一、電解鋁耗電量如何

電(dian)解(jie)鋁行業屬于高耗(hao)能企業，生(sheng)產一噸電(dian)解(jie)鋁綜(zong)合電(dian)耗(hao)13500度電(dian)，電(dian)解(jie)鋁對于電(dian)量需求十分高，因為電(dian)解(jie)鋁的過程是冰晶石和氧(yang)化鋁在900多度的高溫中進行電(dian)解(jie)。

以2020年為例：2020年中國電解鋁產(chan)量(liang)為3731.7萬噸(dun)，占全世界的(de)57.18%，僅(jin)電(dian)解鋁(lv)一項耗電(dian)總量(liang)就達到(dao)約4851.21億(yi)千(qian)瓦時(shi)。而(er)2020年(nian)中國全社會用(yong)電(dian)量(liang)也只(zhi)有75110億(yi)千(qian)瓦時(shi)，只(zhi)是(shi)電(dian)解鋁(lv)就約占全國用(yong)電(dian)量(liang)的(de)6.46%。

二、電解鋁耗電量怎么算

電(dian)解鋁的耗電(dian)量是根據電(dian)流、時間、電(dian)壓和電(dian)解質濃(nong)度來計算的，具體(ti)方(fang)法如下(xia)：

1、確定電流大小

鋁制品供應總量、電解鋁的(de)用(yong)途、原材(cai)料成本、發電機功率(lv)因(yin)數(shu)等眾多因(yin)素決定了(le)電解鋁過程(cheng)中的(de)電流(liu)大小。電流(liu)的(de)單位為安培，電流(liu)越(yue)大，耗電量就越(yue)大。

2、確定電解質濃度

電(dian)(dian)(dian)解質(zhi)指在電(dian)(dian)(dian)解過程(cheng)中起著導電(dian)(dian)(dian)和溶解氧化鋁的(de)作用的(de)化學物質(zhi)。電(dian)(dian)(dian)解質(zhi)的(de)濃(nong)度會影響電(dian)(dian)(dian)解過程(cheng)的(de)速率和耗電(dian)(dian)(dian)量。一般(ban)來說，濃(nong)度越大(da)，電(dian)(dian)(dian)源電(dian)(dian)(dian)壓就(jiu)越高，而電(dian)(dian)(dian)流就(jiu)越小，反(fan)之(zhi)亦然。

3、確定電壓大小

電(dian)(dian)(dian)(dian)壓指電(dian)(dian)(dian)(dian)解過程中(zhong)使用的(de)(de)(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)解鋁(lv)過程中(zhong)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓大(da)(da)小(xiao)會(hui)影(ying)響(xiang)電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)大(da)(da)小(xiao)和耗電(dian)(dian)(dian)(dian)量。電(dian)(dian)(dian)(dian)解鋁(lv)過程中(zhong)所(suo)用的(de)(de)(de)電(dian)(dian)(dian)(dian)源的(de)(de)(de)電(dian)(dian)(dian)(dian)壓通常(chang)與電(dian)(dian)(dian)(dian)解質的(de)(de)(de)濃度和電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)大(da)(da)小(xiao)有(you)關。

4、計算時間

時間(jian)是指電解(jie)鋁過程(cheng)中電流通過的時間(jian)。時間(jian)的單位通常(chang)為秒、分鐘或小時。

5、計算電解鋁的耗電量

電(dian)解鋁(lv)(lv)耗電(dian)量的計算公式為：電(dian)解鋁(lv)(lv)的耗電(dian)量（度(du)）=電(dian)功（千瓦(wa)時(shi)(shi)）x時(shi)(shi)間(jian)（小時(shi)(shi)）=電(dian)流(liu)（安培）x電(dian)壓（伏特）x時(shi)(shi)間(jian)（小時(shi)(shi)）/1000。
