Taiyuan Hlau Thiab Hlau Stainless Hlau thov rau patent

Taiyuan Hlau thiab Hlau Stainless Hlau thov rau patent rau martensitic stainless hlau hlau rods rau vuam.Pebxav muab ib co lus qhia txog nws hnub no.

Raws li kev tshaj tawm ntawm Tuam Tshoj National Intellectual Property Administration, Shanxi Taigang Stainless Steel Co., Ltd. tau thov rau ib txoj haujlwm hu ua "Txoj Kev Tsim Khoom ntawm ER135L Martensitic Stainless Steel Hlau Qws rau Vuam", tus lej luam tawm yog CN117139924A, thiab hnub thov yog lub Yim Hli 2023.

patent abstract qhia tau hais tias tam sim no invention nthuav tawm ib txoj kev ntau lawm rau vuam ER135L martensitic stainless hlau hlau rods, uas muaj xws li: xaiv ER135L martensitic stainless hlau billets raws li raw cov ntaub ntawv, cua sov rau lawv nyob rau hauv ib tug stepper cua sov rauv, cua sov thawj theem ntawm ib tug kub ntawm cov khoom. 950-1100 degree , cua sov theem thib ob ntawm qhov kub ntawm 1200-1260 degree , thiab soaking lub cua sov theem ntawm qhov kub ntawm 1200-1240 degree . Lub billet yog dov siv ob lub yob reversible billet qhib tshuab, thiab dov kub yog 1100-1200 degree, Dov rau hauv cov hlau puag ncig los ntawm 9 lossis 11 hla, ces nkag mus rau hauv high-speed hlau nruam dov zeb rau yob rau hauv coils, nrog ib tug hlau kos duab kub ntawm 1050-1150 degree . Tom qab xaim kos duab, nws yog tam sim ntawd txias los ntawm dej tsuag kom qis dua 50 degree ua ntej yuav dov rau hauv coils; Thawb lub kauj rau hauv qhov cub kho cua sov, nce qhov kub ntawm tus nqi ntawm 50-100 degree mus rau 640-660 degree, ua kom sov rau 4-6 teev, txias nws mus rau 400 degree nrog rau qhov cub , thiab tom qab ntawd cua txias tawm ntawm qhov cub rau 6-8 teev; Tom qab ntawd, ua kom sov lub kauj dua mus rau 640-660 degree, ua kom sov rau 4-6 teev, txias hauv qhov cub kom qis dua 400 degree, thiab tom qab ntawd tshem tawm ntawm lub qhov cub kom cua txias, tom qab ntawd ntxuav cov kua qaub. ntawm lub kauj. Cov hlau pas nrig uas ua los ntawm cov txheej txheem ntawm qhov kev tsim tawm tam sim no muaj cov qauv zoo li metallographic, siab ductility, zoo plasticity, thiab tsis tshua muaj zog tensile, ua tau raws li cov neeg siv khoom xav tau.
