Embodiment 1

[0028]Taking steel plant A as an example, there are two 1350m 3 There are 2 continuous casting machines in the blast furnace and steelmaking plant, among which 1# continuous casting machine casts an average of 32 furnaces in one casting, and 2# continuous casting machine casts an average of 30 furnaces in one casting. Calculate the number of torpedo tanks required by A steel plant T for 24h.

[0029] The method for calculating the number of torpedo tanks in this embodiment is:

[0030] (1) Using the attached figure 1 The analysis method for the operation process of torpedo tanks shown is to analyze the operation process of torpedo tanks in A steel plant, and it is concluded that the turnover path of torpedo tanks sent to the steelmaking plant is: blast furnace-transfer area-can dumping station-transfer area-blast furnace; The turnover path of the torpedo tanks sent to the cast iron machine is: blast furnace-transfer area-cast iron machine-transfer area-blast furnace.

Embodiment 2

[0062] On the basis of Example 1, it is set that the effective volume utilization factor of the blast furnace in Example 1 is changed from 2.2 to 2.0, and 2 continuous casting machines in the steelmaking plant work at the same time. Within 24 hours, 1# continuous casting machine casts 34 furnaces, 2 #Continuous casting machine casts 32 furnaces. Also use the attached figure 1 The analysis method of the operation process of the torpedo tank and the calculation method of the turnover period are shown to analyze the torpedo tank.

[0063] (1) Analyze the relationship between blast furnace iron production and continuous casting machine iron demand

[0064] Use blast furnace iron production formula of the present invention to calculate blast furnace iron production:

[0065] Q BF = Σ i = 1 N ...

Embodiment 3

[0078] On the basis of Example 1, it is set to change the effective volume utilization factor of the blast furnace in Example 1 from 2.2 to 2.0, and two continuous casting machines in the steelmaking plant work at the same time, wherein 1# continuous casting machine casts 32 furnaces, and 2# continuous casting machines The casting machine casts 30 furnaces. Also use the attached figure 1 The analysis method of the operation process of the torpedo tank and the calculation method of the turnover period are shown to analyze the torpedo tank.

[0079] (1) Analyze the relationship between blast furnace iron production and continuous casting machine iron demand

[0080] Utilize formula of the present invention to calculate blast furnace iron yield, as follows:

[0081]

[0082] Choose the metal recovery rate of converter to continuous casting machine to be 99%, iron-to-steel ratio is 88%, use formula of the present invention, calculate continuous casting machine to need iron am...

Abstract

The invention relates to a torpedo ladle quantity calculation method applied to steel and iron works and belongs to the technical field of torpedo ladle management control. The torpedo ladle quantity calculation method includes: parsing operation processes of torpedo ladles; acquiring operation time of each section of the flow process of the torpedo ladles; analyzing relation between iron production of a blast furnace and iron needing quantity of a continuous casting machine, wherein the torpedo ladle quantity calculation method is put forward under the condition that the iron production of the blast furnace is respectively greater than, less than and equal to the iron needing quantity of the continuous casting machine. Torpedo ladle quantity can be reasonably calculated, and reference can be supplied for iron-steel interface production organizations.

Description

technical field [0001] The invention relates to a method for calculating the quantity of torpedo tanks applied in iron and steel plants, and belongs to the technical field of management and control of torpedo tanks. Background technique [0002] As the carrier of molten iron transportation at the ironmaking-steelmaking interface, the torpedo tank plays the role of connection-matching, coordination-buffering for ironmaking and steelmaking, and its operating status is an important reflection of the operating efficiency of the iron-steelmaking interface system. Proposing a scientific and reasonable calculation method for the number of torpedo tanks is of great significance for reducing the temperature drop of molten iron and realizing the dynamic and orderly operation control of torpedo tanks. At present, there are few research results on the calculation method of the number of torpedo tanks: the literature "Operation Control of Torpedo Tanks" (Journal of Beijing University of ...
