Refractory bricks the term brick refers to those elements that can successfully withstand the heat without suffering damage to its form, as well as cracks, it is to be understood, that this property is linked to the ceramics auque them nor can withstand temperature of infinite way. These elements has a long history that begins in Neolithic times until our days, being that the manufacturing process and its applications to varied widely, not so its components. At present these elements can be found in almost all applications where it is necessary to protect computers and personal the heat from furnaces barbecue up in special ships and engines of internal combustion ceramic protection plates commercially it can be found in three types of presentations: cements, mortars and bricks the implementation of these elementsas already was this very linked to furnaces in the steel industry which usually demand more of these elements since it is used as coating to prevent damage to the molten metal crucibles. Bricks as such has smooth faces, and they are very resistant to temperature and abrasion, its price tends to be higher than 10 times that of the conventional brick, it is often classified according to their composition into 4 groups; Those acids containing clay, silica and aluminum sulphate, are usually cheaper than the rest and while more silica are more resistant to metal. (A valuable related resource: Mining). The second classification makes those so-called basic consisting of manganese oxide are more resistant than the previous, but more expensive, we also neutrals that are elaborated by neutral elements such as magnesia. And those so-called special consisting of carbides and zirconium useful for its lubrication ability, eventually placed ceramic elements in all these mixtures in order to further improve the mechanical and thermal resistance of the Assembly. Manufacturing process usually starts with the grinding of the components, then is the damping, molds and baking them until calcined them, at temperatures ranging between 1300 and 1600 C then cools the brick of slowly to avoid cracks, it is important to note, that the process should be handled with care to prevent vitrification of the Silicon content since this brittleness to the brick, however in some cases seeks certain vitrification to also ensure a certain degree of impermeabilityYou can find it in different shapes and sizes but usually the tetrahedron of 24 x 11.5 x 7.1 installation and pairing them require to be carried out by specialized personnel since not all mortars are useful for this purpose, in virtue of which contain moisture, the same way that as it is evident is harmful and should be avoided at any thing in particular Jan. Time of the commissioning of the oven since it generates internal pressures, which could degenerate into cracks in refractory, is also necessary provision spaces conveniently located so that they can verify the process of thermal expansion without problem without drawbacks..
