The bulk density was 1.87 g / cm, the apparent porosity was 36.9%, and the compressive strength and flexural strength were 11.3 MPa and 5 MPa, respectively(46 grit aluminum oxide). When building a new blast furnace, the above parts and the heat insulation layer of the furnace shell can also be used to build villages, which has high construction efficiency and good quality(white aluminium oxide super fine). Hot air stove, generally equipped with three.

The content of Al2O3 and SiO2 are more than 70% and less than 20%, respectively(brown fused alumina price). The operation procedure is to drill holes from the outside of the furnace shell when the blast furnace is out of air, insert a nozzle, and use a piston mud pump to press the paste-like refractory mud to fill the gap between the furnace shell and the brick lining and the brick village and the furnace charge(aluminum oxide blast media 60 grit). The gap between them forms a protective layer of the furnace lining.

The mud pressed by the umbrella-shaped nozzle is evenly distributed, and the repair effect is good without losing mud(white alumina). Kashima, Japan "Umbrella-shaped ceramic nozzle made of high-aluminum or silicon carbide material, can be left in the furnace lining repair layer after use without harmful effects(brown aluminium oxide 24 mesh). The refractory pressure feed used by this plant has a particle size composition of: 56% is greater than 1mm and 42% is less than 0.074mm.

That is, the furnace roof plug-in sprayer successfully developed by Nippon Steel Corporation's Kushi Iron and Steel Plant(black corundum), spray-repaired the No. 2 blast furnace that has been in operation for 6 years, and stopped the wind for 22h and sprayed for 5.5h. The liquid oil material was used for mixing and heated at 1000C for 3 hours(white fused alumina for refractory). After 500C heating and holding for 30min, the adhesion strength was 1.6MPa.

Blast furnace hot blast stove is one of the important auxiliary equipment of blast furnace(white fused alumina). It is a regenerative heat exchanger that can provide a certain temperature of hot air for the effective operation of the blast furnace, that is, it will blow into the blast furnace to help coke combustion air(white aluminum oxide grit). Heating from normal temperature to high temperature (about l200 ~ 1350C), the air volume should be sufficient, and the supply should be continuous.

Recently, one of the modernization contents of blast furnace ironmaking technology is the use of high air temperature technology, which is also one of the important conditions necessary for ironmaking production(white aluminum oxide). Therefore, each blast furnace needs to be equipped with 3-4 hot blast stoves in order to alternate heating and air supply(brown aluminum oxide sandblasting). Japan, Germany, the United States, Russia and other countries have adopted high-temperature hot-air stoves.

Therefore, raising the air temperature of hot blast stoves is always on the important agenda no matter at home or abroad(white corundum). Practical experience has shown that an increase in the temperature of the hot air can not only reduce the coke ratio, but also increase the amount of molten iron(low sodium white fused alumina). The scene shows that for every 100 ° C increase in wind temperature, the iron-to-coke ratio per ton can be reduced by about 20kg, and the output is increased by nearly 5%.

The average wind temperature is currently 1100 ~ 1200C, and the average air temperature of individual hot-air stoves has reached about 1350 ° C(pink corundum). The average wind temperature of hot-air stoves in China is relatively low, generally 1000 ~ 1100 ℃. The hot blast stove is a vertical cylindrical structure composed of a combustion chamber and a heat storage chamber(brown aluminum oxide 16 grit). Its height is generally 25-30m, and its diameter is generally 6-12m.
