-250/390碳素球磨机的衬板使用5～6年后,就不能再用,必須更換。为了提高波状衬板的抗磨能力,作者建議在不拆卸球磨机的条件下,直接在其中整个表面上进行熔敷。熔敷使用灰口鉄电极,熔敷厚度5～6毫米,电极电流强度为600安培。气孔缺陷預先用普通电极堆焊平。采用此项建議可使衬板的寿命延长三年。用灰口鉄代替昂貴的斯塔里尼持硬質合金这种做法在工厂中日益广泛。例如加固排烟机叶片表面和輸送带有磨蝕性顆粒物料的螺旋輸送机和风动螺旋泵的表面。灰口铁电极由机修車间的鑄造工段生产。由于采納此項建議节約3196卢布。
-250/390 carbon ball mill liner after 5 to 6 years, it can not be used, you must replace. In order to improve the wiping resistance of the corrugated board, the author suggests that the entire surface of the wiper should be welded directly without disassembling the ball mill. Deposited using gray 鉄 鉄 electrodes, deposited thickness of 5 to 6 mm, the electrode current strength of 600 amps. Stomatal defects pre-ordinary electrode surfacing flat. Adopt this recommendation to extend the life of the liner for three years. The replacement of the expensive Stallini with cemented carbide with gray mouth 这 is becoming more widespread in the factory. Such as reinforcing the face of the smoke evacuator blade and conveying the surface of screw conveyors and pneumatic screw pumps with abrasive particulate material. Gray iron electrode by the mechanic shop casting section production. Thanks to this proposal to save 3196 rubles.
