[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an order information processing apparatus for, for example, an iron and steel maker to select a manufacturing process and manufacturing conditions in accordance with a performance request at the time of receiving an order for steel materials and the like and to design the performance and quality of the product. About.

[0002]

2. Description of the Related Art In a steel maker, when a customer requests the performance and quality of a steel material at an inquiry stage, such a request is made based on the performance items and performance value ranges (or JIS, ASME, etc.) that are publicly standardized. Manufacture if the content satisfies the performance items and performance value ranges that are standardized between the customer and the manufacturer, or the performance items and performance value ranges that the manufacturer has independently standardized (so-called in-house standards). It is possible to receive an order from a customer as there is no problem, but if the request is out of the standardized performance item or partially or completely out of the performance value range, satisfy the request before receiving the order It is necessary to consider whether steel can be manufactured.

[0003] In such a study, a steel material satisfying the required performance can be manufactured, for example, by using an information processing device that stores a predetermined database, and based on, for example, data that is converted into a mathematical expression or a numerical table with a focus on the mechanical characteristics of the steel material. In addition to determining whether or not manufacturing is possible, if manufacturing is determined to be impossible, various manufacturing condition values of data are changed to satisfy performance requirements, and conditions for enabling manufacturing are determined.

[0004]

However, in the above-mentioned conventional order information processing apparatus, the amount of data of a mathematical expression or a numerical value table used for judging the availability of production is large, and if it is judged that production is impossible, the data of the data cannot be obtained. In changing the various manufacturing condition values to determine the manufacturable conditions, there are many manufacturing conditions that are variables, many restrictions, and it is necessary to evaluate the correlation with the performance requirements of other orders,
Logic becomes huge.

[0005] For this reason, it is inevitable to rely on processing on a large computer, and the maintenance load on the database accompanying the development of new products or changes in manufacturing conditions is large, and stable processing cannot always be performed. However, there is an inconvenience that a long processing time is required until the actual product production starts. The present invention has been made in order to solve such inconveniences, and it is possible to downsize a computer, to shorten the processing time from inquiries to the actual start of product production, and to create a database. An object of the present invention is to provide an order receiving information processing apparatus capable of reducing a maintenance load.

[0006]

In order to achieve the above object, an order information processing apparatus according to the present invention selects a manufacturing process and manufacturing conditions in accordance with a performance request at the time of receiving an order for a product, and selects a manufacturing process. In an order processing device that performs performance and quality design, a table group in which a plurality of known manufacturing processes and manufacturing conditions and performance and quality ranges guaranteed by each of them are registered is grouped for each product standard. A storage means for storing, a table of a group of the same standard as the standard of the ordered product, and a table of the performance, quality and the performance registered in the storage means and the quality range required at the time of the order, and then a group of another standard. Compare in the order of the table, required performance,
Comparing and judging means for judging whether or not a manufacturing process and a manufacturing condition satisfying the quality are present in the table group of the storage means; and a performance and a manufacturing process satisfying the quality required at the time of receiving the order by the comparing and judging means. If it is determined that the manufacturing conditions do not exist in the table group of the storage means, a registration is made to create a table of manufacturing processes and manufacturing conditions satisfying the requirements and a range of performance and quality guaranteed by each of them, and to register the table. Means.

Here, the performance requirements include the chemical composition, mechanical composition (yield point, tensile strength, elongation, impact absorption energy, etc.) of the steel material, and the internal quality of the steel material (crystal grain size, inclusions, internal defects, etc.). ), Special properties (high-temperature strength, crack susceptibility, etc.), and product quality (surface properties, flatness, dimensional tolerances, etc.) in a broader sense of performance. Refining, secondary refining, ingot casting, heating, rolling, controlled cooling, cutting / shearing, heat treatment, etc., which are processes, and the manufacturing conditions are the operating conditions of each manufacturing process to achieve performance, Composition, refining conditions, heating temperature / time, rolling temperature, controlled cooling conditions (start temperature, end temperature, time), cutting / shear scoring dimensions, heat treatment form / temperature / time, etc. Chemical composition and equipment meeting the performance requirements The quality of the product refers to the degree of the appearance / shape of the steel material, such as surface properties (scratch, roughness), flatness, dimensional tolerance, etc., and product specifications. Is a standardization of performance items and performance value ranges, and is a public / national standard JIS, AS
In addition to ME, ASTM, BS, DIN, ISO, etc., it includes agreement standards with specific customers and standards specified by the manufacturer.

Storage unit (registering means) 2 for storing specific manufacturing condition values at the time of actual manufacturing corresponding to the above, and steel materials for which performance and quality required at the time of receiving an order and performance and quality registered in storage unit 2 have been ordered. Table of the same standard as that of the standard, and then a table of the group of another standard, in order of whether the manufacturing process and the manufacturing conditions satisfying the required performance and quality exist in the table group of the storage unit 2. Based on a data input value from the input unit 1, a table of the manufacturing process and manufacturing conditions and a range of performance and quality guaranteed by each of them is newly created based on the data input value from the input unit 1. It comprises a design means 4 for registering and outputting a record in the storage unit 2, and an output section 5 for outputting a determination result of the comparative determination unit 3 printer, the terminal computer monitor or the manufacturing process.

The manufacturing condition values at the time of actual manufacturing include material composition constraints, manufacturing device control condition values, product inspection reference values, and the like. The manufacturing condition values are assigned to each standard group table.

Next, referring to FIG. 2, the operation of the order information manufacturing apparatus having such a configuration will be described. Here, in FIG. 2, step S1 corresponds to the input unit 1, and step S2,
Steps S3, S5 and S6 correspond to the comparing and judging means 3, steps S4 and S7 correspond to the output section 5, and steps S8 and S9 correspond to the designing means 4.

The process moves to step S9, where the creation table is registered in the A standard group of the storage unit 2, and used for the subsequent processing.

As described above, in this embodiment, a complicated information processing logic can be implemented only by constructing and maintaining a database that defines the limits of the manufacturable performance and quality level under the manufacturing process and manufacturing conditions for each standard name. Because it is possible to judge the availability of manufacturing and select the conditions that can be manufactured without using it, it is possible to downsize the processing computer, and of course, from the inquiry to the actual start of product manufacturing. The time can be greatly reduced, and the maintenance load on the database can be reduced.

The program for executing the above processing is R
The program is electronically stored in a storage medium such as an OM, a flexible disk, a compact disk, or a hard disk, and a controller reads the program from the storage medium and executes the program.
