ASTM A500 ndi ASTM A513Zonsezi ndi miyezo yopangira chitoliro chachitsulo pogwiritsa ntchito njira ya ERW.
Ngakhale kuti amagawana njira zina zopangira, amasiyana kwambiri m'njira zingapo.
Mtundu wa Chitsulo
ASTM A500: Mafotokozedwe Okhazikika a Machubu Opangidwa ndi Chitsulo cha Carbon Chozizira Chopangidwa ndi Wopanda Msoko mu Zozungulira ndi Mawonekedwe
ASTM A500 ikhoza kukhala chitsulo cha kaboni chokha.
ASTM A513: Mafotokozedwe Okhazikika a Machubu Opangidwa ndi Kaboni ndi Chitsulo Chosakanikirana ndi Magetsi
ASTM A513 ikhoza kukhala chitsulo cha kaboni kapena chitsulo cha alloy.
Kukula kwa Kukula
Njira Yopangira
Njira Yopangira ASTM A500
Chitolirocho chiyenera kupangidwa ndinjira yopanda msoko kapena yowotcherera.
Machubu olumikizidwa ayenera kupangidwa ndi chitsulo chopindika chopangidwa ndi chitsulo cholimba pogwiritsa ntchito njira yamagetsi yolimbana ndi kulumikiza (ERW).
A500 nthawi zambiri imapangidwa ndi chitsulo ikatenthedwa, kenako imapangidwa ndi kuzizira ndikuwotcherera.
Chidziwitso: Flat-rolled imatanthauza njira yopangira zitsulo yomwe imagwiritsidwa ntchito makamaka pa chitsulo ndi zinthu zina zachitsulo.Mu njira imeneyi, chitsulocho chimayamba mu mawonekedwe ake oyamba (monga ingot) ndipo chimaphwanyika kukhala mapepala kapena ma coil kudzera mu njira yotentha kapena yozizira yozungulira.
Njira Yopangira ASTM A513
Machubu ayenera kupangidwa pogwiritsa ntchito njira yolumikizira magetsi ndipo ayenera kupangidwa ndi chitsulo chotenthedwa kapena chozizira monga momwe zafotokozedwera.
Kutentha Chithandizo
Chithandizo cha Kutentha cha ASTM A500
Machubu omwe ali mu muyezo wa ASTM A500 nthawi zambiri safuna kutentha. Izi zili choncho chifukwa ASTM A500 cholinga chake makamaka ndi kugwiritsa ntchito kapangidwe kake, komwe cholinga chake chachikulu ndi kulimba ndi mphamvu zokwanira za kapangidwe kake. Machubu amenewa nthawi zambiri amapangidwa pogwiritsa ntchito kuzizira komanso kuwotcherera pambuyo pake, pogwiritsa ntchito chitsulo cha kaboni chomwe chili kale ndi mphamvu ndi kulimba.
Komabe, nthawi zina, kuti akwaniritse mawonekedwe enaake a makina kapena kukwaniritsa zofunikira zinazake zaukadaulo, machubu ndi mapaipi a ASTM A500 amatha kusinthidwa kapena kusinthidwa kuti achepetse kupsinjika, makamaka pamene kupsinjika kotsala kumachotsedwa pambuyo powotcherera.
Chithandizo cha Kutentha cha ASTM A513
Muyezo wa ASTM A513 umapereka mitundu ingapo ya mapaipi, ena mwa iwo amatha kutenthedwa ndi kutentha kuti akwaniritse mawonekedwe ofunikira a makina.
NA(Osati Annealed) - Osati annealed; amatanthauza chubu chachitsulo chomwe sichinatenthedwe kutentha mu mkhalidwe wolukidwa kapena kukokedwa, mwachitsanzo, chimasiyidwa mu mkhalidwe wake wakale pambuyo polukidwa kapena kukokedwa. Mankhwalawa amagwiritsidwa ntchito ngati palibe kusintha kwa mawonekedwe a makina komwe kumafunika pochiza kutentha.
SRA(Kuchepetsa Kupsinjika) - Kuchepetsa Kupsinjika; chithandizo chotenthetsera ichi chimachitika pa kutentha komwe kuli pansi pa kutentha kotsika kwa zinthuzo, cholinga chachikulu ndikuchotsa kupsinjika kwamkati komwe kumachitika panthawi yokonza chubu, motero kukonza kukhazikika kwa zinthuzo ndikuletsa kusintha kwa zinthuzo pambuyo pokonza. Kuchepetsa kupsinjika nthawi zambiri kumagwiritsidwa ntchito popanga zigawo zolondola kuti zitsimikizire kulondola kwa mawonekedwe ndi mawonekedwe.
N(Yokhazikika kapena Yokhazikika) - Kuphimba kwabwinobwino kapena kokhazikika; kutentha pa kutentha pamwamba pa kutentha kwakukulu kwa chinthucho komwe kungathandize kuti kukula kwa chitsulo kukhale bwino komanso kuti mphamvu zake ndi kulimba kwake ziwongoleredwe. Kuphimba kwabwinobwino ndi kutentha komwe kumagwiritsidwa ntchito powonjezera mphamvu zamakina za chinthucho kuti chikhale choyenera kwambiri pa ntchito zambiri.
Kapangidwe ka Mankhwala ndi Katundu wa Makina
Machubu a ASTM A500 adapangidwa kuti agwiritsidwe ntchito popanga zinthu ndipo ali ndi mphamvu zapadera zamakanika (mphamvu yokoka, mphamvu yotulutsa, kutalika) ndi mankhwala.
Imadziwika kuti ndi yolimba komanso yolimba ndipo ingagwiritsidwe ntchito m'nyumba zomwe zimafuna mphamvu zambiri poyerekeza ndi kulemera.
Pali mitundu yosiyanasiyana ya machubu a ASTM A513, iliyonse ili ndi mphamvu zake zamakaniko ndi mankhwala zomwe zimagwiritsidwa ntchito pa ntchito zinazake.
Mwachitsanzo, chubu cha Type 5 ndi chinthu chopangidwa ndi manja chokokedwa (DOM) chomwe chili ndi zolekerera zolimba, mawonekedwe abwino a pamwamba, komanso mawonekedwe okhazikika a makina.
Madera Ofunikira Kwambiri
ASTM A500 imagwiritsidwa ntchito kwambiri pa ntchito zomanga nyumba monga nyumba, milatho, ndi zinthu zothandizira. Imagwiritsidwa ntchito pamene pakufunika mphamvu zambiri komanso zomangamanga zolimba.
Koma ASTM A513 imagwiritsidwa ntchito pazinthu zomwe zimafuna kupirira kolondola kwambiri komanso kumaliza pamwamba. Ntchito zambiri zimaphatikizapo zida zamagalimoto ndi zida zamakanika zomwe zingafunike kuyikidwa pamodzi mwaluso kwambiri.
Mtengo
Zogulitsa za ASTM A500 nthawi zambiri zimakhala zotsika mtengo chifukwa cha kulondola kochepa kwa njira yopangira.
ASTM A513, makamaka Mtundu 5 (DOM), ikhoza kukhala yokwera mtengo chifukwa cha makina owonjezera omwe amafunikira kuti pakhale kulondola bwino komanso kumalizidwa bwino.
Chifukwa chake, kusankha pakati pa mitundu iwiriyi ya chitoliro chachitsulo kuyenera kutengera zosowa zenizeni za polojekitiyi.
Ngati pulojekitiyi ikufuna mphamvu ndi kulimba kwa kapangidwe kake, ASTM A500 ndi chisankho choyenera kwambiri. Pomwe, pa ntchito zomwe zimafuna kulondola kwambiri komanso mawonekedwe abwino a pamwamba, ASTM A513 ingakhale yabwino kwambiri.
Ma tag: ASTM a500 vs a513, astm a500, astm a513, chubu chachitsulo cha kaboni.
