The CS series high-speed carbon and sulfur analyzer developed by Nanjing Kirin Scientific Instrument Group Co., Ltd. is widely used in steel, metallurgy, foundry, mining, construction, machinery, electronics, environmental protection, health, chemical, electric power, technical supervision and other departments and colleges. , deeply loved by the majority of users.
Pay attention to the following points when operating the CS series high-speed carbon-sulfur analyzer:
1. In the carbon-sulfur analyzer, the electric arc furnace should use high-purity oxygen to assist combustion. The use of oxygen must be carried out in accordance with the safety regulations for the use of oxygen.
2. After connecting the power cord, you must use the test pencil to check whether the socket and the housing are energized. If the socket is live, the phase and neutral of the power supply should be exchanged and then tested with a test pencil; if the housing is extremely charged Should be connected to the ground wire. It is important to ensure that the electric arc furnace is operated without the charge of the electric arc furnace and the housing.
3. After the electric arc furnace of the carbon-sulfur analyzer is operated, the temperature of the furnace body, the crucible and the crucible is high, and do not touch them by hand to avoid burns. At the moment when the arc button is pressed, the combustion system must not be touched.
4. When using the furnace, adjust the gap between the ends of the electrode rods (4-8mm) according to the current meter on the panel. If you press the "arc start" button, the ammeter reading is very small or no reading, which means that the gap between the sample and the sample is too large, then the electrode should be pulled down a little. It is found that the ammeter reading is too large or exceeds the limit range, and there is no vibration sound, indicating that the pole has zero gap to the sample (that is, the pole is short-circuited with the sample), and the pole should be adjusted upward.
5. When the furnace needs to start the arc under normal use conditions, as long as the “ignition arc†button is pressed momentarily, the hand can be released and the sample can be ignited at high speed. If it is pressed several times and cannot be ignited, check the gap between the pole and the sample. It is forbidden to press the “Arc Start†button for a long time to avoid burning the circuit components.
6. When operating the furnace, the “pre-oxygen, post-control gas†process must be used for the pneumatic system. The oxygen pressure is adjusted to 0.04mpa to adjust the flow rate to 100 liters/hour. The oxygen supply system is connected to the inlet of the furnace by an oxygen cylinder through an oxygen pressure reducing valve or a low pressure oxygen gas connected to a low pressure gas storage tank (without water pressure). Remember to use an oxygen supply method that does not comply with this regulation.
7. In case of unstable test, the airway leakage test can be carried out by the pressure difference method of the communicating device. If it is found that there is air leakage in the airway, the “pre-oxygen†switch can be turned on to make each gas path and the combustion part oxygenate. Then apply soapy water to each sealed joint and rubber hose joint to check for leaks and correct them.
8. The furnace is equipped with a preheating device, which is controlled by a preheat button switch. The switch is turned on and the preheat indicator is on, indicating that the preheater is turned on. In normal continuous operation, 2-3 samples should be burned to increase the temperature of the crucible to 60-100 ° C. Turn off the preheat switch and test it (do not remove the preheater); When it is too high, use a wet towel to cool the sley; when it is used intermittently (test before the furnace), turn on the preheating device, and the squat can obtain the pre-heating effect (60-100 °C).
9, in the furnace body cavity filter copper mesh, dust collector and other places too much dust will hinder the test stability, the application of a small brush to remove. You can also use the leather tiger to blow off the dust. Generally, do 30-40 samples. The dust should be cleaned once. When the dust remover removes the dust, you should pay attention to whether the dust paper is intact. If there is damage, please replace it in time, otherwise the dust will pass through the single tube. (Secondary dust removal device), the flow meter and the back control valve enter the sulfur absorption cup to prevent the sulfur from being measured, and the flow meter and the back control valve may be out of order.
10. Carbon-sulfur analyzer When the electric arc furnace is used to burn carbon and sulfur samples, it is recommended to use tin particles and silicon molybdenum powder as additives. For every 1 gram of sample burned, about 0.3 grams of additive should be added. The slag should be dark gray. If it is bright, it means that the tin particles are too much, and the sulfur measurement result may be low.
