Problems solved by technology

[0004] 1 The converter vaporization cooling system does not have the system function of sending steam to the external network and to the vacuum pump
[0005] 2. The process relationship between the steam drum and the heat accumulator in the traditional design prevents the converter vaporization cooling system from maximizing heat storage and reliably supplies steam to the vacuum pump
[0006] 3 The quality of self-produced steam for converter vaporization cooling is not good, which does not meet the requirements of vacuum pump steam
However, it is undoubtedly more difficult to additionally consider and solve these three problems in the already complicated vaporization cooling system

Abstract

The plant for using converter produced vapor in vacuum refining furnace pump includes three parts of a converter flue vaporizing and cooling system, a vacuum pump vapor pipeline and outward vapor feeding pipeline for the vaporizing and cooling system. The present invention features the new technological process of providing vapor to vacuum pump, and the technology has wide converage area and is especially suitable for adopting vacuum refining technology in converter steelworks.

Description

technical field [0001] The invention relates to the technology of converter vaporization cooling self-produced steam for vacuum pump of vacuum refining furnace. Background technique [0002] As we all know: in the steelmaking vacuum refining furnace device, the vacuum pump for making vacuum is the key equipment of the refining furnace. Vacuum pumps rely on steam for vacuuming. Vacuum pumps use steam in a strict system and have high requirements for steam quality. The steam consumption is a variable value, while the steam pressure is required to be stable. When the steam consumption changes, the pressure fluctuation must be eliminated within five seconds. Stabilize to the specified value, otherwise, the vacuum furnace cannot reach the required vacuum degree. Obviously, the steam source facility that supplies steam to the vacuum pump is a device that meets special requirements. [0003] At present, when domestic and foreign converter steelmaking manufacturers build vacuum re...
