耐候鋼厚度-耐候鋼成品

　　厚度是耐候鋼的(de)(de)(de)(de)基(ji)本尺(chi)寸，厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)是(shi)耐(nai)候(hou)(hou)鋼(gang)(gang)極其重要的(de)(de)(de)(de)質量指標。為了(le)獲得具有相同板(ban)差(cha)和(he)不(bu)同板(ban)差(cha)的(de)(de)(de)(de)高(gao)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)板(ban)，并提高(gao)耐(nai)候(hou)(hou)鋼(gang)(gang)的(de)(de)(de)(de)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)和(he)成品率(lv)，必(bi)須(xu)不(bu)斷開發和(he)應用(yong)各種先進(jin)的(de)(de)(de)(de)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)系統(tong)(tong)。當今耐(nai)候(hou)(hou)鋼(gang)(gang)軋制(zhi)中使(shi)用(yong)的(de)(de)(de)(de)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)系統(tong)(tong)有多種，包括電動(dong)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)、液壓(ya)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)、監控(kong)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)、前(qian)饋(kui)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)和(he)精(jing)(jing)(jing)(jing)密測厚(hou)(hou)(hou)儀厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)系統(tong)(tong)等。耐(nai)候(hou)(hou)鋼(gang)(gang)軋機的(de)(de)(de)(de)耐(nai)候(hou)(hou)鋼(gang)(gang)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)是(shi)指當它(ta)們(men)用(yong)于工業(ye)生產時，通過(guo)在耐(nai)候(hou)(hou)鋼(gang)(gang)軋機上使(shi)用(yong)不(bu)同的(de)(de)(de)(de)自(zi)動(dong)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)控(kong)制(zhi)方法(fa)和(he)方法(fa)，可以達到(dao)(dao)的(de)(de)(de)(de)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)水(shui)(shui)平(ping)。耐(nai)候(hou)(hou)鋼(gang)(gang)的(de)(de)(de)(de)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)可以在1990年之前(qian)達到(dao)(dao).根據數據，它(ta)已經達到(dao)(dao)了(le)大約525米(mi)。從1990年到(dao)(dao)1998年，耐(nai)候(hou)(hou)鋼(gang)(gang)的(de)(de)(de)(de)厚(hou)(hou)(hou)度(du)(du)(du)(du)(du)(du)水(shui)(shui)平(ping)得到(dao)(dao)了(le)進(jin)一步提高(gao)，這(zhe)可以達到(dao)(dao)更高(gao)的(de)(de)(de)(de)精(jing)(jing)(jing)(jing)度(du)(du)(du)(du)(du)(du)水(shui)(shui)平(ping)。

　　耐候鋼產品的厚(hou)度精度可以達(da)到(dao)525m或更高的原因是(shi)在軋制過程中(zhong)使用了各種自動厚(hou)度控(kong)制系統。

　　在耐候鋼軋制(zhi)(zhi)生(sheng)產過程中(zhong)，常用(yong)的自動(dong)控制(zhi)(zhi)系統(tong)有(you):壓下位置自動(dong)控制(zhi)(zhi)系統(tong)和電厚度(du)自動(dong)控制(zhi)(zhi)系統(tong)

　　制造系統(電動AGC)、液壓厚(hou)度自(zi)動控制系統(液壓AGC)、監(jian)控AGC、前饋AGC、近測(ce)厚(hou)儀厚(hou)度自(zi)動控制系統等。
