混捏機筒體內壁裝有耐磨襯板，底板是圓形，由六塊扇形襯板組成，中部是卸料閥，閥板表面也裝有襯板。在混捏過程中，各種不同性質、不同粒度的物料在約160℃的混捏溫度狀況下直接與襯板接觸，襯板的磨損主要來自混捏中攪起物料的沖刷，主要失效形式為磨粒磨損，襯板是混捏機的主要消耗大件，對它的國產化有著重要意義，本文詳細分析了國產常用耐磨材料的使用性能，并歸納介紹了近幾年來發展起來的準貝氏體耐磨鋼的耐磨原理及組織性能，在混捏機國產襯板上作了嘗試。

攪刀國產化是此次混捏機備件國產化的重點，一是因為攪刀是混捏機的核心部件，物料的混捏質量狀況與攪刀有作直接的關系；二是因為攪刀是混捏機最大的磨損件和消耗件，而攪刀制作難度大、工藝復雜，需從類似備件制作上參考經驗；三是從成本和時間上考慮，不可能一直依靠進口件，必須盡早實現攪刀的國產化。

進口攪刀的耐磨層是在攪刀基體表面焊一層硬質合金，在后續設備運轉中可以看出，耐磨效果比較好。結合到國內制造技術水平，本次攪刀的國產化采用兩種方式分別試驗，即表層用釬焊的方法鑲嵌硬質合金和在攪刀表層堆焊碳化鎢耐磨焊條，兩種備件加工出來后上線檢驗，觀測使用效果。堆焊攪刀表現出良好的耐磨性和經濟性。

呵呵,一兩個詞組還可以,你拿這么長的一段文章,光專業詞匯就這么多,估計大家都沒有時間給你翻譯.

Kneading Machine wall equipped with wear-resistant cylinder liner, the bottom is round, from six fan-shaped liner composition, is the central discharge valve, valve plates are equipped with surface liner. In kneading process, the different nature of the materials of different particle size of about 160 ° C in the kneading temperature conditions direct contact with the liner, the liner wear mainly from kneading in expanding materials erosion, the main form of failure to abrasive wear, the liner is kneading machine main consumption bulky, it's homemade of great significance, the paper detailed analysis of the wear-resistant materials used in domestic properties, and are now grouped together on the development in recent years of wear-resistant steel-bainite Principle and wear-resistant properties of the Organization, in kneading machine made homemade liner try.

Domestic disturb knife is the kneading machine spare parts localization of the focus, first, because they affect knife is kneading machine core components, materials and the quality of kneading stirred a knife to make a direct relationship; Second, because stirred knife is kneading machine parts and the largest consumption of wear and stirred knife making difficult, complicated process required from the category information on the production of spare parts might experience; Third, from the cost and time considerations, not always rely on imported items must be realized as early as possible disturb the domestic knife.

Imports stirred knife stirred wear-resistant layer in the substrate surface welding knife carbide layer, in the follow-up can be seen in the functioning of equipment, wear-resistant effect of relatively good. Combining the domestic manufacturing technology, this stirred homemade knives were two ways of using tests that the surface using brazing method mosaic stirred Carbide and wear-resistant tungsten carbide knife welding electrode surface, the two spare parts processing out on the line after testing, the use of observation results. Surfacing stirred knife show good wear resistance and the economy.
