1.Cold draw hlau
Cold drawn wire yog siv rau hauv cov khoom siv hauv tsev ntau zaus, thiab cov qauv kev ntsuas rau cov khaub thuas rub hlau kuj sib txawv.Lub zog ntawm cov khaub thuas rub hlau yog siab thiab nws tuaj yeem siv tau ntau txoj hauv kev. Feem ntau siv yog cov leeg pob txha prestressed.Qhov twg plasticity tsis tas yuav tsum tau, tab sis lub zog tsuas yog yuav tsum tau siv, xws li cov hlau tuaj yeem siv tau.Cold drawn wire yog hom hlau txias ua haujlwm.Cov khoom siv raw yog hlau qws, uas yog qhov peb feem ntau hu ua hlau. .Cov khoom tsim los ntawm cov txheej txheem ntau yam xws li shelling.Nws yog ib hom hlau.Ordinary round steel, yog tias nws raug yuam los ntawm ib lub qhov me dua nws txoj kab uas hla, txoj kab uas hla ntawm lub round steel yuav me dua thiab qhov ntev yuav elongated. Rov ua cov txheej txheem no yuav ua rau cov hlau puag ncig me me ntxiv. .Tom qab no cov yas deformation, lub hardness ntawm cov hlau yuav nce, thiab cov plasticity yuav pib ploj mus.
2.Annealed hlau
Annealed hlau muaj zoo elasticity thiab yooj, thiab nws softness thiab hardness yuav tswj tau thaum lub sij hawm annealing txheej txheem. Nws yog tsuas yog siv nyob rau hauv kev tsim kho kev lag luam raws li binding hlau thiab binding hlau.Nws yog softer thiab ntau saj zawg zog dua zoo tib yam dub hlau hlau, nrog uniform softness thiab uniform xim.Annealed hlau yog ib yam ntawm cov mos hlau hlau khoom ua los ntawm cov hlau tsis muaj carbon. txias kos duab, cua sov, qhov kub thiab txias, kev txuag hluav taws xob thiab lwm yam txheej txheem.Iron hlau muaj cov khoom sib txawv raws li kev siv sib txawv. Nws muaj hlau, cobalt, npib tsib xee, tooj liab, carbon, zinc, thiab lwm yam khoom.Yob lub kub hlau billet rau hauv a6.5mmthick steel pas nrig, uas yog ib tug hlau pas nrig, thiab ces muab tso rau hauv lub hlau nqus cov cuab yeej los kos cov xov hlau sib txawv. diameters, thiab maj mam txo txoj kab uas hla ntawm cov hlau kos duab reel, thiab ua cov txheej txheem xws li cua txias, annealing, txheej, thiab lwm yam. Craftsmanship ua rau ntau yam hlau hlau ntawm txawv specifications.
