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.
The main raw material of siliceous ramming material is silica, which is the general name of ganglite, quartzite and quartz sandstone.Acid refractory brick mainly used in metallurgical industry.Pure silica can be used as quartz glass or refined as monocrystalline silicon.In the chemical industry, it is used for the preparation of silicon compounds and silicates, and also as the filling material of sulfuric acid tower.Building materials industry for glass, ceramics, Portland cement and so on.
The advantages of silicon carbide refractory castable lie in its high heat conduction, low thermal expansion, and no reaction with slag. It has been used as slag reaction and high temperature peeling kiln site for a long time. The disadvantage of silicon carbide refractory is that the chemical properties are very unstable under certain atmosphere.In oxidation gases such as oxygen, water vapor, carbon monoxide, carbon dioxide) easy to corrode, iron oxide, etc, are easy to be in the hot metal and vacuum oxidation decomposition, the downside is that the refractory castable with carborundum dissolved water, in water system such as castable monolithic refractories, sometimes illiquid caused the density of silicon carbide refractory castable is bad, the third weakness is lack of sintering, hard to get high strength, but sometimes it is difficult to produce sintering and contraction, in monolithic refractories is a virtue.
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.
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.
The content of magnesium ramming material is above 84%, calcium oxide is controlled at 6%~8%, and ferric oxide is about 6%. Due to its high fire resistance, the service temperature reaches 1850~1950. With the use of superfine powder technology, make the material with high CaO magnesia and ultrafine iron oxide, can fully in the process of calcining synthetic reaction, generating distribution evenly throughout the material 2 calcium ferrite, and no obvious shrinkage phenomenon in the sintering process, ensuring the quality of the material of the sintering synthesis and improve the effect of the use of the material at the same time.After being sintered at 1600â?? for 3 hours, the compressive strength of the sample can reach 40~50MPa, which basically meets the compressive strength indexes required by nickel iron smelting.Therefore, after a certain temperature (not less than 1200â??), the material has high density, high compressive strength, good erosion resistance and volume stability. Magnesium ramming material is used in the bottom of the hot nickel iron furnace. Magnesium ramming material has good heat preservation and insulation property, which can reduce heat loss, improve furnace temperature, shorten smelting time and reduce smelting power consumption.The compactness of the forged furnace lining is good, which solves the local leakage phenomenon caused by the non-compactness of the formed magnesia brick masonry furnace lining. The use of magnesia ramming material to build the nickel-iron furnace has obviously improved the lining life cycle, reduced the consumption of refractory materials, and replaced the shaped materials with amorphous materials, which is over the water.
