Problems solved by technology

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 technology has long construction period, high cost, poor masonry accuracy, short service life of the furnace body, and large furnace top settlement, which makes the ring joint between the top refractory bricks open, and SO2 appears on the furnace top after it is put into production. Gas leakage, harm to production and surrounding environment

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 ...
