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...

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] Such as figure 1 , 2 As shown, a quantitative loading system for molten iron disclosed in this embodiment includes a rail scale body 1, and the rail scale body 1 includes steel rails 2 that are arranged on both sides of the long side and are parallel to each other for the wheels of the transport vehicle 10' to run on. 2 is set without foundation pit, which can avoid the impact of a small amount of molten iron overflowing into the foundation pit and affecting the quantitative loading system of molten iron. Both sides of the two rails 2 are embedded with a number of weighing modules 3 for detecting the gravity of the wheels. Module 3 constitutes the first weighing device 4, and some weighing modules 3 on the other side of the two rails 2 constitute the second weighing device 5, and the weighing data of the first weighing device 4 is defined as M A , ...
