Embodiment Construction

[0029] It is mentioned in the related technology that when using a load cell to weigh the net weight of molten steel, driving the ladle to release or lift the ladle is likely to collide with the load cell or the connection line of the load cell, causing the load cell or its connection line to be damaged. The damage of the load cell will affect the accuracy of the measurement data of the load cell itself, and then seriously affect the accuracy of the measured net weight of molten steel.

[0030] In order to solve the above technical problems, the present application provides a method for measuring the net weight of molten steel in a ladle. figure 1 For the flow chart of the net weight measurement method of molten steel in the ladle of this application, such as figure 1 As shown, the measurement method includes:

[0031] In step s1, when the opening degree signal of the sliding opening of the ladle is received, timing is started to record the pouring time of the ladle. In this...

Abstract

The invention discloses a method for measuring the net weight of molten steel in a steel ladle. The method includes the steps that the pouring time of the steel ladle is recorded; the steel pulling speed of a steel pulling machine is detected to serve as the flow speed analog quantity of the poured molten steel; the width of a billet on the steel pulling machine is detected to serve as the width analog quantity of the poured molten steel, and the thickness of the billet on the steel pulling machine is detected to serve as the thickness analog quantity of the poured molten steel; and the net weight of the poured molten steel is calculated in real time according to the flow speed analog quantity, the width analog quantity and the thickness analog quantity of the poured molten steel, the pouring time and the density of the molten steel. By means of the method for measuring the net weight of the molten steel in the steel ladle, the problem that the net weight of the molten steel cannot beaccurately acquired under the condition that a weighing sensor is ineffective or the error is large is solved. Meanwhile, the method for measuring the net weight of the molten steel in the steel ladlemonitors the net weight of the poured molten steel in the steel ladle in real time, the accuracy of measured data of the net weight of the molten steel is guaranteed, stable operation of the site pouring technology is guaranteed, roughing slag of the molten steel is also avoided, the billet forming rate of the molten steel and the percent of pass of casting blanks are increased, and therefore economic benefits are increased.

Description

technical field [0001] The application relates to the technical field of iron and steel industry control, in particular to a method for measuring the net weight of molten steel in a ladle. Background technique [0002] In the production process of the continuous casting machine, the net weight value of molten steel in the ladle (hereinafter referred to as the net weight of molten steel) is a key parameter related to the smooth production of continuous casting. If the net weight of molten steel is severely distorted, it will affect the normal pouring of the continuous casting machine and the normal slag removal of the ladle. [0003] The net weight of molten steel generally refers to the total weight of molten steel used to make steel billets after the molten steel in the ladle is poured out. At present, the net weight of molten steel collected by the ladle weighing system is mostly used. The ladle weighing system includes at least 4 load cells, and the 4 load cells are resp...
