Embodiment Construction

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0030] like figure 1 and figure 2 Shown, the present invention proposes a kind of hot rolling strip sampling method of the present invention, comprises:

[0031] Step A: Generation of steel coil identity information:

[0032] The computer of the production control system makes a rolling plan before rolling, and codes each steel coil to be rolled in advance to form the identity information of the steel coil (that is, the coil number), the code on each steel coil and the rolling code. Manufacturing plan information includes at least: contract number information, applicable metallurgical specification information, furnace number information, and finished product thickness and width specification information; codes are, for example, numbers, letters, or combinations of...

Abstract

The invention provides a hot continuous rolled strip steel sampling method. The method comprises the steps of A, generating steel reel identity information: making a rolling plan before rolling by a computer, and pre-coding to-be-rolled steel reels; B, screening steel reel identity information: during rolling, according to codes, enabling the steel reels with the same metallurgic standard information, the same furnace number information and the same thickness information to generate a same trial batch number by the computer; C, determining sampled steel reel identity information: generating asampling mark for a steel reel in the same trial batch number and notifying the code of the steel reel with the sampling mark to a sampling process by the computer; and D, performing sampling according to the steel reel with the sampling mark. According to the method, the working intensity of samplers is reduced; the product yield is increased; and the production rhythm is accelerated.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to the detection of the mechanical properties of hot-rolled strip steel, in particular to a sampling method for hot-rolled strip steel. Background technique [0002] When the hot strip is delivered, a batch of products is accepted or rejected at a time based on the tests conducted on the sampled products, and this batch of products is called the test unit. According to 8.3.2 of "GB / T 17505-1998G General Technical Requirements for Delivery of Steel and Steel Products", the test unit usually consists of the following: a) the same smelting furnace number; b) the same furnace tank number; c) the same heat treatment state Or heat treatment batch; d) the same shape; e) the same thickness. The size of the test unit determines the sampling frequency. [0003] Original sampling frequency design for hot-rolled products: same contract number, same furnace number, continuous within the plan, samplin...
