  Il Couche isolante pour garnissages de fours tubulaires rota- tifs " 
Dans les fours tubulaires rotatifs sans enveloppe    en   pierres isolantes, la couche placée entre le garnissage ou maçonnerie intérieure et l'enveloppe ou chemise en tôle doit surtout satisfaire à la condition que, d'une part, elle assure une isolation convenable et que, d'autre part, elle tienne bien au métal et aux pierres ou briques du garnissage. 



   Ainsi que cela ressort d'essais, un mortier ou une masse à damèr ou comprimer de la constitution suivante con- vient particulièrement bien : 
Des parties en poids à peu près égales de farine de magnésite (magnésite concrétée ou magnésite caustique de 0 à environ   1,7mm)   et de la farine de chamotte (à peu près de la 

 <Desc/Clms Page number 2> 

 même grosseur de grains) mélangées intimement comme masse de base avec quelques pour-cent de sciure, de ciment Portland et de kieselguhr (ces deux derniers en grains de 0 à environ 0,3 mm) et avec une solution de verre soluble (silicate alca- lin). 



   Par exemple un mélange contenant des additions d'en- viron 4% de sciure, d'environ 2% de ciment Portland et d'envi- ron 1% de kieselguhr, le reste étant de la farine de magnésite concrétée et de la farine de chamotte en parties pratiquement égales présenta de très bonnes propriétés. Le mélange est gâ- ché d'une manière   connue   avec une solution de verre soluble. 



   REVENDICATIONS.

1. Couche isolante pour garnissages de fours tubu- laires rotatifs, consistant en parties en poids à peu près farine de/ égales de farine de magnésite et de/chamotte, et des addi- tions de quelques pour-cent de sciure et de ciment Portland ainsi que du verre soluble en solution.

  II Insulating layer for rotary tube furnace linings "
In rotary tube furnaces without an insulating stone casing, the layer placed between the interior lining or masonry and the sheet metal casing or jacket must above all satisfy the condition that, on the one hand, it provides suitable insulation and that, d on the other hand, it sticks well to the metal and to the stones or bricks of the lining.



   As is evident from tests, a mortar or a mass to be tamped or compressed of the following constitution is particularly suitable:
About equal parts by weight of magnesite flour (concreted magnesite or caustic magnesite 0 to about 1.7mm) and chamotte flour (about the

 <Desc / Clms Page number 2>

 same grain size) mixed intimately as a basic mass with a few percent sawdust, Portland cement and kieselguhr (the latter two in grains of 0 to about 0.3 mm) and with a solution of water glass (silicate alca - lin).



   For example a mixture containing additions of about 4% sawdust, about 2% Portland cement and about 1% kieselguhr, the remainder being solidified magnesite flour and flour. chamotte in practically equal parts exhibited very good properties. The mixture is mixed in a known manner with a water glass solution.



   CLAIMS.



   -----------------
1. Insulating layer for rotary tube furnace linings, consisting of roughly parts by weight of flour of magnesite and chamotte flour, and additions of a few percent sawdust and Portland cement as well as water glass in solution.
