Q195 Square Steel Yeeb Nkab
Hauv cov txheej txheem tsim khoom ntawm Q195 square steel kav, nws yog ib qho tseem ceeb los tswj cov tshuaj muaj pes tsawg leeg, suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S) qib, kom tau raws li qhov xav tau. cov qauv qhia. Cov txheej txheem yuav tsum tau ceev faj tswj cov pa oxygen thaum lub sij hawm steelmaking, nrog rau cov xim tshwj xeeb rau cov pa oxygen txoj hauj lwm thiab siab. Kev tswj slag kuj tseem ceeb, nrog rau kev tsom mus rau alkalinity thiab magnesium oxide cov ntsiab lus. Deoxidation thiab alloying yog cov kauj ruam tseem ceeb, qhov sib ntxiv ntawm cov ntsiab lus xws li silicon, manganese, thiab txhuas tau ua tib zoo ntsuas kom ntseeg tau tias cov khoom siv tshuab xav tau. Cov khoom kawg yuav tsum tau ua raws li cov qauv kev tswj xyuas nruj, suav nrog lub zog tensile thiab elongation, kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb.Q195 steel kav feem ntau raug rau cov txheej txheem kho cua sov xws li normalization thiab annealing los txhim kho lawv cov khoom siv kho tshuab. Normalization muaj cua sov cov hlau mus rau qhov kub thiab txias, tuav nws rau ib lub sijhawm, thiab tom qab ntawd txias hauv huab cua, uas tuaj yeem txhim kho qhov hardness thiab lub zog. Annealing, ntawm qhov tod tes, muaj cua sov cov hlau mus rau qhov kub siab dua, tuav nws, thiab tom qab ntawd txias nws maj mam, feem ntau hauv lub cub tawg, uas yuav pab txo qis kev ntxhov siab thiab txhim kho ductility thiab toughness. Cov txheej txheem no yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg ntawm Q195 steel kav, xws li lawv lub zog tawm los, lub zog tensile, thiab elongation. Qhov tshwj xeeb kub thiab sijhawm rau cov kev kho mob no tuaj yeem sib txawv raws li qhov xav tau thiab feem ntau txiav txim siab los ntawm kev sim cov khoom siv thiab kev ua kom zoo dua.
