熱(re)鍍鋅生產(chan)(chan)發展(zhan)(zhan)(zhan)一直(zhi)處于滯后(hou)狀(zhuang)態。20世(shi)紀50年(nian)代(dai)到60年(nian)代(dai)陸續建(jian)(jian)成了13條單張鋼板熔劑法熱(re)鍍鋅機(ji)組，能力為10萬t/a，但因產(chan)(chan)量低、成本高、質量差、污染環境(jing)、經濟(ji)效益差等缺(que)陷已先后(hou)停(ting)、轉產(chan)(chan)。從20世(shi)紀70年(nian)代(dai)末，我國才開始建(jian)(jian)造(zao)大(da)型寬帶熱(re)鍍鋅機(ji)組。熱(re)鍍鋅帶鋼在我國市(shi)場一直(zhi)是緊缺(que)品種。從20世(shi)紀90年(nian)代(dai)中期以來(lai)，每(mei)年(nian)都要從國外進口80-100萬t左右。隨著國內(nei)經濟(ji)的發展(zhan)(zhan)(zhan)，尤其(qi)是汽車、家電及(ji)建(jian)(jian)筑(zhu)業的發展(zhan)(zhan)(zhan)，對鍍鋅帶鋼的需(xu)求量也大(da)大(da)增加。

熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)和電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)在鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量上有很(hen)(hen)(hen)大(da)(da)(da)(da)的(de)差(cha)別(bie)，就(jiu)像山(shan)東彩涂卷）。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量不(bu)可能太小，一(yi)般(ban)較(jiao)(jiao)小為雙面50～60g／m2，較(jiao)(jiao)大(da)(da)(da)(da)可達600g／m2。電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)可以(yi)很(hen)(hen)(hen)薄(bo)，較(jiao)(jiao)小達15g／m2，但要求(qiu)鍍(du)(du)(du)(du)層(ceng)較(jiao)(jiao)厚的(de)話則生產(chan)線速度(du)很(hen)(hen)(hen)慢，不(bu)適(shi)應(ying)現代化(hua)機組的(de)工藝特點，一(yi)般(ban)較(jiao)(jiao)大(da)(da)(da)(da)為lO0g／m2左(zuo)右。正因為如此，電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)的(de)生產(chan)受到很(hen)(hen)(hen)大(da)(da)(da)(da)的(de)限制。工一(yi)般(ban)電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)比較(jiao)(jiao)多，適(shi)用于小部件(jian)(jian)；熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)一(yi)般(ban)用于電力設備和構件(jian)(jian)，適(shi)用于大(da)(da)(da)(da)的(de)部件(jian)(jian)和設備。當然他們的(de)價格也相對便宜一(yi)些。建設部已正式下文，淘汰技(ji)術落后的(de)冷鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)，不(bu)準用冷鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)作水、煤氣管(guan)(guan)。

隨著鋼(gang)(gang)結構(gou)(gou)在建筑(zhu)材(cai)料中的(de)(de)(de)興起(qi)，越(yue)(yue)來越(yue)(yue)多的(de)(de)(de)人選擇使用鋼(gang)(gang)結構(gou)(gou)樓(lou)承(cheng)(cheng)板(ban)了，鋼(gang)(gang)結構(gou)(gou)構(gou)(gou)件工(gong)(gong)廠產業化生產大大縮短了工(gong)(gong)程工(gong)(gong)期，而樓(lou)板(ban)的(de)(de)(de)施工(gong)(gong)方法卻成為影(ying)響工(gong)(gong)期的(de)(de)(de)重要因素。采用那一代(dai)樓(lou)承(cheng)(cheng)板(ban)對于樓(lou)板(ban)的(de)(de)(de)耐火性能也有(you)區(qu)別。樓(lou)承(cheng)(cheng)板(ban)的(de)(de)(de)厚(hou)度(du)一般(ban)都是(shi)按保險(xian)起(qi)見(jian)設計(ji)的(de)(de)(de)比較厚(hou)，正常情況下鋼(gang)(gang)梁之間的(de)(de)(de)跨度(du)在2m以(yi)內(nei)樓(lou)承(cheng)(cheng)板(ban)厚(hou)度(du)在0.75-0.8mm就可以(yi)了，2-2.5m樓(lou)承(cheng)(cheng)板(ban)厚(hou)度(du)用0.8-1.0就可以(yi)了，跨度(du)在3-4米(mi)樓(lou)承(cheng)(cheng)板(ban)厚(hou)度(du)用1.5mm，超(chao)過(guo)5m的(de)(de)(de)跨度(du)是(shi)用臨時(shi)支(zhi)撐，因素就是(shi)混泥土澆筑(zhu)的(de)(de)(de)高(gao)度(du)，混泥土澆筑(zhu)的(de)(de)(de)越(yue)(yue)高(gao)，樓(lou)承(cheng)(cheng)板(ban)所(suo)需要的(de)(de)(de)厚(hou)度(du)也就越(yue)(yue)厚(hou)，還有(you)一個大家容(rong)易忽略的(de)(de)(de)因素就是(shi)螺釘的(de)(de)(de)好壞也是(shi)決定樓(lou)承(cheng)(cheng)板(ban)厚(hou)度(du)的(de)(de)(de)，螺釘越(yue)(yue)好樓(lou)承(cheng)(cheng)板(ban)的(de)(de)(de)承(cheng)(cheng)載(zai)力就越(yue)(yue)強。

C型鋼價格鍍鋅板開平的整個生產來說它首先就是要達到很高的工藝，但是如果要讓它在自己的工藝性上面達到很高的表現，也是要讓它達到很高的要求的，那么它在自己工藝性上面都是要達到什么樣的要求呢？首先一個方面，就是它在自己的生產上面要讓自己有很高的技術，如果是一個廠家，他們沒有很高的技術，那么他們是不能讓自己的工藝性有很好的表現的。商洛C型鋼鍍鋅板開平的(de)整個(ge)設備(bei)上面也(ye)(ye)是很重要的(de)，現(xian)在(zai)也(ye)(ye)有(you)(you)(you)一(yi)些廠(chang)家(jia)(jia)，他(ta)們(men)因為(wei)自(zi)己(ji)(ji)沒有(you)(you)(you)很好的(de)實力(li)，所以(yi)自(zi)然就會讓它在(zai)自(zi)己(ji)(ji)的(de)設備(bei)上面的(de)下降(jiang)，如果是一(yi)些大廠(chang)家(jia)(jia)來說，他(ta)們(men)在(zai)自(zi)己(ji)(ji)的(de)整個(ge)工作中，都是能(neng)使用到電腦(nao)上面的(de)控制，但是對(dui)于有(you)(you)(you)些廠(chang)家(jia)(jia)來說，他(ta)們(men)還在(zai)使用一(yi)些落后的(de)設備(bei)，這樣自(zi)然就會讓它在(zai)工藝(yi)性(xing)(xing)上面下降(jiang)，所以(yi)這一(yi)點也(ye)(ye)是它在(zai)自(zi)己(ji)(ji)工藝(yi)性(xing)(xing)上面的(de)一(yi)些條件(jian)。
