Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] In the embodiment, in the prior art, three steam turbines in a self-provided power plant supply steam with two parameters: the first pressure is 0.95MPa and the temperature is 260°C; the second is 2.1MPa and the temperature is 290°C; sintering waste heat power generation supplies a The steam pressure of two parameters is 1.2MPa and the temperature is 260°C; the steam extraction of CDQ power generation steam turbine supplies a steam pressure of 0.5MPa and a temperature of 220°C; the steelmaking converter of Example 1 (a steelmaking converter) and Example 2 The steelmaking converter (Hanbao converter) produces steam by itself, supplying a parameter of steam pressure of 1.3MPa and temperature of 260°C. The above four steam sources supply ironmaking, steelmaking, steel rolling and other production and domestic steam through three steam pipe networks of 2.1 MPa, 1.0MPa an...

Abstract

The invention relates to a parameter adjustment method of a system for supplying and recovering two types of steam in an iron and steel enterprise, and belongs to the technical field of steel making steam system parameter adjustment. According to the technical scheme, the method comprises the steps that steam is directly supplied to an RH furnace after passing through a gas overheating device; andin a converter steam pipe system supplying RH, the gas overheating device is installed to heat converter steam, and the converter steam is enabled to be quickly heated to change into dry steam overheated by 20 DEG C to 40 DEG C, and the dry steam is used for an RH furnace vacuum pump. RH vacuum pumping requirements are met, and the problem that impact is caused on a steam pipe system because therecovery flow of waste heat steam of steel making suddenly changes. The parameter adjustment method of the system for supplying and recovering two types of steam in the iron and steel enterprise has the beneficial effects that when the parameters, including the usage quantity and the recovery quantity, of steel making steam are high in fluctuation, it still can be guaranteed that the steel makingsteam is supplied and recovered stably, the quantity of recovered steam is increased at the same time, and the efficiency of energy comprehensive utilization is improved.

Description

technical field [0001] The invention relates to a parameter adjustment method of two kinds of steam supply and recovery systems in iron and steel enterprises, and belongs to the technical field of steelmaking steam system parameter adjustment. technical background [0002] In iron and steel enterprises, the furnace system needs steam with two parameters, which have high requirements on the stability of steam pressure and temperature; one requires steam parameters of 1.3-1.5MPa, between 210-240°C, for RH refining Furnace and RH vacuum refining furnace use and generate steam intermittently. The smelting cycle is 38min. During steelmaking production, the RH refining furnace uses and generates steam, so the pressure of the RH steam supply system fluctuates greatly, and the stability of the pressure cannot be guaranteed. It is difficult to realize the supply and recovery of waste heat steam. The other requires a steam parameter of 0.88-1.0MPa, between 210-240°C, which is used fo...
