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 â??, 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.
High alumina low cement castable Corundum castable refractory Corundum refractory castable Refractory castable manufacturer Corundum castable refractory Corundum refractory castable Refractory castable manufacturer Al2o3: 90% Max service temperature c: 1750 Refractory castable: it is our bestseller. We can supply many kinds of refractory castable, such as low cement castable, self flowing castable, high alumina castable, mullite castable, azs castable, fireclay castable, light weight refractory castable, corundum castable refractory etc. The refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines, and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength. The refractory castable is primarily used fro furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and building etc. In plastic sheets and then in woven bags, last in wooden pallet
When It Was Determined That The Increase Of Highly Reactive Volatilized Or Fume Silica To A Castable Would Dramatically Change The Physical Characteristics, A New Family Of Castables Resulted. These Dense Durable Refractory Castables, Based On The Use Of Low Calcium Aluminate Cement Content, Have Replaced Many Conventional Castables, Plastics, Ramming And Gunning Mixes And Are Used In Many Applications That Require High Refractoriness, Corrosion Resistance, And Abrasion Resistance. These Castables Maintain A Stable Composition With Low Porosity And Have High-Temperature Strength Ultimately The Low And Moderate Temperature Range. Today Practically Every Refractory Castable Manufacturer Has A Complete Line Of These Low Cement Castables, Ultra-Low Cement, And No Cement Castables. These Low Cement-Type Castables Discover Many Applications Through Industry Including The Steel, Iron And Steel Foundries, Aluminum Furnaces And Other Non-Ferrous Metals, Rotary Kilns, Incinerators And Also For Making Precast Shapes. The Energy Which Is Developed In These Castables Is Often Equal To Or Greater Than Fired Products.

Low Moisture castables are essentially castable refractory requiring lesser amount of water for castings resulting in much denser product with superior mechanical properties as compared to conventional castable refractories. These contain lesser lime content and have much higher strength at metal melting temperatures as compared to conventional castable refractory. Hence these give better performance than normal castable refractories. 25kg/50 kg HDPE Bags with liners inside
