Embodiment Construction

[0017] The present invention is described in detail below in conjunction with accompanying drawing:

[0018] As shown in Figure 1, a blast furnace is to a steelmaking workshop, in a working area composed of a steelmaking workshop 13 and a blast furnace 11, the blast furnace has three main trenches 10 and its iron trenches 9, three swing nozzles 8, two The straddle car operation line 1, two straddle car and railway mixed operation lines 2, one railway operation line 3, two receiving iron tanks 7 under each swing nozzle 8, and two straddle cars 6 are formed. On the side of the iron yard, the charging cross-factory building 4 of the steelmaking workshop is arranged next to the casting yard. The distance between the center of the blast furnace 11 and the center line of the charging span is less than 75 meters. Within the scope of work covered by the car 5; the receiving iron pot 7 used by the blast furnace 11 is placed on the over-span car 6 that can go straight and is equipped wi...

Abstract

The invention belongs to the technical field of the metallurgical industry, which discloses a compacted- type canning process of the blast furnace-converter interface, and a method for adjusting the production un-equilibrium between the blast furnace and the converter. In a steelmaking plant and an operating area where at least one blast furnace is comprised, the blast furnace is composed of at least a main ditch and an iron ditch thereof, a tilting trough, two running lines mixed of cross-train and the railway, a railway running line, two iron receiving tanks and two cross-trains, and the material charging bay of the steel making plant is laid out next to the cast house on one side of the blast furnace cast house; the cross-train adopts an electronic cross-train, and a weighing device is arranged on the cross-train. The method has advantages that hot metal temperature drop is better reduced, the energy consumption is further reduced, and the requred quantity of the iron receiving tank is also reduced; the measuring accuracy of the iron receiving tank is enhanced, thus the controlling for steel making process is stable; the areas of factory is reduced, the project investment is saved, and the method is suitable for an optimization design of the steel making and the steel making interface process engineering and the optimization of the general layout.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry, discloses a blast furnace-converter interface "compact one-pot manufacturing" process, and discloses a mediation method for buffering the unbalanced production between blast furnace and converter, especially suitable for ironmaking and steelmaking interface Optimal design of process technology and optimization of overall layout. Background technique [0002] BF-BOF interface "one-pot system" technology is a new technology for metallurgical process interface to achieve engineering optimization. It refers to canceling the traditional torpedo tanker or iron ladle between the blast furnace and converter interface to pour the cans and iron in the middle, and directly use the smelting The steel receiving iron tank realizes the process layout of multiple functions such as undertaking, transportation, buffer storage, molten iron pretreatment, converter ironing, container rapid turnover and...
