What is level 2 automation in steel industry

The steel industry is highly complex and competitive, requiring continuous improvement in production efficiency, quality, and safety. To achieve these goals, iron and steel enterprises need to adopt advanced automation technology to monitor, control and optimize the production process. The automation of the steel industry is divided into four levels, namely, the first level of automation, the second level of automation, the third level of automation, and the fourth level of automation. This article will focus on what is secondary automation in the steel industry, what it does, and its advantages.


level 2 automation in steel industry


Level 2 automation in the steel industry refers to the use of computer technology based on first-level automation to collect, analyze and process the operating parameters of production equipment in real time, generate optimized control instructions, and send them to the first-level automation system, thereby realizing production control. Optimal control of the process. The secondary automation system usually includes the following parts


1. Data Acquisition System

Responsible for collecting production data, such as temperature, pressure, flow, composition, etc., from the first-level automation system, sensors, instruments, and other equipment, converting the data into a standard format, and sending it to the data processing system.


2. Data processing system

Responsible for storing, calculating, analyzing, and processing the collected data, using mathematical models, expert systems, artificial intelligence, and other technologies to generate optimized control instructions or suggestions, and feedback on the results to the data display system and the first-level automation system.


3. Data display system

Through visualization technology, information such as data collection and processing, process model and simulation, optimization control and management are displayed on terminal devices, such as display screens, tablet computers, etc., and various reports are generated as required, such as production reports, quality reports, Energy consumption reports, etc., provide information support for production management and decision-making.


4. Communication network

Responsible for connecting the data acquisition system, data processing system, and data display system to realize data transmission and exchange.


The role and advantages of secondary automation in the iron and steel industry mainly include the following points


1. Improve production efficiency

Through real-time monitoring and optimal control of the production process, production interruptions, failures, and waste products can be reduced, equipment utilization and production capacity can be improved, production cycles can be shortened, and energy consumption and costs can be reduced.


2. Improve product quality

Through precise adjustment and control of production parameters, it can ensure that the size, composition, performance, and other indicators of the product meet the standards and requirements, improve the consistency and reliability of the product, and meet the needs and expectations of customers.


3. Improve security

By timely discovering and handling abnormal situations in the production process, accidents can be avoided or reduced, the safety of personnel and equipment can be protected, and losses and risks can be reduced.


4. Energy saving and environmental protection

Through the monitoring, analysis, and optimization of the production process, energy consumption, emissions, and waste can be reduced, thereby saving energy and protecting the environment.


5. Improve management level

Through the collection, storage, analysis, and processing of production data, it can provide managers with valuable information and suggestions, help them make decisions, plan and evaluate, and improve management efficiency and level.


Development trend of level 2 automation in the steel industry

With the development of information technology and artificial intelligence technology, the secondary automation of the steel industry is also making continuous progress and innovation. The future secondary automation of the steel industry may have the following development trends:

1. Informatization and intelligence

Utilize technologies such as the Internet of Things, cloud computing, big data, and artificial intelligence to realize the collection, analysis, optimization, and decision-making of production equipment, process parameters, product quality, energy consumption, and other data, build smart factories and smart supply chains, and improve iron and steel enterprises level of digitization and intelligence.

2. Green and low carbon

Through the secondary automation technology, the monitoring and control of environmental protection measures such as pollutant discharge, waste utilization, and resource recycling in the production process can be realized, the ecological impact and carbon emissions of the steel industry can be reduced, and the green development and low-carbon development of the steel industry can be promoted. transformation.

3. Collaboration and innovation

Through the secondary automation technology, information sharing and coordination among various departments and processes within the iron and steel enterprise, as well as information exchange and collaboration with external partners such as upstream and downstream enterprises, scientific research institutions, and government departments, are realized to promote collaborative innovation in the iron and steel industry and industrial chain optimization.

To sum up, secondary automation in the iron and steel industry is a technology that uses computer technology to optimize the control of the production process, which can bring significant benefits and competitive advantages to iron and steel enterprises.

However, with the development of technology and changes in the market, the steel industry is also facing new challenges and opportunities. Level 3 automation – that is, based on level 2 automation, the production process is intelligent, networked, and digitized, and higher levels of automation such as level 4 automation can further enhance the competitiveness, innovation, and sustainability of the steel industry.

The iron and steel industry should rationally select and apply different levels of automation technology according to its own development goals and actual capabilities, so as to achieve more efficient, better quality, more environmentally friendly, and more intelligent production.
