去年在英国参观了英国工业炉展览会,了解了英国工业炉的状况,水平较高,其中有不少新技术,对照我国情况,确有不少值得学习参考之处,现将其特点作扼要介绍: 1.普遍采用最先进的无氧化炉与真空电炉新技术。热加工方面早已采用了无氧化加热。当前,以氮气取代吸热式、放热式保护气直接通入炉内是一个新发展。六十年代,真空电炉已 Last year, I visited the British Industrial Furnace Exhibition in the UK and learned about the status of the British industrial furnace. There are quite a lot of new technologies in place in the United Kingdom. There are quite a few worthy of reference for reference to our situation. Introduction: 1. The most advanced non-oxidation furnace and vacuum furnace new technology. Thermal processing has long been used without oxidation heating. At present, it is a new development to replace the endothermic and exothermic protective gas with nitrogen directly into the furnace. Sixties, the vacuum furnace has been
