随着祖国矿山建设事业的迅猛发展,对矿用自卸汽车翻斗用钢提出越来越高的要求。以本溪钢铁公司南芬露天铁矿为例,该矿是我国目前大型铁矿之一。矿石颗粒度大,硬度高,使用条件恶劣,所用自卸车辆大多为苏修别拉斯—540、玛斯—525两种重型汽车。由于翻斗用钢强度低(别拉斯—540用16Mn,玛斯—525用A_3)、使用寿命短(别拉斯斗用1年左右,玛斯斗用5个月),近年来已成为该矿车辆使用的“老大难”。以该矿汽车运输量2200万吨计,
With the rapid development of the mining industry in the motherland, more and more high demands are placed on dump trucks for dump trucks. Taking Benxi Iron & Steel Nanfen Open-pit Iron Mine as an example, the mine is one of the largest iron mines in China. Large particle size, high hardness, poor service conditions, most of the dump trucks used for the Soviet revisionist Balsi-540, Mas-525 two heavy vehicles. As the dump steel with low strength (Balsa-540 with 16Mn, Masi -525 with A_3), short service life (Balsa bucket with about 1 year, Masi bucket with 5 months), in recent years has become the Mine vehicles used to “unsolved”. The mine car traffic volume of 22 million tons,
