Mixed metal wire wire detection method


Ministry program is designed to achieve automatic detection and identification mixed silk, silk mixed design analysis of fixed analyzer program. As the dry reed relay pull time of about 10ms,[link widoczny dla zalogowanych], the bandwidth of the amplifier coupled mV and filter time constant of the network and other factors, software design instruction in the strobe relay 200ms after the time delay to ensure that measurement data accurate, but also has given the anti-pulse _ interference. All about 0.8K bytes of program, curing in a 2716, the program flow shown in Figure 2. After boot, when mixed with silk apparatus in the analysis of fixed temperature on the heating block stage, it is through PIO1 the PA. The output of the \machine's digital display temperature of the heating block, on the other hand the heating indicator light. to indicate their work status. When the heating block temperature rose to 150C, they will automatically stop heating wire in Figure 2 mixed analysis of computer flow chart given instrument (the turn on page 3 WANG Lian Hong and other computer controlled tensile testing machines indicate error conditions. (1) labeling of range, the input of steel, heat number and the number exceeds the limit curve. (2) Serial communication error. (3 ) printer problems. (4) STD bus industrial control computer error. did not turn on the power; communication line failure; serial communication port failure. (5) sensor not connected. (6) is not found or the technical conditions of the steel . (7) other errors. 6 Conclusion (1) using computer-controlled tensile testing machine, tensile testing machine makes it more reliable, more accurate data collected to meet the production, testing and research needs. (2) management process established, the value of the properties of the metal material inquiry, statistical analysis established a foundation for the value of the properties of the solution provided for convenience. (3) application of computer system, the system error and precision error than the conventional test method to improve nearly a thousand times. the modern computer used in industrial production, in terms of business efficiency or social point of view, the significance is huge,[link widoczny dla zalogowanych], but also the inevitable trend of modern industrial development. Received :1997 -10-08 (on the next p. 34) steel is mainly due to the crack surface: steel plate rapid cooling rate after rolling, the cooling intensity is too large and uneven, in addition to internal and external temperature difference in thickness crack in Figure 3 Fracture surface of 1000 × at large, phase change time, resulting in a strong linear and volume shrinkage inconsistency. formed a strong stress, accelerated after rolling plate cracking. In addition, because the steel is a high strength martensitic stainless steel, are particularly sensitive to temperature change, at high temperatures plastic zone is poor,[link widoczny dla zalogowanych], a larger thermal stress, cooling rate too fast to speed up the local stress concentration, the stress exceeds the ultimate strength of the material and the yield limit, resulting in the formation of different parts of the rolled steel plate crack or cracking. 4 Conclusion and measures steel plate lead to the surface after rolling crack, chip cooling rate after rolling too fast, due to the cooling intensity is too large. Therefore, ① slow cooling after rolling. rolled steel sheet immediately after the slow cooling into the environment, the cooling stacking insulation. ② temperature cooling. is strictly prohibited cooling after rolling board. implementation of the above measures, the steel surface quality is better,[link widoczny dla zalogowanych], no cracks and crack defects, fully meets the requirement. Since 1998, the date of closing of a lotus o1.15 (on the next page 26) into the detection of mixed silk stage. First, the input wire from the dial switch root number,[link widoczny dla zalogowanych], the program strobe analog switches, detection circuit connected, and then by the three keys switch K, Kz, transmission network material selection, test press K when Ni-A, detection of stainless steel A press when the detection of iron will press Arab. and then through the program can be transferred to the corresponding query to determine procedures for mixed wire. When it detects a mix of silk, through the PA ~ PA PIO2 mixed silk output alarm signal, indicating The wire material mixed, through SBC LED digital display on the serial number of the silk, silk mixed for the operator the location specified for replacement. If operators want to detect when a wire then be carried out replacement treatment, you can press the \Test completion, the PA-bit output by PIO1 end \795 and other military aviation in the production of Agra, lm wide, Argentina and more than 8,000 around the root wire can be detected only lh complete. extremely high precision, it can be said as long as the detection of mixed silk almost 100. more convenient to use to avoid the wire caused by mixing scrap wood or even Arab oil filter fault plane, creating a considerable economic benefits. closing date :1998 lotus -02-15
