The invention discloses a preparation method of an environment-friendly elevator balancing weight. The preparation method comprises the following steps of S1, raw material selection; S2, raw materialpretreatment; S3, mixing and weighing; S4, cold pressing; S5, heating and hot pressing; and S6, cooling and discharging. The invention further provides the environment-friendly elevator balancing weight prepared through the method. According to the environment-friendly elevator balancing weight, the defects that a poured cement block is too large in weight and size and short in service life can beovercome, the density of a finished product can reach about 7.4, the service life is long, the defect that pig iron is prone to being broken under external force impact during casting can be overcome, and high toughness is achieved; and the adopted raw materials are iron shavings, particle steel, waste scrap iron and the like, and the environment-friendly elevator balancing weight is low in production cost, high in production efficiency and environmentally friendly.
本发明公开了一种环保型电梯配重块的制备方法,包括以下步骤:S1、原料选择;S2、原料预处理;S3、混合及称重;S4、冷压;S5、加热及热压;S6、冷却下料。本发明还提供了由所述的方法制备的环保型电梯配重块。本发明的环保型电梯配重块,能够克服浇筑水泥块同重量体积过大,使用寿命短的缺陷,成品密度能够达到7.4左右,且使用寿命较长,也能克服生铁铸造容易在外力冲击下破碎,具有较强韧性,而且所用原料为铁刨花、粒子钢、废铁屑等,又具有生产成本较低,生产效率高,对环境友好。
