我厂在无产阶级文化大革命运动中,承担生产100吨工矿自翻车。设计部门为了提高自翻车载重量,采用了低合金钢结构,例如:自翻车构架(图1)由于采用了薄壁低合金钢结构,较采用一般碳钢重量减轻 0．8吨左右,一个构架设计重量为1．2吨左右。每台自翻车铸钢件总重12吨,其中合金钢约9．7吨。 I plant in the proletarian cultural revolution, commitment to the production of 100 tons of mining self-overtaking. In order to improve self-rollover weight, the design department adopted a low-alloy steel structure, for example, the self-rollover frame (Figure 1) adopted a thin-walled low-alloy steel structure, The design weight is about 1.2 tons. Each self-turning steel castings total weight of 12 tons, of which about 9.7 tons of alloy steel.
