Why Buy Metallurgical Cranes？
As the key and important equipment necessary for the safety and normal production of the metallurgical industry, metallurgical cranes have always been highly valued by people for their reliability, safety and advancement.
Metallurgical cranes generally refer to foundry cranes, bin feeding cranes, slab handling cranes, steel coil clamp cranes, disk cranes and other bridge cranes that serve metallurgical plants at a higher level.
1. Monitoring sensor control technology.
The performance and reliability have been greatly improved. With the advancement of science and technology, various monitoring and sensor control technologies have been widely used in metallurgical cranes, which greatly improves the performance of the crane and makes the metallurgical crane simpler than before. In a sense, the material handling tool has become the current logistics and information flow comprehensive transmission equipment.
1.1 Weighing device: A digital weighing device is installed on the casting crane. The small display screen is placed in the cab, and the large display screen is set under the main end beam, facing the ground, so that the weight of molten steel in the ladle can be displayed at any time. The data is connected to In the computer room, on the one hand, the daily output can be accumulated, and on the other hand, the amount of molten steel that should be contained in the steel ladle can be determined according to the size and number of continuous slabs, so as to reduce waste. With the application of various large-scale high-precision electronic scales, metallurgical cranes can also perform functions such as output statistics, overload power-off and alarms while carrying objects.
1.2 Fault display, recording and printing devices In continuous production iron and steel enterprises, time is money. After a crane breaks down, it is hoped that the repair time will be kept to a minimum. The fault display device can display the names of the parts and parts that are failing on the display screen in the driver's cab, and the maintenance personnel can immediately know the fault location, which can greatly shorten the maintenance time.
For electrical and mechanical parts that are prone to failure, the crane manufacturer sets fault display points according to relevant requirements. Once the monitored parts fail, they will be displayed on the screen to avoid the occurrence of larger failures. In addition to the display function, the device also has the functions of recording and printing, which is needed to find the cause of the failure and implement the checking responsibility.
1.3 Two, three-dimensional positioning device The position of the spreader in space can be displayed on the display screen in the driver's cab through this device, and the positioning accuracy can be controlled below ±10mm, which can meet the technological requirements of various automatic operation lines. The driver can intuitively determine whether the spreader or the object has reached the position that the object should reach through the numbers displayed on the display screen, which greatly shortens the lifting time and avoids the shaking of the object, which can effectively improve production efficiency.
1.4 Anti-collision device In the past, in order to prevent two cranes from colliding, only limit switches and buffers were installed. Now there are laser or radar anti-collision devices. One crane is equipped with a launching device, and the other crane is equipped with a receiving or reflecting device. When the preset distance is reached, an alarm is issued to avoid collisions.
1.5 Safety brake When lifting important objects, such as: nuclear materials, liquid metal, generator rotors of large hydropower stations, etc., a safety brake is set on the reel of the main hoisting mechanism of the crane. One pair, two pairs or even three pairs of pads can be set on the rim of the flange on one side of the reel according to the requirements of the braking torque, which are controlled by a special hydraulic station. When starting, the safety brake is opened first, and the working brake on the high-speed shaft is opened later. When braking, the working brake brakes first, and the safety brake brakes after a few seconds.
The function of the safety brake is to ensure that when any transmission part in all transmission chain links between the working brake and the safety brake is damaged or broken, the suspended objects can be safe. Properly apply various monitoring and sensing technologies to cranes to realize wired or wireless control of metallurgical cranes.
2 Programmed control technology, remote control technology used in special environments With the development and perfection of computer software and hardware technology, it has become possible to realize program-controlled cranes. In order to complete various work tasks more accurately and instantly, various metallurgical cranes are linked with the main control equipment through wired or wireless.
Remote control metallurgical cranes are generally used in some dangerous work areas with high dust and high pollution, while program-controlled metallurgical cranes are generally used in some occasions with high operating efficiency.
3 Spreader diversity. Metallurgical enterprises need to have: bridge feeding crane, material box feeding crane, casting crane, ingot crane, soaking furnace clamp crane, soaking furnace uncovering crane, slab clamp crane, rigid rake crane, (including disk ) Steel coil tongs, cranes and other cranes to complete the process, while using continuous casting→continuous rolling process, the metallurgical plant only needs to have several cranes such as material box feeding, casting, slab tongs, and steel coil tongs. The material handling in the whole process is completed, which greatly simplifies the crane type.
Due to the diversity of requirements for metallurgical products, various special spreaders are also applied, such as horizontal roll spreaders, vertical roll spreaders, self-aligning vertical roll spreaders, cover lifters, and L-shaped hooks for finishing spans. The steel plate spreader, C-hook, and the hook that can be rotated by human control can be used together to realize various operating functions.
4 Rationalization of ergonomics and comfortable operating environment With the progress of society, the awareness of environmental protection and labor protection has increased, and the requirements for ergonomics and comfortable operating environment have been raised to higher requirements in the design process of metallurgical cranes.
Such as: the driver's cab is equipped with cold and warm air conditioners, heat insulation protection, wireless remote control on the ground, wired and wireless communication on the car, aviation seats, driver's lounge, all the upper and lower cranes use inclined ladders, and the electrical room is equipped with heat insulation protection And cooling fan, anti-slip measures are taken for narrow pedestrian passages, and hanging cages are installed for frequent maintenance parts, etc., which provide a better working environment and conditions for operation and maintenance personnel.
Especially the double-walled, double-glazed driver's cab is used in conjunction with reclining aviation seats, heating and cooling air-conditioning, wired and wireless communications. It has played a very good role in improving the working conditions of drivers, increasing work efficiency and reducing work mistakes.
