一、问题的提出推广密烘铸铁还是推广优质孕育铸铁?有些人一定认为提出这种问题是多余的外行话。本来嘛,密烘铸铁就是一种孕育铸铁。但在实际生活中我们确实碰到了这个问题。例如,《机械制造》1983年第7期发表了题为“密烘铸铁在我国推广的现实意义”的文章后,一些同志就片面地认为只有密烘铸铁才能解决他们的问题,不带“密烘”标签的优质孕育铸铁就解决不了问题。有人则一再要求重复引进这一技术。这可能是对密烘铸铁技术缺乏正确了解的缘故。本文试图对一些众说纷纭的问题加以分析阐明,供同志们参考,并希望
First, the question is proposed to promote dry cast iron or promote high-quality cast iron? Some people must think that raising such a problem is a superfluous layman. Originally, dense-baked cast iron was a kind of cast iron. But in real life we do encounter this problem. For example, after the article entitled “Realistic Significance of Doughing of Cast Iron in China” was published in the 7th issue of “Machine Manufacturing” in 1983, some comrades thought unilaterally that only the Bakelite could solve their problems without “dense.” Blast-free high-quality cast iron will not solve the problem. Some people have repeatedly asked for repeated introduction of this technology. This may be due to the lack of a correct understanding of the dense-baked cast iron technology. This article attempts to analyze and clarify some of the diverse issues for reference by comrades and hopes.
