煙臺道勤耐磨材料有限公司的(de)(de)鑄(zhu)石(shi)和氧化鋁陶瓷其廣泛應用于(yu)電力、礦山、冶金(jin)、煤炭、化工、建筑(zhu)等 工業部(bu)門嚴重磨損腐(fu)蝕的(de)(de)部(bu)件和設(she)備。可延長部(bu)件或(huo)設(she)備的(de)(de)使用壽命(ming)。

鑄石分類：

鑄石具有耐(nai)腐蝕(shi)、耐(nai)磨性能，但其韌性、抗(kang)沖(chong)擊性較(jiao)差，切削加工(gong)困難。鑄石制品(pin)主要有鑄石管(guan)、鑄石復合管(guan)、鑄石板(ban)和鑄石料，灰渣(zha)溝鑲板(ban)多少(shao)錢，已(yi)被廣泛應用(yong)在電力、煤炭(tan)、礦山(shan)、冶金、化(hua)工(gong)、建筑等工(gong)業部門(men)的嚴重磨損、腐蝕(shi)部位(wei)。可延長(chang)部件(jian)或(huo)設(she)備的使用(yong)壽命。由于(yu)鑄石制品(pin)的韌性較(jiao)差，灰渣(zha)溝鑲板(ban)廠家，硬(ying)度(du)較(jiao)高，灰渣(zha)溝鑲板(ban)，難以(yi)切削加工(gong)，一般按一定形狀(zhuang)和尺寸加工(gong)制品(pin)。其固定方(fang)式采(cai)用(yong)砌筑和鑲嵌的方(fang)法(fa)。

按(an)采用的主要(yao)原料分為(wei)天然巖(yan)(yan)石鑄(zhu)(zhu)石（玄武巖(yan)(yan)、輝綠巖(yan)(yan)等基性巖(yan)(yan)、以及頁巖(yan)(yan)）和工業(ye)廢渣(zha)（高爐(lu)礦渣(zha)、鋼(gang)渣(zha)、銅渣(zha)、鉻(ge)渣(zha)、鐵合金渣(zha)等）鑄(zhu)(zhu)石。

按微觀結(jie)構分(fen)為普(pu)通鑄(zhu)石和微晶鑄(zhu)石。

按制造方法分為(wei)澆注制品(pin)（普(pu)型板(ban)材、異型板(ban)材和管材）、燒(shao)結制品(pin)、鑄(zhu)(zhu)石粉和鑄(zhu)(zhu)石塑料復合制品(pin)等。

道勤公(gong)司經營的主要產品有鑄(zhu)(zhu)石(shi)(shi)板(ban)、鑄(zhu)(zhu)石(shi)(shi)管(guan)、鑄(zhu)(zhu)石(shi)(shi)復合(he)管(guan)、夾(jia)套鑄(zhu)(zhu)石(shi)(shi)管(guan)、鑄(zhu)(zhu)石(shi)(shi)粉、氧化鋁陶(tao)(tao)瓷(ci) 板(ban)、氧化鋁陶(tao)(tao)瓷(ci)管(guan)、氧化鋁陶(tao)(tao)瓷(ci)復合(he)管(guan)、氧化鋁陶(tao)(tao)瓷(ci)球，壓延微晶(jing)板(ban)、柔性管(guan)接頭、耐磨(mo)伸(shen)縮節、耐磨(mo) 閥門及多種耐磨(mo)耐腐膠泥等(deng)。

鑄石在防(fang)腐蝕工程中應用較(jiao)早，已有幾十年歷史。鑄石具(ju)有結構緊密，吸水率小(xiao)，抗壓強度高(gao)，耐磨性好的特點(dian)。

鑄石(shi)(shi)板(ban)(ban)(ban)(ban)材有(you)普(pu)形(xing)(xing)(xing)、普(pu)異(yi)(yi)形(xing)(xing)(xing)、特異(yi)(yi)形(xing)(xing)(xing)三大類。普(pu)形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)材有(you)矩形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)、梯形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)、六(liu)角形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)、扇形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)、圓形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)等；普(pu)異(yi)(yi)形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)有(you)弧(hu)形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)、溜槽鑲(xiang)板(ban)(ban)(ban)(ban)、灰渣溝(gou)(gou)直溝(gou)(gou)鑲(xiang)板(ban)(ban)(ban)(ban)等；特異(yi)(yi)形(xing)(xing)(xing)板(ban)(ban)(ban)(ban)有(you)：雙(shuang)曲(qu)面(mian)板(ban)(ban)(ban)(ban)、錐面(mian)板(ban)(ban)(ban)(ban)、蓖條(tiao)篩鑄石(shi)(shi)板(ban)(ban)(ban)(ban)及灰渣溝(gou)(gou)彎(wan)溝(gou)(gou)、變徑、匯合口、二岔口、三岔口板(ban)(ban)(ban)(ban)等。繁多的設備(bei)襯里鑄石(shi)(shi)板(ban)(ban)(ban)(ban)均包括在上(shang)述類別的制品(pin)之內。

鑄石(shi)其(qi)廣(guang)泛應用(yong)于電力、礦山(shan)、冶金、煤炭、化工、建筑等(deng)工業部門嚴重(zhong)磨損腐蝕的部件和(he)設(she)備。可(ke)延長部件或(huo)設(she)備的使(shi)用(yong)壽命。
