When looked at simply, the process of mining basically involves removing materials from the ground. However, when we look at mining in more depth, the actual extraction process can be quite complicated and involve a range of different plant and equipment.
And not only can it be complicated; it often involves a myriad of challenging factors and concerns including very large rocks, impacts, vibration, abrasion, fatigue, corrosion, to name a few.
While harder steel is highly desirable in a range of applications, especially in mining situations where abrasion resistance is key, the tempering process offered in certain of Bisalloy Steel’s product grades produces less brittle and more ductile steel without sacrificing all of the hardness.
The toughness of the BISALLOY® range of high hardness quenched and tempered steel grades means an even greater resistance to wear and abrasion. That is why quenched and tempered steel is particularly useful in machinery, plant and equipment where greater abrasion resistance combined with higher strength are necessary, such as mining, quarrying and earthmoving.
Mining involves component and equipment wear, with dump trucks, grader blades, ground engaging tools, buckets and bucket lips being just some of the mobile equipment that experiences high levels of wear. In terms of fixed plant, a range of applications use high strength quenched and tempered steel including bins, hoppers, chutes, screens, crushers and grizzly bars.
All of these applications are also found in underground mining applications where the level of safety is much more demanding. In these underground environments more consideration is given to loading, fatigue and impact – all areas where BISALLOY® steel can offer a solution.
On the mine site, output depends on continued availability. Bisalloy Steels’ quenched and tempered steel products have been developed to improve wear life and equipment up time and to extend component life.
When applied to production-vital components, these same technologies also increase performance, extend plant and machinery operational life, increase reliability, reduce component change-outs, increase resistance to wear and corrosion and reduce overall operating and maintenance costs.
