Tare da ci gaban tattalin arziki da kimiyya da fasaha, ingancin abubuwan da ake buƙata na samfuran extruded sun fi girma kuma sun fi girma, kuma an gabatar da wasu buƙatu na musamman a wasu fannoni, waɗanda ke haɓaka haɓakar saurin haɓakar samfuran.takardar tagullabaya extrusion fasaha.
An ɓullo da wani sabon nau'in reverse extrusion tsari na tagulla takardar dace da daban-daban karafa da gami da sauran karafa da aka ɓullo da.Bisa ga bukatar, tsarin tagulla takardar extruder ne kullum ƙirƙira da kuma inganta, da kuma sabon reverse extruder da daban-daban amfani da daban-daban Tsarin da aka ɓullo da.Dangane da buƙatun fasahar samarwa da ingancin samfurin, ana haɓaka mutuwa da sabbin kayan aikin extrusion na baya extruder tare da sabon tsari.
Babban ka'idoji na zaɓi na takardar tagulla na baya da fasaha na fasaha: (1) bisa ga halayen haɓakar haɓakar ƙarfe daban-daban, waɗanda kayan ya kamata a yi la'akari da su don amfani da juzu'i za a iya ƙaddara.Misali, a cikin juzu'in extrusion na jan karfe, tagulla da sauran allurai, motsin karfe yana tsakanin nau'in A da nau'in B, kuma canjin yanayin zafi da matsa lamba a cikin aikin extrusion yana da yawa.Yana da amfani don inganta uniformity na microstructure da kaddarorin extruded kayayyakin ta amfani da lebur mutu unlubricated baya extrusion na tagulla takardar da jan karfe gami waya, mashaya, profile da bututu.
(2) Yanayin gogayya na waje yana da tasiri a fili akan kwararar takardar tagulla.Yanayin juzu'i daban-daban na waje zai haifar da nau'ikan kwararar ƙarfe daban-daban.Sabili da haka, don kayan da ake buƙatar lubricated da extruded, yana da amfani don amfani da baya extrusion.
(3) Reverse extrusion dace da extrusion samar da tagulla takardar da high daidaici, lafiya tsarin da babu m crystal zobe da kunkuntar extrusion zafin jiki kewayon.Ƙarfin da ke aiki da ƙarfe yayin jujjuyawar baya, da kuma ƙarfin da ke aiki akan ƙarfe yayin jujjuyawar tsiron tagulla, babu wani motsi na dangi tsakanin billet ɗin ƙarfe da takardar extrusion.
