冷軋板的用途

2019-03-18 10:05:23

冷軋板帶用途很廣,如汽車制造、電氣產品、機車車輛、航空、精密儀表、食品罐頭等。   冷軋薄鋼板是普通碳素結構鋼冷軋板的簡稱,也稱冷軋板,俗稱冷板,有時會被誤寫成冷扎板。冷板是由普通碳素結構鋼熱軋鋼帶,經過進一步冷軋制成厚度小于4mm的鋼板。由于在常溫下軋制,不產生氧化鐵皮,因此,冷板表面質量好,尺寸精度高,再加之退火處理,其機械性能和工藝性能都優于熱軋薄鋼板,在許多領域里,特別是家電制造領域,已逐漸用它取代熱軋薄鋼板。   適用牌號:Q195、Q215、Q235、Q275;SPCC(日本牌號);ST12(德國牌號)   符號:冷軋板的用途   1、Q—普通碳素結構鋼屈服點(極限)的代號,它是“屈”的第一個漢語拼音字母的大小寫;195、215、235、255、275—分別表示它們屈服點(極限)的數值,單位:兆帕MPa(N/mm2);由于Q235鋼的強度、塑性、韌性和焊接性等綜合機械性能在普通碳素結構鋼中屬最了,能較好地滿足一般的使用要求,所以應用范圍十分廣泛。   2、S-鋼(Steel)、P-板(Plate)、C-冷軋(cold)、第四位C-普通級(common)。   3、ST-鋼(Steel)、12-普通級冷軋薄鋼板、    標記:尺寸精度—尺寸—鋼板品種標準   冷軋鋼板:鋼號—技術條件標準   標記示例:B-0.57501500-GB708-88;鋼板、標準號Q/BQB402,牌號SPCC,熱處理狀態退火+平整(S),表央加工狀態為麻面D,表面質量為FB級的切邊(切邊EC,不切邊EM)鋼板、厚度0.5mm,B級精度,寬度1000mm,A級精度,長度2000mm,A級精度,不平度精度為PF.A,則標記為:鋼板ECQ/BQB 402-SPCC-SD-FB/(0.51000A2000A-PF.A);   冷軋鋼板:Q225-GB912-89   主要產地有:寶鋼、鞍鋼、本鋼、武鋼、邯鋼、包鋼、唐鋼、漣鋼、濟鋼等   冷軋普通薄鋼板 :由普通碳素結構鋼或低合金結構鋼冷軋制成。冷軋板表面質量較好。具有良好的沖壓性能。對其要求要保證冷彎和杯試驗合格,常用于汽車等行業和鍍層板的原料。   冷軋優質薄鋼板:主要包括各種優質鋼冷軋薄板,最常用的是碳素結構鋼板,尤其是深沖壓用冷軋薄鋼板,是由低碳優質鋼08Al冷軋的薄板,鋼板按表面質量分為三組;Ⅰ、Ⅱ、Ⅲ,分別表示特別高級、高級、較高的精整表面,按拉延級別分為ZF、HF、F級(代表用于沖制拉延最復雜、很復雜、復雜的零件),根據鋼板厚度允許偏差,又分為A、B兩級精度、廣泛用于汽車拖拉機工業。   冷軋鋼板,表面光潔,加工優良,用于汽車、冰箱、洗衣機等家電,以及產業設備、各種建筑材料。隨著經濟發展,冷軋鋼板已被稱為現代社會的必須材料。 冷軋產品的分類: 熱軋酸洗、軋硬卷、普通冷軋、鍍鋅(電鍍鋅、耐指紋、熱鍍鋅)、鍍鋁鋅、電鍍錫、彩涂、電工鋼(矽鋼片)等。   1、熱軋酸洗:  2、軋 硬 卷:在常溫下,對熱軋酸洗卷進行連續軋制?! ‘a品特點:因為沒有經過退火處理,其硬度很高(HRB大于90),機械加工性能極差,只能進行簡單的有方向性的小于90度的折彎加工(垂直于卷取方向)。

冷軋鍍鋅

冷軋是在室溫條件下將鋼板進一步軋薄至為目標厚度的鋼板。和熱軋鋼板比較,冷軋鋼板厚度更加精確,而且表面光滑、漂亮,同時還具有各種優越的機械性能,特別是加工性能方面。因為冷軋原卷比較脆硬,不太適合加工,所以通常情況下冷軋鋼板要求經過退火、酸洗及表面平整之后才交給客戶。冷軋最小厚度是0.1--8.0MM以下,大部份工廠如保定普瑞鋼材冷軋鋼板厚度是4.5MM以下;最少厚度、寬度是根據各工廠的設備能力和 市場 需求而決定。冷軋的優缺點:優點:成型速度快、 產量 高,且不損傷涂層,可以做成多種多樣的截面形式,以適應使用條件的需要;冷軋可以使鋼材產生很大的塑性變形,從而提高了鋼材的屈服點。缺點: 1.雖然成型過程中沒有經過熱態塑性壓縮,但截面內仍然存在殘余應力,對鋼材整體和局部屈曲的特性必然產生影響;2.冷軋型鋼樣式一般為開口截面,使得截面的自由扭轉剛度較低。在受彎時容易出現扭轉,受壓時容易出現彎扭屈曲,抗扭性能較差;3.冷軋成型鋼壁厚較小,在板件銜接的轉角處又沒有加厚,承受局部性的集中荷載的能力弱。鍍鋅是在裝有鍍件、玻璃球、鋅粉、水和促進劑的旋轉滾桶內,作為沖擊介質的玻璃球隨著滾桶轉動,與鍍件表面發生摩擦和錘擊產生機械物理能量,在化學促進劑的作用下,將鍍涂的鋅粉“冷焊”到鍍件表面上,形成光滑、均勻和細致的具有一定厚度的鍍層。鍍鋅分為熱鍍鋅和電鍍鋅兩種。熱鍍鋅也叫熱浸鍍鋅和熱浸鋅,是一種有效的 金屬 防腐方式,主要用于各 行業 的 金屬 結構設施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中,使鋼構件表面附著鋅層,從而起到防腐的目的。電鍍鋅,是利用電解設備將管件經過除油、酸洗、后放入成分為鋅鹽的溶液中,并連接電解設備的負極,在管件的對面放置鋅版,連接在電解設備的正極接通電源,利用電流從正極向負極的定向移動就會在管件上沉積一層鋅,冷鍍管件是先加工后鍍鋅。

冷軋:用熱軋鋼卷為原料,經酸洗去除氧化皮后進行冷連軋,其成品為軋硬卷,由于連續冷變形引起的冷作硬化使軋硬卷的強度、硬度上升、韌塑指標下降,因此沖壓性能將惡化,只能用于簡單變形的零件。軋硬卷可作為熱鍍鋅廠的原料,因為熱鍍鋅機組均設置有退火線。軋硬卷重一般在6~13.5噸,鋼卷在常溫下,對熱軋酸洗卷進行連續軋制。內徑為610mm。產品特點因為沒有經過退火處理,其硬度很高(HRB大于90),機械加工性能極差,只能進行簡單的有方向性的小于90度的折彎加工(垂直于卷取方向)。簡單來說,冷軋,是在熱軟板扎的基礎上加工軋制出來的,一般來講是熱軋→酸洗→冷軋這樣的加工過程。冷軋是在常溫狀態下由熱軋板加工而成,雖然在加工過程因為軋制也會使鋼板升溫,盡管如此還是叫冷軋。由熱軋經過連續冷變形而成的冷軋,機械性能比較差,硬度太高,必須經過退火才能恢復其機械性能,沒有退火的叫軋硬卷。軋硬卷一般是用來做無需折彎,拉伸的產品,1.0以下厚度軋硬的運氣好的兩邊或者四邊折彎?;瘜W成分(Wt%)牌號CSiMnPSCuSPCC0.02~0.08≤0.100.15~0.30≤0.045≤0.050≤0.050Q1950.06~0.12≤0.300.25~0.50≤0.045≤0.050≤0.050Q235-B0.12~0.20≤0.300.30~0.70≤0.045≤0.050≤0.050制作工序冷軋通常采用眾軋的方式。冷軋生產的工序一般包括原料準備、酸洗、軋制、脫脂、退火(熱處理)、精整等。冷軋以熱軋產品為原料,冷軋前原料要先除磷,以保證冷軋產品的表面潔凈。軋制是使材料變形的主要工序。脫脂的目的在于去除軋制時附在軋材上的潤滑油脂,以免退火時污染鋼材表面,對不銹鋼也為防止增碳。退火包括中間退火和成品熱處理,中間退火是通過再結晶消除冷變形時產生的加工硬化,以恢復材料的塑性及降低金屬的變形抗力。成品熱處理的目的除了通過再結晶消除硬化外。還在于根據產品的技術要求以獲得所需要的組織(如各種織構等)和產品性能(如深沖、電磁性能等)。精整包括檢查、剪切、矯直(平整)、打印、分類包裝等內容。冷軋產品有很高的包裝要求,以防止產品在運輸過程中表面被刮傷。除上述工序外在生產一些特殊產品時還有各自的特殊工序。如軋制硅鋼板時,在冷軋前要進行脫碳退火,軋后要進行涂膜、高溫退火、拉伸矯直(見張力矯直)與回火等。用于冷軋帶剛的軋機有二輥軋機、四輥軋機和多輥軋機。應用最多的是四輥軋機。軋制更薄的產品則要采用多輥軋機。多輥軋機的種類很多,如六輥軋機、偏八輥軋機,十二輥軋機,二十輥軋機等(見軋機)。隨著對板形要求的提高,發展了許多改進板形的技術,如彎輥技術、竄輥技術和交叉軋輥技術等。冷軋帶鋼軋機按機架排列可分為單機可逆或不可逆式與多機連續式兩類。前者適用于多品種、少批量或合金鋼產品比例大的情況。它投資低、建廠快,但產量低,金屬消耗較大。多機架連續軋制適合于產品品種較單一或者變動不大的情況,它有生產效率高、產量大的優點,但投資較大。與熱軋帶鋼(見熱連軋寬帶鋼生產工藝、熱軋窄帶鋼生產)相比,冷軋帶鋼(見冷板扎帶生產)的軋制工藝有以下特點:(1)采用工藝潤滑和冷卻,以降低軋制時的變形抗力和冷卻軋輥;(2)采用大張力軋制,以降低變形抗力和保持軋制過程的穩定。采用的平均單位張力值為材料屈服強度的10%~60%,一般不超過50%;(3)采用多軋程軋制。由于冷軋使材料產生加工硬化,當總變形量達到60%~80%時,繼續變形就變得很困難。為此要進行中間退火,使材料軟化后軋制得以繼續進行。為了得到要求的薄帶鋼,這樣的中間退火可能要進行多次。兩次中間退火之間的軋制稱為一個軋程。冷軋帶鋼的退火在有保護氣體的連續式退火爐或罩式退火爐中進行(見冷軋板帶退火)。冷軋帶鋼的最小厚度目前可達到0.05mm,冷軋箔材可達到0.001mm。

冷軋知識介紹

冷軋:用熱軋鋼卷為原料,經酸洗去除氧化皮后進行冷連軋,其成品為軋硬卷,由于連續冷變形引起的冷作硬化使軋硬卷的強度、硬度上升、韌塑指標下降,因此沖壓性能將惡化,只能用于簡單變形的零件。軋硬卷可作為熱鍍鋅廠的原料,因為熱鍍鋅機組均設置有退火線。軋硬卷重一般在20-40噸,鋼卷在常溫下,對熱軋酸洗卷進行連續軋制。內徑為610mm?!   ‘a品特點:因為沒有經過退火處理,其硬度很高(HRB大于90),機械加工性能極差,只能進行簡單的有方向性的小于90度的折彎加工(垂直于卷取方向)?!   『唵蝸碚f,冷軋,是在熱軋板卷的基礎上加工軋制出來的,一般來講是熱軋---酸洗---冷軋這樣的加工過程?!   ±滠埵窃诔貭顟B下由熱軋板加工而成,雖然在加工過程因為軋制也會使鋼板升溫,盡管如此還是叫冷軋。由于熱軋經過連續冷變型而成的冷軋,在機械性能比較差,硬度太高。必須經過退火才能恢復其機械性能,沒有退火的叫軋硬卷。軋硬卷一般是用來做無需折彎,拉伸的產品,1.0以下厚度軋硬的運氣好的兩邊或者四邊折彎?!   ±滠堃话愣紩涍^退火處理。

冷軋鋼板標準

2019-03-18 08:36:58

冷軋薄鋼板,簡稱冷軋鋼板、冷軋薄板、冷軋板、冷板等。它還包括不銹鋼板、彈簧鋼板、硬鋼片、鍍鋅板、鍍錫板、鍍鋁板等。冷軋薄鋼帶,簡稱冷軋鋼帶、冷軋帶鋼、鋼帶、帶鋼、薄鋼帶、冷軋卷等。還包括不銹鋼帶、鍍鋅鋼帶、鍍錫鋼帶等。 冷軋鋼板標準 冷軋薄鋼板、鋼帶(以下簡稱冷軋薄板)主要用于零件的沖壓加工,而冷軋薄板的力學性能十分重要,它直接關系到板材的沖壓性能。冷軋薄板是以不同的熱處理狀態分級的,不同硬度的材料,用于不同的加工方法,國家標準GB/T 13237-1991《優質碳素結構鋼冷軋薄鋼板和鋼帶》將冷軋薄板大致分為三級,P級用于普通沖壓,S級用于深度沖壓,Z級用于最深度沖壓。中國冶金標準YB/T 5059-1993《低碳鋼冷軋鋼帶》將薄鋼板按硬度分為五級,即:TR(特級)、R(軟)、BR(半軟)、DY(低硬)和Y(冷硬)。其實通過一定的冷軋變形程度和冷軋后熱處理的恰當配合,可以在廣泛的范圍內滿足用戶關于材料力學性能方面的要求。冷軋薄板根據用戶加工上的要求可以分成更多的級別。例如:日本工業標準JIS G3141-1996《冷軋碳素鋼鋼板和鋼帶》的分類除分為一般用(spcc)、沖壓用(spcd)和深沖壓用(spce)三類外,還細分為退火、標準調質、1/8硬、1/4硬、1/2硬、全硬等級別。 在冷軋薄板力學性能的檢測方面,一些標準只規定了拉伸試驗,另一些標準除拉伸試驗外還規定了硬度試驗。 中國標準GB/T 13237-1991就只規定了拉伸試驗,技術要求冷軋鋼板標準如表一所示:牌號 抗拉強度/MPa伸長率不小于拉延級別Z-S和PZSP08F275~365275~38034323008,08Al,10F275~390275~41032302810295~410295~43030392815F315~430315~45029282715335~450335~47027262520355~490335~50026252425——390~540——242330——440~590——222135——490~635——201940——510~650————1845——530~680————1650——540~715————14 日本標準JIS G3141-1996《冷軋碳素鋼鋼板和鋼帶》(該標準中包含了冷軋薄鋼板和鋼帶)規定了拉伸試驗,也規定了硬度試驗,該標準的力學性能要求如下:表二:標準調質和退火的鋼板、鋼帶的拉伸試驗質牌號抗拉強度/MPa 不小于 伸長率/%不小于試樣按以下公稱厚度/mm>=0.250.250.400.601.01.6>=2.5SPCC SPCD SPCE(270) 270 270(32) 34 36(34) 36 3836 38 40  37 39 41    (38) 40 42  39 41 435號試樣軋制方向 表三:標準調質和退火的鋼板、鋼帶的硬度值。調質區分符號 硬度最大HRBHV退火A57105標準調質S65115 注:厚度小于0.6mm的鋼板和鋼帶,原則上不進行拉伸試驗。 表四:1/8硬、1/4硬、1/2硬和全硬材料的拉伸試驗值。調質區分 符號 抗拉強度/MPa伸長率/%最小試樣1/8硬8294~410255號試樣軋制方向1/4硬4370~490101/2硬2440~590——硬1>=550—— ????表五:1/8硬、1/4硬、1/2硬和全硬狀態的硬度值。調質區分符號HRBHV1/8硬 1/4硬8450~7165~8095~130 115~1501/2硬 硬2174~89 ≥85135~185 ≥170注:HRB和HV,僅選用其中之一。英國標準BS 1449/1.9-1991《厚板、薄板和鋼帶第一部分:碳素鋼和碳錳鋼厚板、薄板和鋼帶具有成形性能的冷軋窄鋼帶技術條件》對冷軋板分級為CS1(鋁鎮靜穩定化超深沖)、CS2(超深沖)、CS3(深沖)、CS4(折邊)、CS15(商品級)。這項標準的力學性能要求如表六所示: 表六:鋼材交貨時的力學性能軋制狀態和級別退火(A)或平整冷軋(SP)狀態硬度HV1)2)最大屈服強度Re1)/MPa最小抗拉強度Rm1)/MPa最小伸長率A1)/%最小彎心直徑1)(180°彎曲)原始標距LO50mm80mmCS1A9514027038(36)0aSP10514027036(34)0aCS2A9514027036(34)0a?SP10014027036(34)0aCS3A100(140)(280)(34)(32)0aSP110(140)(280)(34)(32)0aCS4A105(140)(280)——0aSP115(140)(280)——0a 注:1)窄鋼帶交貨應符合,或者硬度和彎曲試驗,或者拉伸和彎曲試驗,但硬度和拉伸試驗不應同時進行。 ????2)對于SP(平整冷軋)狀態,與鍍層精整(PL)或鏡面光潔度(MF),或以“無拉伸痕”交貨的鋼材組合,最大硬度可以提高5個HV或抗拉強度可以提高20MPa。 ????3)牌號CS2、CS3和CS4的硬度值僅適用于沸騰鋼。 如上所述冷軋薄板的力學性能可以通過拉伸試驗來檢測,也可以通過硬度試驗來檢測。由于硬度試驗設備簡單、易于掌握,試驗效率高,并且金屬硬度與強度之間有一定的對應關系,所以硬度檢測是確定材料力學性能的更方便的方法。冷軋薄板的硬度檢測可以用于冷軋板生產過程的質量控制,更適于生產沖壓產品的廠家對原材料進行力學性能的復檢。 日本工業標準JIS G3141-1996規定的硬度試驗是洛氏硬度HRB和維氏硬度HV。維氏硬度試驗可用于冷軋薄板,但洛氏硬度HRB卻不適用于測試薄板材料。因為當板材厚度小于2mm時,測試HRB硬度可能會因為發生“測砧效應”而使測量的硬度值失準。對于薄板材料,可以測試表面洛氏硬度HRN或HRT,然后換算成HRB或HV硬度。冷軋鋼板標準生產了一種便攜式表面洛氏硬度計,它非常適合測試薄板和鋼帶材料,它可以在生產現場、銷售現場或材料倉庫快速進行冷軋薄板材料的洛氏硬度檢測,完成一次測量僅需要10秒鐘時間,檢測的板材厚度范圍為0.05-50mm。這種儀器可以用在冷軋薄板帶的生產線上,對產品的熱處理效果進行在線的質量控制。這種儀器更適用于沖壓產品的生產廠家??梢杂盟鼘徣氲陌宀挠捕冗M行復檢,可以攜帶它去鋼材市場選購材料,也可以利用它對自己廠生產的沖壓產品進行硬度檢測。 這種儀器如果配上一個支承座,還可以放到辦公桌上使用??梢詫Τ膳某善坊虬氤善饭ぜ鲋鸺z測。它的測試精度與臺式洛氏硬度計相同。 目前冷軋薄帶材料正在向超薄方向發展,據報道,上海寶鋼已扎制出厚度為0.08mm的冷軋薄板帶材。采用本所生產的PHR-1S型表面洛氏硬度計,配一個金剛點砧座,就可測試薄至0.05mm冷軋薄板帶材料的硬度。 這種應用完全可以取代維氏硬度計,使冷軋薄板材料的力學性能檢測實現快速、簡便、經濟。

冷軋鍍鋅板

2017-06-06 17:50:07

冷軋鍍鋅板,是一種鍍鋅鋼板。鋼板按軋制分為熱軋和冷軋兩種。冷軋板是平板狀的,矩形的,可直接軋制而成的。冷軋是在室溫條件下將鋼板進一步軋薄至為目標厚度的鋼板。和熱軋鋼板比較,冷軋鋼板厚度更加精確,而且表面光滑、漂亮,同時還具有各種優越的機械性能,特別是加工性能方面。因為冷軋原卷比較脆硬,不太適合加工,所以通常情況下冷軋鋼板要求經過退火、酸洗及表面平整之后才交給客戶。冷軋最小厚度是0.1--8.0MM以下,大部份工廠如保定普瑞鋼材冷軋鋼板厚度是4.5MM以下;最少厚度、寬度是根據各工廠的設備能力和 市場 需求而決定。冷軋和熱軋的區別: 1、冷軋成型鋼允許截面出現局部屈曲,從而可以充分利用桿件屈曲后的承載力;而熱軋型鋼不允許截面發生局部屈曲。2、熱軋型鋼和冷軋型鋼殘余應力產生的原因不同,所以截面上的分布也有很大差異。冷彎薄壁型鋼截面上的殘余應力分布是彎曲型的,而熱扎型鋼或焊接型鋼截面上殘余應力分布是薄膜型。3、熱軋型鋼的自由扭轉剛度比冷軋型鋼高,所以熱軋型鋼的抗扭性能要優于冷軋型鋼。冷軋的優缺點:優點:成型速度快、 產量 高,且不損傷涂層,可以做成多種多樣的截面形式,以適應使用條件的需要;冷軋可以使鋼材產生很大的塑性變形,從而提高了鋼材的屈服點。缺點: 1.雖然成型過程中沒有經過熱態塑性壓縮,但截面內仍然存在殘余應力,對鋼材整體和局部屈曲的特性必然產生影響;2.冷軋型鋼樣式一般為開口截面,使得截面的自由扭轉剛度較低。在受彎時容易出現扭轉,受壓時容易出現彎扭屈曲,抗扭性能較差;3.冷軋成型鋼壁厚較小,在板件銜接的轉角處又沒有加厚,承受局部性的集中荷載的能力弱。冷軋鍍鋅板用于汽車、冰箱、洗衣機等家電,以及 產業 設備、各種建筑材料。

冷軋鋼板的密度

2019-03-18 08:36:58

冷軋鋼板就是經過冷軋生產的鋼板。冷軋是在室溫條件下將No.1鋼板進一步軋薄至為目標厚度的鋼板。和熱軋鋼板比較,冷軋鋼板厚度更加精確,而且表面光滑、漂亮,同時還具有各種優越的機械性能,特別是加工性能方面。因為冷軋原卷比較脆硬,冷軋鋼板的密度不太適合加工,所以通常情況下冷軋鋼板要求經過退火、酸洗及表面平整之后才交給客戶。冷軋最大厚度是0.1--8.0MM以下,如大部份工廠冷軋鋼板厚度是4.5MM以下;最少厚度、寬度是根據各工廠的設備能力和市場需求而決定。冷軋鋼板的密度:熱軋鋼板含碳量可比冷軋鋼板略高些。在成份相持不大的情況下密度是一樣的。但如果成份相差懸殊,如不銹鋼不論冷軋、熱軋密度都在7.9g/cm3左右。具體還要看成份,熱軋只是延展性更好,鋼材同樣受到壓力作用

電工用冷軋硅鋼薄板

2018-05-10 17:56:11

(二)電工用冷軋硅鋼薄板(GB2521-88)    用含硅0.8%-4.8%的電工硅鋼為材質,經冷軋而成。    冷軋硅鋼片分晶粒無取向和晶粒取向兩種鋼帶。冷軋電工鋼帶具有表面平整、厚度均勻、疊裝系數高、沖片性好等特點,且比熱軋電工鋼帶磁感高、鐵損低。用冷帶代替熱軋帶制造電機或變壓器,其重量和體積可減少0%-25%。若用冷軋取向帶,性能更佳,用它代替熱軋帶或低檔次冷軋帶,可減少變壓器電能消耗量45%-50%,且變壓器工作性能更可靠。    用于制造電機和變壓器。通常,晶粒無取向冷軋帶用作電機或焊接變壓器等的狀態;晶粒取向冷軋帶用作電源變壓器、脈沖變壓器和磁放大器等的鐵芯。    鋼板規格尺寸:厚度為0.35、0.50、0.65mm,寬度為800-1000mm,長度為≤2.0m。
