1、爐子初次使用或長時(shí)間不用后，要在120℃左右烘烤1小時(shí)，在300℃左右烘烤2小時(shí)后使用，以免造成爐膛開裂。爐溫盡量不要超過額定溫度，以免損壞加熱元件及爐襯。禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保持爐內(nèi)的清潔。 2、爐膛若采用石英管，當(dāng)溫度高于1000℃時(shí)，石英管的高溫部分會(huì)出現(xiàn)不透明現(xiàn)象，這叫失透是連熔石英管的一個(gè)固有缺陷，屬正?，F(xiàn)象。 3、冷爐使用時(shí)，由于管式爐膛是冷的，須大量吸熱，所以低溫段升溫速率不易過快，各溫度段的升溫速率差別不易太大，設(shè)置升溫速率時(shí)應(yīng)充分考慮所燒結(jié)材料的物理化學(xué)性質(zhì)，以免出現(xiàn)噴料現(xiàn)象，污染爐管。 4、定期檢查溫度控制系統(tǒng)的電器連接部分的接觸是否良好，應(yīng)特別注意加熱元件的各連接點(diǎn)的連接是否緊固。北京節(jié)能管式爐安裝管式爐的優(yōu)點(diǎn)：操作容易，便于控制，能連續(xù)生產(chǎn)。</p><div style="width:100%;text-align: center;"><img style="max-width:

1、開包或移動(dòng)高溫管式爐時(shí)，請(qǐng)托住底座將其提起。請(qǐng)勿握住爐門上提。 2、如果可能，請(qǐng)兩個(gè)或更多人合作搬運(yùn)高溫管式爐。 3、使用前，請(qǐng)去除爐門配件和爐室的包裝材料。 4、請(qǐng)選擇通風(fēng)良好的房間，并將高溫管式爐放在防止熱材料濺出的表面上，遠(yuǎn)離其他熱源。 5、請(qǐng)勿將高溫管式爐放置在易燃表面上。確保高溫管式爐四周有空隙。 6、請(qǐng)勿阻塞控制區(qū)域中的任何通風(fēng)孔：它們是冷卻控件所必需的。 7、確保高溫管式爐的擺放位置有利于快速切斷電源，請(qǐng)參見以下內(nèi)容。 8、如果提供的高溫管式爐未安裝煙囪，則通過爐殼頂部的孔進(jìn)行安裝。 9、如果要使用高溫管式爐加熱會(huì)產(chǎn)生煙的物質(zhì)，則可在煙囪出口上直接連接一個(gè)直徑約為 150毫米的排煙管。 10、請(qǐng)勿密封與高溫管式爐煙囪的連接，因?yàn)檫@會(huì)導(dǎo)致爐室內(nèi)的氣流過多，從而造成爐內(nèi)溫度不均。</p><p
