简介：本文主要介绍船用锻钢件在实际的生产加热过程中，加热温度控制能否达到工艺要求对产品质量产生的影响及如何控制好锻件加热温度进行分析及制定相关措施。

简介：温锻的使用前面我们已经讲到过在钣金加工过程中．冲孔、拉伸时对材料施加的应力可以在被加工材料的屈服强度以下．与其相比，锻压加工的压缩力如果达不到被加工材料屈服强度的3-5倍，就不能使材料充填到模具内腔的边边角角。

简介：采用金相显微镜、扫描电镜和透射电镜等分析研究了锻造温度对非调质易切削钢36MnVNS4组织和性能的影响。结果表明,高强度非调质易切削钢36MnVNS4的锻造组织由珠光体和块、网状铁素体组成;随着热锻温度的升高,其珠光体含量增多,晶粒度级别增大,珠光体团和珠光体片层间距减小,且材料表面硬度逐渐增大,强度升高,而延伸率和断面收缩率逐渐降低。

简介：“始”，这个字有点怪，表示“开始”，怎么是“女”字旁呢？这比和它差不多意思的“初”“从刀从衣”表示制衣服的起始难解多了。《说文解字》说“始”是“从女台声”，“台”表读音，经过几千年的演变，到今天完全变了音，走了调，这倒还好接受，就是“从女”简直不可思议。《说文解字》又注为“女之初也”，却也让人不知其详。

简介：该怎么办呢？助四郎很困惑。好不容易来到大坂．如今还有什么好犹豫的呢？虽然这么想，却总也下不了决心。心中所想之事太过荒诞无稽，正正经经地去谈恐怕谈不妥，甚至或许还会遭到怀疑被轰走。可这也没办法。想归想，这本就是十分难办的事。别说谈了，连该如何开口都不知道，真是叫人头疼。所以．助四郎才在店门口来回徘徊。
