Vanadium-titanium molten iron transferring one-can system technology

Abstract

The invention relates to the technical field of steelmaking and preparation, and discloses vanadium-titanium molten iron transferring one-can system technology. The technology comprises the followingsteps that 1) the waste of a steelmaking plant is used for refining a molten iron ladle, the net loading capacity of the molten iron ladle is 75-80 tons, a steel-making platform is purchased, a flat car is matched with an existing tractor for use, molten iron is directly conveyed to an old area for steelmaking after the molten iron is full of molten iron, the process of "adle turning" of the molten iron does not need to be carried out, and "one-can system" technology of the existing popularization is carried out; 2) the purchased flat car is modified, a molten iron ladle capping mechanism, a weighing mechanism and a brake mechanism are additionally arranged on the purchased flatcar, the molten iron ladle capping mechanism is obtained through simple modification by utilizing a mechanical arm, the bearing mechanism and the brake mechanism can be directly purchased, and the center distance 3620 of an iron can on the platform does not change. According to the vanadium-titanium molten irontransferring one-can system technology, the use of the molten iron can between an old-area blast furnace and an old-area steel-making process is facilitated, the purpose of higher improvement is achieved, and the modification technology is more convenient and simple.

Description

technical field [0001] The invention relates to the technical field of steelmaking and one-pot production, in particular to a one-pot production technology for vanadium-titanium molten iron transfer. Background technique [0002] Since the current iron-making ladle needs to be "turned over" before it can enter the steelmaking pretreatment process, according to the statistics of the molten iron temperature data from October to November ℃, the average temperature of molten iron is about 1295℃ after turning over the ladle to desulfurization stirring, the temperature drop of molten iron is about 42.5℃, the weight of single ladle of molten iron in blast furnace is between 35-40t, and the demand of single ladle converter for making steel is 73 Between -78t, after the hot metal is overturned, there will be residual iron or insufficient loading. Due to insufficient iron or insufficient loading, "one bag is not enough, two bags are more than enough". With the increase of blast furnac...

Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides a vanadium-titanium molten iron transfer one-pot technology, which has the advantage of higher transportation improvement and improvement, and solves the problem that the transportation improvement in the existing "one-pot" technology is not high enough. A large number of existing steelmaking plants in old areas are difficult to implement large-scale transformation operations of "one tank to the end". However, it is difficult to meet the higher transportation speed and total transportation volume by using the existing transportation equipment and means of transportation in steelmaking factories. steelmaking needs, and there are still many details that need to be improved in the existing methods
