Mullite refractory castable general use of mullite aggregate to as raw materials and configuration of a kind of low temperature in the insulation refractories, it is commonly used in the petrochemical industry tube furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace and sulfur recovery device and steam boiler, tortoiseshell net heat insulation layer, two barrel and pipe insulation monolayer, and other industrial furnace door, see the fire hole, observation hole door lining, etc. The advantage of mullite refractory castable is that its refractory temperature is higher than other thermal insulation castable, which can be directly in contact with the flame and used as the lining of the kiln. Another kind of refractory castable is corundum mullite castable, which is a refractory castable prepared with corundum as aggregate and powder plus some binder.It has higher mechanical strength and abrasion resistance than high alumina refractory and Mullite refractory, but less thermal shock resistance.
HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance. HPMC has a thermal gel properties, after heating, the product solution formed the gel precipitation, dissolving after cooling. Different specifications products have different gel temperature. Solubility changes with viscosity's difference. The lower viscosity, the higher solubility, different specifications HPMC have difference in properties, dissolving HPMC in water won't be affected by PH value.
Steel fiber castable is widely used in high temperature vulnerable parts of metallurgy, building materials and circulating fluidized bed boilers.As follows: according to the classification of the material, it is suitable for planning the corundum quality before and after the steel fiber reinforced castable first used in large cement kiln kiln and other industrial kiln lining, high aluminum and corundum mullite stone steel fiber reinforced refractory castable first used in the cement kiln kiln mouth, wicket cover, before and after cooling machine in high temperature resistant parts and other industrial kiln liner.
Non-stick aluminum refractory castable or non-stick castable, the non-stick aluminum castable combines with the feature of inorganic binder, add a certain amount of insoluble in aluminium new composite refractory material, control the liquid aluminum erosion of refractory, non-stick aluminum castable with high volume density, high strength, not for the nature of the aluminum liquid wetting, can significantly reduce the corundum phase anomaly grew up and molten metal and permeability of materials.Suitable for the bottom of aluminum melting furnace, wall of furnace, slag-scraping slope, chute, aluminum water bag and degassing box, etc.
High alumina castable is a refractory castable made of high alumina raw material with binder and aggregate in traditional ratio.On the basis of the preparation of high strength and high aluminum castable, the granule gradation is adjusted, different admixtures are added, cement dosage is reduced, performance is improved, medium temperature strength and softening temperature under load are increased, thermal conductivity is reduced, and thermal stability is good.The furnace body structure integrity is strong, the air tightness is better than the brick furnace, extends the furnace life, saves the furnace repair cost, the economic benefit is remarkable as the high aluminum refractory castable characteristic.
The improvement of the performance of low cement casting material is actually the application of micro powder technology. There is a gap between the stability of low cement castable and that of laboratory castable.Low cement castable easy to occur problems are: 1, poor construction performance, poor liquidity;2. The hardening speed varies greatly, and there is quick setting or non-setting;3, easy to burst in baking;4. Abscission occurs;5. Low strength and poor wear resistance.These are caused by refractory castable products abnormal damage and other quality problems. Low cement refractory castable itself in addition to wear resistance, refractory aggregate, is used with good raw materials fine powder and ultrafine powder, cement and admixture, etc., through adjusting the proportion of each component, improve the high temperature performance of castable, thereby improve the strength of refractory castable. Low cement castable key construction, should pay attention to is: (1) do not arbitrarily increase the water content of refractory castable, (2) mold support set too high, leading to castable water content is too large and vibration compaction;(3) No mold shall be set during lining construction of feeding pipe, and castable material shall be manually daubed;(4) In order to save the mold, the maintenance is less than 48 h to remove the mold, resulting in the casting cracking or internal damage;(5) The material, shape, size, welding quality, quantity, anti-expansion treatment and unreasonable expansion joints of the anchoring parts;Do not follow the operational sequence of dry stirring, wet stirring and feeding, directly mix the dry and wet materials, resulting in the castable is not fully mixed evenly, part of the material is not wetted by water, making the castable has no strength. There are also key water issues, to use tap water, to avoid the introduction of acid and base impurities, gradually add, in order to make the dispersant in the powder to play a full role.Excessive water addition will directly lead to a significant decline in the strength of refractory castable construction, and in the field construction the water addition tends to exceed the degree of artesification.The pouring body itself is easy to appear when the ambient temperature rises rapidly, the baking burst, resulting in large area of damage.Once the temperature of the castable itself is below 5 the castable will still have no strength even after curing for 24 hours.The construction and maintenance shall be carried out in strict accordance with the 48-hour mold removal mechanism. In dry areas, water and wet maintenance shall be carried out; in cold areas, airtight heating maintenance shall be realized within 48-hour maintenance to ensure the maintenance temperature. In a word, if the above points can be achieved step by step in accordance with the requirements, it will certainly improve the performance of low cement casting.
Steel fiber has good tensile strength, strong grip strength and high hardness.If steel fiber is mixed in castable, the steel fiber castable products produced by this method are not only used, wear resistant, tensile and compressive, but also have a good anti-theft effect.And its adaptability and operational planning will be wider.It can be used at different temperatures.Greatly improved product utilization rate.So now large kilns, melting furnaces and so on will mostly choose steel fiber castable.Is to travel the quality of the product and use of life, compared to down, such a product more affordable. Steel fiber castable can reduce the shrinkage of castable during curing, grilling and high-temperature use. After adding steel fiber, not only the toughness of castable can be improved, but also the impact and mechanical strength of the machine can be improved.After adding steel fiber, the thermal shock performance of castable is improved.The steel fiber castable prevents fracture or spalling by preventing microcrack and mechanical stress. Steel fiber castable is widely used in high temperature vulnerable parts of metallurgy, building materials and circulating fluidized bed boilers.As follows: according to the classification of the material, it is suitable for planning the corundum quality before and after the steel fiber reinforced castable first used in large cement kiln kiln and other industrial kiln lining, high aluminum and corundum mullite stone steel fiber reinforced refractory castable first used in the cement kiln kiln mouth, wicket cover, before and after cooling machine in high temperature resistant parts and other industrial kiln liner.
