Converter vaporization cooling flue

Abstract

The invention discloses a converter vaporization cooling flue. The converter vaporization cooling flue comprises a third flue segment (5) and a fourth flue segment (6), wherein the lower end of the third flue segment (5) and the lower end of the fourth flue segment (6) are respectively provided with water separator drainage tubes (1, 2); and the upper vapor accumulation zone of the third flue segment (5) and the upper vapor accumulation zone of the fourth flue segment (6) are respectively provided with vapor accumulation zone drainage tubes (3, 4). By adopting the above technical scheme, impurities in the third flue segment and the fourth flue segment which are the upper vapor accumulation zones of the flue can be well discharged, so the drainage effect of the flue is improved, no obstruction of the converter vaporization cooling flue is ensured, the failure rate of the flue is reduced, the production affected by the faults of the flue is avoided, the service life of the flue is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to a converter structure for iron and steel production. More specifically, the invention relates to a converter vaporization cooling flue. Background technique [0002] The blowdown of the vaporization cooling flue is mainly to use the blowdown pipe at the lower end of the flue to reduce the impurities in the flue through blowdown, reduce the failure rate of the flue, and prolong the service life. [0003] In the prior art, the third section and the fourth section of the flue only have the sewage discharge pipe of the lower end water distributor, which plays a certain role in reducing impurities in the flue. [0004] as in this manual figure 1 Shown: is a schematic diagram of the flue in the prior art; the water separator blowdown pipe 1 and the water separator blowdown pipe 2 are respectively the third section 5 of the flue and the lower end water separat...

AI Technical Summary

Problems solved by technology

[0006] 1. The blowdown of the converter vaporization cooling flue is only equipped with a blowdown point at the water distributor at the lower end of each section, and the blowdown effect is not good

The impurity discharge in the upper steam gathering area is not in place, and the impurity concentrates and falls into the pipe to cause blockage

[0007] 2. The failure rate of the cooling flue is high, the service life is shortened, the cost is increased and the production is affected
