巴氏合金静止浇注
静止浇注过程如下：①根据浇注的轴瓦的尺寸大小，选择合适的工装。在洁净、干燥的平台上，铺上预热过的石棉板。②迅速将刚镀锡并检查合格的轴瓦平稳地放置在经预热的石棉板上，要使其整个下端面完全接触石棉板，以免跑火。③经热加工的金属芯(金属芯的预热温度300℃)平稳地放入待浇注的轴瓦内，找正并使轴瓦的内圆与金属芯的外圆之间的间隙均匀一致，且保证有足够的加工余量。④用专用工装将其紧固，并用沙子或石棉在其周围煨好，防止跑火。⑤以上几个步骤应在5 min 内完成，保证其在浇注前温度不低于280℃，否则需要重新镀锡。⑥浇注时，金属液流要短而均匀、连续地沿胎具圆周移动。⑦在浇注过程中，用预热过的搅拌棒沿瓦体圆周垂直搅动， 以利于合金液中的杂质上浮、气体排出和合金补缩。⑧当轴承合金全部浇入后，应从瓦胎外圆喷水冷却。同时，灵活掌握用***焊枪烘烤合金液较后凝固的部位，保证其从下而上顺序凝固，以防瓦体上部提前凝固。⑨合金完全凝固，温度降至204℃以下后，停止喷水，并拆除胎具，将其清理干净，轻吊放于100℃左右的炉中，缓慢冷却至室温。
Babbit still pouring
The still pouring process is as follows: ① according to the size of the bush pouring, select appropriate tooling. In a clean, dry platform, covered with asbestos sheets preheated. ② quickly just tinned and check qualified bush ***ooth placement on asbestos board preheated, you want to make the entire end face full contact with asbestos board, so as not to run the fire. ③ After thermal processing of the metal core (metal core of the preheating temperature of 300 ° C) be ***oothly placed in the bush to be cast, is looking and a gap between the inner circle and the metal core cylindrical bush uniform, and ensure there are a sufficient allowance. ④ with special tooling to tighten it and around it with sand or asbestos simmer good to prevent running fire. ⑤ over several steps should be completed within 5 min before pouring temperature of not less than 280 ° C, or the need to re-tinned. ⑥ casting, the flow of metal to short and uniform, continuously along the tire with the circumferential movement. (7) in the casting process, with a stirring rod along the tile body circumference vertical agitation preheated to facilitate floating impurities in the liquid alloy, gas discharge and alloy feeding. ⑧ When the bearing alloy is poured into, should watts tire the cylindrical spray cooling. At the same time, flexibility acetylene welding torch baking alloy liquid than the solidification parts from under solidification prevent watt upper body ahead of solidification. ⑨ the alloy is completely solidified, the temperature dropped below 204 ℃ stop water, and removal of the mold, be clean, light hanging put in the oven at 100 ° C or about, and slowly cooled to room temperature.
