鋼桶的優勢

1、經濟(ji)效益(yi)顯(xian)著(zhu) 減(jian)小(xiao)用(yong)材厚度(du)，鍍漆鋼桶，節(jie)約了原(yuan)材料，給(gei)企(qi)業(ye)帶來的經濟(ji)效益(yi)是(shi)顯(xian)著(zhu)的。

2、堆(dui)碼(ma)運輸(shu)方(fang)便，未縮頸(jing)(jing)(jing)(jing)的(de)桶底比較(jiao)(jiao)容(rong)(rong)易(yi)地套堆(dui)在縮頸(jing)(jing)(jing)(jing)后(hou)的(de)桶頂上(shang)，相對平穩(wen)安(an)全。反之，縮頸(jing)(jing)(jing)(jing)后(hou)的(de)桶底也比較(jiao)(jiao)容(rong)(rong)易(yi)地套堆(dui)在未縮頸(jing)(jing)(jing)(jing)的(de)桶頂上(shang)，但未縮頸(jing)(jing)(jing)(jing)的(de)桶頂的(de)強度并未增強，僅僅方(fang)便堆(dui)碼(ma)。錐形鋼桶的(de)空桶可以桶套桶的(de)運輸(shu)，增加了運量，降低了運輸(shu)成本(ben)，很受歡(huan)迎。但桶口(kou)不能縮頸(jing)(jing)(jing)(jing)，因而(er)桶口(kou)的(de)強度未增強，只(zhi)能縮桶底，否則，就失去了錐形桶的(de)優勢(shi)。

鋼桶卷(juan)封(feng)過程究竟能卷(juan)多(duo)少層(ceng)(ceng)？有人認為(wei)越多(duo)越多(duo)，這(zhe)話沒錯(cuo)！卷(juan)邊層(ceng)(ceng)數越多(duo)，強度越高(gao)，密封(feng)效果越好。然而是不是能夠實現(xian)十層(ceng)(ceng)、二十層(ceng)(ceng)的卷(juan)封(feng)呢？這(zhe)里我們且不說存在(zai)一個質量成(cheng)本 問題(ti)，實際上，這(zhe)是不能夠實現(xian)。

（1）鋼(gang)(gang)桶(tong)原材(cai)料(liao)(liao)的(de)(de)(de)(de)(de)限制(zhi)(zhi) 制(zhi)(zhi)作鋼(gang)(gang)桶(tong)，要求材(cai)料(liao)(liao)含碳量要低，塑性(xing)要好(hao)。因(yin)為(wei)(wei)這(zhe)樣加工性(xing)能(neng)好(hao)，焊接、沖壓、脹形都容易保證質量。但(dan)是(shi)卷(juan)(juan)邊(bian)就(jiu)不一樣了(le)，因(yin)為(wei)(wei)卷(juan)(juan)邊(bian)輥槽的(de)(de)(de)(de)(de)大小不可(ke)(ke)能(neng)隨著(zhu)卷(juan)(juan)邊(bian)過(guo)程(cheng)變化，卷(juan)(juan)邊(bian)力要通過(guo) 外圍(wei)的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)逐漸傳(chuan)遞(di)到卷(juan)(juan)邊(bian)中(zhong)(zhong)心去，才能(neng)把中(zhong)(zhong)心卷(juan)(juan)成(cheng)。而(er)材(cai)料(liao)(liao)的(de)(de)(de)(de)(de)塑性(xing)越好(hao)，力的(de)(de)(de)(de)(de)傳(chuan)遞(di)就(jiu)越困難。可(ke)(ke)以想象，如果鋼(gang)(gang)桶(tong)的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)采(cai)用(yong)彈(dan)簧鋼(gang)(gang)，徐州(zhou)鋼(gang)(gang)桶(tong)，像鐘表的(de)(de)(de)(de)(de)法條(tiao)一樣的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)，不要說(shuo)卷(juan)(juan)十層(ceng)，恐怕就(jiu)是(shi) 二十層(ceng)也很(hen)容易，因(yin)為(wei)(wei)它(ta)彈(dan)性(xing)和剛性(xing)好(hao)，20升鋼(gang)(gang)桶(tong)，通過(guo)外圍(wei)的(de)(de)(de)(de)(de)卷(juan)(juan)封(feng)(feng)(feng)力很(hen)容易傳(chuan)到中(zhong)(zhong)心。但(dan)這(zhe)是(shi)不可(ke)(ke)能(neng)的(de)(de)(de)(de)(de)，就(jiu)是(shi)因(yin)為(wei)(wei)這(zhe)種材(cai)料(liao)(liao)彈(dan)性(xing)好(hao)，所(suo)以在卷(juan)(juan)封(feng)(feng)(feng)結(jie)束后，卷(juan)(juan)封(feng)(feng)(feng)力消失的(de)(de)(de)(de)(de)情況下，很(hen)容易又反彈(dan)回原來的(de)(de)(de)(de)(de) 狀態，也就(jiu)是(shi)說(shuo)恢復到卷(juan)(juan)封(feng)(feng)(feng)開始(shi)的(de)(de)(de)(de)(de)樣子(zi)。這(zhe)樣顯(xian)然(ran)不是(shi)我們(men)(men)需要的(de)(de)(de)(de)(de)。所(suo)以，我們(men)(men)不可(ke)(ke)能(neng)選用(yong)高彈(dan)性(xing)的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)。就(jiu)目(mu)前全世(shi)界用(yong)來制(zhi)(zhi)作鋼(gang)(gang)桶(tong)的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)來看，我國(guo)(guo)的(de)(de)(de)(de)(de)材(cai)料(liao)(liao)剛性(xing)z大，所(suo)以質量也較難保 證。而(er)且(qie)卷(juan)(juan)邊(bian)層(ceng)數沒有(you)超(chao)過(guo)七(qi)層(ceng)的(de)(de)(de)(de)(de)。據國(guo)(guo)外有(you)關的(de)(de)(de)(de)(de)研究，鋼(gang)(gang)桶(tong)卷(juan)(juan)邊(bian)層(ceng)數不會超(chao)過(guo)七(qi)層(ceng)，顯(xian)然(ran)卷(juan)(juan)封(feng)(feng)(feng)力傳(chuan)送不到那么遠。
