Embodiment Construction

[0035] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0036] refer to figure 1 and figure 2 , the application provides a construction method for cast-in-furnace support formwork for intermediate repair of blast furnaces, the specific operation steps are as follows:

[0037] Step 1: Shut down the furnace and remove the tuyere middle sleeve; specifically, it also includes the transportation of the formwork material, and the formwork material is transported to the inside of the blast furnace after being removed from the position of the tuyere middle sleeve. Removing the middle sleeve of the tuyere not only facilitates the transportation of formwork materials, but also facilitates the entry and exit of staff.

Abstract

The invention provides an in-furnace pouring formwork construction method for medium repair of a blast furnace, which comprises the steps that the furnace is shut down, and a tuyere medium sleeve is dismantled; the charge level in the blast furnace is flattened, and a construction surface is pored below a mold in advance; the center of the blast furnace is obtained, vertical rods in the furnace are positioned with the center of the blast furnace as a datum point, and the vertical rods are arranged at preset intervals; a plurality of radian pipes are arranged to be in butt joint in the same plane to form a circular structure, and scaffolds are arranged to support all the radian pipes; in the vertical direction, a plurality of circular structures formed by the radian pipes are arranged at preset height intervals; laminated board construction is conducted, and battens are arranged between all laminated boards and the corresponding radian pipes; and after pouring and maintenance are completed, the scaffolds in the furnace and the radian pipes are dismantled and transported out of the furnace. The in-furnace pouring formwork construction method for the medium repair of the blast furnace provided by the invention has the advantages that the formwork erecting speed is high, the construction period is short, formwork erecting materials are convenient to transport, the structure after formwork erecting is stable and easy to adjust, and the method is suitable for medium repair of the blast furnace with the short construction period.

Description

technical field [0001] The invention belongs to the technical field of medium repair construction of blast furnaces, and in particular relates to a construction method for pouring formwork in a furnace. Background technique [0002] In the prior art, the blast furnace intermediate repair time interval is short and takes a long time, which seriously affects the output and economic benefits. Moreover, the blast furnace intermediate repair is indispensable, which will seriously affect the service life of the blast furnace. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method for constructing cast-in-furnace support formwork for medium repair of blast furnaces, so as to solve or overcome at least one technical problem existing in the prior art. [0004] The application provides a construction method for cast-in-furnace support formwork for intermediate repair of blast furnaces, including: [0005] Step 1. Shut down the...
