Abstract
The invention relates to high-carbon low-silicon malleable cast iron, and is characterized in that the cast iron comprises the following raw materials by the mass percentage: 2.6-2.8% of C, 1.1-1.35% of Si, 0.4-0.7% of Mn, 0-0.20% of S, 0-0.20% of P, 0.002-0.01% of Bi, 0.007-0.015% of Al, and the balance Fe. The high-carbon low-silicon malleable cast iron has the beneficial effects that the high-carbon low-silicon malleable cast iron is strong in impact resistance, good in wear resistance, and reasonable and simple in formula, and the strength, toughness and wear resistance of castable parts can be greatly improved.
Description
Technical field
The present invention relates to cast member technical field, relate in particular to the low silicon malleable iron of a kind of high-carbon.
Background technology
In ancient times, people make coin, sacrificial utensil, weapons, instrument and some life appliances with foundry goods; In modern age, foundry goods is mainly used to the blank of making machine component, and some precision casting also can directly be used for the component of making machine.According to statistics, foundry goods occupies very large proportion in engineering goods, accounts in 70%-90%, borings lathe and accounts in 70%-90%, rubber plastic machinery and account in 60%-90%, coal mine machinery and account for 60%-70% as accounted in tractor in the 60%-80%, oil engine of complete machine weight.Foundry goods is just being brought into play huge latent effect in modern technologies development, no matter is that aerospacecraft enters space, or intelligent robot steps into deep-sea; Also the renewal that is no matter computer installation is at a tremendous pace, or the develop rapidly of engineering science technology, all be unable to do without using and supporting of high quality casting.Foundry goods also has close relationship with daily life, as the door knob of frequent use, door lock, radiator, upper and lower conduit road, iron pan, stand for gas stove, flatiron etc., is all also foundry goods.The weight of foundry goods and size range can non-constant widths, and the lightest only has several grams, the heaviest reached 400t, and the thinnest only have 0.5mm, the thickest 1m that exceedes, length can be by several millimeters to tens meters, and can meet the service requirements of each industrial sector.Based on this, now study the low silicon malleable iron of a kind of high-carbon, rationally, intensity, toughness, wear resistance that can foundry goods be greatly improved formula.
