等靜壓電爐石墨坩堝

等靜壓電爐石墨坩堝主要原材料的表面描述。熔銅碳化硅坩堝品質(zhì)耐用度zui關(guān)鍵是其配方和生產(chǎn)工藝。所以挑選一款好的中頻電爐熔銅碳化硅坩堝不能只看表面價(jià)格，而是選擇配方，工藝均優(yōu)的品牌商家。熔湯在舀出后，請(qǐng)注意不應(yīng)留殘湯。被凝固的殘湯在下次的熔解時(shí)由于急速熱膨脹是造成坩堝破裂的原因。
對(duì)于坩堝內(nèi)的燃燒，一定要注意爐內(nèi)設(shè)計(jì)及調(diào)整燃燒器使其在坩臺(tái)和坩堝下方進(jìn)行*燃燒。如圖所示，按的順序材質(zhì)變紅是理想的。加熱時(shí)，應(yīng)注意不要在過(guò)氧化狀態(tài)中進(jìn)行，盡可能在短時(shí)間內(nèi)進(jìn)行急速升溫。

造*好坩堝，創(chuàng)百年老品牌使用方法
石墨坩堝型號(hào)規(guī)格使用說(shuō)明 
1、石墨坩堝存放在通風(fēng)干燥的環(huán)境中，以免受潮影響使用。 
2、石墨坩堝在搬運(yùn)中要輕拿輕放，嚴(yán)禁摔震， 切勿滾動(dòng)，以免損壞坩堝表面的保護(hù)層。 
3、使用前要提前對(duì)坩堝進(jìn)行烘烤，烘烤溫度由低到高徐徐升溫， 并不斷翻動(dòng)坩堝，讓其均勻受熱，排除坩堝體內(nèi)的水分，預(yù)熱溫度逐步升到500 以上（如預(yù)熱不當(dāng)，造成坩堝剝落、爆裂，不屬質(zhì)量問(wèn)題恕不退換） 
4、石墨坩堝爐要與坩堝配套，上下和周?chē)障兑弦?，爐蓋不能壓在堝體上。 
5、使用時(shí)要避免火焰直噴坩堝體，應(yīng)噴向坩堝底座。 
6、加料時(shí)應(yīng)慢慢加入，是碎料，大料不要裝的太多、太緊，以免漲裂坩堝。 
7、裝、出爐所用的坩堝鉗要和坩堝外型相符，以免夾壞坩堝。 
8、坩堝是連續(xù)使用，這樣才能更好的發(fā)揮它的高性能。 
9、熔煉過(guò)程中須加劑的投入量，過(guò)量的使用會(huì)降低坩堝的使用壽命。 
10、使用坩堝時(shí)要周期性的轉(zhuǎn)動(dòng)坩堝，使其受熱均勻，延長(zhǎng)使用。 
11、清除石墨坩堝內(nèi)外壁熔渣和粘焦時(shí)應(yīng)輕敲，避免損壞石墨坩堝。

錯(cuò)誤的做法：在支撐磚和坩堝之間留下的空隙太小，坩堝膨脹受阻會(huì)裂開(kāi)。
Wrong practice：The space left between the support brick and the crucible is too small, the crucible expansion will be blocked will crack. 
正確的做法：在支撐磚和坩堝之間插入小木片，木片會(huì)燃燒掉從而留下足夠的空隙。
Right practice：I n s e r t a small piece of wood between the support brick and the crucible, and the wood burns away to leave enough clearance.
錯(cuò)誤的做法：爐子頂部沒(méi)有*密封，坩堝頂部容易受到氧氣氧化，從而產(chǎn)生豎直裂紋。
Wrong practice：The top of the furnace is not compley sealed, and the top of the crucible is susceptible to oxygen oxidation, resulting in a vertical crack.
正確的做法：用保溫棉把爐沿密封
Right practice：Use heat insulation cotton to seal the furnace along.
一、安裝坩堝前，必須先檢查爐膛內(nèi)部：爐壁和爐底應(yīng)該是完好無(wú)損，必須干燥，沒(méi)有金屬或爐渣附著。如果爐壁或爐底附著水泥或爐渣，必須要進(jìn)行清理。否則火焰的前進(jìn)會(huì)受到阻礙而使火焰方向發(fā)生偏轉(zhuǎn)，從而造成坩堝局部受熱過(guò)度，在坩堝壁上發(fā)生氧化或產(chǎn)生小洞。
First, before the crucible is installed, the inside of the furnace must be checked. The furnace wall and the bottom should be intact, must be dry, no metal or slag adhesion. It must be cleaned up If the furnace wall or bottom adhesion of cement or slag. Otherwise, the advance of the flame will be hindered and the direction of the flame will be deflected, resulting in the local overheating of the crucible, oxidation or small hole on the crucible wall. 
二、坩堝的底部支撐：
Second, the bottom of the crucible support:
1.安裝坩堝時(shí)，坩堝的底部支撐必須使用表面平整的、足夠大的圓柱形底座，底座的直徑至少要與坩堝的底部相同，是略大2-3cm，且底座高度略高于出火口，從而防止火焰直接燒到坩堝底部。否則容易造成底部材料迅速被侵蝕，坩堝變成錐形，或由于坩堝底部受力不均而使坩堝開(kāi)裂。Install the crucible, crucible bottom supporting large enough of a cylindrical base must be used with smooth surface, and the base diameter of at least to the bottom of the crucible, preferably 2-3cm, and the base height is slightly higher than the outlet, thereby preventing direct flame burn at the bottom of the crucible. Otherwise, it is easy to cause the bottom material to be eroded rapidly, and the crucible is tapered, or the crucible is cracked due to the uneven force at the bottom of the crucible.
2.為防止坩堝與底座粘連，可以在坩堝與底座間放一層隔離物（如：細(xì)耐火砂或高溫棉。）
In order to prevent the crucible from sticking to the base, a layer of isolation between the crucible and the base (e.g., fine sand or high temperature) can be provided. 
3.在傾轉(zhuǎn)爐中使用卡隼式底座時(shí)，必須保證底座的凸起和坩堝凹槽是互相匹配的。如果底座的凸起太高或者尺寸太大，坩堝底部會(huì)受到擠壓，必然造成底部破裂，而且在傾倒后，坩堝不能被有效地固定。Use a tenon type base in tilting converter, must ensure that the base bulge and the groove is matched in the crucible. If the height of the base is too high or the size is too large, the bottom of the crucible will be squeezed, and the bottom will be broken. After the dumping, the crucible cannot be effectively fixed.
4.安裝帶長(zhǎng)澆嘴的傾轉(zhuǎn)爐坩堝時(shí)，要提供高度合適的底座并把坩堝支撐固定好，如果底座支撐不合適，此類(lèi)?ài)釄鍟?huì)只靠澆嘴“懸掛”在爐子內(nèi)。這樣坩堝會(huì)從上部斷裂掉。
When installing a tilting converter crucible with a long spout, a highly suitable base is provided and the crucible is secured to the support, and if the base is not properly supported, such a crucible will be suspended in the furnace only by the spout. So the crucible will break from the top. 
三、坩堝與支撐磚間的空隙：
Third, the gap between crucible and support brick:
1.坩堝與支撐磚間的空隙太小，坩堝受熱膨脹后會(huì)受阻裂開(kāi)，可在坩堝和爐壁頂部支撐磚間直接放置可燃物（插入小木片或紙板），在坩堝加熱后，可燃物會(huì)燃燒掉從而留下足夠的空間。The gap between the crucible and the supporting brick is too small, after the expansion of the heated crucible will be blocked in the crack, crucible and furnace wall top supporting brick directly placing combustibles (i n s e r t the small pieces of wood or cardboard), in the crucible after heating, fuel burn down and leave enough space.
2.對(duì)于在側(cè)面排廢氣的爐子，坩堝和爐壁之間可以用保溫棉密封，然后用耐高溫水泥固定。這樣既可以防止因爐頂沒(méi)有*密封，而使坩堝頂部氧化而裂開(kāi)，且在坩堝受熱向上膨脹時(shí)不會(huì)受阻裂開(kāi)。For exhaust gas in the side of the stove, crucible and furnace wall can be sealed with insulation cotton, and then fixed with high temperature cement. This prevents both the top of the crucible from being oxidized and cracked by the top of the crucible due to incomplete sealing of the furnace roof, and is prevented from cracking when the crucible is heated upwardly.
（注：建議使用爐沿蓋來(lái)防止坩堝的氧化、頂部開(kāi)裂和腐蝕。爐沿蓋的內(nèi)邊要覆蓋住坩堝內(nèi)表面100mm處，能更好地避免坩堝受到外力撞擊和被氧化。）(Note: It is recommended to use the cover to prevent the oxidation of the crucible furnace top, cracking and corrosion. The inner side of the furnace cover is covered with the inner surface of the crucible 100mm, so as to avoid the impact of the external force and the oxidation of the crucible.)
3.在傾轉(zhuǎn)爐中，應(yīng)該在坩堝一半高度的位置上，有一塊或兩塊支撐磚在澆嘴的下方把坩堝固定。應(yīng)在坩堝和支撐磚之間放入34cm左右的高溫棉，以保留足夠的空間防止坩堝膨脹時(shí)受阻。
In the tilting furnace, one or two supporting bricks should be positioned below the crucible at a height of half the crucible to hold the crucible below the spout. You should be placed between the crucible and support brick around 3 4cm high temperature cotton, in order to retain enough space to prevent the crucible expansion blocked.
