- C is an element for controlling the strength of steel.
- the upper limit of the C content is set to 1% or less.
- Si 3% or less Si is added to suppress the precipitation of cementite or to refine the cementite. If the Si content exceeds 3%, it becomes brittle and the moldability deteriorates. Therefore, the upper limit of the Si content is set to 3% or less.
- Mn acts as a hardenable element and suppresses the precipitation of coarse cementite. When 5% or more is added, a large amount of ⁇ can be retained, so that ductility is also improved. However, if the Mn content exceeds 30%, the moldability will decrease, so the upper limit of the Mn content should be 30% or less.
- ⁇ P 0.07% or less P embrittles steel. Therefore, the upper limit of the P content is 0.07% or less.
- ⁇ S 0.01% or less S forms MnS and deteriorates moldability. Therefore, the upper limit of the S content is 0.01%.
- ⁇ Al 3% or less Al fixes N as AlN to improve moldability. By adding a large amount of Al, residual ⁇ can be formed and the moldability is improved. On the other hand, if the Al content exceeds 3%, it becomes embrittled due to the formation of an intermetallic compound, so the upper limit of the Al content is set to 3% or less.
- ⁇ N 0.01% or less
- N When N is solid-solved in steel, formability deteriorates. Further, if a large amount is contained, a large amount of nitride such as AlN is formed and the moldability is lowered. Therefore, the upper limit of the N content is 0.01% or less.
- Ti forms carbides and nitrides to increase the strength of steel. However, if it is contained in excess of 0.5%, coarse precipitates are formed and the moldability is deteriorated. Therefore, the upper limit of the Ti content is 0.5% or less.
- Nb forms carbides and nitrides to increase the strength of steel. However, if it is contained in excess of 0.5%, coarse precipitates are formed and the moldability is deteriorated. Therefore, the upper limit of the Nb content is 0.5% or less.
- Mo 1% or less Mo can be added to increase the strength and suppress the precipitation of cementite. If 1% or more is added, the moldability is lowered due to coarse Mo carbide, so the upper limit of Mo content should be 1% or less.
- the system performs a characteristic simulation based on the component information (step S611) and determines the component strength (step S612).
- the characteristic simulation includes a collision deformation simulation, and the component strength can be determined by the simulation.
- This system acquires plate thickness, component strength, and shape data as input information (step S613), and determines the material properties of the steel sheet based on the input information (step S614).
- the system determines product information including components and production conditions for producing a material satisfying the material properties acquired in step S614 based on the performance database 121.
- the system 100 ejects and melts the molten steel whose composition is adjusted based on the determined product information (step S631). Subsequently, the system 100 performs rolling and heat treatment based on the determined product information to manufacture a steel sheet (step S632).
- step S632 when the actual component after component adjustment fluctuates by 1% or more with respect to the component determined in step S620, the system rolls and / or rolls based on the actual database 121 using the actual component after component adjustment.
- the heat treatment conditions are updated to produce a steel sheet (step S632).
- the following is a process performed by a product maker that uses parts, and the manufactured steel sheet is subjected to processing such as pressing and welding (step S640) to complete the parts (step S650).
- the component is determined in consideration of the mechanical properties in press molding, but data on corrosion resistance and chemical conversion treatment property may be combined with this component.
- the product information satisfying the additional performance required for the component may be determined.

Abstract
Description
部品の形状データを含む入力情報に基づき、前記部品の素材を前記部品に加工するのに必要な材料特性を取得する特性取得ステップと、
前記特性取得ステップで取得された材料特性を満たす素材を製造するための成分及び製造条件を含む製品情報を決定する製品情報決定ステップと、
を含む。

上記の製造方法により板を製造する。
制御部を備える製品情報決定装置であって、前記制御部は、
部品の形状データを含む入力情報に基づき、前記部品の素材を前記部品に加工するのに必要な材料特性を取得し、前記材料特性を満たす素材を製造するための成分及び製造条件を含む製品情報を決定する。
Cは鋼の強度を制御するための元素である。Cの含有量が1%を超えるとセメンタイトが粒界に粗大に析出して成形性が低下する。このためCの含有量の上限は1%以下とする。
Siは、セメンタイトの析出を抑止またはセメンタイトを微細化するため、添加する。Siの含有量が3%を超えると脆化して成形性が低下するため、Siの含有量の上限は3%以下とする。
Mnは焼入れ性元素として働き、粗大なセメンタイトの析出を抑制する。5%以上添加するとγを多く残留させることができるようになるため、延性も向上する。ただし、Mnの含有量が30%を超えると成形性が逆に低下するため、Mnの含有量の上限は30%以下とする。
Pは鋼を脆化する。このためPの含有量の上限は0.07%以下とする。
SはMnSを形成して成形性を劣化させる。このため、Sの含有量の上限は0.01%とする。
AlはNをAlNとして固定して成形性を向上させる。Alは、多量に添加することで残留γの形成も可能であり、成形性も向上させる。一方、Alの含有量が3%を超えると金属間化合物の形成で脆化することから、Alの含有量の上限は3%以下とする。
Nは鋼中に固溶すると成形性が低下する。また、多量の含有はAlNなどの窒化物を多量に形成させ成形性を低下させる。このため、Nの含有量の上限は0.01%以下とする。
Tiは炭化物及び窒化物を形成して鋼の強度を上げる。ただし、0.5%を超えて含有すると粗大な析出物を形成して成形性が低下する。このためTiの含有量の上限は0.5%以下とする。
Nbは炭化物及び窒化物を形成して鋼の強度を上げる。ただし、0.5%を超えて含有すると粗大な析出物を形成して成形性が低下する。このためNbの含有量の上限は0.5%以下とする。
Vは、炭化物及び窒化物を形成して鋼の強度を上げる。ただし、3%を超えて含有すると粗大な析出物を形成して成形性が低下する。このためVの含有量の上限は3%以下とする。
Moは強度増加及びセメンタイトの析出抑制のために添加することができる。1%以上添加すると粗大なMo炭化物で成形性が低下することからMoの含有量の上限は1%以下とする。
Crは、耐食性を上げるために添加することができる。ただし40%を超えるとσ相などの脆化層が析出して成形性が低下する。このためCrの含有量の上限は40%以下とする。
Niも耐食性向上目的で添加することができる。Niが20%を超えると金属間化合物の形成などで成形性が低下するため、Niの含有量の上限は20%以下とする。
以下、本開示の一実施例に係る処理について説明するが、本開示は本実施例に限定されるものではない。図6は、本開示の一実施例に係るシステムの処理の概要を示す。ここではシステムが、鋼板を素材とする部品を製造する場合を示す。図6のシステムは、上述のシステム100の構成に加えて、鋼板をプレス加工等する装置を含む。
