- Supply form of Hardox 450 steel plate
(1) Rich specification selection
Hardox 450 steel plates are available in a variety of specifications, with thicknesses generally ranging from 3mm – 130mm, widths usually ranging from 1500mm – 2800mm, and lengths can be customized according to customers’ specific needs. For example, in some special engineering applications, customers may require specific lengths of steel plate to meet precise design requirements, and the customizable features of Hardox 450 steel plate are well suited to meet this need.
(2) Various surface treatment methods
Hardox 450 steel plates are available in a variety of surface treatments, including hot-rolled raw skin, pickled raw skin, shot blasting, etc. The hot-rolled raw skin retains the original surface state of the steel plate during the hot rolling process and has a certain roughness; the pickled raw skin removes the oxide layer and impurities on the surface through pickling, presenting a smoother surface; shot peening can increase the The hardness and roughness of the steel plate surface improve its wear resistance. These different surface treatment methods can meet various usage requirements. Whether you require a higher surface finish or pursue better wear resistance, you can find a suitable choice.
(3) Reliable packaging method
Hardox 450 steel plates are generally packaged in bare plates or wooden pallets. Bare plate packaging is suitable for short-distance transportation and situations where surface requirements are not high; wooden pallet packaging can provide better protection during long-distance transportation and prevent steel plates from being impacted and worn during transportation. This reliable packaging method effectively protects the integrity and quality of steel plates during transportation and reduces the risk of damage caused by transportation.
- Wide application of Hardox 450 steel plate
(1) Applications in the field of engineering machinery
In the field of construction machinery, Hardox 450 steel plate performs well in excavator bucket applications. For example, the bucket plate of a certain brand of large excavator is made of Hardox 450 steel plate. During long-term excavation operations, when faced with various hard earth and rock materials, the wear degree of the bucket plate is significantly lower than that of similar products using ordinary steel plates, which greatly extends the time. The bucket plate replacement cycle is determined.
In addition, the crusher liner uses Hardox 450 steel plate, which can withstand high-intensity crushing impacts, which not only reduces the frequency of liner replacement, but also improves the working efficiency of the crusher. After a certain model of crusher was replaced with Hardox 450 steel plate liners, the crushing output increased by about 15%.
(2) Key roles in mining equipment
In mining equipment, Hardox 450 steel plate also plays an important role. The mine unloading hopper uses this steel plate, which can withstand the frequent impact and friction of the ore, and its service life is more than doubled.
The crusher blades use Hardox 450 steel plates. When crushing hard ores, the wear rate of the blades is significantly slowed down, reducing equipment maintenance costs. A mine’s crusher uses Hardox 450 steel plates for its blades, saving hundreds of thousands of yuan in annual maintenance costs.
(3) Improvement of efficiency of transportation equipment
When it comes to hauling equipment, Hardox 450 steel plate provides stronger protection for truck bodies. After the truck body of a transportation company adopts this steel plate, the wear and tear of the truck body is greatly reduced during long-term cargo transportation, the appearance is maintained in good condition, and the load-bearing capacity of the body is improved.
In the application of excavator bucket plates, Hardox 450 steel plates enhance the wear resistance and strength of the bucket plates, making the excavators more stable and reliable when loading and unloading cargo, and reducing work interruptions caused by bucket plate damage.
