Scrap bucket is the core carrier of steel mill scrap transfer, and its transportation faces multiple working conditions, which are directly related to the production efficiency and operation safety. In terms of weight, scrap bucket loading fluctuates greatly, and the weight of the full bucket is concentrated, which requires high stability of the transportation equipment, and it is necessary to avoid the deviation or failure of the equipment triggered by the uneven weight.
Impact load should not be ignored; the instantaneous impact generated by the scrap loading, easy to wear equipment frame, wheels, may also affect the sealing of the barrel, increasing the risk of scrap spillage.
At the same time, the harsh environment of high temperature, dust, and corrosive gases in steel mills will accelerate the aging of equipment components, which puts forward strict requirements on the protective performance and durability of the equipment.
Electric transfer cart is a kind of on-site transportation equipment with storage battery as power source, without external traction device, widely used in workshops, short-distance material transfer within the factory, especially suitable for steel mills and other closed operation scenarios.
The core working principle is to supply power to the driving motor through the storage battery, the motor will convert the electric energy into mechanical energy, and then drive the wheels through the transmission mechanism to realize the start-stop, forward, backward, and steering of transfer carts.
Rail guided trolley is equipped with an independent control system, which can be operated by handle, remote control,l or PLC programming, and some high-end models support precise positioning to meet the needs of automated operations. Compared with the traditional fuel or traction transfer equipment, transfer cart is compact, flexible, and has no exhaust emission, which is suitable for the environmental protection and space utilization needs of steel mills.
Stable Load Capacity
10 ton load capacity accurately meets the loading requirements of regular steel mills’ scrap bucket, which can carry the weight of full bucket of scrap without wasting energy due to the excess rated load capacity of the equipment.
Automatic transfer carts usually adopts thickened frame and reinforced wheel design, which can effectively resist the instantaneous impact load when loading scrap, reduce the loss of equipment, safeguard the stability of the transportation process, and reduce the safety hazards such as the spillage of scrap.
Battery Driven
Battery-driven mode avoids the exhaust emission problem of traditional fuel equipment, and can work safely in closed workshops, furnaces, and other poorly ventilated areas, which is in line with the needs of steel mills to upgrade environmental protection.
At the same time, electric material transfer cart runs with low noise, which can improve the operating environment of steel mills and reduce noise pollution. In addition, the battery can realize fast charging, long life, and the backup battery can meet the 24-hour continuous operation, to avoid power interruptions affecting the production rhythm.
Optimize the Operation Process
The core line of steel scrap transportation is from the scrap yard to the steelmaking furnace area. 10 ton automatic transfer carts are compact in size and can flexibly shuttle between the scrap stockpile area, pre-treatment area, and furnace charging area without relying on a fixed track (some models can be adapted to the track), thus reducing the site constraints.
Its efficient transfer capacity can shorten the turnover cycle of scrap buckets, avoiding the production stoppage caused by untimely supply of scrap to the furnace, and at the same time, reducing manual intervention and improving the overall operational efficiency.
Electric scrap bucket cart is mainly divided into rail type and trackless type, which needs to be selected according to the site and operational requirements. Rail guided trolley runs on the preset track, with accurate positioning, stable load bearing, and low loss, suitable for fixed line and high-frequency transfer between the scrap yard and the furnace area, but it is not flexible enough, with high cost of track laying and maintenance, and limited by the site reconstruction to meet the demand of multiple lines.
Trackless transfer cart adopts tire drive, no need for track constraints, flexible route adjustment, suitable for multi-area, multi-station transfer, low difficulty of site reconstruction, and less investment in the early stage. However, its positioning accuracy and load stability are slightly less than rail guided trolley, making it more suitable for ground leveling and flexible line of operation scenarios. Both have their own focus, and need to match according to the need to protect the transfer efficiency.
This is the core application scenario of 10 ton battery powered cart. After loading the scrap in the scrap yard, battery powered cart can directly transport the full bucket of scrap to the charging area of the steelmaking furnace without the need for secondary transit, reducing material loss and transit time.
Some models support linkage with charging equipment to realize accurate docking of scrap drums, improve charging efficiency, and reduce labor support costs.
In the steelmaking gap or scrap pre-treatment stage, battery powered cart can transfer the scrap barrels to the temporary storage area and achieve accurate positioning and placement, avoiding the barrels from occupying the site in a messy pile, and at the same time, facilitating the subsequent rapid retrieval and optimizing the utilization rate of the site.
For the steelmaking rhythm of electric arc furnace (EAF) and converter (BOF), automatic transfer carts can realize the on-demand supply of scrap. EAF steelmaking requires high continuity of scrap supply, and transfer cart can guarantee raw material supply through high-frequency turnover.
BOF steelmaking requires precise distribution in line with the rhythm of blowing, and the flexible operation characteristics of transfer cart can be adapted to meet this demand and ensure stable operation of the steelmaking process.
