氮化硅結(jié)合的碳化硅制作的梁材，用于隧道窯、梭式窯、倒焰窯，具有良好的承載能力，為增加窯爐產(chǎn)量充分利用窯爐空間，是比較理想的窯具，同時(shí)可選用立柱作支撐架，使用溫度可達(dá)1400℃。在不增加過多投資的情況下就可以達(dá)到提高產(chǎn)品質(zhì)量，節(jié)能增產(chǎn)的目的，是一種理想的更新?lián)Q代產(chǎn)品。 5、各種耐火件:

style="text-indent:25px">氮化硅結(jié)合碳化硅燒制時(shí)出現(xiàn)的暗點(diǎn)需要進(jìn)一步的改善，先從燒窯工操作上控制煙熏、暗點(diǎn)缺點(diǎn)。煤燒隧道窯的操作受燒窯工的影響因素比較大： l.接班前檢查窯內(nèi)溫度、煤質(zhì)、設(shè)備及窯爐的燃燒情況。 2.加煤前先拌水，煤的含水率為 25 ％- 30 ％。 3.加煤要均勻，四周封嚴(yán)，火層角度和爐棚基本一致，交叉加煤。 4.根據(jù)氣氛變化和排煙風(fēng)機(jī)負(fù)壓表的監(jiān)測(cè)情況，隨時(shí)調(diào)整主閘板開度，保證窯內(nèi)壓力制度平衡。 5.加煤前觀察窯內(nèi)火色，火苗高度兩側(cè)達(dá)到一致，窯內(nèi)凈火后加煤。 6.四人操作要統(tǒng)一，操作要迅速。 7.隨時(shí)觀察窯內(nèi)溫度變化情況，加煤前觀察各燒成帶溫度表是否達(dá)到規(guī)定標(biāo)準(zhǔn)。根據(jù)煤質(zhì)和溫度情況掌握灰層、火層厚度，質(zhì)量煤是厚灰層薄火層，劣質(zhì)煤是薄灰層厚火層。 8.清理爐內(nèi)灰渣前應(yīng)檢查爐子，火層不能過厚，清理爐內(nèi)灰渣以露出火炭為宜，不能太重，擺正爐條，保溫時(shí)要使火層四角落地，不露窟窿，窯爐分清火層、煤層、灰層。交叉清理爐內(nèi)灰渣。以上幾點(diǎn)是改善氮化硅結(jié)合碳化硅燒制時(shí)煙熏、暗點(diǎn)是否減少應(yīng)注意的幾點(diǎn)。 </p><div
