  真空燒(shao)結(jie)(jie)(jie)爐使(shi)(shi)用注(zhu)(zhu)意(yi)(yi)事(shi)項   大多數的真空燒(shao)結(jie)(jie)(jie)爐操作者都知道,該設(she)備雖然(ran)操作簡(jian)單安(an)(an)全(quan),但如果沒有(you)嚴格(ge)按(an)照使(shi)(shi)用規章制度使(shi)(shi)用就會有(you)產生安(an)(an)全(quan)隱患。因此在(zai)(zai)使(shi)(shi)用時,一定要(yao)認(ren)真對(dui)待注(zhu)(zhu)意(yi)(yi)事(shi)項,確保生產安(an)(an)全(quan)。燒(shao)結(jie)(jie)(jie)爐使(shi)(shi)用過度,會發(fa)脆不能接觸(chu)。因此有(you)損壞時應(ying)及(ji)時更換。燒(shao)結(jie)(jie)(jie)爐循環水的保暖(nuan)問題,在(zai)(zai)冬天要(yao)尤(you)為注(zhu)(zhu)意(yi)(yi),以防水管爆(bao)裂。   真空燒(shao)結(jie)(jie)(jie)爐主要(yao)應(ying)用在(zai)(zai)鋼(gang)鐵(tie)行業(ye)、冶金(jin)行業(ye)、新材料行業(ye)等(deng)(deng)。   應(ying)用于硬(ying)質(zhi)(zhi)合(he)(he)金(jin)、銅鎢(wu)合(he)(he)金(jin)、鎢(wu)、鉬、鋁鎳鈷永磁(ci)、SmCo5、Sm2Co17及(ji)釹(nv)鐵(tie)硼(peng)、鈦(tai)合(he)(he)金(jin)等(deng)(deng)合(he)(he)金(jin)材料的真空/氣氛燒(shao)結(jie)(jie)(jie)。   硬(ying)質(zhi)(zhi)合(he)(he)金(jin):高(gao)溫爐燒(shao)結(jie)(jie)(jie)硬(ying)質(zhi)(zhi)合(he)(he)金(jin)刀具已經實現大規模工業(ye)化生產。由于快速燒(shao)結(jie)(jie)(jie),碳化物晶粒細小,產品性能可以得到(dao)大幅(fu)度提高(gao)。   真空燒(shao)結(jie)(jie)(jie)爐燒(shao)結(jie)(jie)(jie)各種鎢(wu)合(he)(he)金(jin)、結(jie)(jie)(jie)各種鐵(tie)基、銅基粉末冶金(jin)零件。

真空甩帶爐的工作方式是什么

  真(zhen)空(kong)甩帶爐(lu)的(de)工作(zuo)(zuo)(zuo)方(fang)式是(shi)(shi)什么(me)   真(zhen)空(kong)甩帶爐(lu)是(shi)(shi)制備(bei)(bei)和(he)開發亞穩材(cai)料(liao)的(de)設(she)備(bei)(bei),該設(she)備(bei)(bei)除具備(bei)(bei)感(gan)應(ying)(ying)爐(lu)的(de)全(quan)部特點(dian)外,還(huan)具有(you)制備(bei)(bei)大(da)塊非晶(jing)和(he)金屬(shu)薄片(pian)(pian)的(de)功能(neng),適用于各種(zhong)非晶(jing)和(he)微(wei)晶(jing)材(cai)料(liao)的(de)研(yan)究和(he)驗(yan)證。廣泛用于新型稀土永磁非晶(jing)軟(ruan)磁材(cai)料(liao)和(he)納(na)米材(cai)料(liao)的(de)科學開發和(he)應(ying)(ying)用研(yan)究。   真(zhen)空(kong)甩帶爐(lu)的(de)加(jia)熱與(yu)(yu)隔(ge)熱襯料(liao)是(shi)(shi)在(zai)真(zhen)空(kong)與(yu)(yu)高溫下(xia)工作(zuo)(zuo)(zuo)的(de),因而對(dui)這(zhe)(zhe)(zhe)些材(cai)料(liao)提出了耐高溫,蒸汽壓(ya)低(di),輻射(she)效果好,導熱系(xi)數小等要求。對(dui)抗(kang)氧化(hua)性能(neng)要求不高。所以,真(zhen)空(kong)甩帶爐(lu)廣泛地采用了鉭、鎢(wu)、鉬和(he)石墨(mo)等作(zuo)(zuo)(zuo)加(jia)熱與(yu)(yu)隔(ge)熱構料(liao)。這(zhe)(zhe)(zhe)些材(cai)料(liao)在(zai)大(da)氣(qi)狀(zhuang)態下(xia)極(ji)易(yi)氧化(hua),因此,常規熱處(chu)理(li)爐(lu)是(shi)(shi)不能(neng)采用這(zhe)(zhe)(zhe)些加(jia)熱與(yu)(yu)隔(ge)熱材(cai)料(liao)。   真(zhen)空(kong)甩帶爐(lu)利(li)用真(zhen)空(kong)感(gan)應(ying)(ying)熔煉法,把(ba)坩(gan)堝(guo)封閉在(zai)真(zhen)空(kong)室中(zhong),利(li)用電磁感(gan)應(ying)(ying)產(chan)生的(de)渦流作(zuo)(zuo)(zuo)為(wei)熱源,在(zai)真(zhen)空(kong)或惰(duo)性氣(qi)體狀(zhuang)態下(xia)把(ba)合金(或是(shi)(shi)導電材(cai)料(liao))原料(liao)進行脫(tuo)氣(qi)、熔化(hua)處(chu)理(li),通過(guo)(guo)坩(gan)堝(guo)傾爐(lu)系(xi)統(tong)澆鑄(zhu),經過(guo)(guo)中(zhong)間包在(zai)水冷輥上(shang)急速(su)凝固后形成薄片(pian)(pian),再(zai)在(zai)水冷盤(pan)上(shang)進行慢速(su)降(jiang)溫,在(zai)撥鑿的(de)攪拌下(xia),把(ba)合金降(jiang)到30℃左右,形成大(da)不薄厚均勻的(de)合金薄片(pian)(pian)的(de)一種(zhong)熔煉設(she)備(bei)(bei)。

真空熔煉爐的組成部件

  真(zhen)空熔(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)的組成部件   真(zhen)空熔(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)由中頻電(dian)源,電(dian)容器(qi)柜,爐(lu)體(ti),機械傾(qing)斜裝(zhuang)置(或液壓(ya)傾(qing)斜裝(zhuang)置),水分(fen)配器(qi),坩堝模具(或石(shi)墨坩堝,鐵(tie)(tie)(tie)坩堝),水冷電(dian)纜(lan),連接銅排等組成。   真(zhen)空熔(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)爐(lu)襯(chen)分(fen)為耐(nai)酸(suan)和(he)耐(nai)堿(jian)。酸(suan)性爐(lu)襯(chen)由石(shi)英砂制(zhi)(zhi)成,石(shi)英砂中二氧(yang)(yang)化(hua)硅(gui)含(han)(han)量超過(guo)(guo)98%。由于(yu)熔(rong)(rong)點(dian)低,穩定性差,因此主(zhu)要用(yong)(yong)于(yu)有色金(jin)屬和(he)鑄鐵(tie)(tie)(tie)的冶(ye)煉(lian)(lian)(lian)(lian)和(he)隔(ge)熱(re)。堿(jian)性爐(lu)襯(chen)由含(han)(han)鎂量超過(guo)(guo)85%的氧(yang)(yang)化(hua)鎂制(zhi)(zhi)成,用(yong)(yong)于(yu)熔(rong)(rong)煉(lian)(lian)(lian)(lian)特殊鋼和(he)鎳(nie)基真(zhen)空感(gan)應(ying)爐(lu)在(zai)冶(ye)煉(lian)(lian)(lian)(lian)過(guo)(guo)程中,金(jin)屬通過(guo)(guo)感(gan)應(ying)加(jia)(jia)(jia)(jia)熱(re),然后傳(chuan)輸(shu)到爐(lu)渣(zha)(zha)(zha)。因此,爐(lu)渣(zha)(zha)(zha)的溫度較低,爐(lu)渣(zha)(zha)(zha)的結構決定了(le)鋼-爐(lu)渣(zha)(zha)(zha)的界面較小。   使(shi)用(yong)(yong)鎳(nie)基合金(jin)時,應(ying)使(shi)用(yong)(yong)更(geng)好的原材(cai)(cai)料(liao),并(bing)且應(ying)根據(ju)每種元素的燒盡情況迅速加(jia)(jia)(jia)(jia)熱(re)和(he)熔(rong)(rong)化(hua)成分(fen)。當大(da)量裝(zhuang)料(liao)熔(rong)(rong)化(hua)后,應(ying)添(tian)加(jia)(jia)(jia)(jia)爐(lu)渣(zha)(zha)(zha)以(yi)減少氧(yang)(yang)化(hua)。爐(lu)渣(zha)(zha)(zha)應(ying)與爐(lu)襯(chen)兼容。完全熔(rong)(rong)化(hua)后,根據(ju)產品的成分(fen)分(fen)批添(tian)加(jia)(jia)(jia)(jia)脫氧(yang)(yang)劑(硅(gui)鐵(tie)(tie)(tie)粉,硅(gui)鈣粉,鋁(lv)粉等),并(bing)在(zai)必要時取樣進行分(fen)析以(yi)調整組成。當組成合格并(bing)且脫氧(yang)(yang)良(liang)好時,可以(yi)放出鋼。鑄鐵(tie)(tie)(tie)在(zai)熔(rong)(rong)化(hua)和(he)保溫過(guo)(guo)程中不會被嚴重(zhong)氧(yang)(yang)化(hua),冶(ye)金(jin)質量要求也很低。合金(jin)使(shi)真(zhen)空熔(rong)(rong)煉(lian)(lian)(lian)(lian)爐(lu)爐(lu)襯(chen)干燥或濕潤,以(yi)使(shi)耐(nai)火材(cai)(cai)料(liao)逐層具有適當的粒徑比。它需(xu)要密集(ji)而不分(fen)層。在(zai)一(yi)次冶(ye)煉(lian)(lian)(lian)(lian)過(guo)(guo)程中,緩慢加(jia)(jia)(jia)(jia)熱(re)以(yi)避免破裂。
