耐火澆注料一般具有較高的常溫強度(du),可以制成預制件(jian)在窯(yao)(yao)爐(lu)旋(xuan)工(gong)(gong)現場安裝,如連鑄的中(zhong)間(jian)罐(guan)用(yong)耐火(huo)澆注料堰板預制件(jian)安裝耐火(huo)澆注料主(zhu)要應用(yong)于冶金工(gong)(gong)業窯(yao)(yao)爐(lu),也在石(shi)油、化(hua)工(gong)(gong)、建材、電力和機械工(gong)(gong)業窯(yao)(yao)爐(lu)和熱工(gong)(gong)設備(bei)中(zhong)廣泛使用(yong)。主(zhu)要按氣孔率(lv)、結(jie)合(he)劑、骨料品(pin)種(zhong)分(fen)類。在實際使用(yong)中(zhong)還(huan)經常以使用(yong)溫度(du)或功能特點(dian)進行分(fen)類。
按氣孔率分: 有(you)致(zhi)密(mi)耐(nai)火澆(jiao)注料和氣孔率不低于45%的(de)隔熱(re)耐(nai)火燒注料兩種。
按結(jie)(jie)合劑分:有水(shui)硬(ying)(ying)性(xing)結(jie)(jie)合、化(hua)(hua)學結(jie)(jie)合、凝聚(ju)結(jie)(jie)合耐火澆(jiao)(jiao)注(zhu)料(liao)(liao)。水(shui)硬(ying)(ying)性(xing)結(jie)(jie)合澆(jiao)(jiao)注(zhu)料(liao)(liao)在(zai)常溫下(xia)凝結(jie)(jie)硬(ying)(ying)化(hua)(hua)并通(tong)(tong)過水(shui)化(hua)(hua)作用而硬(ying)(ying)化(hua)(hua),主要(yao)品種有硅酸鹽水(shui)泥(ni)、普通(tong)(tong)鋁(lv)酸鈣(gai)(gai)水(shui)泥(ni)、純(chun)鋁(lv)酸鈣(gai)(gai)水(shui)泥(ni)、電熔純(chun)鋁(lv)酸鈣(gai)(gai)水(shui)泥(ni)澆(jiao)(jiao)注(zhu)料(liao)(liao)等。化(hua)(hua)學結(jie)(jie)合澆(jiao)(jiao)注(zhu)料(liao)(liao)在(zai)常溫下(xia)一(yi)般通(tong)(tong)過加入促(cu)硬(ying)(ying)劑形(xing)成(cheng)化(hua)(hua)學反(fan)應而硬(ying)(ying)化(hua)(hua),主要(yao)品種有水(shui)玻(bo)璃、硫酸鋁(lv)、磷酸鹽澆(jiao)(jiao)注(zhu)料(liao)(liao)等。凝聚(ju)結(jie)(jie)合澆(jiao)(jiao)注(zhu)料(liao)(liao)為在(zai)煅燒過程中經燒結(jie)(jie)作用而硬(ying)(ying)化(hua)(hua)主要(yao)品種有粘土澆(jiao)(jiao)注(zhu)料(liao)(liao)等。
按耐火骨(gu)料(liao)分有(you)粘土(tu)質(zhi)骨(gu)料(liao)(Al2O330%45%)、高(gao)鋁質(zhi)骨(gu)料(liao)(Al2O3%26ge;45%)、硅質(zhi)骨(gu)料(liao)(SiO2%26ge;85%、Al2O3%26lt;10%)、堿(jian)性骨(gu)料(liao)(有(you)鎂(mei)砂、白云石等)、特(te)殊骨(gu)料(liao)(有(you)碳、碳化物、尖晶(jing)石、鋯英石、氮化物等)和隔熱骨(gu)料(liao)(有(you)珍珠巖、蛭石、陶(tao)粒(li)、漂珠、輕質(zhi)磚砂、多(duo)孔(kong)熟(shu)料(liao)、氧化鋁空心球等)。
在實際使(shi)用中,根據工(gong)程(cheng)要求允許采用某些(xie)混合骨料(liao)種碳纖維(wei)澆注(zhu)(zhu)一體(ti)式抽油(you)(you)(you)桿(gan)扶(fu)正(zheng)(zheng)(zheng)器屬于油(you)(you)(you)田生產用配(pei)件(jian),包(bao)括(kuo)碳纖維(wei)扶(fu)正(zheng)(zheng)(zheng)體(ti)、油(you)(you)(you)油(you)(you)(you)桿(gan),碳纖維(wei)扶(fu)正(zheng)(zheng)(zheng)體(ti)和抽油(you)(you)(you)桿(gan)一次(ci)性澆注(zhu)(zhu)成(cheng)一體(ti)。用新(xin)型直接(jie)將碳纖維(wei)扶(fu)正(zheng)(zheng)(zheng)體(ti)一次(ci)性澆注(zhu)(zhu)在抽油(you)(you)(you)桿(gan)上,省(sheng)去(qu)了原(yuan)有通過媒體(ti)件(jian)的方法進(jin)行作用,也省(sheng)去(qu)了工(gong)人在現場下(xia)井時重復安裝傳統(tong)扶(fu)正(zheng)(zheng)(zheng)器的時間(jian),牢(lao)固性極高,同(tong)時減少了繁瑣的部件(jian),制造安裝都很方便,并且(qie)體(ti)重輕了,成(cheng)本低,耐磨性是傳統(tong)扶(fu)正(zheng)(zheng)(zheng)體(ti)的1.8倍,提高了修井周期,節省(sheng)檢修費用。
