硅鋼片簡介
硅鋼片又名電工鋼片,在鐵內參加少量硅能夠提高資料的電阻率并使磁老化明顯改進,資料的脆性添加,磁感應強度降低,因而硅的極限為4. 5%。硅鋼片主要用于工頻溝通電磁器材中,如變壓器、電機、互感器開關和繼電器的鐵心。我國習慣上把硅鋼片分為熱軋和冷軋硅鋼片,而現行國際上,大多按晶粒取向分為無取向和晶粒取向硅鋼片兩大類。
熱(re)軋(ya)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)是磁(ci)(ci)性(xing)無(wu)取(qu)向硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian),屬硅(gui)鐵合金。與(yu)冷(leng)軋(ya)片(pian)(pian)(pian)比較具(ju)有資料穩定性(xing)好、沖剪(jian)應(ying)(ying)(ying)(ying)力遠低于(yu)冷(leng)軋(ya)片(pian)(pian)(pian)、比重小(xiao)、同板差較大等(deng)特色(se)。而冷(leng)軋(ya)片(pian)(pian)(pian)屬低硅(gui)低碳(tan)(tan)合金,具(ju)有鐵損小(xiao)、磁(ci)(ci)感高(gao)(gao)、外表潤滑、厚度(du)均(jun)勻、同板差小(xiao)等(deng)特色(se)。電(dian)機(ji)(ji)鐵心(xin)采(cai)用(yong)(yong)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)替代碳(tan)(tan)鋼(gang)(gang)(gang)板和(he)純鐵,在(zai)歷史上是一個巨(ju)大的(de)提高(gao)(gao),低損耗的(de)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)改進(jin)了(le)電(dian)機(ji)(ji)功(gong)能,縮小(xiao)了(le)電(dian)機(ji)(ji)體(ti)積。現(xian)(xian)在(zai)用(yong)(yong)無(wu)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)替代硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)的(de)小(xiao)型(xing)電(dian)機(ji)(ji)鐵心(xin),是因(yin)為現(xian)(xian)代技術鍛煉的(de)無(wu)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian),不(bu)同于(yu)本來的(de)低碳(tan)(tan)鋼(gang)(gang)(gang)板,它不(bu)光具(ju)有高(gao)(gao)的(de)磁(ci)(ci)感應(ying)(ying)(ying)(ying)強度(du),并且(qie)具(ju)有與(yu)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)相近的(de)鐵耗。無(wu)論是冷(leng)軋(ya)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)仍是無(wu)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian),它的(de)磁(ci)(ci)感應(ying)(ying)(ying)(ying)強度(du)和(he)損耗對機(ji)(ji)械應(ying)(ying)(ying)(ying)力都十(shi).分靈敏(min),因(yin)而沖制后如何康(kang)復其原有導磁(ci)(ci)功(gong)能和(he)鐵損,是選用(yong)(yong)硅(gui)鋼(gang)(gang)(gang)片(pian)(pian)(pian)時應(ying)(ying)(ying)(ying)考慮處(chu)理(li)的(de)問題。
