News - Cold-Chunt Steel Steel: Thereay of Faterlial Standard

M'dongosolo lamakono la mafakitale, ma coils otentha achitsulo ndi zinthu zolimba, ndipo mitundu yawo yosiyanasiyana ndi kusiyana kwa magwiridwe ntchito mwachindunji zimakhudzanso kutsogolo kwa mafakitale otsika. Mitundu Yosiyanasiyana ya ma cold otenthetsera achitsulo omwe amagwira ntchito yosasinthika mu minda yomanga, mphamvu, ndi zina. Otsatirawa adzayang'ana kwambiri kusanthula mitundu yotentha yotentha yolimba ndi yofunika kwambiri pamsika komanso kusamvana kwawo.

Choyambirira chachikulu: Q235B ndi SS400
Q235B ndizomwe zimagwiritsidwa ntchito kwambiri kutsika-kaboni ku China, ndi zomwe zili ndi kaboni pafupifupi 0.12% -0.20%, ndipo ili ndi pulasitiki yabwino ndi yolowerera. Mphamvu zake zokolola ndi ≥2355MP ndipo imagwiritsidwa ntchito kwambiri pakumanga mafelemu, mlatho wa mlatho komanso zigawo zambiri. M'makampani omanga, i-mitanda, zitsulo zina ndi zitsulo zina zopangidwa ndi akaunti yoposa 60%, kuchirikiza mafupa a zomangamanga.
SS400 ndi chitsulo chapadziko lonse chopangidwa ndi q235b, koma chiwongolero cha sulfur ndi phosphorous ndi mawonekedwe abwinoko. M'munda wa zombo zopita ku SS400 zotentha zogulira zogubudukidwa nthawi zambiri zimagwiritsidwa ntchito ngati ziwalo zobisika. Kutsutsana kwake kwa madzi am'madzi kumali bwino kuposa chitsulo wamba kaboni wamba, kuonetsetsa chitetezo cha maulendo oyenda panyanja.

Kutentha kotentha kotentha - gulu lachifumu

Oyimira Mphamvu Kwambiri: Q345BD ndi Q960
Q345B ndi chitsulo chotsika kwambiri ndi 1.0% -1.6% manganese adawonjezera, ndipo mphamvu zokolola zili pamwamba pa 345MPA. Poyerekeza ndi Q235B, mphamvu zake zimachuluka pafupifupi 50%, ngakhale kukhalako kosatha. Mu Brid Engineerning, bokosi lam'manja lopangidwa ndi ma coils ofunda a Q345b owombera zitsulo amatha kuchepetsa thupi ndi 20%, ndikuchepetsa mtengo wamanja. Mu 2023, ntchito yomanga Briddle idzanyeketsa matabwa oposa 12 miliyoni a Q345B yotentha, yowerengera 45% ya zotulutsa zamtunduwu.
Monga choyimira wamba cha ultra-yayikulu chitsulo, q960 imakwaniritsa mphamvu ya ≥9600 ya £960MA kudzera muukadaulo wambiri (kuwonjezera vadium, Titanium ndi zinthu zina zowongolera. Pamunda wa makina opasili, makulidwe a msana wopangidwa ndi cholembera cha Q960 otentha amatha kuchepetsedwa kuposa 6mm, ndipo katundu wambiri amakula ndi matalala atatu, omwe amalimbikitsa kukweza kwa ma curcator ndi nkhata.

Chizindikiro Chapadera: Spoc ndi Sash340
Sphy ndi chinthu chomaliza pakati pa matebulo otsika ozizira. Pofuna kukonza njira yoyendetsa bwino kuti muchepetse kukula kwa tirigu, mkofuwo umafika 30%. M'makampani ogulitsa nyumba, makampani omenyedwa ndi spoc otentha amagwiritsidwa ntchito popanga mchere woponderezana. Zojambula zake zojambula zowoneka bwino zimatsimikizira kuti kuchuluka kwa mawonekedwe opindika kwambiri opindika 98%. Mu 2024, kugwiritsa ntchito ma coils a SPHC otentha ogubuduza panyumba m'munda wanyumba kumachuluka 15% chaka chimodzi mpaka matani matani 3.2 miliyoni.
Monga chitsulo chamagalimoto, mbalame340 imakwaniritsa bwino pakati pa mphamvu ndi kulimba powonjezera 0.15% -0.25% - kaboni kaboni. Popanga mafelemu atsopano a batri, masamba otentha owotcha amatha kupirira ndalama zopitilira 500mA ndikukwaniritsa njira zowonekera. Mu 2023, kuchuluka kwa mitengo yotentha yamtunduwu yomwe imagwiritsidwa ntchito munyumba yatsopano yamagetsi yafika 70% ya zigawo za batri.

Mtundu	Mphamvu (MPA)	Elongition (%)	Zochitika Zogwiritsa Ntchito
Q235B	≥235	≥26	Zomangamanga zomanga, makina a General
Q345B	≥35	≥21	Milatho, mitsempha yopanikizika
Sphyc	≥275	≥30	Zida zapakhomo, zigawo za auto
Q960	≥960	≥12	Makina azachipatala, zida zapamwamba kwambiri
