为了查明锡对钢材性能的影响,我们查阅了有关文献,并对我厂的现场数据行进了分析研究。本文就锡对钢材性能的影响和机理,含锡量的控制范围和改善含锡钢的途径等提出初步的看法。一、锡的潜在危险锡对钢的性能是有害的,因此历来是被严格禁止进入钢中。近来,由于锡的抗腐蚀作用和特殊性能又作为合金元素,加入量为0.25～1.87％。铸造用的冷铁和卡子采用镀锡防蚀、报废的机器连同锡基轴承压成整块和大量的镀锡件进入废钢,再加上锡在钢中尚无法去除,所以铸钢的含锡量有增长的趋势。
In order to find out the influence of tin on the properties of steel, we consulted the relevant literature and analyzed the field data of our factory. This article puts forward the preliminary opinions on the influence and mechanism of tin on the properties of steel, the control range of tin content and the ways to improve tin-containing steel. First, the potential danger of tin Tin is harmful to the performance of steel, it has always been strictly prohibited to enter the steel. Recently, due to the anti-corrosion effect of tin and special properties as an alloying element, the addition amount of 0.25 to 1.87%. Casting cold iron and clamps with tin anti-corrosion, scrapped machines along with tin-based bearings pressed into a large piece and a large number of pieces of tin into the scrap, coupled with the tin can not be removed in the steel, so the cast steel containing tin There is a growing trend.
