H12MF Steel: caddaymaha, dib u eegista

wax soo saarka warshadaha ee saa'idka, qalab goynta iyo shaabadaysan waxaa loo sameeyaa iyadoo la isticmaalayo darajooyinka kala duwan ee birta. iyaga ka mid ah meel gaarka ah ayaa waxaa kujira H12MF steel.

Features of brand this waxaa sidoo kale mahad shirkado badan oo sameeyo alaabta gaar ah mindi. Maanta, wax this ka mid ah shirkadaha soo saarta aad loo jecel yahay, iyo sidoo kale ka mid ah purchasers kala duwan lagu cuno.

class fasalka

brand ugu weyn ee warshadaha injineernimada farsamada oo waxaa loo arkaa steel H12MF. sifooyinka Waxyaabaha kala duwan ka haray qalab carbonaceous dhigan heerarka sare cufnaanta qaab-dhismeedka. Noocan ah steel waa qalab fasal ku tuntay. Muddo dheer waxaa la isticmaalaa oo kaliya in wax soo saarka ee dhinto, waayo, foorarsiga iyo alaabta wax taaj oo kale. Tan iyo H12MF abuurtay steel waa heer sare adkaysi u saameyn jireed dibadda, waxaa loo adeegsanayaa in industry culus iyo warshadaha injineernimada.

Tani waa wax bir tayo sare leh oo ka kaas oo la sameeyey mindiyo ugaarsiga. Sida uu u eegista badan oo ka mid ah macaamiisha ku cad, waxyaabaha goynta sida waxaa ka mid ah xoog sare iyo tupyatsya dheer, taas oo muhiim u ah ugaadhsadaha. wax Faa'iidooyinka duubay by saarayaasha la isticmaalayo ee wax soo saarka H12MF steel.

guryaha

Faa'iidooyinka fasalka steel waxa ay kala yihiin:

• xoog sare;
• kululeeyo iska caabin ah;
• hardenability;
• quenchability;
• cimri dherer,
• processability.

hantida dambe waxaa la qiimeeyaa sayid H12MF steel machining. Sifooyinka brand ogolaan ay processing by yahay ee jarida nidaamka, cadaadis iyo ku shiidi.

alaabta

Mark H12MF in soo saaridda ee loo isticmaalo:

• takoorid rollers isagoo qaab kakan;
• dyroproshivnyh matrices adag, by hab oo bir sheet waxaa la aasaasay;
• marsho caadiga ah;
• diidanaa laadhuuga;
• portages;
• matrices;
• gacan qaad.

Maxaa siinayaa cufnaanta?

heerka sare, taas oo uu leeyahay H12MF bir ah, astaamaha ay calaamaddu ku taal waxaa lagu gaari by banaan jiid kabaha. Inta lagu guda jiro habka loo qaaday si loo farsameeyo baararka steel wareega kaalinta geeska gaar ah. Waxa la kululeeyo si heer kulka gaar ah. Intaas ka dib caskets H12MF mashiin baaraandegi isticmaalaya dubbe. Sidaas darteed, waa in ay qaataan bar a bir leh cufnaanta aad u dheer. Markaas waxaa mar kale la dhigayaa foornada oo sakhiray in daaweyn kululeeyo. Marka aaladda wax la filan kor u diiriyo, googooyaa yar yar.

Ka dibna, by baaraandegidda iyaga ku lifaaqan qaabka waslad doonayo. In sidan, mindiyo ay ka samaysan yihiin H12MF steel. Milkiilayaasha Reviews of garbaha sida badan waa qof wanaagsan, qaab-dhismeedka billet steel lagu jiro dubbe processing noqdo mid aad u qaro weyn, iyo this, markeeda, waxay bixisaa iska caabin sare si ay garbaha blunting.

Maxaad alloying xubno?

In qaabka asalka, wax bir caadiga ah waa daawaha ah ka kooban birta iyo carbon. Iyada oo ku xidhan hawlaha la qabanayo by sheyga, fuliyay isbeddel ah kiimikada ee daawaha, iyo this, markeeda, hagaajinaysaa iyo islana H12MF steel. Astaamaha (ratings xaqiijin warbixin) hagaagtay wax ku jira liiska soo socda:

• xoog sare;
• hagaagtay iska caabin ah daxalka,
• cimri dherer hawlgalka;
• awoodda goynta sare.

tayada Data H12MF keensataa dheer ee alloying xubno ku sugan. Nidaamka waxaa fuliyay in nidaam heerkulka gaar ah in ay la kulmaan lacagta loo baahan yahay ee Adkaan.

Qaab-dhismeedka

Mindi H12MF steel ka kooban oo ka mid ah ka dib markii xubno ka kiimikada:

• Chrome. Waxaa la soo bandhigay si loo horumariyo guryaha goynta iyo xirtaan iska caabin ah steels ah.
• Wolfram. element kiimikada Tani waxay wanaajisaa hardenability ah.
• Vanadium. Waa lagama maarmaan in tayo qaybiyey qaab dhismeedka of Qurub steel wajiga xad-dhaaf ah. Sababo la xiriira joogitaanka vanadium in sidiisa ku ool ah hoos u nuglaan kululaado. Marka qadar xad-dhaaf ah oo ah walaxda (in ka badan 5%) hoos guryaha caag ah waa in ay leeyihiin steel H12MF. Astaamaha (heysata saarka ratings steel si buuxda u xaqiijin) ee wax ku xiran tahay xaddiga vanadium. The yar joogitaanka element kiimikada, ka indices sare ee xoogga iyo ductility bir.
• Molybdenum. element kiimikada Tani waxay kor u soo hardenability iyo qalleyf bir. Isla mar ahaantaana ay joogaan xaddi badan oo daawaha molybdenum awood u hoos iska caabin ah si ay formation of burrs. Desirably, content oo ah walaxda in H12MF aan ka badnayn 1.7%.
• Manganese. element kiimikada Tani waa lagama maarmaan si loo yareeyo warping inta lagu jiro waxyaabaha adkaansho.
• Silicon. Waxaa loo adeegsaday si loo hagaajiyo iska caabin ah ay u tempering inta lagu jiro daaweynta kulaylka.

Warshadaha ee daawaha steel cadaadisay waa la fuliyay iyada oo la tixgelinayo shuruudaha martida.

H12MF: gaabiyey qiimaha

Decrypt steels adag. First of dhan, waa in aad ogaato xarfaha loo isticmaalo markay tixraacayaan xubno ka kiimikada. Si ay u muujiyaan chromium codsatay warqad X u, Ni - H, Cobalt - K, vanadium - F, molybdenum - M, titanium - C, copper - .. D, iwm Sidaa darteed, H12MF steel in ay ka kooban ee ku jira chromium, molybdenum iyo vanadium. tireedyada Tixraaca muujinaysaa content ugu weyn ee element alloying ah. Waxay waa chromium. 12% ka mid ah waxyaabaha kiimikada ka kooban H12MF bir ah.

sifooyinka

Mindiyo, soo sameeyey wax of brand this leeyihiin sifooyinka in la siiyo qaybaha steel ku jira dhexdeeda. Tan iyo H12MF waa bir carbon, badeecada Xaggeeda iska caabin ah ay xirtaan sare soo jireenka ah. Taas macnaheedu waa in geedku ka mid ah index carbon sare waxaa loo isticmaali karaa waqti dheer oo aan fiicneeyay. carbon 16% wuxuu qeexayaa oo waxay yeelan doonaan sifooyinka H12MF steel. Blades bir ah chromium (12%), ku dhawaad miridhku ku lahayn sameeyey. Haddii ay dhacdo in birta ku jira 14% chromium, waxa uu noqonayaa mid si buuxda u ahama. Joogitaanka xubno ka kiimikada bixisaa garbaha H12MF xogta ee xoogga iyo cimri dherer. Bixinta iska caabin abrasion waxaa suurtagal ah ay sabab u tahay dopant dheeraad ah. Ujeedada this, inta lagu guda jiro calcination H12MF daray molybdenum. Sidaas darteed, steel waa annealed isku. Mindi bay ka samaysan, waa wax soo saarka la fool direyska. Sida uu u eegista badan oo ka mid ah milkiilayaasha of garbaha kuwaas daliil, in qaab dhismeedka garbaha ku jiraan wax dhibco daciif ah.

imtixaanka mindi of H12MF

Test of mindi ugaarsiga steel waa wax soo saarka ah ee soo socda:

• Mindi dhigay rifling on xarig ah 200 mm. In opinion ee milkiilayaasha, geedku si fudud u samayn kartaa ugu yaraan saddex boqol oo rifling. Markaas waxaa loo arki doonaa in geedku beesho.
• Waayo, grooves waxaa sidoo kale loo isticmaalaa ulaha gudban ka lalmada. On this mindi wax aan ka badnayn boqol rifling ka dhigi kara.
• Waxaa dhimaysa wargeyska. Nuxurka ceelka imtixaanka tani waa si ay u tijaabiso macaamiloon ee mindi. Ujeedada this, geedku si tartiib ah hoos ka mid ah wargeyska page. Sida caadiga ah, xaashi si fudud jarjar laba inood u gaar ah sarkhaansan ay miisaan u gaar ah.

In kasta oo dhammaan faa'idoyinka H12MF steel, milkiilayaasha badan oo garbaha, kuwaas oo lagu talinayaa in ay u hoggaansamaan xeerarka laba:

• Tan iyo markii ay mindiyo ugaarsadaan ma yihiin hubka gantaalaha, tuur garbaha la jecel yahay in dhirta ama meelaha kale.
• Marna hubi garbaha u laabayso oo aan in aan xoojinno iyaga on.

Kuwa soo iibsatay mid ka mid ah kuwan mindiyo, khibrad ugaarsadaha talineynaa gacantaada ma lumin at qiraan jirridda. Sida ay macaamiisha badan, H12MF aad u xun loo qoray. Sidaas awgeed, mindidii bir ah brand ka dhigay marnaba dhalaalaya iftiimin doonaa.

Midabka caan ku seeftiisii - Matt. Marka tan la eego, mindiyo steel inta badan H12MF wareersan la barkimaheeda.
