中文拼音 [yuánsùshāosǔn]
元素燒損
英文
melting loss of alloying element-
The loss of deoxidizing elements resulting from thermal decomposition of lining materials and the change of total oxygen in molten steel during vim refining are researched
摘要研究真空感應熔煉過程中因爐襯材料熱分解造成的脫氧元素燒損及其全氧含量的變化規律。It ' s pointed out that, under the condition of vim refining, the amount of oxide inclusions residue in molten steel increases with the increased loss of deoxidizing elements, and the key of melting extra - low oxygen steel is to avoid the thermal decomposition of lining material ; the size of deoxidizing products increases with the increased degree of supersaturation of deoxidizing elements ; larger inclusions granules found in extra - low oxygen steel come mainly from lining material
結果表明，在真空感應熔煉條件下，殘留在鋼中的氧化物夾雜數量隨脫氧元素鋁燒損量增加而增加，熔煉超低氧鋼的關鍵是避免爐襯熱分解；脫氧產物尺寸隨脫氧元素過飽和度增加而增加；超低氧鋼的大顆粒夾雜主要來自爐襯材料。Results of the experiments showed that the wear mechanisms of the sintered steel included abrasive wear, adhesive wear and fatigue wear, and it was the abrasive wear most important. it was the sintered steel mixed by ni, mo that was the best on the wear resistance, because of the great lot of bainite ; the sintered steel quenched and low temperature tempered mixed by mo, w that was the best on the wear resistance, because of the rigidity of the steel was the highest
實驗結果表明：本文中幾種燒結鋼的磨損機制均是由磨粒磨損、粘著磨損、和疲勞磨損共同作用的，且以磨粒磨損為主；在燒結態下，復合添加合金元素鎳、鉬的燒結鋼的耐磨性能最好，這是因為生成了大量的硬質相貝氏體；而淬火、低溫回火態下，則復合添加鉬、鎢的燒結鋼的耐磨性能最好，這是因為熱處理態下添加鉬、鎢的燒結鋼的硬度最高。The thesis mainly investigated the bati _ 4o _ 9 ( bt _ 4 ), which has the lowest dielectric loss in ba - ti system, and ( ba, sr ) tio _ 3, the a position substitute compound of batio _ 3. the dielectric properties of bt _ 4 / bst with different preparation way and different elements doping were investigated. a archimedes method, xrd, sem, impedance analyzer, network analyzer and hakki - coleman method were used to investigate the density, phase formation, microstructure, dielectric properties and doping mechanisms
本論文以在ba - ti系中具有最低介電損耗的bati _ 4o _ 9 （ bt _ 4 ）高頻介質陶瓷和batio _ 3a位sr取代而得的（ ba ， sr ） tio _ 3 （ bst ）高頻介質陶瓷作為研究對象，對不同粉體制備方法制備的bt _ 4 / bst高頻電介質材料進行不同元素的摻雜，運用阿基米德方法， x射線衍射分析儀，掃描電子顯微鏡和阻抗分析儀，網路分析儀， hakki - coleman法等方法手段和測試儀器測試燒成樣品的密度，相組成情況，微觀結構和介電性能，探討造成介電性能起伏的形成機理。During the process of foundry charging mixing. the information of loss ratio and consistent chemical composition have been considered which can aid technologists to get the minimum cost mixing schedule for the foundry charging mixing
該系統使用方便，在配比過程考慮到了元素的燒損，這樣一方面實現了準確的爐料配比，另一方面在保證化學成分在控制要求的條件下實現了成本的最低化對實際的鑄件生產有著重要的作用。分享友人
