Daim ntawv thov thiab cov yam ntxwv ntawm graphite sagger crucible

Crucible tuaj yeem siv rau kev siv cua sov ntawm ntau tus siv lead ua. Crucible tuaj yeem muab faib uagraphite cruciblethiabquartz crucible. Graphite crucible muaj thermal conductivity zoo thiab kub tsis kam; Nyob rau hauv daim ntawv thov kub, lub coefficient ntawm thermal expansion yog tsawg heev. Nws muaj zog strain resistance rau huab cua kub thiab txias. Nws yog resistant rau muaj zog acid thiab alkali. Nws yog tsim rau cua sov ntau yam kua; Ntxiv rau chemistry, graphite crucibles yog dav siv hauv metallurgy, casting, machinery, chemical kev lag luam thiab lwm yam departments; Lub graphite crucible yog ua los ntawm cov khoom siv graphite, uas tswj cov khoom siv hluav taws kub tshwj xeeb tshwj xeeb ntawm graphite. Lub graphite crucible feem ntau yog siv rau smelting non-ferrous hlau xws li tooj liab, txhuas thiab alloy. Muaj ntau ntau yam ntawm graphite crucible nws tus kheej. Ntawm no peb yuav luv luv sau ib lossis ob rau koj.
1. Cov pa phem tsawg dua, vim tias lub zog huv si xws li roj av lossis roj liquefied tuaj yeem siv los ua roj thiab muaj kuab paug tsawg.
2. Kev siv hluav taws xob tsawg, vim tias cov graphite crucible muaj kev npaj tsim nyog, cov qauv siab heev thiab cov ntaub ntawv tshiab. Tom qab kev sim, qhov kev siv hluav taws xob qis dua li ntawm tib hom rauv.
Resistance furnace siab purity graphite crucible yog tsuas yog siv rau smelting kub, nyiaj thiab tsis tshua muaj hlau.Ceramic cruciblesyog siv nyob rau hauv lub chaw soj nstuam thiab smelting ntawm platinum, kub thiab tsawg hlau. Lub graphite crucible puas tuaj yeem ua haujlwm ntawm qhov kub ntawm 2000 ℃ hauv qab cua txias? Nws puas yuav decompose thiab oxidize hnyav? Nws puas yuav carburize cov hlau molten? Qhov tseem ceeb tshaj plaws yog carburizing yog tuag taus. Raws li ib txwm muaj, nws tuaj yeem ncav cuag 2000 degrees hauv huab cua, tab sis nws yuav oxidize sai. Qhov teeb meem ntawm hlau carburization yuav tsum muaj. Tam sim no muaj cov txheej txheem tshwj xeeb los tiv thaiv carburizing ntawm lub khw, uas yog rumored kom muaj txiaj ntsig zoo.
