Refractories for Working Lining

MGO, MGO-CaO and Forterite based dry masses

After the success of gunning/trowelling mixes, Beijing Lirr, being the first in China, developed MGO, MGO-CaO and forsterite based dry masses which are sucessfully selected by many steel mills in China including Jingtang Steel, Handan Steel, Baotou Steel and Benxi Steel.

This series of products are easy to install and dismantle after use and perform well with extended service life, which are highly appreciated by steel mills.

Carbon-free and environmental friendly dry masses

In order to solve the problem of toxic and irritating gases generation during installation and pre-firing and C as well as H pick up in secondary refining, carbon-free and environmental friendly dry mass was developed to replace traditional dry masses. The new product, which contains inorganic binder and sinter aid, does not generate toxic gases during installation and pre-firing which is environmental friendly and does not increase C or H content of steel which can meet the requirement for high grade steel production. As an innovative, high quality and green materials, the new dry mass is awarded by Beijing Municipal Government as "Product of Self-innovation".

This series of products had been widely used in more than ten steel mills in China including Jingtang Steel, Qianan Steel, Hanbao Steel with good performance.

Castable for permanent lining

The steel fibre reinforced ultra-low cement castables devloped and produced by Beijing Lirr are characterized with good flow ability, easy installation, good anti-spalling and thermal shock resistance, which can meet the needs for quick installation and circulation of tundish. The products also perform well on slag and molten steel corrosion and penetration as well as thermal and structural spalling resistance, which ensure long service life and safe steel casting.
