Introduction blast furnace clinker alumina bricks made of high quality clay as the main raw material, high pressure molding, high temperature sintering, the main mineral composition of mullite. Product has excellent physical properties and high temperature resistance to chemical attack, widely used in various parts of the small blast furnace lining. Physical indicators associated with high alumina bricks blast: Project ZGN42 GN42 AL203% of not less than min 42 42 fe2030% of not less than min 1.6 1.7 refractoriness load of not less than min 1760 1760 began softening temperature (RUL) of not less than min 1450 1430% Change heavy firing line (PLC) 1450 ° C * 2H 0-0.2 0-0.2 porosity% (AP) is not greater than (max) 15 16 Cold crushing strength MPa (CCS) is not less than min 58.8 49.0 steelmaking ladle is in the process of One of the important equipment. With the development of metallurgical technology for the design and use of the ladle lining work put forward higher requirements, and as a firebrick ladle working lining one of the main components. Ladle shell size parameters: maximum diameter steel catchy 4700mm, minimum 1985mm. Maximum diameter steel base 4300mm, minimum 1770mm. Steel maximum height 5040mm, minimum 2150mm. Lining the interior space of the size parameters catchy smallest maximum diameter 4460mm 1545mm; maximum base diameter 4060mm, 1360mm minimum free height 1000mm maximum minimum 200mm. Working lining structure: bottom bag is lined with 10 kinds of steel coated with insulating layer insulation layer thickest 80mm, the thinnest 10mm, the bottom of the bag is lined with 26 kinds of steel coated with security layer security layer, the thickness of 200mm, the thinnest 30mm; bottom lining Work thickest layer of 350mm, the thinnest 160mm; thickest impact zone at the bottom of the bag is lined 500mm, the thinnest 160mm; moreover wall clock ladle lining 15 with an insulating layer of insulation layer thickest 50mm, the thinnest 10mm; wall lining There are 26 kinds of steel coated with the thickest layer of the security layer security 150mm, the thinnest 30mm; wall lining work thickest layer of 220mm, the thinnest 110mm.
