class="title">詳細(xì)說(shuō)明</p><div id="82wizrs" class="box"><p><p> 氮化硅結(jié)合碳化硅材料是一類新型耐火材料，該類材料中又包含更細(xì)的類別，如氮化硅結(jié)合碳化硅輻射管、氮化硅結(jié)合碳化硅磚等等。由于該類材料具備多種優(yōu)良性能，氮化硅結(jié)合碳化硅材料因具有的節(jié)能環(huán)保特點(diǎn)更是從眾多同性能產(chǎn)品中脫穎而出，未來(lái)的市場(chǎng)發(fā)展前景良好。1、原料性質(zhì)的影響氮化硅結(jié)合碳化硅制品涉及到的主要生產(chǎn)原料有：碳化硅、硅粉、氮?dú)獾忍砑觿?。不同于普通的氮化硅材料制品，氮化硅結(jié)合碳化硅制品所需要的原料必須具有更高的純度。碳化硅的純度應(yīng)達(dá)到，硅粉的純度應(yīng)達(dá)到99%以上，氮?dú)獾募兌葢?yīng)達(dá)到。除了原料的純度需要進(jìn)行嚴(yán)格的控制之外，四川防腐蝕碳化硅結(jié)合氮化硅批發(fā)，生產(chǎn)加工過(guò)程中還需要對(duì)原料的粒度和顆粒級(jí)配進(jìn)行嚴(yán)格的控制。原料的粒度過(guò)高將會(huì)直接影響胚體成型的體積密度，造成胚體的致密性降低，四川防腐蝕碳化硅結(jié)合氮化硅批發(fā)，影響**終的產(chǎn)品質(zhì)量。在原料顆粒級(jí)配方面，要注意硅粉的粒度，硅粉的粒度控制可以確保硅粉與氮?dú)獾姆磻?yīng)效率，但是一味降低硅粉的粒度也會(huì)存在一定的***影響，即硅粉與氮?dú)夥磻?yīng)速率過(guò)快，劇烈的反應(yīng)造成反應(yīng)裝置中熱量集聚上升，四川防腐蝕碳化硅結(jié)合氮化硅批發(fā)，一旦溫度超過(guò)1400℃時(shí)，會(huì)誘發(fā)碳化硅表面出現(xiàn)流硅現(xiàn)象，反而不利于產(chǎn)品的質(zhì)量控制。另外。奧翔硅碳熱忱歡迎新老客戶惠顧。四川防腐蝕碳化硅結(jié)合氮化硅批發(fā)</p><div

氮化硅結(jié)合碳化硅制品的原料混煉成型后在氮化爐中高溫1400℃左右進(jìn)行燒制，**終產(chǎn)品的質(zhì)量和性能與氮化反應(yīng)的溫度有著緊密關(guān)系。在硅粉與氮?dú)獍l(fā)生反應(yīng)的過(guò)程中，大致經(jīng)歷兩個(gè)溫度段：首先是升溫階段，然后是原料的氮化反應(yīng)階段。其中升溫階段裝置內(nèi)的溫度由初始溫度升高至1100℃左右，而原料氮化反應(yīng)階段的溫度在1100～1350℃。氮化硅結(jié)合碳化硅的干燥制度影響，干燥工序中溫度和時(shí)間對(duì)產(chǎn)品質(zhì)量有較大影響。溫度過(guò)低或時(shí)間過(guò)短，都會(huì)導(dǎo)致胚體中殘留水分，在后續(xù)的氮化反應(yīng)過(guò)程中誘發(fā)硅粉的氧化反應(yīng)，從而降低氮化反應(yīng)效率，影響產(chǎn)品質(zhì)量。溫度升高的快慢也會(huì)對(duì)產(chǎn)品質(zhì)量造成影響。溫度升高太快不利于對(duì)高溫環(huán)境進(jìn)行控制，過(guò)高的溫度會(huì)造成胚體表面出現(xiàn)裂紋。氮化工序之前的裝窯方式可能對(duì)質(zhì)量造成影響的因素是胚體之間的縫隙間隔。胚體之間應(yīng)留有一定的空間，為氮?dú)獾捻槙碀B透填充提供有利條件，避免出現(xiàn)因裝窯總量過(guò)多導(dǎo)致流硅現(xiàn)象。氮化硅結(jié)合碳化硅制品的成型工藝主要有半干法成型和注漿成型兩大類。其中半干法成型因生產(chǎn)效率較高的優(yōu)勢(shì)應(yīng)用更加普遍。國(guó)內(nèi)主要采用的是注漿法成型，這就要求漿料性能一定要好，決定漿料好壞的因素有很多。內(nèi)蒙古鋼廠碳化硅結(jié)合氮化硅供應(yīng)商奧翔硅碳品質(zhì)好、服務(wù)好、客戶滿意度高。</p><div

可制作大、薄型類棚板，這樣可有效的延長(zhǎng)窯具使用壽命，減少耐火材料與制品的比例，節(jié)約能耗。另外,和同面積的其他材料窯具相比，其單位價(jià)格也占有優(yōu)勢(shì)。比如咸陽(yáng)陶瓷研究設(shè)計(jì)院生產(chǎn)的520mm×500mm的氮化硅結(jié)合碳化硅棚板厚度10-12mm,而市場(chǎng)上同面積的高鋁質(zhì)和硅酸鹽結(jié)合SiC棚板等厚度一般都在20-400mm左右，二者比校,氮化硅結(jié)合碳化硅棚板單位重址成倍的減少,單位價(jià)格相比較也便宜。因此，該材料的薄型棚板類，在市場(chǎng)上有很強(qiáng)的競(jìng)爭(zhēng)力。氮化硅結(jié)合碳化硅以其良好的材性可制作輕量化、組合化的支柱中空橫輛類的窯具，此種窯具結(jié)構(gòu)簡(jiǎn)單外觀尺寸小、承受彎曲應(yīng)力大，使用壽命長(zhǎng)從而使產(chǎn)品裝載系數(shù)加大，也大量節(jié)約了能耗是現(xiàn)代窯具的必然發(fā)展趨勢(shì)。氮化硅結(jié)合碳化硅在制作窯具成型工藝上一般有：半干成型、注漿成型和等靜壓成型三種，氮化燒成是制備氮化硅結(jié)合碳化硅材料的關(guān)鍵步驥，其結(jié)果是一定要氮化完全，使制品中的殘留游離硅降至比較低。這里主要是控制反應(yīng)速度，若反應(yīng)過(guò)于激烈、原料中的Si被放出的熱熔融而結(jié)塊，造成反應(yīng)不完全，破壞制品的結(jié)構(gòu)。另外在實(shí)際生產(chǎn)中產(chǎn)品規(guī)格多樣，厚薄各異，要預(yù)先確定每種產(chǎn)品所需的氮化時(shí)間及速度困難較大，氮化難以完全。因此。</p><p> 影響氮化燒結(jié)過(guò)程的主要因素是反應(yīng)的保溫時(shí)間，它是各級(jí)保溫時(shí)間的總和，該時(shí)間與坯體壁厚尺寸關(guān)系比較大。坯體壁較厚時(shí)，所需保溫時(shí)間長(zhǎng)，反之坯體壁較薄時(shí)，所需保溫時(shí)間短。氮化硅結(jié)合碳化硅在氮化爐中燒制時(shí)，我們對(duì)氮化硅材料氮化燒結(jié)環(huán)境下的研究認(rèn)為在燒成反應(yīng)中存在著間接反應(yīng)和直接反應(yīng)。在反應(yīng)中，作為反應(yīng)的參與者，N2的分壓起著極為重要的作用，但不論氮分壓的大小如何，只要生產(chǎn)Si3N4，那么在坯體內(nèi)就存在著N2的濃度梯度和生成Si3N4的濃度梯度，而且這種濃度梯度的方向是相同的，越是接近坯體表面其兩個(gè)組分的濃度越高。要想反應(yīng)不斷向坯體內(nèi)部推進(jìn)就必須確保合適的氮分壓和反應(yīng)溫度。在純Si3N4的氮化燒結(jié)中，通常會(huì)發(fā)生“流硅”反應(yīng)而使氮化反應(yīng)受到影響，這是因?yàn)榈磻?yīng)是一個(gè)放熱反應(yīng)，為使反應(yīng)完全又將Si粉的粒徑控制在很小范圍內(nèi)，這樣在氮化過(guò)程中若控制不當(dāng)時(shí)，供給熱量和生成熱量疊加而使溫度達(dá)到了硅的熔點(diǎn)使Si粉熔化而產(chǎn)生所謂的“流硅”現(xiàn)象。在氮化硅結(jié)合碳化硅的氮化燒結(jié)中，Si粉的濃度含量相對(duì)較低，而濃度較高的SiC又有著較大的導(dǎo)熱率從而了“流硅”現(xiàn)象的發(fā)生。氮化硅結(jié)合碳化硅材料強(qiáng)度大,抗熱震、導(dǎo)熱性好。奧翔硅碳公司狠抓產(chǎn)品質(zhì)量的提高，逐年立項(xiàng)對(duì)制造、檢測(cè)、試驗(yàn)裝置進(jìn)行技術(shù)改造。</p><div
