Description

Slag automatic stirring device {AN APPARATUS FOR AUTOMATICALLY AGITATING SLAG}

The present invention relates to an automatic stirring device for preparing a working-STD & House Sample by mixing slag, and more specifically, to easily mix the slag of a specific concentration, so that the standard sample can be easily prepared. It is possible to secure the manufacturing capacity of the standard sample, thereby eliminating the need to purchase the standard sample (P-STD), reducing the cost of purchasing the standard sample, and calculating the data of various target components. The present invention relates to an automatic slag stirrer that can improve the accuracy of analysis.

In general, steel mills analyze slag generated in steel making and steel making processes by XRF analysis equipment. Looking at the analysis principle of the XRF analysis equipment, the content of the target element is calculated by regression calculation of the calibration curve method, and in order to calculate the content of the target element, a calibration curve of the target substance and the target element should be prepared.

As described above, the condition of the standard sample used for preparing the calibration curve should be a sample having a wide range of concentrations, and the standard sample used for preparing the calibration curve does not exist in various concentrations according to the concentrations of the world-standard Primary-STD. In the steel industry, only a small portion of the working-STD & House Samples are manufactured and used to prepare calibration curves.

In the prior art, when a home standard sample (hereinafter referred to as a standard sample) is produced, the slag made of lump is crushed into 200 mesh by a crushing facility, and the concentration of the target element is obtained by wet analysis.

In this way, crushed slag of various concentrations can be secured.

Specific slag mixing is necessary to prepare a standard sample with the desired concentration of element based on the concentration of the slag secured. In order to prepare a standard sample as described above, after setting the expected concentration value of the target element, the already crushed slag is mixed at a concentration ratio in a wide bowl.

In the mixing method, the mixed slag is stirred while stirring with a spoon, and in particular, it is stirred by a quarter method. In this way, when the agitation of the slag is completed by manual work, the stirred sample is taken by the four-part method, and the target concentration of the target element is obtained by wet analysis.

However, the conventional method as described above was not suitable for use as a standard sample because a standard sample of a desired concentration was not accurately produced and a wide range of data deviation of the manufactured standard sample was obtained by manual slag stirring. The data calculated by the calibration curve made of the sample has caused a lot of problems in reliability.

In addition, in the process of manually stirring the slag and manufacturing a standard sample, there was a big disadvantage of reducing the efficiency of the operator.

The present invention is to solve the conventional problems as described above, the purpose is to produce a working standard sample (Working-STD & House Sample), it is possible to easily mix the slag of a certain concentration to the target standard sample It can be easily secured, thereby securing the manufacturing capacity of the standard sample and eliminating the need to purchase the standard sample (P-STD) to achieve cost reduction and improve the accuracy of analysis by calculating the data of various target components. The aim is to provide an automatic slag stirrer to achieve this.
