简介：随着我国经济的快速发展,锻造行业已进入工业发展的高速期,并越来越显示出其桥梁与基础的重要作用。近几年,随着锻造工业的迅速发展,各种先进的锻压设备、锻造工艺迅速得到普及应用,使我国锻造工业迎来一个质的飞跃。但是,锻造行业还存在一个关键问题没得到有效解决,并影响和制约着锻造工业的高速发展,那就是环保问题。锻造环境污染问题的源头就是锻造常用的石墨系列脱模剂,其污染程度众所周知,可谓万恶之源。

简介：洛阳市冠华精锻齿轮总厂（以下简称“冠华”）是生产汽车农用车及拖拉机用差速器直齿锥齿轮的专业厂家．已有十多年建厂历史。建厂之初，精锻齿轮因具有节能、节材、结实耐用而逐渐代替传统的切削齿轮，但随着精锻齿轮行业生产厂家的不断增多．特别是近两年南方个体私营企业涉足精锻齿轮领域，采取无序的价格竞争．使得精锻齿轮行业的利润跌入低谷．有些农机齿轮仅是维持成本．几乎无利润可言。

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。
