一、问题的提出普通灰铸铁和低合金灰铸铁是制造玻璃模具的传统材料,近年来国内外又推广了蠕墨铸铁玻璃模具。国外还广泛采用连续铸造法生产口模和某些行列机备料的异形棒材。这种铸造方法在我国已开始应用,並在某些工厂投产。氧化起皮是玻璃模具主要失效形式之一,随着行列机机速的提高,模具的热平衡温度将在原有基础上有所增加,氧化起皮的矛盾自然会更加突出。影响铸铁抗氧化性的因素是很多 First, the problem raised Ordinary gray cast iron and low alloy gray cast iron is the traditional material for the manufacture of glass molds, in recent years at home and abroad have also promoted compacted graphite cast iron glass mold. Abroad is also widely used continuous casting method to produce the die and some of the ranks of special-shaped rod material preparation. This casting method has been applied in our country, and put into operation in some factories. Oxidation of the skin is one of the main forms of failure of glass molds, with the ranks of machine speed increases, the mold heat balance temperature will be increased on the basis of the original, the contradictions of oxidation and peeling will be more prominent. Affect the oxidation resistance of cast iron is a lot of factors
