Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings of the embodiments, and it is obvious that the described embodiments are a small part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work based on the embodiments of the present invention belong to the protection scope of the present invention.
An automatic setting method for the width of an acid rolling cutting edge and a shearing edge comprises the following steps: establishing a corresponding sour rolling necking amount database in a secondary system, and simultaneously establishing a trigger in the secondary system; after the trigger is activated, the system automatically reads corresponding acid rolling necking quantity from an acid rolling necking quantity database according to the steel type, thickness and width; and the third-stage system downloads the target width of the acid-rolled finished product to the second-stage system, and the second-stage system sums the read acid-rolled necking quantity and the target width of the acid-rolled finished product, and automatically sends the sum as the acid-rolled cutting edge shearing edge width to the trimming shears to control the trimming width on site.
And the sour rolling necking amount database is established according to the data base of the sour rolling necking amounts of different steel types, different thicknesses and different widths.
Example 1: taking the hot rolled steel type 22MnB5S, the nominal thickness of the acid rolled product is 1.0mm, and the nominal width of the acid rolled product is 1250mm as an example, the target width of the acid rolled product issued to the secondary system by the tertiary system is 1254.5mm, when the secondary system receives the steel coil production information, the trigger is automatically activated, the trigger is automatically sent to the acid rolled necking quantity database of the secondary system after being activated, and the corresponding acid rolled necking quantity is read to be 1.5mm according to the steel type, the nominal thickness and the nominal width. The secondary system adds the target width 1254.5mm of the acid-rolled product and the acid-rolled necking quantity 1.5mm to obtain the width 1256mm of the cutting edge of the acid-rolled cutting edge, and then automatically sends the width 1256mm to the cutting edge shear on site to control the cutting edge width.
Example 2: taking the hot rolled steel DD11, the nominal thickness of the acid rolled product is 1.0mm, and the nominal width of the acid rolled product is 1250mm as an example, the target width of the acid rolled product issued to the secondary system by the tertiary system is 1255mm, when the secondary system receives the steel coil production information, the trigger is automatically activated, the trigger is automatically sent to the acid rolled necking quantity database of the secondary system after being activated, and the corresponding acid rolled necking quantity is read to be 2mm according to the steel type, the nominal thickness and the nominal width. The secondary system adds the target width 1255mm of the acid-rolled product and the neck reduction 2mm of the acid-rolled product to obtain the width 1257mm of the cutting edge of the acid-rolled cutting edge, and then automatically sends the width 1257mm of the cutting edge to the cutting edge shear on-site to control the width of the cutting edge.
Example 3: taking the hot rolled steel grade DD11, the nominal thickness of the acid rolled product is 2.0mm, and the nominal width of the acid rolled product is 1200mm as an example, the target width of the acid rolled product issued by the third-level system to the second-level system is 1256mm, when the second-level system receives the steel coil production information, the trigger is automatically activated, the trigger is automatically sent to the acid rolled necking quantity database of the second-level system after being activated, and the corresponding acid rolled necking quantity is read to be 1mm according to the steel grade, the nominal thickness and the nominal width. The second-level system adds the target width 1256mm of the acid-rolled product and the acid-rolled necking amount 1mm to obtain the width 1257mm of the acid-rolled trimming shearing edge, and then automatically sends the width 1257mm of the acid-rolled trimming shearing edge to the trimming shears to control the trimming width on site.
