High Alumina Self Flowing Castable Application
 
1.Refractory castable high alumina self-flow widely used in metallurgy, building materials, petrochemical, electric power and other industries as lining.
 
2. Refractory castable high alumina self-flow widely used in blast furnace, hot blast stove, electric arc furnace, cement kiln, melting furnace, ignition furnace, flue, refining equipment, heating equipment and pipeline, regeneration thermal equipment
 
Refractory castable high alumina self-flow widely used in the gas furnace, soaking furnace, annealing furnace, thermal reaction chamber.
 
High Alumina Self Flowing Castable Manufacturing Process
 
1.Select the raw materials for the refractory high alumina self-flowing castable according to the formula and use.
 
2.The raw materials of the high alumina refractory self-flowing castables are proportioned,  the aggregate, powder particles and particle gradation are strictly controlled.
 
3.Stir the prepared powder first, then stir the aggregate, pour the powder into the aggregate and stir for 8-10 minutes.
 
4.The stirred self-flowing castable is packed into tons of bags and is equipped with additives and binders.
 
5.The packaged high alumina self-flowing refractory castables are stored in the warehouse, the date identification and moisture-proof waterproof treatment are done.
 
 High Alumina Self Flowing Castable Quality Factors Affecting
 
1. Reasonable aggregate granules and aggregate gradation. The refractory aggregate generally uses a spherical material with a low water absorption rate and a particle size of 5-8 mm. The ratio of aggregate to powder is 6:4, the ratio of coarse, medium and fine aggregate is 20:45:30.
 
2.High alumina self flow castable need suitable binders and water reducing agents. Use a reasonable binder and water reducer.
 
3.High alumina self flow castable need the right amount of water. Strictly control the amount of water, too much water can reduce viscosity and improve fluidity.
 
 High Alumina Self Flowing Castable Development
 
1.High aluminum self flowing refractory castable is a new type of refractory material developed in the 1990s. Compared with ordinary castables, high aluminum self flowing refractory castable not only inherits the high density of low cement castables, but also has the advantages of fire resistance, erosion resistance and wear resistance, and construction. The upper and lower sides do not need vibration equipment and flow freely, self-curing and compacting.
 
2.The high alumina self-flowing refractory castable has a fast construction speed and a long service life of the iron hook, which overcomes the defects of slow construction speed, poor quality of the iron hook and short life of the iron hook due to vibration.
 
High Alumina Self Flowing Castable Factors Affecting the Fluidity
 
1.High Alumina Self Flowing Castable Water Addition
 
The self-flowing castable is particularly sensitive to the amount of water added, the amount of water added is insufficient, the self-flow value is too small, the material cannot be filled normally, and the bubbles cannot be discharged; if the amount of water is too large, the aggregate will sink, resulting in separation of aggregate and mechanism. And too much moisture can damage the density and strength of the material, as well as erosion resistance and wear resistance.
 
2.High Alumina Self Flowing Castable The impact of Cement
 
Since the flow rate increases with the amount of cement, the water demand increases, the fluidity deteriorates, and the high temperature strength is unfavorable.
The amount of cement used is too small, and the medium temperature strength is low, so the amount of cement added is about 5%.
 
3.High Alumina Self Flowing Castable The Impact of White Mud
 
The addition of white mud replaces some of the special grade bauxite cylinder mill powder for fluidity, white mud as a bonding aid, drying strength and 1000 °C post-burning strength are significantly improved, and at high temperatures, white mud helps Molai The formation of stone improves the thermal shock stability.
 
4.High Alumina Self Flowing Castable The Effect of Ultrafine Powder
 
❉In low cement castables, silicon powder plays an important role. Refractory castable high alumina self-flow is beneficial to reduce the amount of water added and increase the hydration bond strength. The compressive strength is increased by increasing the amount of silicon powder.
 
❉High aluminum self flowing castables are a major breakthrough in refractory materials. They have good fluidity, and their physical and chemical indexes and performance are superior to other low-cement castables. They have popularized value and can be used as replacement products for vibrating materials.
 
❉The high aluminum self flowing castable has a good particle size composition, the fluidity becomes better as the coarse particle size increases.
