1 Repeatability deviation of measurement results According to the working principle of our instrument, carbon element is measured according to the national standard method of gas volume method. The principle is to use the volume of carbon dioxide gas produced by combustion to measure the product content. 3 Carbon and sulfur analyzers Sulfur table display The speed is slow, the speed of return to zero is slow. The data displayed by the sulfur meter is controlled by the pressure sensor and belongs to a high-precision display. Data bounce is a normal phenomenon in the process of adding liquid. The problem of slow return to zero depends on the reference. How slow the slow in the end, if you need more than 15 seconds to be stable, you can check the burette rubber plug slot is blocked, if within 15 seconds is normal, it is recommended that the buret above the rubber stopper slot open large a little. This type of problem can be avoided.
2 silicone ring, quartz tube excessive damage silicone ring is a consumable product, arc furnace combustion temperature can reach 1800 degrees, damage is a normal phenomenon, if excessive damage is recommended to control the sample frequency, you can also through the cooling treatment (open the "before the oxygen "Cool the furnace with a damp rag to cool down.
The quartz tube is also a consumable product. Excessive damage can adjust the distance between the quartz tube and the sample, generally equal to the inner circle of the electric arc furnace.
IV. The amount of silicon molybdenum powder and tin is not fixed. The total amount to be added is about 0.3g. Use a small stainless steel spoon to dig 20%-30% of silicon molybdenum powder and tin particles.
4Sample problems General general steel is 1g, raw, cast, ductile iron is between 0.5-0.25g. The specific method of discrimination is 3.0% of the following carbon content can be called 0.5g, 3.0 or more of the proposal is called about 0.33g. Generally, we recommend 0.33g because we are a rapid analyzer, and the air extraction process is only about 8 seconds. In order to make the sample fully burned, try to avoid excessive samples, resulting in non-uniform combustion.
5 The volume of gas is directly related to the temperature. Therefore, according to our judgment, it is recommended that your company technician should pay attention to the frequency of the sample when it is done. It is best to control the time before the furnace. Avoid first weighing all the samples in order.
