In order to further strengthen the double metal band saw blade heat treatment process quality control, to effectively improve the qualification rate of products, in July, under the joint efforts of technical personnel and production personnel to complete the band saw blade quenching line on-line temperature alarm program design, and achieved significant results.

Band saw quenching line equipment is the core of the special steel products company production double constant equipment, its role is largely bandsaw quenching tempering integration, using nitrogen circulation cooling mode, the internal organization of band saw blade is more stable. Due to the equipment highly demanding to the stability of the temperature, the temperature deviation, once appear, will cause producing band saw splits caused, metallographic organization, the serious influence the quality of the product, just rely on production personnel patrol to monitor the temperature cannot be found in time and make the corresponding processing. In order to solve this problem, the special steel products company with the support from the device manager, technical personnel decided to use a band saw quenching line equipment on the configuration software, the design of a complete set of on-line temperature automatic alarm procedures, make the band saw temperature quenching line 33 temperature regions are under the control of the program, all the temperature value of temperature area will be displayed on the computer screen, no matter any temperature regions more than set temperature deviation deviation, band saw quenching line will automatically alarm, production personnel through a computer can find out the problem and handle in a timely manner, to ensure that the band saw blade in setting temperature range running smoothly.

After repeated experiments, band saw quenching line equipment temperature control automatic alarm procedures have been debugging success online, after more than half a month's trial is preliminary already reached band saw, the purpose of heat treatment temperature online monitoring is far better than expected goals. The design of this alarm procedure, effective implementation of the band saw quenching line each temperature zone temperature control, so as to improve the qualified rate of the band saw blade, to produce more high-quality products for the future and lay a good foundation.
