A return for the hot refining slag to the electric furnace as the raw material of the slag-forming agent is currently internationally recognized as the most low-costhigh-efficiency technology of choice for the removal of the refining slag waste. After years of research, our team has successfully developed an innovative green process for removal refining slag with high efficiencyhas conquered three major risksproblems that may arise from the refining slag returning to the electric furnace as a slag-making agent. At present, One steel mill in Taiwan has implemented this technologyhas achieved the forward-looking results of electric furnace smelting without refining slag by-products.

Our team has successfully developed an innovative green process for high-efficiency removal of slag,has mastered three core technologies (foaming, dephosphorization,desulfurization). First, we developed a technology that can produce a stable foaming slag for a long time without being affected by the slag component. Furthermore, the effect of the dephosphorization abilityits sulfur recovery rate with adding refining slag into the electric furnace is effectively improved. Finally, our team develop a desulfurizer with excellent desulfurization performance, the three core technologies can completely solve the three doubts caused by the addition of refining slag to the electric furnace.

This team has successfully developed an innovative green process for high-efficiency removal of refining slag, which has been implemented in Taiwan electric furnace steel plantshas successfully converted 100 refining slag waste into oxidized slag with high application value. Recycled pellets have been widely used to replace natural pellets. Compared with natural pellets, the carbon emission is about 39.5 kg/m3 less,it is 3/4 of natural pellets. This method can produce about 910,000 tons of recycled pellets for cement companies, saving 490 million dollars costreduce 30,000 tons of CO2 emissions, so it can ultimately achieve the goal of reducing carbon emissions, circular economy, waste removal.
