Kev lag luam steel ntawm cored hlau

Cov tub ntxhais hlau tuaj yeem ua tau zoo dua ntxiv cov khoom smelting rau molten steel lossis hlau thaum lub sij hawm steelmaking lossis casting txheej txheem. Los ntawm kev cob qhia cov khoom siv hlau, cov tub ntxhais hlau tuaj yeem muab tso rau hauv qhov chaw zoo tagnrho. Thaum qhov saum npoo ntawm cov tub ntxhais hlau melts, cov tub ntxhais tuaj yeem yaj tag nrho hauv txoj haujlwm zoo tshaj plaws thiab tsim cov tshuaj lom neeg, kom tsis txhob muaj kev cuam tshuam nrog huab cua thiab slag, txhim kho qhov nqus ntawm cov ntaub ntawv smelting. Nws yog dav siv los ua deoxidizer, desulfurizer Alloy additives tuaj yeem hloov cov morphology ntawm inclusions nyob rau hauv molten steel thiab zoo txhim kho qhov zoo ntawm steelmaking thiab casting khoom.
