Staggered mounting method of lower furnace shell and in-furnace equipment of air heating furnace

Abstract

The invention discloses a staggered mounting method of a lower furnace shell and in-furnace equipment of an air heating furnace, and belongs to the technical field of air heating furnace equipment mounting. The process of the method comprises the steps that a, a furnace shell bottom plate is mounted on a base; b, a first belt furnace shell is hoisted and is placed on the furnace shell bottom plate; c, the longitudinal and transverse center line of a grate is released on the furnace shell bottom plate, and marks are made on the first belt furnace shell and the furnace shell bottom plate; d, according to the marks, furnace bottom I steel and supporting columns are mounted; and e, the grate is mounted on the supporting columns, meanwhile, a second belt furnace shell is hoisted in place, and the first belt furnace shell and the furnace shell bottom plate are welded. By means of the whole mounting operation process, staggered mounting of the furnace shell and the equipment is achieved, andthe construction period is effectively shortened on the premise of guaranteeing the mounting precision of the equipment.

Description

technical field [0001] The invention relates to the technical field of installation of hot blast stove equipment, and more specifically, relates to a method for interlaced installation of the lower furnace shell of the hot blast stove and the equipment in the furnace. Background technique [0002] As the main equipment of the smelter, the hot blast stove is an equipment that integrates combustion and heat transfer, and occupies a pivotal position in the smelter. In the process of installation and construction of the lower part of the hot blast stove in the current technology, after the furnace shell of the hot blast stove is installed in advance, the internal equipment of the hot blast stove is installed in sequence, although this installation process can ensure that the subsequent installation of corresponding equipment inside the furnace shell Accuracy, but the whole construction period is relatively long, and the installation efficiency is low, so further improvement is n...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the overall construction period of the lower part of the hot blast stove is longer in the prior art, and to provide a method for interlaced installation of the lower furnace shell of the hot blast stove and the equipment in the furnace; the present invention will hoist the first belt furnace shell to the furnace shell After the bottom plate, release the vertical and horizontal centerlines and mark them, so as to facilitate the installation of I-beams, support columns and other components inside the furnace shell, and finally hoist the second furnace shell, and install the first The bottom plates are welded to realize the installation of the lower part of the hot blast stove. The whole installation operation process realizes the staggered installation of the furnace shell and the equipment, and effectively shortens the construction period under the premise of ensuring the installation accuracy of the equipment.
