Hot Billet Delivery Trailer
Insulation material selection: lightweight materials that are high-temperature resistant (≥1200℃), have low thermal conductivity, and are resistant to thermal shock, balancing insulation performance with structural weight.
Sealing technology: high-temperature sealing between the compartment cover and the vehicle compartment to prevent heat radiation and convective loss.
Temperature monitoring: some high-end models are equipped with temperature sensors to monitor changes in the steel billet temperature in real-time during transportation.
Hydraulic system: provides sufficient power to open, close, and position the compartment cover, meeting stability requirements in high-temperature environments.
Hot Billet Delivery Trailer The core goal is to increase the temperature of the billet into the furnace, thereby reducing energy consumption such as gas, shortening the heating time of the billet, and ultimately effectively improving production efficiency and creating higher economic benefits for enterprises.
Description of the structure of the equipment
Insulated compartment
As the core component of the equipment, the thermal insulation box is composed of three parts: thermal insulation box, hot billet and billet support. Among them, the insulation box includes a fixed box at both ends, a top cover box and a side box, and its specific size and vehicle weight can be flexibly customized according to the billet specifications required by the steel mill to be transported.
The exterior of the compartment is made of high-quality steel pipes to build a load-bearing skeleton, and the interior is laid with high-temperature resistance, excellent thermal insulation performance and easy-to-fill insulation materials, and the effective insulation thickness is maintained at 100-150 mm. The design is to form a fully enclosed thermal insulation space by completely blocking the conduction of the thermal bridge; At the same time, in order to strengthen the insulation effect and reduce heat loss, the fixtures of the insulation material adopt a built-in design to further weaken the thermal bridge effect.
Considering the different fixture specifications of each steel mill for loading and unloading billets, the insulation box adopts a foldable open structure - when closed, it forms a closed insulation body, and when opened, the upper cover and side compartment plate can be fully expanded and lower than the upper plane of the semi-trailer girder, which not only expands the loading and unloading space of the billet, but also expands the operator's field of vision, which is convenient for efficient and safe loading and unloading operations.
Automatic opening and closing mechanism
The mechanism is composed of a four-link transmission mechanism, hydraulic drive system and other components, with a unique structural design and reasonable clearance control, to achieve smooth opening and closing synchronization and no jamming, even if it is heated and deformed, there will be no jamming problem. The hydraulic system has a reliable self-locking function, which can ensure that the mechanism will not slip off when the incubator is stagnant at any position during the opening and closing process, and can prevent the opening from accelerating after crossing the center of mass. The system is also equipped with an overload protection device to improve operational safety.
Electrical system
The electrical system integrates electrical wiring, battery, incubator opening and closing control box, remote control, reversing display system (including camera), rear lamp and sound and light alarm device, supporting wired and wireless dual control modes, flexible and convenient operation, and adapting to the needs of different operation scenarios.
Core Advantages of the Equipment
1. Driven by the main vehicle's power take-off system to operate the hydraulic system, enhancing the utilization of the main vehicle's resources while effectively reducing fuel consumption, balancing practicality and economy.
2. The insulated compartment uses hydraulic-driven opening and closing, enabling automated control and supporting remote operation from under the vehicle, significantly reducing manual labor intensity and improving operational efficiency.
3. Excellent insulation performance; even when the internal temperature reaches over 1000℃, the external surface temperature of the compartment can still be controlled around 30℃, ensuring transportation safety. Hot steel billets can remain in the compartment for an hour with virtually no loss of surface temperature.
4. Features a dedicated structural design that securely fixes the insulation material, effectively preventing it from falling off during long-term high-temperature operations, thereby extending the equipment's service life.
5. Outstanding safety and environmental performance; the enclosed insulated compartment isolates high temperatures from the surrounding environment, protecting roadside vegetation and ecology while eliminating the risk of burns, creating a solid safety barrier during operations.
6. Significant energy-saving and consumption-reducing effects; by minimizing heat loss during the transportation of hot steel billets, the furnace entry temperature of the billets is increased, avoiding or reducing the energy and time required for secondary heating, thereby substantially lowering production costs and improving economic efficiency for steel plants.
7. Strong adaptability; it can be flexibly adjusted according to different specifications and types of steel billets, meeting the diverse transportation needs of various steel plants.
