Reinforced hoop for vaporization cooling flue

Abstract

The invention provides a reinforced hoop for a vaporization cooling flue. The reinforced hoop comprises a shroud ring (2) and a hoop plate (7) which are vertically arranged on the outer surface of a flue (1) in a sleeving manner; each of the shroud ring (2) and the hoop plate (7) is formed by splicing four sector arc segments; the four arc segments of each of the shroud ring (2) and the hoop plate (7) are vertically and correspondingly distributed; every two adjacent arc segments are connected by an elastic assembly; outward-protruded hoop ears A (4) are vertically arranged on two sides of each segment of the shroud ring (2); outward-protruded hoop ears B (8) are vertically arranged on two sides of the bottom of each segment of the hoop plate (7); a round hole A (5) and a round hole B (9) are separately formed in the center of each hoop ear A (4) and the corresponding hoop ear B (8); a plurality of guide rings (3) are symmetrically distributed in the circumferential direction of the shroud ring (2); guiding shafts (6) matched with the guide rings (3) are symmetrically distributed in the circumferential direction of the hoop plate (7). The reinforced hoop provided by the invention can release radial deformation stress and axial deformation stress of the flue while the rigidity of the flue is enhanced; the reinforced hoop is simple to assemble and disassemble, and high in practicality.

Description

technical field [0001] The invention belongs to the field of strengthening structure of cooling flue, and in particular relates to a reinforcing hoop for vaporization cooling flue. Background technique [0002] Evaporative cooling flue is an important equipment in the cooling and dust removal system of converter steelmaking. It is an important part connecting converter and evaporative cooler. It has the functions of collecting, transporting, cooling and guiding flue gas. The evaporative cooling flue requires sufficient rigidity to maintain its structural shape during manufacture, transportation and installation. For this reason, reinforcing hoops are usually provided on the evaporative cooling flue to increase the strength of the evaporative cooling flue. The temperature of the vaporization cooling flue will rise sharply during the working process, which will cause the vaporization cooling flue to expand in the radial and axial directions. However, traditional reinforcement ...

AI Technical Summary

Problems solved by technology

The temperature of the vaporization cooling flue will rise sharply during the working process, which will cause the vaporization cooling flue to expand in the radial and axial directions. It is troublesome to disassemble and hinder the radial and axial expansion of the vaporization cooling flue, increasing its stress and accelerating the destruction of the flue
