Abstract

The invention relates to a dismounting method of a hot-blast stove oven apparatus under restricted space. The method comprises the following steps: a temporary platform and an escape way are newly added, a temporary hoisting beam is newly added, and the oven apparatus is divided into five modules for dismounting in order. The temporary platform and the temporary hoisting beam are newly added, andthe oven apparatus is divided into five modules for dismounting, and the technical problem of dismounting of the oven apparatus under restricted space can be effectively solved, so that the method issafe and reliable.

Description

technical field [0001] The invention relates to the construction field of hot blast stoves, in particular to a method for dismantling an oven device of a hot blast stove in a confined space. Background technique [0002] The hot blast stove is one of the main supporting equipment of the blast furnace in the iron and steel plant, and its function is to continuously provide high-temperature hot air above 1000 °C for the blast furnace. In the renovation and new construction of modern hot blast stoves, the oven is an essential process. After the oven is completed, the oven device needs to be dismantled and restored quickly to provide a guarantee for the operation of the hot blast stove. Due to the large number of platforms and supports between the regenerator, combustion chamber and air mixing chamber of the hot blast stove, the space is limited, the oven device is large in size and heavy in weight, there are many safety hazards in the demolition process, and the construction t...
