In this embodiment, a steel material product is manufactured in the electric furnace EF of FIG. The electric furnace EF applies a high voltage to the electrode EL to generate an electric arc EA. The electric furnace EF melts, for example, iron scrap with arc heat. Molten steel ML produced by melting is processed into steel products after going through processes such as composition adjustment, casting and rolling.

The electric power used in the electric furnace EF of the present embodiment is electric power that does not emit carbon dioxide and is generated from a non-fossil power source such as renewable energy. Renewable energy here refers to the following energy sources.
(1) Solar power (2) Wind power (3) Hydro power (4) Geothermal power (5) Biomass (organic matter derived from animals and plants that can be used as an energy source (excluding crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these. ).)
(6) In addition to the energy sources listed in 1 to 5 above, among energy sources other than crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these, those that can be used permanently as an energy source for electricity. Those specified by Cabinet Order as permitted

Non-fossil power sources include, for example, nuclear power as well as renewable energy. Electricity generated from non-fossil power sources includes the following two.
1. Value of electricity itself (kWh value, etc.)
2. Value as non-fossil value In this embodiment, "2. Value as non-fossil value" of the above two values is referred to as non-fossil value. The electric furnace EF uses electric power defined as a non-fossil value. The non-fossil value here is the value recorded as a non-fossil power source when calculating the non-fossil power source ratio in Japan's "Energy Supply Structure Advancement Act". Non-fossil value is the value purchased by new electricity retailers to meet the stated target value.

Power, defined by non-fossil values, is obtainable and verifiable, for example, using at least one of the following three means.
(1) Non-fossil certificate (2) Green power certificate (3) J credit

A non-fossil certificate is a certificate that expresses the environmental value of electricity generated by renewable energy.

A green power certificate is a certificate of the environmental value of power generated by renewable energy. A serial number is attached to the Green Power Certificate, making it unique. The green power certificate includes information on the amount of power generated, the period of power generation, the method of power generation, and the date of issuance of the certificate. The green power certificate further includes information on the name of the certification body and the name of the certificate issuer.

J-credit is a system in which the government certifies the emission reduction amount and absorption amount of greenhouse gases such as carbon dioxide as "credits".

Additionally or alternatively, power defined in non-fossil value may also be obtained and verifiable by the following means.
(4) Power generation using solar power generation equipment owned by the company

As an alternative, the power used in the electric furnace EF may be power defined as a zero-emission value rather than power defined as a non-fossil value. The zero-emission value here is the value for which the carbon dioxide emission coefficient in Japan's "Law Concerning Promotion of Global Warming Countermeasures" (hereinafter referred to as the Global Warming Law) is zero. Specifically, the zero-emission value is calculated by multiplying the amount of electricity from the non-fossil fuel certificates procured by the electricity retailer when calculating the post-adjustment emission factor by the "national average factor". A value that can be subtracted from emissions. When power purchasers such as manufacturers report their carbon dioxide emissions to the government based on the Global Warming Law, the carbon dioxide emission factor for power with zero emission value is zero. For example, electricity defined as zero-emission value may be electricity generated by an existing electricity sales company using renewable energy, such as hydropower, or nuclear power. Power, defined as a zero-emission value, is obtainable and verifiable by the following means.
(5) Contracts with electricity retailers (e.g. “Aqua Premium” (registered trademark) and “Aqua Energy 100” provided by TEPCO Energy Partner (registered trademark))

For each of the means (1) to (5) exemplified above, information such as a certificate certifying that the electric power used in the electric furnace EF is defined as non-fossil value or zero emission value is unique It is obtained from a certificate issuing business or a certification authority as unique certification information. The above means (1) to (5) are examples, and can be replaced by any other means that proves that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value. be.

In this embodiment, the method for certifying that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value is to obtain the certification information by any of the above (1) to (5). There is a way to prove Certificates are purchased at auctions or from intermediaries. The certification information is stored in the storage unit 13 or the inventory management system.

As an additional example, certification information may include non-fossil residue information certified by any manufacturer.

The control unit 11 of the information processing device 1 acquires order information for ordering the production of steel products using electric power defined as non-fossil value or zero emission value. The order information may be acquired by being received from another information processing device via the network and the communication unit 12, or may be acquired by being manually input to the information processing device 1. FIG. Order information includes, for example, JIS standards, quantity, or delivery date information.

The control unit 11 determines manufacturing standards for steel products from the order information. Manufacturing specifications may include information such as product type, manufacturing route, product weight, steel grade, and the like. Here, for convenience of explanation, the value of the product weight is m [ton]. Breeds include, but are not limited to, any of the following:
・Deformed steel bar・Wire rod・Flat steel・Shaped steel・H-shaped steel・Square steel・Round steel・Thick plate・Hot rolled plate・Thin plate

The control unit 11 refers to the product-specific yield table shown in FIG. A product-specific yield table is included in the storage unit 13 . The yield here is, for example, the tapping yield, the slab yield, and the rolling yield, but is not limited thereto. Each yield value is calculated by the following formula.
Rolling yield = product weight/rolling weight (good slab weight)
Slab yield = Weight of good slab / Weight of tapped steel
Extracted steel yield = Extracted steel weight / Total charged iron weight

Each yield value is an actual value between 0 and 1. Each yield value may be updated periodically (eg, monthly).

The control unit 11 determines the output yield value (any of a1 to a10), the slab yield value (any of b1 to b10), and the rolling yield value (c1 to c10) and read. Hereinafter, for convenience of explanation, the value of the tapping yield is set to a, the value of the slab yield is set to b, and the value of the rolling yield is set to c. Therefore, the following relational expression holds.
Rolling weight (good slab weight) = m/c
Output weight = (m/c)/b
Total charged iron weight = ((m/c)/b)/a

The control unit 11 determines the amount of electric power necessary for manufacturing the steel product from the product weight and the yield of the steel product included in the order information, as follows.

The control unit 11 calculates the rolling power consumption unit Er [kWh/t] using the following formula. "t" indicates "ton".
Basic unit of electric power for rolling Er = Rolling electric power/rolling weight (good slab weight)
Furthermore, the control unit 11 calculates the rolling power consumption Wr [kWh] using the following formula.
Wr=Er*rolling weight=Er*(m/c)

The control unit 11 calculates the casting power consumption rate Ec [kWh/t] using the following formula.
Basic unit of electric power for casting Ec=Amount of electric power for casting/Weight of output steel Furthermore, the control unit 11 calculates the amount of electric power for casting Wc [kWh] using the following formula.
Wc=Ec*output weight=Ec*(m/c)/b

The control unit 11 calculates the electric furnace power consumption rate Ea [kWh/t] using the following formula.
Electric furnace power consumption unit Ea [kWh/t]=Electric furnace power consumption/Steel output weight Furthermore, the control unit 11 calculates the electric furnace power consumption Wa [kWh] using the following formula.
Wa = Ea * Output weight = Ea * (m/c)/b

After calculating the rolling power amount Wr, the casting power amount Wc, and the electric furnace power amount Wa, the control unit 11 uses the following formula to calculate the necessary power amount Wrn [kWh] required to manufacture the steel product. calculate.
Wrn=Wr+Wc+Wa

The required electric energy is calculated as described above. Alternatively, in addition to the rolling power amount Wr, the casting power amount Wc, and the electric furnace power amount Wa, another power amount (for example, the power amount used in the office) may be added.

As shown in FIG. 4, the control unit 11 calculates the required amount of power as proof information proving that the power used in the electric furnace EF during the manufacture of steel products is defined as non-fossil value or zero emission value. , and stored in the order information DB of the storage unit 13 . Although the required power amount in this embodiment is stored as mill sheet information, it may be stored as another item as an alternative example. For example, when the required power amount is 5,213 kWh, the control unit 11 reads 5,213 kWh of certification information from the storage unit 13 . With this configuration, the control unit 11 can realize and prove that the electric power used in the electric furnace EF is electric power defined as non-fossil value or zero emission value. As an alternative example, the control unit 11 may store part of the required power amount in association with the certification information.

As an additional example, when the control unit 11 determines that the required power amount is not within the range of the power amount certified by the certification information in the storage unit 13, additional certification information can be purchased from the external system.

As shown in FIG. 5, the control unit 11 electronically or physically issues the mill sheet MS based on the information in the order information DB. If the mill sheet MS is physical, the mill sheet MS is attached to the steel product.

A mill sheet MS is an inspection certificate that proves whether a steel product satisfies requirements such as specified standards. The mill sheet MS includes, for example, the following mill sheet information 51 to 58, certification information 59, and code information 60.
is included.
・Certificate number 51 (unique serial number)
・Inspection number 52
・Product size 53
・54 pieces
・Mass 55
・ Tensile test result 56
・Bend test result 57
・Chemical composition 58

The certification information 59 here includes the serial number of the green power certificate and information on the amount of power certified by the green power certificate (here, 5,213 kWh).

As an additional example, the mill sheet MS may include, as mill sheet information, information on the amount of power required to manufacture the steel material product or a yield value.

Mill sheet MS includes code information 60 for accessing mill sheet information and certification information. As shown in FIG. 5, the code information 60 is a QR code (registered trademark). Alternatively, code information 60 may be any code, such as a bar code. The code information 60 can be read by any user terminal (eg smart phone). Upon detecting that the code information 60 has been read, the control section 11 may transmit the mill sheet information and the certification information to the user terminal. That is, the mill sheet information and certification information are clouded and can be read by the user terminal.

As an additional example, the information processing device 1 may participate in a distributed ledger (Hyperledger) type blockchain network as a node. A blockchain network may be a public network connected to the Internet or a private network. The control unit 11 registers information (for example, mill sheet information and certification information) stored in the order information DB in the blockchain. Information stored in the order information DB may be stored in one block of the blockchain for each record.

An information processing method by the control unit 11 of the information processing device 1 will be described with reference to FIG.

In step S1, the control section 11 acquires order information. In step S2, the control unit 11 determines manufacturing standards and the like from the order information. In step S3, the control unit 11 determines the amount of electric power necessary for manufacturing the steel product from the product weight and the yield of the steel product included in the order information. In step S<b>4 , the control unit 11 stores at least part of the required power amount in the storage unit 13 in association with proof information proving that the power is defined as a non-fossil value or a zero emission value. At step S5, the control unit 11 issues a mill sheet for the steel product.
