The Process flow of refractory castable

In the production of high-grade refractory castables, it is necessary to use premixed powder. Otherwise, a small amount of admixture, ultrafine powder and fiber and other externally, difficult to mix, resulting in its function is not stable, affecting the construction and use. After the preparation of various refractory raw materials, respectively, into the silo stand. The silo is divided into fixed and mobile two. Uncertain silos are overhead, all kinds of china refractory materials through the promotion machine was promoted to the bottom of the bunker machine, and then sent to the respective silo. There are electronic scales and furnishings under the silo, according to the production of refractory castable tacit than to carry out ingredients. Then, will be equipped with a good investment in the mandatory mixing machine mixing, mixing time is about 5min.

Mixed with a good refractory castable mixing material, from the mixing device into the sub-packaging into the sub-packaging equipment, the bottom of the facility with electronic scales, after weighing after bagging or packing, and finally sealed with a sealed bag or Cloth paper sealing mouth. And then shipped to the cargo hold, according to the name and grade were placed. The production line is three-dimensional homework, plant Xuan open, more facilities, a higher degree of automation, material quality is more stable; mobile silo placed in the plant floor, the material with a feeder and belt conveyor to the top of the silo, And sub-installed into the silo, can also be used crane loading.

The bottom of the silo is equipped with a scale or electronic scale ingredient, with a good material, with a belt machine or trolley into the hopper hopper, and then carry out the mixing, the remaining process with the former. The production line level of homework, covering more facilities, less active, but also to ensure the quality of materials. Refractory castable finished products, heavy materials, the quality of each bag is generally 30 ~ 50kg, light material per bag was 20 ~ 30kg, the error of ± 0.2kg. In the production of refractory castables, reference to steel or fluid binder, can be dispensed or shipped directly to the user, but must specify the guarantee period and the amount of clay and low iron and steel series of refractory castables, the steel is also divided Installed.

If the steel out of date, easy to swap. Such as during the 3-month retention period, should also be mixed. In the refractory castable ingredients before, should be subject to refractory materials, steel and other materials and other materials, to carry out chemical analysis and physical function of the inspection; broken after the fire-resistant aggregate and fine grinding of refractory powder, should carry out chemical Analysis, screening and precision inspection. Refractory castables produced by the tacit ratio, whenever the raw materials and production processes and other conditions have changed, the need to meet the technical requirements of the experiment before they can be produced; new varieties of refractory castable production, the tacit ratio should also be re-test; When the refractory castable is produced, it should be inspected for its grain gradation. If it does not meet the technical requirements, it should be controlled in time. The finished product of each batch of refractory castable shall be measured according to the technical requirements and the performance measures shall be carried out according to the warranty and construction skill requirements , Made to the user.

Chinafirebrick provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, Magnesia Carbon Brick, clay refractory bricks and other refractory.

Technological process of refractory castable

The production of refractory castables, it is important to say that the process of production lines and facilities. Refractory ramming material, refractory spray paint, refractory repair and refractory coating and other materials, and its production and refractory castable is basically the same. Refractory castable production process, some of the raw materials without crushing, can be used directly. For example, aluminum hollow ball, ceramsite, expansion of the perlite and industrial aluminum and so on. According to the production scale and raw material varieties and characteristics of the conditions, the selection of important facilities: crushing - jaw crusher there are three categories, the model to the proportion of the feed port, an important 250mm × 400mm and 600 mm × 400mm, production capacity of 5 ~ 20t / h. Used for large pieces of coarse crushing.
Crushing - refers to the refractory raw material after crushing and crushing, but also the preparation of pellets. The facilities are cone crusher, roller crusher and dry mill. Sieve - the particles will be crushed material according to the size of the grain composition of different particles. The facilities are fixed slanting sieve and electromagnetic picking sieve and so on. The former screening efficiency of 70% before and after the latter is generally more than 90%. Fine grinding - refers to the production of refractory powder. The main facilities are ball mill, tube mill and sensory mill, etc . premix - refers to the additive, admixture, binder and fine powder and all the powder or a mixture of several kinds of powder, so called premixed powder. The facilities are double helix cone agitator and so on. Ingredients are generally used in electronic, weighing standards; stirrer with a forced agitator, mixing material can be input sub-installed and then sub-installed, but also from the extruder at the exit directly packed into bags; In addition, there are vertical Promotion machines, belt conveyors and equipment vehicles and other facilities.
The production of refractory castables, the production of refractory aggregates and powder, soft clay and other raw materials, and firing the same as the china refractory brick, not the same as the refractory aggregate critical particle size, grading, so the need for sieve Points, promotion and other facilities, storage silos are also more. At the same time, the preparation of premixed powder, which is a special process.
Chinafirebrick provides refractory products, calcium silicate products, castable & mortar, fire brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, Magnesia Carbon Brick, clay refractory bricks and other refractory.
