近来陆续有资料介绍改进硅碳棒接头,以延长硅碳棒使用寿命的经验,如推荐用铝板制作接头(本刊,1974,5,11),以及用内径比硅碳棒两端稍大1～2毫米的不锈钢管或同等材质的材料加工制成(钢铁分析,1974,1,17)等。我们积多年的工作体会,向大家再介绍一种简易、耐用的接头:接头用厚约1毫米的铁皮(用一般废料边也可),按常法握制成钳形 Recently, one after another have information on improved silicon carbide rod joints, in order to extend the life of silicon carbide rod experience, such as the recommended aluminum joint production (1974, 5,11), and with a larger diameter than both ends of the silicon carbide rod 1 ~ 2 mm stainless steel pipe or made of the same material (steel analysis, 1974,1,17) and so on. We plot many years of work experience, to introduce you to a simple, durable connector: Connector with a thickness of about 1 mm of metal (with the general waste side can be)
