一、序言以1973年石油危机为转折,世界经济出现低增长趋势。这就产生了在高速发展时代予想不到的问题,世界从资源有限时代向省资源、省能时代转变。最近,各国都把石油使用量的削减开支开始纳入国家计划,提出对策,并不断与以实施。在这当中,我们热处理工作者从多方面研究省资源、省能对策。这里我们报告一下采用新型筑炉材料的省能热处理炉的筑炉及其经济性。
I. Preface Taking the oil crisis of 1973 as a turning point, the world economy shows a trend of low growth. This created a problem that could not be expected in the era of rapid development. The world shifted from a time limited resource to an provincial resource saving time. Recently, all countries started to incorporate the reduction of oil consumption into their national plans, put forward countermeasures and continued to implement them. Among these, our heat-treatment workers study resources in different provinces and save energy. Here, we report on the furnace construction and economy of the energy-saving heat-treatment furnaces with new building materials.
