[0002] In profile rolling, upper and lower adjacent hole types are usually designed alternately with openings and closings to form or control corresponding sizes, and the hole types are arranged in sequence on the rolls of the same stand. However, the problem is that the roll body occupies a long time, the number of hole types is small, the rolls are not fully utilized, the roll utilization rate is low, and even in the rolling of large profiles, it is possible that the holes cannot be arranged.

[0003] Therefore, it is necessary to provide a new method and system for improving the utilization rate of the rolling mill rolls to solve the above technical problems. Summary of the invention

[0009] The hole profiles are sequentially arranged on the rolls based on the hole profile opening positions of the hole profiles, and the thickness of the intermediate roll tables between adjacent hole profiles is reduced, so as to achieve the purpose of improving the utilization rate of the rolls of the blooming rolling mill.

[0010] As a further optimization scheme of the present invention, the specific process of type identification of all hole types on the roll is as follows:

[0011] The shapes of all hole types on the roll are identified, and hole types of different shapes are classified to realize type identification of multiple hole types.

[0015] Determine the direction of hole placement and the hole type that is placed first;

[0016] Randomly select one of the hole types from the determined hole types and place it in the first place;

[0017] Based on the hole opening position of the hole arranged in the first place, the hole patterns with similar hole opening positions are arranged in sequence.

[0018] As a further optimization scheme of the present invention, based on the hole type arranged in the first place, the specific process of sequentially configuring the hole types with similar hole opening positions is as follows:

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] like Figure 1 As shown, a method for improving the utilization rate of a flaking mill roll comprises the following steps:

[0040] S1: Identify the types of all the holes on the roll;

[0041] S2: Determine the hole opening positions of different types of hole types;

[0042] S3: sequentially arranging the hole profiles on the rolls based on the hole profile opening positions of the hole profiles, reducing the thickness of the intermediate roll tables between adjacent hole profiles, so as to achieve the purpose of improving the utilization rate of the rolls of the blooming mill.

[0043] The hole pattern has two openings, which are respectively arranged on two sides.

[0044] The hole opening positions of the hole profile include the upper part of the side, the middle part of the side and the lower part of the side.

[0045] The specific process of type identification for all hole types on the roll is as follows:

[0046] The shapes of all hole types on the roll are identified, and hole types of different shapes are classified to realize type identification of multiple hole types.

[0047] The specific process of identifying the shapes of multiple hole types on the roll and classifying the hole types of different shapes is as follows:

[0048] The number of hole types on the roll is counted as N, and the shapes of all hole types are identified to obtain M hole types with different shapes, that is, to obtain M hole types. The M hole types are defined separately to obtain hole type 1, hole type 2... hole type M, where the number of hole type 1 is X1, the number of hole type 2 is X2... the number of hole type M is X m , X1+X2+……X m =N.

[0049] Sequentially configuring the pass profile on the roll based on the pass profile opening position of the pass profile specifically includes:

[0050] Determine the direction of hole placement and the hole type that is placed first;

[0051] Randomly select one of the hole types from the determined hole types and place it in the first place;

[0052] Based on the hole opening position of the hole arranged in the first place, the hole patterns with similar hole opening positions are arranged in sequence.

[0053] Based on the hole type placed in the first place, the specific process of configuring the hole types with similar hole opening positions in sequence is as follows:

[0054] Based on the hole opening position of the hole type arranged in the first place, find out the hole type closest to the hole opening position of the first hole type from the remaining hole types, and randomly select one of the hole types from this hole type for discharge; based on the hole opening position of the last arranged hole type, find out the hole type closest to the hole opening position of the last arranged hole type from the remaining hole types, and randomly select one of the hole types from this hole type for discharge, until the rollers are full.

[0055] In this embodiment, the specific process is as follows:

[0056] like Figure 2As shown, one of the slab rolling mills for rolling a certain special steel needs to be equipped with 5 hole types, the shapes of all the hole types on the rolls are identified, and the hole types with different shapes are classified into 5 types of hole types, namely, hole type 1, hole type 2, hole type 3, hole type 4, and hole type 5, among which the number of hole type 1, hole type 2, hole type 3, hole type 4, and hole type 5 is one;

[0057] Determine the hole opening positions of different types of hole types, hole type one has its hole opening at the top and the middle, hole type two has its hole opening at the bottom, hole type three has its hole opening at the top, hole type four has its hole opening at the bottom, and hole type five has its hole opening at the top. Adjacent hole types with hole opening positions are arranged alternately to control the size of the steel section.

[0058] like Figure 3 As shown, the conventional hole design method is to arrange the hole patterns on the rolls in sequence according to the rolling order. The roll length required to arrange these five hole patterns is 2575 mm (while the roll length of the factory is only 2300 mm).

[0059] like Figure 4 As shown, the present invention provides a design method, which determines the order of hole type arrangement from right to left, determines the hole type placed in the first place as hole type one, arranges the hole types with the same hole type opening position together, and finds the hole type type closest to the hole type opening position of the last arranged hole type from the remaining hole types based on the hole type opening position of the last arranged hole type, and selects any one of the hole types from the hole type type for arrangement until the roll is full, or first combines two by two, such as hole type two and hole type four together, hole type three and hole type five together, and the roll length required to arrange these five hole types is 2300mm; such a configuration reduces the thickness of the intermediate roller table between adjacent hole types, and more hole types can be configured, which greatly improves the roll utilization rate. Under the same roll length, the conventional design method can only configure 4 hole types, and the present invention can configure 5 hole types.

[0060] like Figure 5 As shown, a system for improving the utilization rate of a rolling mill roll comprises:

[0061] A type identification module 11 is used to identify the types of multiple hole types on the roll;

[0062] An opening position determination module 12 is used to determine the hole opening positions of different types of hole types;

[0063] The sequential configuration module 13 is used to sequentially configure all hole patterns based on the hole pattern opening positions of the hole patterns.
