2014年5月19日至5月22日,在北京舉行第十二屆中國國際鑄造博覽會在國內外鑄造界引起了巨大的反響。“智能、綠色、高端”成了該展會的關鍵詞。尤其展出的那些對我國國民經濟各領域中各類機械裝備有重大影響的、高質量、高性能、高水平,被稱之為“高端”的鑄件引起了參觀者的高度關注。作者有幸主持了鑄鐵件金巴黎彩票生產技術論壇專場討論會。會場氣氛十分熱烈,參會者也十分踴躍,不少人都一直站著聽完報告。報告后,中國機械科學院的曾藝成研究員與河北工業大學的錢立教授也作了精彩的評論與發言。他們認為:任何企業在任何時候,都應該把提高產品的品質與質量放在首要位置,而質量的穩定性與一致性是質量管理中的重中之重。

我國鑄造業正處于從生產大國到鑄造強國的關鍵時期。產品的升級換代,產品結構的提升與轉型對每一個鑄造廠都是一個挑戰。在鑄造生產技術討論專場報告的四個企業給予了我們許多重要的啟示。

一、高端鑄件的一些特點

1、這類鑄件所承載的設備在國民經濟中地位顯要,而該類鑄件的質量優劣又對其組成設備的安全、質量、壽命有著決定性的影響。金巴黎彩票即該鑄件所承載的作用重大,生產該類鑄件的企業責任重大。以論壇會上四個企業生產的鑄件為例:如對質量問題實行“零容忍”的高速列車上的轉向架軸箱;要求在風電機組上,使用20年不更換的風電鑄件;具有高碳當量、高強度、高剛度、低應力的精密數控機床的機床鑄件;具有高疲勞強度要求的QT800-5材質的汽車支架。

以上四例表明,高端鑄件質量優劣的影響力及重要度,遠勝過一般鑄件。生產高端鑄件的鑄造廠及其生產者將對國家、社會、人民負有重大的責任。【未完待續】
