style="text-indent:25px">配料時要在企業(yè)內(nèi)部標(biāo)準(zhǔn)規(guī)定的化學(xué)成分范圍內(nèi)確定其配料值(計算成分)。配料值一般情況下是按內(nèi)標(biāo)的中限選取;但對于易燒損的元素宜按中限偏上選取,以保證該元素的含量能落在內(nèi)標(biāo)成分的范圍內(nèi);對于不易燒損而又稀貴的元素宜按中限偏下選取,這樣可以降低成本。對于易引起鑄造裂紋和形成化合物一次晶的某些元素,確定配料值時要將其控制在較佳范圍內(nèi),以便穩(wěn)定鑄造工藝,防止鑄造缺陷。工藝時間主要由生產(chǎn)工藝和投料量所決定，生產(chǎn)工藝越復(fù)雜，工序數(shù)量越多，工藝時間就越長；一次裝爐投料量越大，各工序所耗時間就越多，工藝時間也就越長。由于各種金屬在鋁合金棒材熔體中都存在一定的燒損，工藝時間越長合金熔體中的合金燒損量就越多。因此在配料時需充分考慮工藝時間，摸索出不同工藝時間下各種合金元素的燒損率才能準(zhǔn)確的進行配料。一次配料準(zhǔn)確也能很大程度上的節(jié)約工藝時間，降低生產(chǎn)成本。湖州7075鋁棒</p></p><br
