Problems solved by technology

Using the traditional method has the following disadvantages. First, the sample delivery personnel (the operator who loads the sample into the shell and puts it into the pneumatic sample delivery device for sample delivery) manually fills in the sample ticket, which takes auxiliary time and easily leads to clerical errors. And paper sample tickets are easy to burn out at high temperature; second, analysts manually input the furnace number and sample code into the analysis computer, which takes a certain amount of auxiliary time and is easy to enter incorrectly
Because the traditional method needs to spend a certain amount of auxiliary time, it affects the smelting cycle of steelmaking

Embodiment 1

[0051] Taking the analysis of steelmaking converter samples as an example, it is assumed that a steelmaking plant has 3 converters, corresponding to 3 sample delivery pipelines, and a converter L2 process control system.

[0052] The automatic analysis and control system codes the 3 pipelines and 3 converters and corresponds them one by one. The number of the No. 1 converter is Z01, and the corresponding pipeline is GZ01; the number of the No. 1 converter is Z02, and the corresponding pipeline is GZ02; The serial number is Z03, and the corresponding pipeline is GZ03; the three converters share one L2 system, which is called converter L2. The automatic analysis control system defines the sample code of the converter, the code of the first sample of the No. 1 converter is 1101, the code of the second sample is 1111; the code of the first sample of the No. The code of the sample is 1211; the code of the first sample of converter No. 3 is 1301, and the code of the second sample is...

Embodiment 2

[0060] Taking the sample analysis of vacuum refining furnaces in steelmaking as an example, it is assumed that there are 2 vacuum refining furnaces in a steelmaking plant, corresponding to 2 sample delivery pipelines, and 2 vacuum refining furnace L2 process control systems.

[0061] (1) The automatic analysis and control system coded the 2 pipelines and 2 vacuum refining furnaces and made a one-to-one correspondence. The number of the No. 1 vacuum refining furnace is ZK01, and the corresponding pipeline is GZK01; the number of the No. 2 vacuum refining furnace is ZK02. The corresponding pipeline is GZK02; the 2 L2 systems of the 2 vacuum refining furnaces are respectively ZK1L2 and ZK2L2. The automatic analysis control system defines the sample code of the vacuum refining furnace. The code of the first sample of the No. 1 vacuum refining furnace is 1401, and the code of the second sample is 1411; the code of the first sample of the No. 2 vacuum refining furnace is 1501, the c...

Abstract

The invention discloses an automatic control system for steelmaking inspection and testing production. The automatic control system comprises an L2 control system, an automatic analysis control system, a pneumatic sample transporting control system, an analyzer computer and an analyzed data storage system, wherein the L2 control system is used for process control of each steelmaking production unit, the automatic analysis control system is used for automatic control of an analysis system, the pneumatic sample transporting control system is used for pneumatic sample transporting control of each steelmaking production unit, and the analyzer computer receives sample information transmitted down from the automatic analysis control system and uploads the sample information to the analyzed data storage system automatically via a network. By the automatic control system, a great amount of auxiliary time can be saved, molten steel smelting period can be shortened and considerable economic benefit can be created.

Description

technical field [0001] The invention relates to a steelmaking control system, in particular to an automatic control system for steelmaking inspection, testing and production and a control method thereof. Background technique [0002] With the large-scale development of the steel industry and the fierce competition among enterprises, in order to maximize the benefits and production capacity, steel mills do everything possible to reduce the auxiliary time of steelmaking, and shortening the sample analysis time is one of the important means. [0003] The sample code is the unique identification code of the sample, which consists of two parts. The first part is the heat number, which is the unique identification code of a furnace of molten steel, and the second part is the sample code, which is the unique identification of the sample of molten steel in different smelting stages. code. [0004] The traditional method is to manually fill in the heat number and sample code rep...
