Description
<Desc/Clms Page number 1>
pour : Procédé de fabrication de briques réfractaires
<Desc/Clms Page number 2>
ainsi qu'on le sit, des briques réfractaires et autres produits coraniques sont soûles en chamotte, maghésite concrétionée, quartz., corindon, ou dolomite calcinée, en y mélangeant les liants correspondants :
argile, magnésie, caustique, sable collant, etc... et en ajoutant les quantités d'eau nécessaire, après quoi on sèche et finalement on cuit dans des fomrs spéciaux, (Jette cuisson est très coûteuse, et nécessite environ un cinquibme de la quantité produite sous forme de combustible.
Conformément à la prosente invention, on a trouvé eue l'on peut réduire ou supprimer complètement cette cuisson coûteuse et ennuyeuse lorsqu'on utilise, comme liant pour les matières réfractaires ci-dessus, les scories sodiques obtenues dans les usines siderugiques lors de la de sulfurât ion. de la fon te brute.
On a constaté que déjà. quelques pour cent de scorie sodique, broyée seule ou avec des matières réfractaires, mélangée avec les matières réfractaires: chamotte, magnèsite concrétionnée, marine de silice, etc... suffisent pour faire durcir les briques ou autres objets moules obtenus par mélange avec un peu d'eau, au bout de quelques jours ou de quelques heures,dans une mesure telle que l'on puisse les transporter ou même les maçonner directement. Un leger chauffage à environ 100 accélère très fortement le durcissement.
Hais également dans la fabrication de blocs réfractaires particulièrement sensibles, dans lesquels une cuisson ultérieure est inévitable une faible addition de scorie sodique ou de scorie sodique broyée avec de la chamotte; de la magnesite, etc.. est très avantageuse, car les blocs obtenus présentent déjà au bout de très peu de temps des arrêtes résistantes et, par suite, sont facilement transportables.

for: Manufacturing process of refractory bricks
<Desc / Clms Page number 2>
as it is, refractory bricks and other Koranic products are made into chamotte, concretionated maghesite, quartz., corundum, or calcined dolomite, by mixing the corresponding binders:
clay, magnesia, caustic, sticky sand, etc ... and adding the necessary quantities of water, after which we dry and finally we cook in special methods, (This cooking is very expensive, and requires about a fifth of the quantity produced in the form of fuel.
In accordance with the present invention, it has been found that this costly and tiresome baking can be reduced or eliminated altogether when using as a binder for the above refractories, the sodium slag obtained in ironworks in the production. sulfurization. crude cheese.
It was found that already. a few percent of sodium slag, crushed alone or with refractory materials, mixed with the refractory materials: chamotte, concreted magnesite, marine silica, etc ... are sufficient to harden bricks or other molded objects obtained by mixing with a little of water, after a few days or a few hours, to such an extent that they can be transported or even directly bricked. A slight heating to about 100 greatly accelerates the hardening.
But also in the manufacture of particularly sensitive refractory blocks, in which subsequent firing is inevitable a small addition of sodium slag or sodium slag crushed with chamotte; magnesite, etc. .. is very advantageous, because the blocks obtained already have strong edges after a very short time and, therefore, are easily transportable.
