Abstract
An integrated composite low-carbon high-aluminium stopper for conticasting steel features that its rod head has the residual carbon content about 8-15%, and contains scale graphite (5-10 wt.%), electro-corundam (75-85), light-burnt alumina (2-5), metallic Si-Al powder (2.5-5), liquid phenolic resin (5-10) and solid phenolic resin (0.4-0.7%). Its advantage is long service life.
Description
Technical field
The present invention relates to a kind of novel inorganic non-metallic refractory product, especially relate to the low-carbon (LC) high alumina matter integral composite stopper rod that in continuous casting steel machine is produced, uses.
Background technology
The stopper that uses in continuous casting steel machine is produced both at home and abroad all is made up of two portions usually as aluminium carbon integrated filler rod or aluminium carbon integrated composite stopper rod at present, i.e. stopper rod body and caput.Stopper rod body generally adopts the lower raw materials of price such as brown corundum, and caput adopts white fused alumina.But the common AL of caput
2O
3Content is no more than 80%, and reason is caput and excellent body AL
2O
3It is bigger that content differs, and causes the thermal expansivity of material own to differ also bigger, in production and use, is easy to generate the phenomenon that turns around.Because caput AL
2O
3How much being directly proportional with the work-ing life of stopper of content, therefore, the prior art stopper is generally lower work-ing life.
Summary of the invention
The present invention is for solving above-mentioned stopper low problem in work-ing life, a kind of improved stopper is provided, this stopper caput adopts low-carbon (LC), high alumina refractories to be composited, and the remaining carbon of whole caput is 8-15%, caput material as low-carbon (LC) high alumina matter integral composite stopper rod, its component (weight percent, as follows) be: crystalline flake graphite 5-10%, fused white corundum or electric smelting compact alumina 75-85%, calcined alumina 2-5%, metallic silicon power and metallic aluminium powder 2.5-5%, liquid phenolic resin 5-10%, solid phenolic resin 4-7 ‰.
Wherein, crystalline flake graphite is 5%, fused white corundum or electric smelting compact alumina 78%, calcined alumina 2%, metallic silicon power and metallic aluminium powder 4.5%, liquid phenolic resin 10%, solid phenolic resin 5 ‰.
Wherein, crystalline flake graphite is 9%, fused white corundum or electric smelting compact alumina 78.5%, calcined alumina 2.5%, metallic silicon power and metallic aluminium powder 4.6%, liquid phenolic resin 5%, solid phenolic resin 4 ‰.
Wherein, crystalline flake graphite is 6%, fused white corundum or electric smelting compact alumina 82%, calcined alumina 2%, metallic silicon power and metallic aluminium powder 4.5%, liquid phenolic resin 5%, solid phenolic resin 5 ‰.
Along with caput material AL

3The increase of content, caput and excellent body AL
2O
3It is bigger that content differs, and causes the thermal expansivity of material own to differ also bigger, in production and use, be easy to generate the phenomenon that turns around,, between excellent body and caput, add a transition section for overcoming this problem, it adopts the mixing raw material of excellent body and caput, and the proportioning of two kinds of material is 1 to 1.
