一、冷軋板卷是鋼還是鐵
冷軋板卷是鋼材。
冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)板(ban)(ban)(ban)(ban)(ban)卷是普通碳(tan)素結構鋼(gang)(gang)冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)薄板(ban)(ban)(ban)(ban)(ban)的簡稱(cheng),又(you)稱(cheng)冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)薄板(ban)(ban)(ban)(ban)(ban),俗(su)稱(cheng)冷(leng)(leng)(leng)(leng)板(ban)(ban)(ban)(ban)(ban),有時被誤寫成冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)薄板(ban)(ban)(ban)(ban)(ban)。冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)板(ban)(ban)(ban)(ban)(ban)卷是厚度小(xiao)于4毫米的鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban),由普通碳(tan)素結構鋼(gang)(gang)熱軋(ya)(ya)(ya)(ya)鋼(gang)(gang)帶經進一步冷(leng)(leng)(leng)(leng)軋(ya)(ya)(ya)(ya)而(er)成。室溫(wen)軋(ya)(ya)(ya)(ya)制(zhi)不產(chan)生氧(yang)化皮,冷(leng)(leng)(leng)(leng)板(ban)(ban)(ban)(ban)(ban)表面質量好(hao),尺寸精度高。除退火處理(li)外,其力學性能和工藝(yi)性能均(jun)優于熱軋(ya)(ya)(ya)(ya)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban),在許(xu)多領域,尤其是家(jia)電制(zhi)造領域,已逐漸被用來替代熱軋(ya)(ya)(ya)(ya)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。
由于生產(chan)(chan)過程中沒有(you)加熱,所以(yi)沒有(you)熱軋中經(jing)常出(chu)現的(de)(de)麻點(dian)、鐵皮等(deng)缺陷,表面質量好,光(guang)潔(jie)度(du)(du)(du)高(gao)。而且冷軋產(chan)(chan)品尺寸精度(du)(du)(du)高(gao),產(chan)(chan)品的(de)(de)性(xing)能(neng)(neng)和結構(gou)可(ke)以(yi)滿足一些特(te)殊的(de)(de)應用要(yao)(yao)求(qiu),如電磁性(xing)能(neng)(neng)和深沖性(xing)能(neng)(neng)。規(gui)格:厚度(du)(du)(du)0.2-4毫米(mi)(mi),寬(kuan)度(du)(du)(du)600-2000毫米(mi)(mi),鋼(gang)(gang)板(ban)長度(du)(du)(du)1200-6000毫米(mi)(mi)商標(biao):Q195A-Q235A、Q195AF-Q235AF、q295a(b)-q345a(b);SPCC、SPCD、SPCE、ST12-15;DC01-06性(xing)能(neng)(neng):主要(yao)(yao)由低碳鋼(gang)(gang)制成,要(yao)(yao)求(qiu)具有(you)良好的(de)(de)冷彎和焊(han)接性(xing)能(neng)(neng)以(yi)及一定的(de)(de)沖壓性(xing)能(neng)(neng)。
二、冷軋板卷性能怎么樣
冷軋板卷和平板的差別就是裁剪包裝。冷軋板卷是熱軋卷板經過酸洗、冷軋得到的。可以說是冷軋板卷的一種冷軋板卷的退火態,經過酸洗、冷軋、罩式退火、平整、(精整)得到的。冷軋卷板的性能主要有以下優勢:
1、 更好的柔韌性
冷軋(ya)板卷在(zai)制造過(guo)程中的(de)細致處理和輕(qing)微冷變形(xing),使(shi)其具有更好的(de)柔韌性,即在(zai)低溫或高應變率下仍能(neng)保持原有性能(neng)。
2、更高的表面質量
冷軋板卷在經(jing)過加工處理時(shi),由于較少的變形和較少的殘留(liu)應力(li),表面(mian)質量比熱軋鋼板更(geng)為平滑。
3、更好的加工性能
由于冷軋板(ban)卷的加工(gong)硬化程度較輕,其具有更(geng)好的可(ke)加工(gong)性(xing)和成形能(neng)力,可(ke)適用于各種復雜結構的加工(gong)需求。
