What are the advantages of lightweight hot metal cars in practical applications?
- Enhance effective load capacity and improve transportation efficiency
On the premise of maintaining the rated axle load of the factory roads, the vehicle’s weight is reduced and it can carry more molten iron.
For example, with the same number of axles and the same total weight allowed on the same road, if the self weight is reduced by 5 tons, an additional 5 tons of molten iron can be transported.
Reduce the number of transfer trips, improve the turnover efficiency of molten iron tanks, reduce the temperature drop of molten iron caused by waiting, and reduce energy consumption in the steelmaking process. - Reduce power consumption and save energy (electric vehicle models have more significant benefits)
Reduced self weight, reduced starting, climbing, and turning resistance:
-Fuel version: reduced fuel consumption, continuous low-speed operation under heavy load in the factory area, significant long-term fuel cost savings;
-Electric version: With the same battery capacity, it has a longer range, reduces charging frequency, lowers electricity costs, and can also choose smaller capacity batteries to further reduce costs and weight, forming a positive cycle. - Reduce damage to the factory road surface and lower infrastructure maintenance costs
The roads in the steel plant area have been subjected to heavy loads and compaction for a long time, reducing their own weight and decreasing the pressure on the road surface
-Reduce road cracking, settlement, and potholes;
-Extend the service life of hardened roads in the factory area, reduce road maintenance downtime, and ensure continuous production;
-The renovation project of the old factory area is particularly prominent. The original road has limited bearing capacity, and lightweight vehicles can directly reuse the old road surface without large-scale renovation. - Improve vehicle mobility and adapt to small factory areas
Reduced self weight and decreased vehicle inertia:
-More flexible starting and turning, with slightly smaller turning radius requirements, suitable for narrow passages and multi lane factory areas inside the workshop;
-Shorter braking distance and improved emergency braking safety in high temperature and high-risk scenarios; - Reduce vehicle fatigue load, extend equipment life, and minimize malfunctions
The self weight of vehicles is an important source of continuous alternating loads. Steel mills frequently start and stop, and bumpy roads:
-The self weight is reduced, and the alternating stress borne by the frame, suspension, axle, tire, and ear axle locking mechanism is reduced;
-Reduce the probability of frame cracking, suspension damage, and tire overheating and wear;
-Extend the overhaul cycle, reduce downtime for maintenance, and enhance the continuous production capacity of steel mills. - Transportation and installation advantages, overseas export projects benefit more (suitable for Central Asian export scenarios)
After lightweighting, the overall weight of the vehicle is reduced:
-After the equipment leaves the factory, it is easier to meet the weight limit for container/large item transportation and reduce the logistics cost for large items when shipped by road or sea;
-The difficulty of on-site hoisting and installation is lower, and there is no need for ultra large tonnage cranes on site, especially suitable for overseas new metallurgical projects. - Additional benefits: reduced load on braking and cooling systems
Light weight, reduced load on the braking system, and decreased brake heating; At the same time, the cumulative effect of vehicle thermal load is reduced, and with the help of thermal insulation protection, the thermal fatigue risk of tires, hydraulic pipelines, and electrical components is further reduced.
