  小(xiao)型真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)有(you)哪些(xie)優(you)點(dian)   小(xiao)型真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)的(de)(de)(de)(de)主(zhu)要(yao)(yao)優(you)點(dian)是:   1、有(you)利(li)于(yu)排除吸附氣(qi)體,對促進燒結(jie)(jie)(jie)后期的(de)(de)(de)(de)收縮作用明顯。   2、真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)對硅,鋁,鎂,鈣等(deng)雜質或(huo)(huo)(huo)其氧化物的(de)(de)(de)(de)排除,起到(dao)提(ti)純材(cai)料(liao)的(de)(de)(de)(de)作用。   3、可(ke)改善液(ye)相燒結(jie)(jie)(jie)的(de)(de)(de)(de)潤濕性,有(you)利(li)于(yu)燒結(jie)(jie)(jie)過程中(zhong)的(de)(de)(de)(de)收縮和改善合金的(de)(de)(de)(de)組(zu)織結(jie)(jie)(jie)構。   4、是理(li)想的(de)(de)(de)(de)惰(duo)性氣(qi)氛,當不(bu)宜用其他還原性或(huo)(huo)(huo)惰(duo)性氣(qi)體時,或(huo)(huo)(huo)者(zhe)對容易(yi)出現(xian)脫碳,滲碳的(de)(de)(de)(de)材(cai)料(liao),均可(ke)采用熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)。   5、小(xiao)型真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)減(jian)少氣(qi)氛中(zhong)的(de)(de)(de)(de)有(you)害成(cheng)分(水,氧,氮等(deng))對產品(pin)的(de)(de)(de)(de)玷污(wu)。例如,電解氫中(zhong)的(de)(de)(de)(de)含(han)水量要(yao)(yao)求降(jiang)(jiang)-40℃較為困難;而(er)真(zhen)(zhen)空(kong)(kong)(kong)燒結(jie)(jie)(jie)時,真(zhen)(zhen)空(kong)(kong)(kong)度只要(yao)(yao)在(zai)(zai)數(shu)百Pa就相當于(yu)含(han)水量為-40℃。6、小(xiao)型真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)熔(rong)(rong)(rong)化速度快,加裝保(bao)(bao)溫(wen)套溫(wen)度可(ke)達(da)到(dao)2100℃2·可(ke)選(xuan)配程序升溫(wen)控溫(wen),根據您的(de)(de)(de)(de)工(gong)(gong)藝要(yao)(yao)求設(she)定(ding)好升溫(wen)或(huo)(huo)(huo)者(zhe)降(jiang)(jiang)溫(wen)曲線,真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)會自動按照此(ci)工(gong)(gong)藝進行加熱或(huo)(huo)(huo)降(jiang)(jiang)溫(wen)。   7、帶傾倒裝置,可(ke)將熔(rong)(rong)(rong)好的(de)(de)(de)(de)試樣(yang)傾倒在(zai)(zai)事先準備(bei)好的(de)(de)(de)(de)錠模內,澆注出您想要(yao)(yao)的(de)(de)(de)(de)樣(yang)品(pin)形狀。   8、小(xiao)型真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)可(ke)在(zai)(zai)多種(zhong)氣(qi)氛條(tiao)件(jian)下(xia)(xia)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian):空(kong)(kong)(kong)氣(qi)狀態(tai)下(xia)(xia)、保(bao)(bao)護氣(qi)氛條(tiao)件(jian)下(xia)(xia)和高(gao)真(zhen)(zhen)空(kong)(kong)(kong)條(tiao)件(jian)下(xia)(xia)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian),買(mai)一種(zhong)設(she)備(bei),實(shi)現(xian)多種(zhong)功能;程度節約您的(de)(de)(de)(de)成(cheng)本。   9、可(ke)選(xuan)配二次加料(liao)系統:真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)可(ke)實(shi)現(xian)在(zai)(zai)熔(rong)(rong)(rong)化過程中(zhong)加入其他元素,方(fang)便您制(zhi)備(bei)出多元化樣(yang)品(pin)。   10、真(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)(lu)爐(lu)(lu)體全不(bu)銹鋼結(jie)(jie)(jie)構,并(bing)帶水冷(leng),保(bao)(bao)證外(wai)殼溫(wen)度低于(yu)35℃,保(bao)(bao)護您的(de)(de)(de)(de)人身(shen)安全。
