Dry anti-penetration castable to extend the life of the cathode liner has a positive effect. On the one hand can buffer the cathode carbon block uplift; the other hand can strengthen the bottom of the security
The ability to reduce the heat loss at the bottom of the tank and to increase the temperature of the cathode carbon block itself and to reduce the temperature gradient between the upper and lower sides of the cathode carbon block. Due to dry
Dry anti-penetration castable can be infiltrated with the electrolyte to produce a layer of 5 to 15 mm thick, dense glass-like kaolin barrier layer:
This barrier, on the one hand, prevents the electrolyte from continuing to penetrate the lower part and protect its lower part
The temperature of dry anti-penetration castable is not destroyed; the other hand, because the barrier layer with plasticity and particle layer has a certain compressibility, can effectively alleviate the furnace uplift,
Deformation of the tank shell and other issues. Therefore, in the aluminum furnace in the furnace process, it can be placed directly on the insulation brick, the compaction of the upper part of the upper directly placed.

Explosion-proof quick-drying castables can significantly improve the permeability of the lining made of unshaped refractories, prevent and prevent the lining from cracking or exploding during the baking process due to excessive internal vapor pressure! Explosion-proof quick-drying castable is designed to meet the heating furnace construction time is short, baking fast heating, long life and the requirements of the development of high-performance refractory castable, oven time of 2-4 days, and ordinary conventional refractory castable to be 9 -15 days compared to effectively save oven time and reduce the production cycle. The series of castable can be applied to various parts of industrial furnaces, has been in a number of steel mills at home and abroad on the successful use of the furnace, is a variety of furnace repair, large and small repair of the ideal material.

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.
