(2)冷軋模具鋼的選用冷軋模具鋼的主系列是高硬冷作類,主要用于要求高抗壓和耐磨為主的模具,,硬度高于hrc60-62,。對(duì)于要求耐沖擊、韌性高的模具,,硬度低于hrc60- 62,,主要用s類和部份a類和普通的調(diào)質(zhì)鋼,、彈簧鋼、熱作模具或基體鋼,。對(duì)于大型沖壓模,,如汽車外型沖壓件,主要用鑄鐵類,。簡易或壽命數(shù)量少的用鋅基合金或高分子復(fù)合材料,。塑料模具鋼美國是早在工具鋼中列出塑料模具---鋼的,以p來表示為主,,共分為五類,。◆ 滲碳型塑料模具鋼:p1,,p2,,p3,p4,,p5,,p6。這類鋼含碳量很低,,主要是美國早期及用擠壓成型制模法,,要求冷塑性好,有高的擠壓性能,,成型后表面滲碳淬火提高表面硬度,,使用---。芯部---碳可使淬火時(shí)變形量,�,!粽{(diào)質(zhì)型塑料模具:p20,p21,。塑料模具中p20的用量很大,,已成為主體,大多數(shù)在預(yù)硬狀態(tài)時(shí)使用,。
(六)鋼鐵行業(yè)固定資產(chǎn)投資增幅明顯回落,。2013年1-6月,鋼鐵行業(yè)固定資產(chǎn)投資3035億元,,同比增長4.3%,,其中黑色金屬冶煉及壓延投資2356億元,同比增長3.3%,,比2012年同期回落6.1個(gè)百分點(diǎn);黑色金屬礦采選投資679億元,,同比增長7.8%,增速大幅回落15個(gè)百分點(diǎn)。
