Aluminium tooj dag thiab txhuas bronze kuj paub lus. Muaj qhov sib txawv loj ntawm cov xim ntawm ob, thiab lawv cov txheej txheem cov yam ntxwv thiab kev siv kuj txawv.
Aluminium tooj dag yog ib qho tshwj xeeb tooj dag (aluminium brass) tsim los ntawm kev ntxiv txhuas rau tooj liab-zinc alloy.
1. Kev siv cov txhuas tooj dag
Aluminium nyob rau hauv txhuas tooj dag tuaj yeem txhim kho lub zog thiab hardness ntawm tooj dag, txhim kho corrosion kuj nyob rau hauv cov huab cua, thiab txhuas tooj dag yog siv los tsim cov khoom tiv thaiv corrosion.
2. Cov yam ntxwv tseem ceeb ntawm txhuas tooj dag
Aluminium tooj dag muaj zog hnav tsis kam. Nws muaj lub zog siab, siab hardness thiab muaj zog tshuaj corrosion kuj. Muaj cov cuab yeej txiav tshuab kuj tseem ceeb dua. Lub seamless tooj liab raj kos los ntawm txhuas tooj dag yog mos thiab hnav-resistant. Aluminium tooj dag seamless raj yuav siv tau nyob rau hauv lub tshav kub exchangers thiab condensers, cryogenic piping, subsea thauj kav. Kev tsim cov nplooj ntawv, tuav, pas nrig, kav dej, qhov chaw casting, thiab lwm yam. Muaj 62 feem pua ~ 68 feem pua tooj liab, muaj zog yas, siv los tsim cov khoom siv siab, thiab lwm yam.
3. Txheej txheem cov yam ntxwv ntawm txhuas tooj dag
Cov txhuas tooj dag series yog qhov nyuaj, thiab qee qhov nyuaj aluminium tooj dag muaj peb thiab plaub alloying ntsiab xws li manganese, npib tsib xee, silicon, cobalt thiab arsenic. HAI66-6-3-2 thiab HAI61-4-3-1, uas muaj cov ntsiab lus alloying ntau dua, yog cov alloys muaj li ntawm rau lub ntsiab lus, thiab qee qhov ntawm cov txhuas tooj dag nrog cov kev ua haujlwm nyuaj yog muab los ntawm cov khoom tshwj xeeb zoo li casting alloys.
Aluminium bronze yog tooj liab-raws li alloy nrog txhuas ua lub ntsiab alloying. Nws yog ib qho txhuas bronze uas muaj hlau thiab manganese ntsiab lus thiab belongs rau high-lub zog tshav kub-resistant bronze.
1. Kev siv thiab cov yam ntxwv ntawm aluminium bronze
Cov ntsiab lus txhuas feem ntau tsis tshaj 11.5 feem pua, thiab qee zaum muaj cov nyiaj tsim nyog ntawm cov hlau, npib tsib xee, manganese thiab lwm cov ntsiab lus ntxiv los txhim kho kev ua tau zoo. Aluminium bronze tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nws lub zog yog siab dua li ntawm tin bronze, thiab nws qhov kev tiv thaiv kub kub oxidation kuj zoo dua. Nws muaj lub zog siab thiab zoo hnav tsis kam. Nws yog siv rau lub zog muaj zog screws, ceev, lub tes tsho tooj liab, sealing rings, thiab lwm yam., thiab hnav-tiv taus qhov chaw. Qhov tseem ceeb tshaj plaws feature yog nws zoo hnav tsis kam.
Aluminium bronze muaj lub zog siab, hardness thiab hnav tsis kam, thiab feem ntau yog siv los tsim cov iav blanks, xov thiab lwm yam. Aluminium bronze muaj kev tiv thaiv corrosion zoo, yog li nws tuaj yeem siv los tsim cov khoom tiv thaiv corrosion, xws li cov kiv cua, li qub, thiab lwm yam. Txhuas bronze tsis muaj qhov cuam tshuam thiab tuaj yeem siv los ua cov khoom siv tsis muaj teeb meem. Nws muaj zoo thermal conductivity thiab ruaj khov rigidity. Raws li cov khoom siv pwm, nws yuav tsis ua rau pwm sticking thiab khawb workpieces thaum stretching thiab dov stainless hlau phaj kub exchangers. Nws tau dhau los ua cov khoom pwm tshiab. Aluminium bronze muaj lub cim xeeb zoo thiab tau tsim los ua cov duab nco alloy. Tus nqi ntawm aluminium bronze alloy yog pheej yig, thiab nws tau dhau los ua ib feem ntawm cov khoom siv hlau kim, xws li hloov cov tin bronze, stainless hlau, nickel-based alloys, thiab lwm yam. tias nws tau dhau los ua neeg nyiam thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam pej xeem thiab tub rog.
2. txheej txheem yam ntxwv ntawm txhuas bronze
Aluminium bronze yog tsim nyog rau melting nyob rau hauv nruab nrab thiab lub hwj chim zaus coreless induction furnaces. Qhov teeb meem loj tshaj plaws thaum smelting nyob rau hauv lub hwj chim zaus cored induction rauv yog: Al, O, los yog A1, 0 yog ib qho yooj yim rau lo rau ntawm phab ntsa ntawm lub melting channel. Lub slag tsim los ntawm lwm cov oxides ua rau cov seem zoo ntawm cov yaj channel tsis tu ncua kom txog thaum tag nrho cov seem ntawm cov yaj yaj ywm raug thaiv tag nrho los ntawm cov slag.
Lub melting cua ntawm induction rauv yog yooj yim los tswj, thiab lub melting ceev yog ceev, uas yog conducive rau txo los yog txawm tsis txhob muaj kev pheej hmoo ntawm ib tug loj npaum li cas ntawm hydrogen nqus los ntawm cov yaj thiab tsim Al, O, uas yog ib qho nyuaj. kom tawm los ntawm melting. Txawm hais tias zoo heev Al, O tej zaum yuav muaj cov nyhuv ntawm refining crystallization, tab sis qhov kev puas tsuaj loj dua yog tias Al, O yuav dhau los ua qhov chaw ntawm lamellar pob txha puas lawm hauv cov khoom ua tiav.
