Embodiment 1

[0028] figure 1 It is a schematic flowchart of a hot rolling automatic steel request control method in an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0029] Step 10: Obtain the first relationship between the previous batch and the next batch;

[0030] Specifically, the undertaking relationship of obtaining the previous batch to transfer to the next batch is the first relationship.

[0031] Step 20: Obtain the furnace number information of the next furnace;

[0032] Specifically, the information on which furnace is the next furnace to be converted is obtained.

[0033] Step 30: Obtain the benchmark information according to the furnace number information;

[0034] Specifically, determine which standard is used as the benchmark information according to the next furnace number to be transferred.

[0035] Step 40: Obtain the first time according to the reference information;

[0036] Specifically, according to the obtained reference...

Embodiment 2

[0063] A kind of hot-rolling of the present invention will be described in detail below automatically to steel control method, specifically as follows:

[0064] In an embodiment of the present invention, a method for controlling automatic steel extraction in hot rolling is provided. Firstly, on the first-level program page, a switching button for automatic steel demand and manual steel demand is added. After the automatic steel demand is switched in the program, then, the first relationship between the previous furnace and the next furnace is obtained, and the next furnace is obtained. The furnace number information of the furnace, the reference information is obtained according to the furnace number information, that is, if the next furnace is No. 1 and No. 2 furnaces, the reference information is based on the slab detected by the HMD at the entrance of the primary descaler, If the next heat is No. 3 and No. 4 furnaces, the reference information is based on the current heat t...

Abstract

The invention discloses a hot rolling automatic steel requiring control method. The method comprise the steps that the first relation between last heating and next heat is obtained; heat number information of next heat is obtained; according to the heat number information, reference information is obtained; according to the reference information, first time is obtained; according to the first relation, the first time reference is obtained, wherein the first time reference is the time interval from steel discharge signal completing to next steel requiring; and according to the first time and the first time reference, the first steel feeding time point is determined, and steel feeding operation is determined according to the first steel feeding time point. By means of the method, the technical problems that due to manual steel requiring, mental states of operators are different, steel discharge time intervals are different, and time control is inaccurate and uneven in the prior art are solved, and the technical effects that the steel requiring control rhythm precision is improved, standby time is shortened, the machine-hour volume number is improved, and therefore the steel rolling efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to an automatic steel-requiring control method for hot rolling. Background technique [0002] In steel rolling, since hot rolling was put into production, steel has been manually requested. Manual steel is used to adjust the rhythm of the next piece of steel according to the on-site rhythm. The precise control of the steel rhythm determines the efficiency of steel rolling. [0003] However, in the process of realizing the technical solution of the present invention, the inventor of the present application found that the above-mentioned prior art has at least the following technical problems: [0004] In the prior art, due to the need for steel manually, everyone’s concentration time is limited, and the reaction time of each person is also different. Sometimes the time to ask for the next piece of steel is too slow due to the placement of steel on the spot, or the rhythm is une...
