Preparation process of environmental-friendly high-density counterweight filler

The invention discloses a preparation process of an environmental-friendly high-density counterweight filler. The preparation process comprises the specific steps of carrying out feeding, carrying out heating, carrying out discharging, carrying out weighing, carrying out conveying, carrying out primary hot pressing, carrying out secondary heating and carrying out hot pressing and carrying out stacking. According to the preparation process, the high-temperature hot pressing process and the hot die forging process are combined, the density of a product can be effectively improved, waste steel scraps, waste iron scraps, particle steel and other waste raw materials are adopted as raw materials, resource recycling is achieved, and energy conservation and environmental protection are achieved. 本发明公开了一种环保型高密度对重块的制备工艺，具体步骤包括上料、加热、出料、称重、送料、一次热压、二次加热与热压和码垛。本工艺采用的是高温热压与热模锻工艺相结合的方式，能够有效提高产品的密度，且原料采用的是废钢屑、废铁屑、粒子钢等废旧原料，实现资源再利用，节能环保。
