延展性的强度是铸造铸铁井盖的特色

铸铁井盖相对容易铸造,因为它容易倾倒并且不像钢一样收缩。 这意味着它将容易地填充给定模具中的复杂空隙并且需要更少的熔融材料。

A cast iron cap is relatively easy to cast because it is easily dumped and does not shrink like steel。 This means that it will easily fill the complex void in a given mold and require less molten material。

浇注钢可能会更加困难。 它比铁水流动性更差,对模具材料更具反应性。 它在冷却时也会收缩更多,这意味着更多的熔融材料需要倾倒,通常会被称为“提升管”,这是一种称为“提升管”的过剩储存器。

It may be more difficult to cast steel。 It is worse than the fluidity of the molten iron, and is more responsive to the mold material。 It also shrinks more when it's cooled。 This means that more molten materials need to be dumped。 It is usually called "riser", which is an excess memory called a riser。

此外,铸件通常不会在其内部结构中均匀地冷却。 外部区域和较薄部分将以比内部区域和体积较小的部分以不同的速率冷却和收缩 - 通常产生只能通过热处理减轻的内部张力或应力。

In addition, the casting is usually not uniformly cooled in its internal structure。 The outer area and the thinner part will be cooled and contracted at different rates than the inner part and the smaller part, usually producing internal tension or stress that can only be reduced by heat treatment。

钢更容易收缩应力,在某些情况下,这些张力可能导致断裂。 总体而言,钢铁在整个铸造过程中需要更多的关注和检查,从而使管理生产的资源更加密集。

Steel is more likely to shrink stress, and in some cases these tensions may lead to fracture. In general, the iron and steel needs more attention and inspection throughout the casting process, thus making the resources more intensive in the management of production.

没有延展性的强度意味着材料将变得非常脆且容易断裂,根据最终的应用,可能需要对铸件进行加工,以达到特定的公差或产生所需的精加工。 至少,像门和跑步者这样的事情需要被削减和削减。 一些材料比其他材料更难加工。 可加工性是根据切割或研磨材料的容易程度来衡量的。

The strength without ductility means that the material will become very brittle and easy to fracture. According to the final application, it may be necessary to process the castings to achieve specific tolerances or to produce the required finishing. At the very least, things like doors and runners need to be cut and cut. Some materials are more difficult to be processed than other materials. Machinability is measured by the degree of ease of cutting or grinding materials.
