The controller 170 pre-stores information related to a predetermined heating rate, and the controller 170 controls the rate of increase in the temperature of the heating unit based on the information related to the heating rate. Here, the temperature increase rate of the heating part can be confirmed through Comparative Examples 1 and 2 and Example 1 as follows. In addition, the input amount of the object, the input type, the heating method of the object, the heating time, and the analysis method for measuring the optimum heating rate of the heating part are the same, and the degree of reduction of the object is compared by changing the heating rate.

Comparative Example 1

After inserting the object into the working part, the heating part is heated by setting the heating rate to 20K/min, and after 30 and 40 minutes from the start of heating the object, samples are collected from the object and analyzed by SEM-BSE. conducted. The analysis results of Comparative Example 1 as above are shown in FIGS. 9 and 10. Here, the operating temperature for recycling the object is set to 850 degrees Celsius, which is equally applied to both Comparative Example 2 and Example 1.

When 30 minutes have elapsed from the temperature rise of the heating unit, the crack information of the object is weak as shown in FIG. 9 in a temperature increase rate environment of 20K/min. Correspondingly, as shown in FIG. 10, it can be confirmed that the degree of reduction of the object is also weak after 40 minutes.

Comparative Example 2

After putting the object into the working part, the heating part is heated by setting the heating rate to 30K/min, and after 30 and 40 minutes from the start of heating the object, samples are collected from the object and analyzed by SEM-BSE. conducted.

In addition, referring to FIG. 14, more reduction is made to the object compared to Comparative Example 1, and it can be seen that the difference from Comparative Example 2 is insignificant.

Through this, it can be confirmed that the optimum heating rate for the object is configured to be 22K/min or more. In Comparative Example 1, the recovery rate of cobalt that can be recovered from the object is 70%, but in Example 1, it can be seen that the recovery rate of cobalt is 95%.

The working unit including the first working unit 121 to the third working unit 123 heat-treats the object under a pre-specified mixed reducing gas atmosphere, which is determined according to the partial pressure of carbon dioxide and carbon monoxide included in the pre-specified gas. Here, when carbon monoxide is generated during the heat treatment process for the object, the partial pressure in the work unit may be set by reflecting the generated carbon monoxide.

Here, the control unit 170 controls the gas preset through the gas supply unit 153 such that log(PCO ₂ /PCO), which is a logarithmic value obtained by dividing the partial pressure of carbon monoxide and the partial pressure of carbon dioxide, falls within the range of -2.15 to 2.5 or less. or may be exhausted through the first gas discharge unit 112c. Specifically, the logarithmic value (log(PCO ₂ /PCO)) based on the division of the partial pressure between carbon monoxide and carbon dioxide is in the range of -2.15 to 2.5, but the logarithmic value is adjusted to decrease as the internal temperature of the working unit increases. do.

The first internal temperature, the second internal temperature, or the third internal temperature corresponding to the first work unit 121, the second operation unit 122, and the third operation unit 123, respectively, is 500 to 600 degrees Celsius and 600 degrees Celsius. to 700 degrees Celsius, 700 to 800 degrees Celsius, 800 to 900 degrees Celsius, and 900 to 1000 degrees Celsius, the control unit 170 through the gas input unit 110 and the first gas discharge unit 112c Additional input of a predetermined gas such that the aforementioned logarithmic value falls within at least one of the ranges of 0.45 or more and 2.50 or less, -0.20 or more and 2.15 or less, -0.90 or more and 1.85 or less, -1.55 or more and 1.60 or less, and -2.15 or more and 1.40 or less, respectively. or control emissions.

For example, the control unit 170 suppresses the generation of carbon by adjusting the input amount of carbon dioxide included in the predetermined gas in the heat treatment process of the object so that it is not small, and adjusts the input amount so that the input amount is not excessive, thereby shortening the heat treatment process time. .

When the predetermined amount of the injected gas is excessive, the control unit 170 may open the first gas discharge unit 112c formed in the input unit 110 to exhaust it. Prior to that, in order to minimize the pressure gradient that may occur in the process of exhausting the predetermined gas targeting the internal space of the input unit 110, the exhausting process inside the input unit 110 by the pressure maintaining unit 112d is preceded or may be concurrent.
