Pilot cold rolling mill is the important tool for the cold rolling process researching and new steel grade development. According to the design of the new type direct pulling pilot cold rolling mill, based on the mass flow constant principle, strip exit thickness indirect measurement method is studied. During rolling, strip entry and exit speed can be calculated accurately according to the measured value of two sides’ clamps movement. Data filtering treatment is adopted and program flow chart is designed. Based on the material entry thickness measured manually, exit thickness of all passes can be measured indirectly. This thickness indirect measurement method has been applied successfully on the new type pilot cold rolling mill, and the measurement results show that this method has a good accuracy.

Crm Certification

Calibration is the operation establishing metrological traceability of values of calibrated measuring instrument scale (or reference material) to stated reference. In the case of indirect measurement it is necessary to know the relationship between determined quantity values and corresponding measurand values. If mathematic form of this relationship is unknown, it is substituted by its approximation. In this process a real situation is simplified by neglecting of influence quantities to a relation of two variables- independent versus dependent. Metrological traceability of certified reference materials (CRM) values intended for calibration purposes and characterised by means of a method working on the base of approximative function could be questionable. If a measurement method based on original relationship already exists, it should be strongly preferred in the process of CRM certification to methods based on approximation of original relationship.

Gas Consumption

At present, the remote meter reading problem for a large number of existing domestic diaphragm gas meters has not been reliably solved. The diaphragm gas meter uses a physical structure to measure gas consumption, so the main problem of remote meter reading is the digitization of gas consumption. Although it is possible to digitize the consumption data by modifying the internal structure of the gas meter or adding sensors, thereby realizing the function of remote meter reading, the modification process is complicated, the modification cost is high, and manual meter reading can only be used for the existing diaphragm gas meters. For this reason, this paper proposes an indirect measurement method of gas consumption based on gas pressure signal detection. The method can digitalize the metering results of the mechanical diaphragm gas meter and develop a state detection function by analyzing the pressure signal of the outlet of the meter without modifying the internal structure of a meter, thus addressing the key difficulties in the construction of a gas meter remote meter reading system. The experimental results show that this method has small calculation error and high reliability.
