【Product description】
Peb yog cov chaw tsim khoom uas muaj cov txheej txheem ua tiav ntawm mandrel cov khoom los ntawm cov khoom siv smelting, forging, kho cua sov, machining rau cov khoom tiav hauv Suav teb. Nws tuaj yeem tsim cov khoom lag luam zoo txwv, semi-floating thiab cov kev qhia tshwj xeeb ntawm cov tub ntxhais uas muaj dej ntws tag nrho yog 100 ~ 500mm inch.
Lub cev cov khoom lag luam qib zoo thiab cov khoom tsim muaj peev xwm yog nyob rau qib siab thoob ntiaj teb. Kev sib koom ua lag luam hauv tsev suav nrog ntau dua 60%, thiab nws raug xa tawm mus rau Is Nrias teb, Russia, Saudi Arabia, Tebchaws Asmeskas, Venezuela, Canada, Mexico, Argentina thiab lwm lub tebchaws. Lub mandrel yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws tsim nyog rau kev tsim cov kav dej loj loj seamless steel nrog cov cuab yeej siv niaj hnub no.
Cov khoom yog nyob rau hauv ib puag ncig hnyav thaum lub sij hawm dov txheej txheem ntawm seamless steel kav. Thaum lub sij hawm dov txheej txheem, nws yuav tsum tiv taus loj thiab complex stretching, Compressive contact stress thiab high-speed cycle high-temperature kub thiab txias qaug zog, yog li cov khoom no tso rau pem hauv ntej yuav tsum tau rau cov tshuaj muaj pes tsawg leeg, mechanical zog, non-metallic inclusions, grain. loj, microstructure, ultrasonic tsis pom kev, qhov tseeb qhov tseeb, roughness, thiab lwm yam. kev cai nruj.
【Txoj cai ua haujlwm ntawm seamless raj mandrel】
1. txheej txheem ib zawj nrog ib txoj kab uas hla ntawm 100mm thiab ib tug ntev ntawm 140mm nyob rau hauv pem hauv ntej ntawm lub mandrel. Qhov zawj no tseem ceeb heev rau cov txheej txheem yeeb nkab jacking. Rau jacking kav, qhov dawb paug siv los ua cov kav dej seamless yog rhuab mus rau 1150 degree ~ 1300 degree nyob rau hauv lub nplhaib rauv. Lub billet yog ib tug nruam nruam round billet nrog ib tug ntev ntawm 400mm ~ 1900mm thiab ib txoj kab uas hla ntawm 180 los yog 220mm. Lub round billet yog rhuab thiab xa mus rau ib tug peb-yob ntoo khaub lig-rolled yeeb nkab tshuab rau tho. Nyob rau lub sijhawm no, lub voj voog puag ncig yog dov thiab preformed rau ib qho tshwj xeeb sab hauv txoj kab uas hla thiab phab ntsa tuab los ntawm cov cuab yeej tshwj xeeb sab hauv (piv txwv li, lub ntsaws).
2. Nkag mus rau cov yeeb nkab dov tshuab, lub mandrel pib ua haujlwm. Lub mandrel yog preheated rau kwv yees li 450 degree thiab muab tso rau hauv lub hollow capillary raj. Lub raj rolling zeb ces ruaj lub hollow raj dawb paug ntawm lub aforementioned zawj nyob rau hauv lub ntsis ntawm lub mandrel. Nws tuaj yeem pom tias qhov tseem ceeb ntawm kev tsim khoom thiab kev ua haujlwm ntawm mandrel tseem ceeb npaum li cas.
3. Seamless yeeb nkab pib txheej txheem tseem ceeb hauv cov yeeb nkab jacking tshuab. Lub mandrel tau muab tso rau hauv lub raj capillary thiab tom qab ntawd thawb mus rau hauv ib txheej ntawm cov yob offset los ntawm 60 degree rau ib leeg rau dov. Nyob rau hauv no txoj kev, lub hollow raj dawb paug yog ua tiav rau hauv ib tug predetermined txheej kab uas hla thiab ib tug tshwj xeeb phab ntsa thickness, tsim ib tug raw raj. Nyob rau hauv lub tshuab deroding, lub mandrel yog loosened thiab sib cais los ntawm barren raj. Txij li thaum lub mandrel yog coated nrog ib tug non-metallic txheej raws li tau hais ua ntej, cov txheej txheem deroding yog ib qho yooj yim. Ua ntej lub mandrel rov nkag mus rau hauv cov txheej txheem, ib tug tshwj xeeb cais tus neeg sawv cev thiab lubricant yog siv rau saum npoo.
Lub #LimitingMandrel yog engineered siv cov khoom zoo H13 (4Cr5MoSiV1), paub txog nws lub zog tshwj xeeb thiab ua haujlwm ntev. Cov khoom no ua kom ntseeg tau tias peb cov mandrels tuaj yeem tiv taus qhov xav tau tshaj plaws thiab xa cov kev ua tau zoo ib yam thoob plaws hauv lawv lub neej ua haujlwm.
Nov yog cov ntsiab lus tseem ceeb thiab qhov ntau thiab tsawg ntawm peb #Limiting #Mandrel:
Khoom siv: H13 (4Cr5MoSiV1)
Txoj kab uas hla: 90mm-500mm
Ntev: Mus txog 18.5 meters
Txuas Xov Xwm: Ib feem Trapezoidal Xov
Txuj: API 5B
Peb cov mandrels yog tsim los nrog precision engineering cov txheej txheem los xyuas kom meej haum thiab seamless compatibility nrog koj cov khoom uas twb muaj lawm. Ib feem trapezoidal xov tsim ua kom yooj yim installation thiab tshem tawm, txuag koj lub sijhawm thiab kev siv zog thaum ua haujlwm.
Tsis tas li ntawd, peb Limiting Mandrel ua raws li API 5B tus qauv, lav nws txoj kev ua raws li cov kev cai ntawm kev lag luam thiab ua kom nws tsim nyog rau kev siv ntau yam kev lag luam.
Peb muaj kev txaus siab heev hauv peb txoj kev cog lus kom xa cov khoom zoo tshaj plaws thiab muab kev pabcuam zoo rau cov neeg siv khoom. Peb pab pawg kws tshaj lij yeej ib txwm muaj los teb cov lus nug lossis muab cov ntaub ntawv ntxiv uas koj xav tau.
