内蒙轴承合金 轴瓦合金价格 巴氏合金浇铸
价格:122.00
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5min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。BabbitstillpouringThestillpouringprocessisasfollows:①accordingtothesizeofthebushpouring,selectappropriatetooling.Inaclean,dryplatform,coveredwithasbestossheetspreheated.②quicklyjusttinnedandcheckqualifiedbush***oothplacementonasbestosboardpreheated,youwanttomaketheentireendfacefullcontactwithasbestosboard,soasnottorunthefire.③Afterthermalprocessingofthemetalcore(metalcoreofthepreheatingtemperatureof300°C)be***oothlyplacedinthebushtobecast,islookingandagapbetweentheinnercircleandthemetalcorecylindricalbushuniform,andensurethereareasufficientallowance.④withspecialtoolingtotightenitandarounditwithsandorasbestossimmergoodtopreventrunningfire.⑤overseveralstepsshouldbecompletedwithin5minbeforepouringtemperatureofnotlessthan280°C,ortheneedtore-tinned.⑥casting,theflowofmetaltoshortanduniform,continuouslyalongthetirewiththecircumferentialmovement.(7)inthecastingprocess,withastirringrodalongthetilebodycircumferenceverticalagitationpreheatedtofacilitatefloatingimpuritiesintheliquidalloy,gasdischargeandalloyfeeding.⑧Whenthebearingalloyispouredinto,shouldwattstirethecylindricalspraycooling.Atthesametime,flexibilityacetyleneweldingtorchbakingalloyliquidthanthesolidificationpartsfromundersolidificationpreventwattupperbodyaheadofsolidification.⑨thealloyiscompletelysolidified,thetemperaturedroppedbelow204℃stopwater,andremovalofthemold,beclean,lighthangingputintheovenat100°Corabout,andslowlycooledtoroomtemperature.单位名称:河南锡基合金材料有限公司单位地址:郑州市中原中路148号***行:中国***郑州陇西支行企业账户:261116502623企业网址:http://联系电话:0371-67670811/67670822移动电话:13938533129联系人:刘明志经理主营产品:高纯锡锭锡基合金轴承合金巴氏合金锡锑合金焊锡制品等。)
