压块机是利用压缩空气作动力,钢屑加热采用简易煤气炉,以粉煤为主要燃料,它与反射炉比较,具有结构简单、制造方便、易操作,加热温度高,无烟等特点。压块机有三个气缸,可将加热后体积为500×400×400毫米~3的钢屑压缩成250×200×250毫米~3的压块。生产率班产为5吨,压块形状整齐易于运输和回炉熔炼。缺点是煤气发生炉密封不便。加热炉火力不均,有死角,有时料需翻转。文中还就该厂自制的压块机与国内轴承行业兄弟厂采用的压块机作了对比,列出了经济效果。附图2幅。
Briquetting machine is the use of compressed air as power, steel scrap heating with a simple gas stove, pulverized coal as the main fuel, compared with the reflex furnace, with simple structure, easy manufacture, easy operation, heating temperature, smoke-free features. Briquetting machine has three cylinders, can heat the volume of 500 × 400 × 400 mm ~ 3 steel scrap compressed into 250 × 200 × 250 mm ~ 3 compact. Production productivity of 5 tons of production, tidy briquette shape and easy transportation and melting furnace. The disadvantage is the gas stove seal inconvenience. Heating furnace uneven, dead ends, sometimes expected to be reversed. The article also makes the factory-made briquetting machine and the domestic bearing industry Brother plant used by the contrast of the briquetting machine, lists the economic results. Figure 2 Photo.
