Cov kev siv thev naus laus zis tshiab thiab cov txheej txheem tshiab ntawm kev ntxiv carburizing tus neeg sawv cev hauv kev tsim kho hlau yuav tsum yog zoo dua li cov ib txwm siv hauv cov nqi thiab cov yam ntxwv ntawm cov khoom. Ntxiv tus neeg sawv cev carburizing rau cov hlau smelting rauv, uas yog, siv tus neeg sawv cev zoo carburizing tuaj yeem siv los ua cov castings los ntawm cov hlau tsis zoo rau cov smelters. Yog li, peb yuav tsum ceev faj hauv kev siv cov carburizers.
1. Qhov kub siab graphitized carburizing tus neeg sawv cev, xws li graphite electrode lossis graphitized roj coke, yuav tsum siv cov kev lag luam kom deb li deb tau. Ua tus carburizer zoo, nws muaj ntau dua kev zom thiab sai dua nrawm nrawm, uas tau txais txiaj ntsig los txo cov kev siv zog, thiab tuaj yeem txhim kho nucleation tseem ceeb ntawm molten hlau thiab txhim kho kev lag luam metallurgical zoo.
2. Cov ntsiab lus nitrogen ntawm carburizer nrog cov ntsiab lus leej faj yog tseem siab. Thaum cov ntsiab lus nitrogen hauv grey hlau yaj yog siab dua qhov sib npaug ntawm qhov sib npaug, nws yooj yim heev los ua rau tawg zoo li N2 qhov, thaum lub grey hlau yaj yog qhov yooj yim ua rau shrinkage porosity hauv daim nyias-phab ntsa, thiab lub siab muaj qhov seem cov ntsiab lus tuaj yeem txhim kho qhov nyiam ntawm casting nugget.
3. Thaum xaiv, them sai sai rau qhov tseeb tias graphitized carburizing tus neeg sawv cev tom qab kev kho kub siab muaj cov khoom zoo. Yog tias nws tsis kuaj xyuas, koj tuaj yeem siv tus kov, saib lub qhov muag, thiab tseem tuaj yeem kos cov cim zoo heev rau ntawm daim ntawv.
