Steel City Group Metallurgical Accessories Branch has obtained 2 new national patents
.
The two patents are "Preparation method of non-metallurgical alumina" and "High-speed iron pellet for converter steelmaking and preparation method thereof"
.
So far, the number of national patents obtained by the company has increased to 23
.
It is understood that the company's "preparation method of non-metallurgical alumina" is to use the melt reduction method to prepare the aluminum molten waste slag produced in the silicon-titanium iron alloy to produce metallurgical alumina, which can realize the comprehensive resource and harmless treatment of aluminum slag, and has a good environmental protection effect
.
"A kind of converter steelmaking high-speed iron pellets and preparation method thereof" is the use of steelmaking "enrichment sludge" to prepare high-speed iron pellets to replace scrap steel for converter steelmaking, and ultimately achieve the purpose of reducing steelmaking production costs, while realizing the reasonable recycling of iron-containing secondary resources, the product has the characteristics of
high strength, low pulverization rate and low cost.
Among them, "a kind of high-speed iron pellets for converter steelmaking and its preparation method" has been successfully converted to production in April 2013, with a cumulative production of 26,000 tons of sludge, which has become another economic growth point
of Gangcheng Group's metallurgical auxiliary materials branch.
