TUBOS A BASE DE OXIDO DE ALUMINIO Y PROCEDIMIENTO PARA SU FABRICACION. |
摘要 |
In a process for manufacturing gas-tight aluminium tubes suitable for carrying out catalytic high-temperature reactions, powdered aluminium oxide is mixed with water, a binder and a plasticizer, and the mixture is deformed by drawing a hank into a cylindrical green body, which is then deformed in at least two places so that the circular cross-section of the tube becomes approximately ellipsoidal. The deformed green body is dried and sintered at 1740 DEG C. Excellent mixing of the gas in the tube is achieved as a result of the constrictions in the cross-section.
