Embodiment

[0036] In the prior art, during the installation process of the lower part of the hot blast stove as a whole, in order to ensure the accuracy of the installation of various equipment inside the furnace shell, after the furnace shell of the hot blast stove is fixed and installed in advance, the various devices inside the furnace shell are installed. After the installation of the furnace shell is completed, the furnace shell is a whole, and its position will not change. Therefore, it is convenient for the operator to find the installation reference point when installing each device, so as to ensure the accuracy of the installation. However, due to the installation of the furnace shell After completion, the construction work area is limited and difficult to operate, resulting in a longer construction period.

[0037] In order to solve the above problems, a method for staggered installation of the lower furnace shell of the hot blast stove and the equipment in the furnace according...

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...
