Refractory castables dense furnace kiln forge lining are divided into acidic, alkaline, and neutral castables according to their chemical resistance; they're divided into heavy castables and light castables according to their bulk viscosity; they're divided into aluminum silicate, magnesia, and magnesium chromium according to the accoutrements used Quality, corundum castables, etc. There are numerous types, and it's delicate to make a choice without clear pointers and operating temperatures. The following is about the correct selection of refractory castables :

 

Refractory castables have certain use positions and use conditions, which should be named according to the characteristics of the dense castable refractory furnace kiln forge lining. For illustration, high temperature resistant castables should be named for corridor reaching high-temperature dears, high-temperature resistant and passable castables should be named for corridor reaching high-temperature results, and castables monolithic refractories with strong resistance to chemical erosion of sediment should be used for corridor reaching sediment. High- strength and wear-resistant castables are used for corridor that are exposed to impact and disunion of colorful accoutrements, and castables with excellent thermal shock resistance are used for corridor with frequent temperature changes. The main conditions of use must be met when opting. 

 

The main use corridor of featherlight refractory castables are heat sequestration, lower cargo- bearing structure, lower furnace shell temperature, and reduce heat loss, so as to achieve energy- saving goods. 

 Consideration of the cost of refractory castables.

 

After deciding which refractory castable to choose, the cost should be reducedeconomically.However, when the castable can meet the working conditions, the castable with the use temperature lesser than 1600 ℃ isn't named; the wear-resistant part adopts high bauxite clinker as the main material to meet the In the case of abrasive conditions, If the use temperature is 1500 ℃. The main reason is that the price of refractory castables is priced according to the content of the main accoutrements used, and the price varies greatly. There's no need to ignore profitable conditions in order to seek advanced quality. Especially the corridor of diurnal wear and gash are particularly important to this demand. 
 

 

The corridor used for refractory castable construction are thick or thin, and the flyspeck size rates used are also different. For illustration, for stuffings with a consistence lesser than 100 mm, more large- grain summations need to be added to ameliorate structural strength and wear resistance. For pouring or smearing corridor with a consistence of 10 mm, use lower large- grain summations. Avoid adding The large total makes it bag from the filling body, which not only affects the appearance, but also the large patches are easy to wear in the use effect, which is easy to beget recesses in the filling body, which affects the service life. Pouring system or smearing system can be used for different pouring consistence, so the choice of the flyspeck size of refractory castable is also veritably important. 

The shelf life of refractory castables. 

 

Refractory castables can be stored for about 6-9 months in a dry state. Check whether there's agglomeration before use. During transportation or running, the dense castable refractory furnace kiln forge lining will wad due to the squeezing effect, and can be fluently discharged without affecting the use effect. In factual product, utmost of the castables are out of stock because of the different configuration processes of the castables. All need to produce according to the requirements of druggies and acclimate the product process. 

It can be seen from the above that the choice of refractory castables is changeable and should be usedflexibly.However, you must understand the specific use position, working condition, If you want to snappily and directly choose the castable you need. Only by chancing the right system can we choose high- quality refractory castables while reducing costs.
