Abstract
A method and device capable of calculating required material properties from a part shape, and determining a set of manufacturing conditions for a material satisfying the material properties are provided. A product information determining method includes a property acquisition step (S300) for acquiring, based on input information including shape data on a part, material properties required to work a material of the part into the part; and a product information determination step (S400) for determining product information including chemical compositions and a set of manufacturing conditions to manufacture the material satisfying the material properties.
Claims11
A product information determining method executed by a controller, the method comprising:
- acquiring, based on input information including shape data on a part, a material property required to work a material of the part into the part;
- determining product information including a chemical composition and a set of manufacturing conditions to manufacture the material satisfying the material property;
- transmitting the product information, via a communication interface, to a converter, a continuous casting machine, a heating furnace, a rougher, a finisher, an accelerated cooling device, and a winder;
- and
- controlling the converter, the continuous casting machine, the heating furnace, the rougher, the finisher, the accelerated cooling device, and the winder to manufacture a steel sheet for the part,
- wherein the material property is acquired by back-calculating a deformation process from the material to a shape of the part and performing a material property acquisition calculation so as to reduce a ratio of change in working of the material, and
- wherein the ratio of change in working of the material is defined by an average ratio of change in the distance between mesh points when the shape of the part is divided into a mesh.
A product information determining device comprising a controller configured to:
- acquire, based on input information including shape data on a part, a material property required to work a material of the part into the part;
- determine product information including a chemical composition and a set of manufacturing conditions to manufacture the material satisfying the material property;
- transmit the product information, via a communication interface, to a converter, a continuous casting machine, a heating furnace, a rougher, a finisher, an accelerated cooling device, and a winder;
- and
- control the converter, the continuous casting machine, the heating furnace, the rougher, the finisher, the accelerated cooling device, and the winder to manufacture a steel sheet for the part,
- wherein the material property is acquired by back-calculating a deformation process from the material to a shape of the part and performing a material property acquisition calculation so as to reduce a ratio of change in working of the material, and
- wherein the ratio of change in working of the material is defined by an average ratio of change in the distance between mesh points when the shape of the part is divided into a mesh.
