Molten iron quantitative loading system and molten iron quantitative loading method

Abstract

The invention discloses a molten iron quantitative loading system and a molten iron quantitative loading method, and relates to a weighing device. Since the existing molten iron transport vehicle is composed of two groups of wheels in front and back, a molten iron tank for holding the molten iron is arranged between two groups of wheels, a group weighing modules arranged below the transport wheelsare used for weighing the transport vehicle so as to judge whether the molten iron is in quantitative loading, and the weighing module has a use condition for guaranteeing the normal use thereof, sothat the weighing module is prone to failure once the condition dissatisfies a use environment range of the weighing module in normal use (such as the molten iron overflows to the weighing module); and the problem that the weighing module is prone to failure is solved through the molten iron quantitative loading system disclosed by the invention. The technical scheme key point is that a control terminal computes the difference between weighing data MA of a first weighing device and weighing data MB of a second weighing device, and takes an absolute value of the difference, the absolute value is compared with the preset maximum error data, so that a worker can timely acquire whether the weighing of the molten iron is exactly correct; and the system is in favor of accurately and quantitatively loading the molten iron.

Description

technical field [0001] The invention relates to a weighing device, in particular to a quantitative loading system for molten iron and a quantitative loading method for molten iron. Background technique [0002] The current steelmaking steps first require ore and coke to enter the blast furnace for molten iron smelting, and then the molten iron passes through the converter or electric furnace for steelmaking, and between the two steps, according to the traditional process and circulation needs, it is shipped from the blast furnace through the molten iron car The incoming molten iron must be poured into the mixer furnace for heat preservation, component homogenization, and storage, while the molten iron used for converter steelmaking needs to be quantified by the weight determined by the steelmaking converter capacity formula on the molten iron vehicle scale on the side of the mixer furnace. Invert. [0003] For this reason, installing a track scale under the nozzle of the bl...

Problems solved by technology

[0004] The transportation of the above-mentioned molten iron is mainly realized by rail transport vehicles. The current transport vehicle 10' is composed of two groups of wheels before and after, and a molten iron tank for molten iron is arranged between the two groups of wheels. See Figure 5 The molten iron quantitative loading system weighs the transport vehicle 10' through a group of weighing modules installed under the wheels of the transport vehicle 10', so as to achieve the judgment of whether the transport vehicle carries out quantitative loading of molten iron. There are unfavorable environmental factors such as high temperature, smog, water vapor, and high groundwater level. What is more serious is that it is difficult to absolutely guarantee that molten iron leakage and overflow accidents will not occur at all. In the actual use process, the weighing module meets the conditions for its normal use. Therefore, once the conditions are not met, it is easy to cause the weighing module to fail, which will affect the accuracy of the weighing data measured by the weighing module or mislead the operator due to inaccurate weighing data. If the staff does not weigh, it is impossible to detect in time whether there is too much or too little molten iron through observation, so that it will affect the subsequent converter steelmaking, and there is still room for technological innovation and improvement
