第一台四列式渗碳炉组在列宁汽车制造厂顺利运转了将近三年。它揭示,有必要安装另一台类似的炉组。与同行业各工厂所使用的同类型设备比较,这种设备的特点是生产率高,燃料和工艺气体消耗量较少。列宁汽车制造厂设计和制造了第二台四列式渗碳炉组,它将代替使用了二十多年的设备。 The first four-row carburizing furnace operated smoothly for nearly three years at Lenin Automotive Works. It reveals that it is necessary to install another similar furnace group. Compared with the same type of equipment used in the same industry and factories, this equipment is characterized by high productivity, fuel and process gas consumption less. Lenin Automotive Works designed and manufactured a second four-row carburizing furnace that will replace more than two decades of equipment.
