Cov ntaub ntawv tseem ceeb rau kev tsim cov tshuaj rammed txias yog: calcined anthracite, metallurgical coke, graphite hmoov, thee tar thiab thee tar ua binders. Lub qhov cub tuaj yeem ncaj qha rammed thiab ua rau ntawm chav tsev kub yam tsis muaj cua sov. Nws yog siv los sau qhov sib txawv ntawm carbon blocks. Tom qab ramming, ib qho tseem ceeb ntawm cov pa roj carbon ob sab yog tsim yam tsis muaj qhov sib txawv, uas tuaj yeem txo qhov hluav taws xob nkag mus rau qhov sib tsoo.
Txias ramming muab tshuaj txhuam yog tsuas yog siv nyob rau hauv aluminium txo cell, hlau ua moj tej tawg rauv, coreless induction rauv thiab submerged arc rauv.
Cov tshuaj ramming txias tuaj yeem muab faib ua kev sib koom ua ke thiab ua kom zoo sib koom ua ke raws li pawg particle thiab filling loj. Kev sib koom ua ke zoo yog siv los sau cov pa roj carbon ntau dua 2 hli, qhov sib xyaw ua ke feem ntau yog metallurgical coke hmoov tsawg dua 100 mesh, thiab cov coarse sib koom ua ke yog siv los sau qhov sib txawv loj thiab tamp rau hauv cov pa roj carbon monoxide.
Cov yam ntxwv tseem ceeb ntawm Cold ramming paste yog: me me coefficient ntawm thermal expansion thiab compact qauv tom qab masonry. Qhov me me porosity tuaj yeem ua rau cov electrode oxidize maj mam hauv lub tshav kub. Lub softening point yog tsawg thiab tuaj yeem ua ke nrog cov pa roj carbon block. Me me kuj coefficient yuav txo tau lub zog poob.
