Embodiment Construction

[0014] 1. Raw materials for the production of ceramic-lined composite steel pipes:

[0015] name Granularity (mesh) weight ratio Ferric oxide 200~300 65%~80% Aluminum powder 200~300 20%~30% Chromium trioxide 200~300 2%~4% Quartz sand 200~300 2%~4% Anhydrous Borax 200~300 2%~4%

[0016] 2. The ferric oxide powder is made of industrial iron-based waste. Among them, additives such as chromium trioxide, quartz sand, and borax effectively increase the melting temperature of the aluminothermic reaction, delay the solidification time of the ceramic layer, and fill the gap inside the ceramic layer to make the ceramic layer compact.

[0017] 3. Preparation method of ceramic-lined composite steel pipe:

[0018] (1) Ordinary steel pipe is used, and the inner wall of the pipe is cleaned.

[0019] (2) Batching, according to the requirements of 1, batching is carried out according to the weight ratio, and the amount of material is dosed ...

Abstract

The invention provides a preparation method for an aluminum-containing ceramic lined composite steel pipe and belongs to the technical field of material production. The preparation method comprises the steps that firstly, the pipe inner wall of a common steel pipe is cleaned; ferric oxide, chromic oxide, quartz, borax and cerium are mixed and prebaked into a mixture, and then the inner wall of the steel pipe is coated with the mixture; the steel pipe is put on a centrifuge with the rotating speed being 2000-5000 r / min to be rotated; and electric sparks are used for igniting materials on the inner wall of the steel pipe. According to the preparation method, a waste ferric oxide material of industrial production can be selected as the raw material, waste is fully utilized, accordingly, energy is saved and the environment is protected during production, and more importantly, by adoption of the preparation method, a product is easy to produce, and the formed product is high in rigidity and can be applied conveniently.

Description

technical field [0001] The invention relates to a ceramic-lined steel pipe manufacturing technology, belonging to the technical field of material production. [0002] technical background [0003] With the development of industrial technology, more and more iron-based wastes are produced in my country's iron and steel industry, and the country spends a lot of manpower, material and financial resources to deal with these wastes. Facing the current environmental situation, relevant enterprises are looking for various effective, environmentally friendly and economical solutions. [0004] However, the ceramic-lined composite steel pipe produced directly by thermite has defects such as rough ceramic surface and many internal pores. Selecting appropriate additives is one of the effective methods to solve this problem. [0005] However, the current ceramic-lined composite steel pipe cannot be widely used due to many factors, especially the industrial production and the strength and...
