(一)前言铸锭是炼钢工作中的最后一道重要工序。根据这几天的报告,我们可以看到成万吨的钢由于铸锭工作不好而遭到损失,由此可以知道钢锭结晶的重要性。钢锭的结晶是很复杂的,为了更好的研究,应当把钢锭剖开,但是这种方法是很费时间的,同时在试验室条件下作此试验也有困难,因此用一些简单设备和代用品来研究钢锭的结构方面的问题,是具有极大意义的,今天我要介绍的,是用石蜡作浇铸试验的情况。
(A) of the preface ingot steelmaking work is the last important process. According to these few days’ reports, we can see that tens of thousands of tons of steel have been lost due to poor ingot work, so we can know the importance of ingot crystallization. The ingot crystallisation is complicated and the ingot should be cut open for better research, but this method is time consuming and difficult to do with this test under laboratory conditions. Therefore, with some simple equipment and alternatives It is of great significance to study the structural aspects of steel ingots. What I will introduce today is the case of casting tests with paraffin wax.
