Fiber-based anti-sticking aluminum quick repair material and manufacturing method thereof

Abstract

The invention relates to a fiber-based quick repair material and a manufacturing method, comprising the following steps: 1) mixing 15-35% of inorganic refractory fibers, 20-45% of silica fume, 2-15% of anti-sticking aluminum additive, 0-10% of % calcium hexaaluminate fine powder and 10-20% powdered inorganic salt are accurately weighed in turn; 2) After adding the mixer for dry mixing for 1-3 minutes, add distilled water or demineralized water at the proportion of 30-45%; 3) Continue to stir until the fiber-based mixture is uniform, without dry material, with a fine hand and good viscosity, and then the fiber-based quick repair material can be obtained. 4) The present invention can be used for experimental rapid repair, direct flame baking at 600°C to 800°C, and has excellent anti-sticking properties. Improve production efficiency and reduce production costs.

Description

technical field [0001] The invention relates to a fiber-based rapid repair material and a manufacturing method, which are applied to the rapid repair of aluminum water flow troughs and diverter plates, and belong to refractory materials for aluminum processing industry. Background technique [0002] At present, the aluminum water trough and the diverter plate will produce local damage and cracks during use. There are two main types of refractory repair materials, fused silica and bauxite-based refractory repair materials, but there are some defects. : [0003] (1) Fused silica refractory repair material: usually use fused silica particles and fine powder as the main raw material, supplemented by micro powder such as activated alumina micro powder, silica fume, calcium aluminate cement, and an appropriate amount of water after stirring for a certain period of time. ; Faster hardening, can only be used with the distribution, can not be stored for a long time. At the same tim...

Problems solved by technology

Because high-alumina bauxite raw materials have a large expansion coefficient and high impurity content, this type of repair material is prone to cracks when dry, and has poor anti-sticking aluminum performance; similarly, when the heating rate is fast, there is moisture that is difficult to discharge and causes bubbling and the problem of bursting

[0005] Since the above two types of refractory repair materials have defects such as long drying time, cracks, and bubbling in use, the inventors have actively worked on this type of product based on their rich practical experience and professional knowledge in the design and manufacture of such products for many years, and in conjunction with the application of theories. Research and innovation, in order to create a fiber-based anti-stick aluminum quick repair material and its manufacturing method to solve the above problems and make it more practical
