為了保護(hù)鉆具和套管在鉆井過(guò)程中不至于過(guò)度磨損，采用堆焊方式或(其他方法)將堆焊材料沿鉆桿接頭圓周方向堆焊(或熔敷)寬約30～50mm、厚2～3mm的環(huán)形帶。此環(huán)形帶即稱(chēng)之為鉆桿接頭耐磨帶。目前在工程上使用的耐磨帶堆焊材料主要有鐵基合金粉末、碳化鎢顆粒和耐磨帶焊絲。 </p> <p> <br /> </p> <p> 一、鐵基合金粉末 </p> <p> <br /> </p> <p> 鐵基合金粉末是通過(guò)調(diào)整18-8型或Cr13型不銹鋼的Ni、Cr含量，并添加B、Si元素而成的。鐵基合金粉末的噴涂層硬度、致密性、結(jié)合強(qiáng)度等于鎳基合金粉末涂層大體相當(dāng)，因此在不少場(chǎng)合下可代替鎳基合金粉末，但涂層的韌性低于鎳基合金粉末涂層。鐵基合金粉末涂層具有良好的耐磨性。 </p> <p> <br /> </p> <p> 鉆桿接頭耐磨帶堆焊鐵基合金粉末采用的是等離子弧堆焊方法。等離子弧堆焊是利用轉(zhuǎn)移型等離子弧作為熱源，以鐵基合金粉末作填充金屬的一種堆焊工藝。其焊接溫度較高，容易造成局部組.織變大，且重復(fù)堆焊性變差，在應(yīng)用過(guò)程中，容易出現(xiàn)耐磨帶的開(kāi)裂和剝落。 </p> <p> <br />

</p> <p> <br /> </p> <p> 1，高的屈服強(qiáng)度，避免刀刃端在高應(yīng)力下壓潰變形； </p> <p> <br /> </p> <p> 2，足夠高的硬度，增加耐磨性，減少刀圈磨損； </p> <p> <br /> </p> <p> 3，良好的沖擊韌性，提高材料裂紋擴(kuò)展功，防止刀圈斷裂； </p> <p> <br /> </p> <p> 4，良好的抗回火性能，提高材料的熱穩(wěn)定性，保證刀圈在熱裝和滾壓巖體過(guò)程中不降低硬度； </p> <p> <br /> </p> <p> 等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開(kāi)后自激冷卻，形成一層高性能的合金層，從而實(shí)現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。 </p> <p> <br /> </p> <p> </p> <p> <br /> 上海鉆桿堆焊未來(lái)會(huì)有怎樣的發(fā)展方向？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="重慶房車(chē)鉆桿堆焊**設(shè)備,鉆桿堆焊"

為了解決截齒在采煤過(guò)程中的快速磨損失效問(wèn)題，采用堆焊方式（或其他冶金方式）在截齒錐頂（硬質(zhì)合金刀頭）以下齒體部位，沿圓周方向堆焊一個(gè)寬度約20-30mm、厚度2-3mm的環(huán)形帶。此環(huán)形帶即稱(chēng)之為耐磨堆焊層。常用的耐磨堆焊材料為馬氏體堆焊合金（Ｄ３１７，Ｄ３２７，ＤＧ７等）、高鉻Fe-Cr-C合金系（Ｄ６８８，Ｄ６３８等）、碳化鎢、碳化鈮等。從機(jī)理上講，截齒耐磨堆焊層的作用是： </p> <p> <br /> </p> <p> 1、彌補(bǔ)或改變因硬質(zhì)合金刀頭釬焊工藝在齒體圓周形成的性能劣化現(xiàn)象（指先熱處理后釬焊工藝生產(chǎn)的截齒）。 </p> <p> <br /> </p> <p> 2、進(jìn)一步優(yōu)化或強(qiáng)化刀頭部分使用性能。當(dāng)然，采用先釬焊刀頭后整體熱處理截齒的制造工藝時(shí)，后者的作用更為突出。然而，實(shí)際情況并不簡(jiǎn)單，截齒耐磨堆焊層的出現(xiàn)和使用，將截齒刀頭與被切割煤巖之間的磨擦、沖擊等作用，轉(zhuǎn)換為或部分轉(zhuǎn)換為堆焊層與被切割煤巖之間的磨擦、沖擊等作用。它們之間的磨擦磨損、沖擊損傷等，不僅取決于兩個(gè)接觸體材料的特性及其匹配行為，同時(shí)還受到采煤過(guò)程中諸多因素的影響。
