Manufacturing method of brick-steel composite assembly type self-standing steel chimney

Abstract

The invention relates to a manufacturing method of a brick-steel composite assembly type self-standing steel chimney, which comprises the following steps of: firstly, dividing the steel chimney into a plurality of cylindrical shell sections according to the manufacturing height of the steel chimney, and manufacturing a cylinder and a matched annular flange at the same time; circumferential flanges are welded at the upper end and the lower end of each cylindrical shell section; after the inner wall surface of the cylindrical shell section is cleaned, high-temperature-resistant anticorrosive primer is brushed; then borosilicate glass bricks are attached to form a single-section steel chimney of a brick-steel composite body; and finally, transporting to the field for assembly type installation to complete the manufacturing of the whole steel chimney. The method can give full play to the advantages of stable processing quality, convenient inspection, rapid batch production and the like of factories, can also respond rapidly according to application project requirements, reduces potential safety hazards of on-site high-altitude operation, and shortens the on-site construction period; technical implementation measures are provided for industry upgrading and social green development.

Description

technical field [0001] The invention relates to a method for manufacturing an assembled self-supporting steel chimney combined with brick and steel, and belongs to the technical field of chimney production. Background technique [0002] With the progress of society, the demand and field of industrial production, especially chemical production, continue to expand. Chimneys are an indispensable part of flue gas or exhaust gas emissions in industrial or chemical production processes, and the demand is also increasing with social development. As the flue gas or waste gas discharge chimneys of chemical enterprises, self-supporting steel chimneys are generally used. Because the flue gas emitted by chemical production or some other industrial production is often corrosive, it is generally necessary to add anti-corrosion and thermal insulation materials inside the steel chimney. The height of this type of steel chimney is generally below 120m, and the diameter is generally within 4...
