Embodiment 1

[0037] The present invention is a full-process temperature field calculation system for hot-rolled bars and wires based on a rolling program table, and the specific implementation steps are as follows:

[0038] Step 1. In the rolling program table module, input the rolling program data of different specifications under each production line as the basic data of the subsequent modules.

[0039] Step 2: The production line layout module splits the production line into multiple process units (roughing mill unit, intermediate rolling mill unit, pre-finishing mill unit, finishing mill unit and reducing mill unit, water cooling unit and cooling unit. bed unit), and provide input parameter configuration for each process unit, the user can select the corresponding process unit to combine according to different production lines.

[0040] Step 3: In the temperature evolution module of the whole process, the data of the rolling program table is directly used for calculation in offline cal...

Embodiment 2

[0042] Take a bar factory The rolling program table (single-line rolling) of threaded steel bars is used as an example to calculate. The plant has a total of 18 rolling mills. There is one set of controlled chilled water tanks behind the intermediate rolling mill and two controlled chilled tanks behind the finishing mill. The cooling bed is 12m wide and 110m long. Users first directly import in the form of an Excel table See Table 1 for the rolling program table of threaded bars (you can also enter data manually in the parameter input window).

[0043] The rolling program table analysis subsystem reads the imported rolling program table data (Table 1), and recognizes that the front 6 stands of the production line are rough rolling mills (RS), the middle 6 stands are medium rolling mills (MS), The rear 6 stands are the finishing mill unit (FS), and at the same time identify the spacing value of each stand, the type of pass, the flat state of the rolling mill, the reduction ...

Abstract

The invention discloses a whole-process temperature field calculation system for hot-rolled bars and wires based on a rolling program table. The system includes: a rolling program table analysis subsystem, a production line layout subsystem, a temperature field calculation subsystem, and a graph processing system Subsystem and database; the invention fully combines the calculation characteristics of the rolling program table, and proposes a full-process temperature field calculation system for hot-rolled bars and wires based on the rolling program table, which satisfies the designers and field technicians quickly, easily and intuitively. Calculate and analyze the actual needs of the temperature evolution of the entire production process of each product specification, and provide a more accurate and comprehensive calculation basis for the layout and design of the production line controlled cooling process and the adjustment of the on-site controlled cooling process.

Description

technical field [0001] The invention relates to the field of production of hot-rolled bars and wires, in particular to a temperature field calculation system for the whole process of hot-rolled bars and wires based on a rolling program table. Background technique [0002] At present, there are hundreds of ordinary hot-rolled bar, high-speed wire and high-speed bar manufacturers in China. With the implementation of the new national standard for threaded steel bars (GB / T 1499.2-2018), on the basis of meeting the requirements of the national standard, ordinary hot-rolled bars will continue to develop in the direction of reducing alloy content, negative tolerance control and increasing output. The rolling speed of high-speed wire rod is high, and the final rolling speed can reach more than 100m / s, which is suitable for the production of small-sized hot-rolled wire rod. Quality and organizational performance are breakthrough directions. High-speed bar is to use the high rolling...
