A multifunctional high temperature silicon molybdenum rod furnace tube viscosity measurement system and method

Abstract

The invention belongs to the technical field of viscosity detection of molten iron, slag and other substances, and discloses a multifunctional high-temperature silicon-molybdenum rod furnace tube viscosity measurement system and method; a corundum furnace tube is placed in the hearth of a silicon-molybdenum rod furnace, and a high Aluminum base, graphite crucible and sample are placed on the base, the integrated graphite probe is inserted into the sample, the probe passes through the corundum measuring rod driven by the rotational viscosity sensor to rotate in the sample to measure the viscosity value, the probe insertion depth is determined by the up and down moving motor on the bracket Positioning; the temperature of the silicon molybdenum rod furnace is controlled by the control cabinet and the temperature control thermocouple. The actual temperature of the sample is measured by the temperature measurement thermocouple. And data collection, and data processing to get the viscosity experiment results. The invention effectively improves the service life of the furnace tube, has higher concentricity and lower cost, and can adapt to the determination of most metallurgical melts.

Description

technical field [0001] The invention belongs to the technical field of viscosity detection of molten iron, slag and other substances, and in particular relates to a multifunctional high-temperature silicon-molybdenum rod furnace tube viscosity measurement system and method. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: the viscosity measurement system is used to detect the viscosity of molten iron, slag and other substances. The furnace tube used in the existing viscosity measurement system is a one-meter-long corundum tube. The probe is three Segment type, divided into connecting head, connecting rod and probe, the materials are molybdenum and graphite respectively. Existing high-temperature furnaces use integral corundum furnace tubes. Since the heating element of the furnace body is in the middle section corresponding to the corundum tube, the integral corundum furnace tube basically forms an uneven temperat...

AI Technical Summary

Problems solved by technology

The problem existing in the existing technology is that due to the large temperature difference between the top and the middle of the furnace tube, during the sampling process, the sample temperature is above 1500 ° C, which causes the upper part of the furnace tube to break when the equipment is measuring 4-6 furnaces, and when using 6-10 furnaces This furnace tube cannot be used

In addition, the overall cost of the three-stage probe is about 200 yuan, which is relatively high and easily damaged

[0003] To sum up, the existing problems in the prior art are: the problem in the prior art is that during the sampling process, the temperature of the sample is above 1500°C, which causes the upper part of the furnace tube to break when the equipment measures the 4-6 furnaces. The furnace tube cannot be used at 10 furnaces; the overall cost of the three-stage probe is about 200 yuan, which is relatively high and easily damaged

The middle connection part of the integrated graphite probe, that is, the diameter of the measuring rod is the key. If it is too thin, the strength cannot be guaranteed, and if it is too thick, the measurement accuracy of the probe will be reduced.
