前言生物能——沼汽的产生利用有机废物(尿粪等),经过密闭发酵后所得的气体,这种气体含有大量的甲烷,所以是一种活性极强的渗碳剂。钢经过渗碳处理可以获得坚硬耐磨的表面,大大地提高工件的寿命,农具中许多工件都常采用渗碳处理,如铧犁犁壁和滚珠轴承等。渗碳有固体法,液体法及气体法,而气体法则是最先进的渗碳方法。为了利用农村沼汽及改进渗碳处理工艺,我所与湖北省工业厅生物能利用研究组进行了钢的表面渗碳试验,证明了沼汽渗碳不但具备一般气体渗碳的优点,而比石油类液体(如煤油)经高温分解后所得的渗碳气体有较高的渗碳效率。农村的沼汽既价廉又便利,渗碳设备亦简便,在我
Preface Bioenergy - The production of biogas utilizes organic waste (eg, manure, etc.). After aseptic fermentation, the resulting gas contains a large amount of methane and is therefore a highly active carburizing agent. Steel after carburizing can get a hard and wear-resistant surface, greatly improving the life of the workpiece, many tools are often used carburizing farm tools such as plow plow wall and ball bearings. Carburization of solid law, liquid law and gas law, and gas law is the most advanced carburizing method. In order to utilize rural marsh gas and improve carburizing treatment process, I conducted a surface carburizing test with bio-energy utilization research group of Hubei Provincial Department of Industry to prove that not only does carburizing carburizing have the advantages of general gas carburizing, Carburizing gases obtained from the pyrolysis of petroleum liquids (such as kerosene) have higher carburizing efficiency. Rural biogas is cheap and convenient, carburizing equipment is also simple, at me
