Embodiment 1

[0027] A kind of spherical crown roof masonry method of the present invention comprises the following steps:

[0028] (1) Erection of scaffolding in the furnace: Firstly, the furnace shell is inspected and laid out. According to the structural characteristics of the furnace shell, an equilateral octagonal scaffolding is erected along the furnace shell; vertical poles are gradually added to the expansion section of the furnace to form a corbel shape. ;

[0029] (2) Erection of the rain-proof shed on the furnace roof: set up scaffolding around the furnace roof, cover a layer of rain-proof tents along the scaffolding, and fix them; set up horizontal bars on the scaffolding outside the furnace roof and the scaffolding in the whole hall, and the horizontal bars are formed by the center of the furnace Set up radially, then cover the rainproof tent and fix it;

[0030] (3) Correction and masonry of arched bricks: the arched bricks of the furnace roof should be laid before installing...

Abstract

The invention discloses a method for building a spherical crown type furnace top by laying bricks. The method includes the following steps of firstly, establishing a scaffold in a hearth; secondly, correcting and laying skew blocks; thirdly, erecting a spherical crown type arch green body, wherein the arch green body is manufactured first, the arch green body is erected with the skew blocks as the positioning standard, and the arch green body is manufactured through the first step of calculating and lofting the arch green body, the second step of establishing the field for manufacturing the arch green body, the third step of manufacturing the arch green body, the fourth step of preassembling and refining the arch green body and the fifth step of manufacturing an installation positioning annular beam; fourthly, laying furnace top bricks; fifthly, detaching the furnace top arch green body, observing and analyzing sedimentation, laying clay thermal insulation bricks on the furnace top, and detaching the scaffold in the hearth. The method has the advantages of being capable of effectively controlling sedimentation of the furnace top, simple and rapid in construction, high in integrality and high in building accuracy.

Description

technical field [0001] The invention belongs to the masonry process in the field of metallurgy, and in particular relates to a spherical crown type furnace roof masonry method. Background technique [0002] Fluidized fluidized fluidized roasting furnace is the main thermal equipment for copper-zinc roasting and smelting. With the rapid development of international and domestic metallurgy, building materials, chemical industry, nonferrous metals and other industries, the design of large volume, high efficiency, energy saving and environmental protection fluidized fluidized roaster has become a new trend. development trend. With the further improvement of smelting technology, the rapid development of non-ferrous industry has brought new opportunities and challenges to furnace construction. In particular, the design span of the spherical crown roof of the fluidized roaster is large, and the masonry precision is high. In the existing technology, the traditional construction ...
