In this paper, testing results on the tin-alloyed cast iron cylinder-blocks for trucks are presented. The results obtained in the laboratory and in the mass production indicate that addition 0.05% Sn to melted iron HT20-40 containing 0.25-0.35% Cr can increase quantity of pearlite which occurs at the interior wall of the cylinder-blocks over 90%; its hardness is considerablly increased; undercooled layer is decreased; sensibility of the cross-section is decreased; permitted range of the chemical...

In this paper, testing results on the tin-alloyed cast iron cylinder-blocks for trucks are presented. The results obtained in the laboratory and in the mass production indicate that addition 0.05% Sn to melted iron HT20-40 containing 0.25-0.35% Cr can increase quantity of pearlite which occurs at the interior wall of the cylinder-blocks over 90%; its hardness is considerablly increased; undercooled layer is decreased; sensibility of the cross-section is decreased; permitted range of the chemical composition is increased; soundness and anticorrosion is inproved too; and at the same time, the technique of mechanical cutting is satisfied. Therefore, tin-alloyed cast iron for cylinder-blocks surely has long-live service. Inoculated iron by addition Sn is discussed in detail. According to the refinement of eutectic cells, improvement of sensibility of the cross-section, decreasing tendency to chilling, decreasing the amount of undercooled graphite and increasing mechanical properties, in comparision with the iron no added with Sn, it indicates that Sn can inoculate melted iron. Besides, The formation of the undercooled layer in the cylinder-blocks and the effect on the layer by the addition of Sn have been explained.

本文报导了加锡铸铁制作汽缸体的试验工作。实验室工作和生产试验表明,在原有HT20-40牌号含铬的铁水中,附加 0.05%的锡,可使汽缸体缸筒内壁的珠光体数量提高到90%以上,硬度有明显的提高,过冷层厚度减少,并且减少了汽缸体的断面敏感性,扩大了允许的化学成分范围,致密度和耐腐蚀性能也有所改善;同时也能满足机械加工的工艺要求。从而,可以显著地提高汽缸体的使用寿命。 文中指出,加锡对铸铁有孕育作用。从细化共晶团、改善断面均匀性、减少白口倾向、减少过冷石墨和提高机械性能几方面,与不加锡的铸铁进行对比,论证了锡的孕育作用。此外,还对汽缸体过冷层的形成以及加锡可使其减少的原因进行了探讨。

In this paper, the investigation of the test procedure of the production of compacted graphite cast iron with high-sulfur melted iron in the cupola has been introduced, treated by XtMg 5 - 6 alloy. The present paper has described the production technique and control method, resera-ch on chilling tendency and compacted effect failure of this Compacted graphit iron hao been andertaken, other existing proptemsof this compacted graphit iron has been poinded out also.
