Intelligent measuring instruments for geometric dimensions bring economic benefits to steel mills

The quality inspection of wires, bars, pipes, plates and other products is inseparable from the inspection of some basic geometric dimensions. With the improvement of production line automation, more and more production lines are beginning to use intelligent measuring instruments. This is not only because it can bring about quality improvement but also the economic benefits.

There are many types of geometric dimension intelligent measuring instruments, among which the basic ones include online diameter measuring instruments, online straightness measuring instruments, width measuring instruments, thickness measuring instruments, length measuring instruments, profile meters and other types of equipment, all of which can realize intelligent online detection. , while testing the quality, it can also analyze and store the testing data.

1. Discover defective products in a timely manner

Online monitoring can detect substandard products in time, thereby adjusting the production line in a timely manner and reducing losses caused by mass production of corresponding substandard products. If the production line has automatic control equipment, real-time detection data can also be transmitted to the control system to achieve closed-loop control. Improving the advantages brought by online inspection will also reduce the huge losses caused by untimely detection of defective products, especially in high-speed production lines.

According to statistics, a high-speed line with an annual output of 800,000 tons can reduce the amount of scrap by: 80×0.3%=0.24=2400 tons; the price difference between finished rolled materials and scrap rolled materials is about 1,000 yuan/ton. After installing the caliper, every year The benefits created are 2400×1000=2400000=2.4 million yuan. Other geometric size measuring instruments bring different cost savings depending on the production line situation.

2. Reduce production failures

In an automated production line, unqualified dimensions may cause collision, wear and other damage to the production equipment. In mild cases, it can be continued to be used, but in serious cases, production may need to be stopped for maintenance. Equipment failures caused by this type of equipment can also be treated. Save huge economic benefits.

According to statistics from the manufacturer of the caliper, after installing the caliper, the output of each high-speed line due to production accidents is reduced by about 0.05%. Calculated based on a production line with an annual output of 800,000 tons: 80×0.05%=0.04=400 tons; The price of finished rolled products is calculated as 3,500 yuan/ton: 400*3500=1.400000=1.4 million yuan. Similarly, different combinations of smart measuring instruments and different production lines also bring varying degrees of cost savings.

3. Real-time monitoring of product quality

An intelligent measuring instrument can comprehensively detect quality information. It is not only faster than manual inspection but also more comprehensive and accurate than manual inspection. There is no need for too many measuring personnel. One person can be responsible for simple operation, maintenance and analysis of the production line, reducing manpower. Reduce costs, reduce employees' jobs in harsh environments, optimize and improve the company's professional and information management level, and greatly improve the company's production efficiency.

4. Effectively reduce equipment after-sales maintenance costs

Online real-time monitoring can help reduce hidden faults and extend use and service life. It will also reduce the backlog of repair parts inventory costs and reasonably control unnecessary expenses, which will be a considerable net profit.

In short, the advantages that intelligent online measuring instruments bring to production lines are irresistible to all manufacturers and are also the development trend of future production lines. Not only the use of geometric size measuring instruments but also various types of measuring instruments will be used. to their respective fields.
