熔制孕育铸铁,第一项重要的工作是根据铸件特性及要求进行配料计算,与此同样重要的是熔化控制,二者配合才能得到良好效果。但由于冲天炉熔化过程及孕育处理过程中一系列的可变因素,使得熔化控制工作变得复杂化。炉前控制的任务就是要寻找并认识这些可变因素的变化规律,从而加以控制。我们在炉前控制工作中对某些问题作了一些对比和考查,拟在此提出讨论。为便于更清楚地了解下面所提出的问题,因此首先把配料情况大概介绍一下。
The first important job of melting and nurturing cast iron is to calculate the ingredients according to the characteristics and requirements of the castings. Just as important is the melting control, and the two work together to get good results. However, due to the melting process of the cupola and a series of variable factors in the inoculation process, the melting control work is complicated. The task of furnace control is to find and recognize the changing rules of these variables and control them. We have made some comparisons and examinations on certain issues in the furnace control work and we intend to put forward a discussion here. In order to facilitate a clearer understanding of the issues raised below, we will first outline the ingredients.
