Rutilit - reliable protection for blast furnaces

Sachtleben has developed a special product for the metallurgical industry, in the form of Rutilit. Rutilit protects the blast-furnace hearth reliably and on a long-term basis against chemical and thermal attack from the hot charge. The "Rutilit family", a group of three products, each with a different titanium dioxide content, has been systematically developed for injection into the blast furnace via the tuyeres. Injection into the hearth is a more effective and cost-efficient solution than the old method of importing titanium-containing materials into the BF with the burden. At the same time, the availability for the first time ever of a synthetic source of titanium with a constant quality and in practically any quantity required is also a great advance.

The secret of this Sachtleben product's success is its composition: The extremely fine, synthetically produced Rutilit titanium sources consist primarily of titanium dioxide and iron oxide, which co-exist in the mineralogically favorable oxidic phase, significantly increasing reactivity compared to natural sources of titanium. The free titanium dioxide is reduced to titanium in the blast furnace by carbon or by silicon. Titanium nitrides and titanium carbonitrides - highly temperature-resistant compounds which are deposited from inside onto the lining of the blast furnace and there assure the rapid generation of a protective "skin", are formed from the metallic titanium and the carbon and nitrogen dissolved in the hot metal. And that's not all: Their fineness and rheological characteristics also make Rutilit products outstandingly suitable for pneumatic conveyance, thus permitting direct injection through the tuyeres directly into the hearth-wall zone.

The test phase at Hüttenwerke Krupp Mannesmann (HKM) has also disclosed a further advantage of this synthetic source of titanium: Rutilit has a positive effect on slag viscosity, improving rheology and reducing the titanium content of metallurgical sand as a result of the lower quantities of titanium-containing materials imported into the blast furnace.
