The series of High Temperatures Fired Slide Plates at top temperatures appearance the appearance
of top strength, acceptable abrasion attrition and accomplished thermal shock
resistance. The articles are the best best for ample and average sized ladles
and abide casting tundish. Our alternation of accelerate plates accursed at top
temperatures awning Al2O3-C based, Al2O3-ZrO2-C based and MGO-spinel based,
which can accommodated assorted needs of altered animate grades.
Skateboarding alternation high-temperature
accursed at top temperatures appearance that the top strength, acceptable bane
attrition and accomplished thermal shock attrition characteristics.High Temperatures Fired Slide Plates is the best best for ample and
medium-sized bail and CON-continuous casting tundish. The top temperature
battlefront skateboard alternation including aluminum carbon, alumina,
zirconia, based on C and magnesium spinel, to accommodated the assorted needs
of altered kinds of steel.

Ladle-Shroud are two
main direction of development of the long nozzle:
(A) without SiO2 long
nozzle developed. Of
Al2O3-C qualitylong outlet usually contain a certain number
of fused silica in order to improve the thermal shock
resistance. However, due tothe SiO2
and MnO or FeO reaction to generate low-melting-pointmaterial, thereby
reducing the anti-erosion and anti-erosion
properties of the materials. Therefore, in casting high-manganese
steel or high oxygen steel, developed the materialdoes
not contain SiO2 Al2O3-C. Compared to traditional Al2O3-C materials, the thermal
expansion coefficient of the material isrelatively
large, must be precisely controlled warm-up conditions.In
addition, the rational design of alumina particle
size distributionor add ZrO2-Mo to the stone and
the amount of low melting pointmaterials, improved
material thermal shock
resistance. Japan'sKawasaki Steel Chiba plant by
increasing the aluminum carbonoutlet C and
Al2O3 content, excluding the SiO2 and
metalpowder, long nozzle, the average life expectancy has increasedto 10
times, up to 22 times.
(2) baking the package and a number
of intermediate castingwith a long outlet. Such a
long outlet usually contain more graphiteand a certain
amount of fused silica material antioxidant and anti-erosion
performance is poor, but it can save time and
energy. The case of multi-tundish pouring, in order
to extend the life of the outlet of the preheating temperature
of at least 800 ℃.Domestic long
nozzle aluminum carbon and fused quartz, the life
of 4 to 6 furnace. Jointly developed by Wuhan Iron
andsteelmaking and Luoyang Institute of Refractories Researchbaking long
nozzle can be more than 7 furnace continuous
casting, the casting time of not less
than 5h. Three Wuhan Iron
and steel-making by the head of the long
nozzle material into adense type, intake changed along
the ring sewn into the air, the formation
of the chamber and each furnace in
use to replace arefractory protection pad and through
outsourcing steel, also has made good use of effects.
