Abstract
The invention discloses a high-pressure-resistant pig iron casting comprising raw materials including the following components in percentage by mass: 0.125-0.3% of Si, 2.5-3.5% of C, 10-13% of Mn, 0.8-1.5% of Cr, 0.05-0.1% of Cu, 0.5-1.2% of Ni, 0.5-0.7% of Mo, less than or equal to 0.055% of S and less than or equal to 0.055% of P. By adopting the manner, according to the high-pressure-resistant pig iron casting disclosed by the invention, the proportions of the components of the casting are reasonably improved, so that the prepared pig iron casting is good in wear resistance and high in toughness, the compression resistance of the casting is particularly improved, the compression strength reaches 500-650 MPa, and the casting is suitable for manufacturing lathe beds of various machine tools and boxes.
Description
Technical field
The present invention relates to cast iron materials field, particularly relate to a kind of high pressure resistant iron casting.
Background technology
Iron casting is the one in the pig iron.Iron casting carbon content about 3%, siliceous about 2%.Section is Dark grey, and carbon is exist with the graphite form of sheet in the alloy of this iron.The pig iron is the iron-carbon that carbon content is greater than 2%, and commercial iron carbon content generally 2% ~ 4.3%, and containing elements such as C, SI, Mn, S, P, is with the product of iron ore through blast-furnace smelting.According to the difference of carbon existing forms in the pig iron, conversion pig, foundry iron and spheroidal graphite cast iron etc. can be divided into again several.Pig iron performance: the pig iron is hard, wear-resisting, castibility is good, but the pig iron is crisp, and compressive property is poor, thus limits the use range of iron casting.
