: cooling protection system, dust removal device, lighting, and warning device.

Working Principle

Ingot, slab, and billet cranes are heavy metallurgical overhead cranes equipped with high-power drive systems and high-temperature-resistant spreaders, which are specially used for the transfer and process connection of high-temperature metal materials. The equipment grabs ingots, slabs, and other materials in high temperatures above 650℃ through special clamps or electromagnetic suction cups for efficient connection between continuous casting, rolling, heat treatment, and other processes. The operation process consists of three key stages: firstly, the high-temperature billets are removed from the billet area of the continuous casting machine, then they are transferred to the heating furnace or rolling mill rollers for re-processing, and finally, the finished products are transported to the slow cooling area or storage area.

Specifications

This slab crane is designed for efficient and secure handling of heavy billets, featuring adjustable clamps that can be configured either perpendicular or parallel to the beam for versatile load positioning. Below are the key parameters for each clamp orientation:

Clamps perpendicular to the beam:

Capacité de levage	La portée	Hauteur de levage	Obligation de travail	Vitesse de levage	Crane Traveling Speed	Vitesse de déplacement du chariot	Track
35 ton	27.5 m	12 m	A7	1.2~12 m/min	4.2~42 m/min	8.5~85 m/min	QU120
50 ton	37 m	12 m		0.95~9.5 m/min	3.8~38 m/min	8~80 m/min
65 ton	35.5 m	12 m		0.78~7.8 m/min	3.8~38 m/min	7.5~75 m/min

Clamps parallel to the beam:

Capacité de levage	La portée	Hauteur de levage	Obligation de travail	Vitesse de levage	Crane Traveling Speed	Vitesse de déplacement du chariot	Track
35 ton	27.5 m	12 m	A7	0.95~9.5 m/min	3.8~38 m/min	8.5~85 m/min	QU120
50 ton	37 m	12 m		0.95~9.5 m/min	3.8~38 m/min	8~80 m/min
65 ton	35.5 m	12 m		0.78~7.8 m/min	3.8~38 m/min	7.5~75 m/min

Caractéristiques

High Temperature Resistant Design: Adopting a heat-insulating coating and a water-cooling system, it can withstand high temperatures over 650℃ for a long time. Key components (such as wire rope, bearings) are made of high-temperature resistant and anti-wear materials.
Intelligent clamping system: Configured with rigid/flexible/rotary clamps, hydraulic/electric clamping mechanism for stable gripping, and some models are equipped with an auto-centering function.
High-precision operation: frequency conversion speed control + encoder positioning (±10mm), equipped with anti-skew and double braking system to ensure accurate and safe handling.
Intelligent control integration: PLC + frequency conversion coordinated control, support for remote monitoring, fault diagnosis, and MES system docking, to realize automated operation.
Multiple safety protections: overload protection, high temperature alarm, and emergency power supply (optional).
Efficient handling: suitable for continuous casting billet, heating furnace feeding, rolling line transfer, and other scenarios.
Modular structure: easy to transport, install, and maintain, shortens on-site construction period; personalized configuration can be provided according to the layout of the steel plant, slab size, and other needs.

Application

Continuous casting cross-hauling: for the transfer of high-temperature slabs from the cutting area of the continuous casting machine to the slab storage or directly to the rolling shop.
Heating furnace loading: precise loading of slabs from the storage area or the continuous casting machine into the heating furnace for the reheating process.
Rolling line feeding: Provide a continuous and stable supply of slabs for hot rolling or medium thickness plate production line.
Finished product transfer: Transfer finished slabs after rolling to the finishing area or the finished product warehouse.
Special process handling: to meet the needs of transferring slabs for special processes such as regrinding, printing, weighing, and so on.
Scrap Blank Recycling: Handle the recycling and transferring of unqualified slabs.
