随着全球产业结构的调整,中国工具产品已进入世界舞台,成为我国出口创汇的重要成员。然而,中国工具产业脱胎于手工作坊,属劳动密集型产品。相当长的一段时期内,工具行业受产品质量与生产成本的影响制约了自身的发展。影响工具质量的关键工序是热处理,随着多种先进热处理设备的问世,热处理工艺不断更新。其中工具产品高频热处理生产线的诞生为国内工具企业取得规模效益提供了良好的条件。下面以一种高频热处理生产线为例(图1、2)简要说明其特点: 工具产品高频热处理生产线优点是:与一般盐浴炉等热处理设备相比,电效率高,相同批量可节电1/3;高频热处理设备环境污染少,不需“三废”处理,劳动强度低;加热均匀,升温时间短,氧化皮少。 淬火机床为高频热处理生产线的重要设备,它能
With the adjustment of the global industrial structure, China’s tool products have entered the world stage and become an important member of China’s export earning foreign exchange. However, China’s tool industry is born out of manual workshops and is a labor-intensive product. For a long period of time, the tool industry is constrained by its own development due to product quality and production costs. The key process affecting tool quality is heat treatment. With the advent of a variety of advanced heat treatment equipment, the heat treatment process is continuously updated. One of the high-frequency heat treatment tool production line for the birth of the domestic tool companies have achieved economies of scale provided good conditions. The following to a high-frequency heat treatment production line as an example (Figure 1, 2) Brief description of its characteristics: High frequency heat treatment tool production line advantages are: with the general salt bath furnace and other heat treatment equipment, high electrical efficiency, the same batch can save energy 1/3; high frequency heat treatment equipment less environmental pollution, without “three wastes” treatment, low labor intensity; heating evenly, heating time is short, less scale. Quenching machine for high-frequency heat treatment production line of important equipment, it can
