Preface:

As the only manufacturer, specialized in the production of metal card clothing in Shanxi Province for the national textile enterprises provide a good card clothing configuration services, is our sacred duty. The company now has new flat clothing, new type metallic card clothing, reed, star brand welding electrode, often rising brand pure cotton socks five kinds of products. Existing fixed assets of 50 million yuan, all kinds of technical personnel account for 35% of the total number of employees. Especially in the introduction of Italy's new flat clothing production equipment and technology, the matching of metal card clothing class must also be improved. As the first line of heat treatment process of metal card clothing production process - well type annealing furnace technology is very important. Process control is proper, stable or not, directly affect the quality of metal card clothing products and using effect. At present, the domestic card clothing manufacturers are using external heated vacuum furnace, vacuum filling nitrogen and hydrogen after heat treatment, all manual operation each control links, such as inflated and deflated, temperature, time control, fan open, pumping air into vacuum state, current monitoring, temperature curve drawing, etc.). Relative operating strength increase, especially the quality of the product can not be stable, accurate and speedy access to monitor. The company through reasoning, in many ways determined and used by the computer to automatic monitoring of pit type furnace, through experiments, the effect is obvious. Introduce the following, in order to explore analysis.

Second, the well type annealing furnace computer automatic monitoring system is introduced:

This system mainly through the computer setting process, and control the operation to achieve well type annealing furnace process to meet the process requirements. At the same time, change the traditional manual operation.

(a) hardware system:

Mainly by the display, host, printer, manual work station, line control panel. Controlled by the sensors, solid state relay, silicon controlled rectifier, etc.

(2) of the software system:

The software system consists of three parts.

Above is on the computer before annealing results, visible:

Poor hardness between 170-210, for 40 points, hardness level between 2.5 4.

Time: on February 20, 2001 steel wire: Φ work no. : 1.45 01 steel grade: 72 b

Test results of the above two table is on the computer after, visible: hardness between 170-195, poor for 25 points, hardness level between 3-3.5.

2. Before computers on a steel wire have individual decarburization or outside hardness is on the high side. After installing microcomputer, because in the process was improved, the computer monitor sensitive, oxidation decarburization no longer exists.

3. The colour and lustre is also by the previous gray, light blue to white, to bright annealing.

4. In the gas process, we change previous H2 and N2, only use protection in H2. Role is one of cost saving, changing work environment, the second is the H2 high purity 99.99%, avoid trace oxygen in N2 reaction with steel wire in the oven.

5. The temperature curve, according to previously can only display the first paragraph, you can now three sections of the whole show. Can be intuitive analysis of each temperature, time control, provide reference for quality control.

6. Set the overtemperature alarm, such as the set temperature is 720 ℃, temperature appear outside the scope of overtemperature in 6 ℃, automatic alarm and prompt treatment.

7. Equipped with manual operation system, to prevent the occurrence of fault when using computer.

General test, the effect is feasible. Quality is greatly improved, economic benefits and social benefits are improved. Is that existing in current main parts of the hardware circuit parts quality closes nevertheless, service life is short, to improve. I company of the original 75 kw well type annealing furnace has been transformed, controlled by computer. For the metal card clothing constantly improve product quality, let us work together hand in hand, the application of high-tech technology to production, realize the whole process automation, service for textile enterprises to provide better and higher!
