Dab tsi yog txheej txheem ci ntawm refractory ramming khoom?

1. Ntxiv cov khoom: Tom qab knotted refractory ramming khoom, hlau yuav tsum tau ntxiv rau ci. Nws yuav tsum tau ntxiv cov qhob cij hlau. Sau lub qhov cub. Tsis txhob ntxiv oily hlau pins, hlau taum, los yog txhua yam hlau. Vim tias cov khoom siv refractory ramming ntawm lub qhov cub induction tsis yog sintered. Cov ntaub ntawv oily yuav tawm ntau cov pa luam yeeb thiab ammonia thaum rhuab ntawm qhov kub thiab txias. Tom qab kev kub siab, ntau cov pa luam yeeb thiab ammonia siab yuav muab tso rau hauv cov khoom siv refractory ramming, thiab tom qab ntawd tawm mus rau hauv lub qhov cub lub cev los ntawm cov khoom siv refractory ramming. Tom qab lub sijhawm ntev, yuav muaj ntau cov pa luam yeeb nyob hauv cov khoom siv refractory ramming, ua rau cov khoom siv refractory ramming dub. Cov nplaum nyob rau hauv cov khoom siv refractory ramming poob nws cov txiaj ntsig kev sib raug zoo thiab lub tshuab hluav taws xob hauv ob sab phlu yuav xoob. Muaj qhov tshwm sim ntawm qhov cub hnav. Yog tias muaj cov khoom siv roj hauv lub Hoobkas, nws tuaj yeem siv tom qab cov khoom siv refractory ramming yog sintered tag.

2. Pib lub induction melting rauv: khaws qhov kub ntawm qhov pib ntawm 0.2A tam sim no rau 20 feeb. Ci ntawm 0.3A rau 20 feeb. Ci ntawm 0.4A rau 20 feeb. Ci ntawm 0.5A rau 20 feeb. Ci ntawm 0.6A rau 40 feeb. Tom qab ntawd qhib rau qhov qub melting tam sim no. Sau lub cub tawg nrog molten hlau. Qhov kub nce mus rau 1500 degrees-1650 degrees. Cia nws sov li 60 feeb. Ci tiav lawm.

3. Kev ceev faj rau lub qhov cub txias pib: qhov cub txias pib. Pib nrog 0.2 rau 10 feeb. 0.3 thiab tos 10 feeb. 0.4 thiab tos 5 feeb. 0.5 thiab tos 5 feeb. 0.6 nyob rau 5 feeb. Ces nws ua haujlwm li qub.

4. Kev ceev faj rau qhov kub kub kaw: qhov cub kub kaw. Rau qhov kawg ntawm lub cub tawg, tsa lub qhov cub kub thiab ntxuav lub glaze nyob ib ncig ntawm lub qhov cub qhov ncauj. Cov hlau molten hauv qhov cub yuav tsum tau nchuav. Saib xyuas qhov xwm txheej ntawm lub qhov cub phab ntsa. Lub blackened ib feem ntawm lub qhov cub lub cev qhia tau hais tias lub cub tawg hauv ob sab phlu tau ua thinner. Ua tib zoo saib xyuas qhov no thaum koj qhib lub qhov cub rau lwm zaus. Npog lub qhov cub qhov cub nrog ib lub phaj hlau. Lub hauv ob sab yog maj mam luv.
