The use of refractory cement in boiler construction is also very large, and refractory cement is also a refractory castable that we need most. Refractory cement is also called aluminate cement. The raw material of aluminate cement is bauxite and limestone. It is made of calcined, with calcium aluminate as the main component, clinker with alumina content of about 50%, and then ground into hydraulic cementitious material, which is also a kind of special cement. The thermal stability of refractory cement is good. The aggregate is almost all clinker. The expansion and the shrinkage of the cement are low. Therefore, the thermal expansion of the masonry is smaller than that of the brick, the temperature stress is relatively small, and the structure is also various. Reticulated, needle-like, chain-like crystalline phase, strong resistance to air temperature, for example, used to cast soaking furnace mouth and furnace cover, the furnace age can be extended to one and a half years; and the fire resistance of refractory bricks and the same The texture of the refractory brick is similar, but because the refractory cement does not have a net more sintering, the initial blasting shrinks larger, so the load softening point is slightly lower than the refractory brick, but as a whole, the refractory cement is still due to the refractory brick.

refractory castable Casting is a kind of refractory material made of granular and powdery material, and add a certain amount of binder and water together. It has a high mobility, suitable for casting construction, and no need to heat can be hardened unshaped refractory.z

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.
