　　Installation, commissioning and operation procedures for WY12-HW2000D arc infrared carbon sulfur analyzer
Understanding how to install and debug the WY12-HW2000D arc infrared carbon sulfur analyzer, proper maintenance and use of the infrared carbon sulfur analyzer are very important, as they directly affect the future use of the instrument. The following will explain in detail, mainly divided into two aspects.
1. Installation of high-frequency furnace for infrared carbon sulfur analyzer
After purchasing the WY12-HW2000D arc infrared carbon sulfur analyzer, we first opened the packaging box, took out the instrument, used a screwdriver and adjustable wrench to remove the instrument's rear cover plate, and then removed the right side plate. On the right side of the instrument, we used a screwdriver to unscrew the inner cover plate and remove the core of the high-frequency part of the high-frequency furnace. Fix one end of the vacuum capacitor to the bottom plate of the movement with screws. The other end is fixed to the capacitor and heating coil with a connecting copper sheet, and then the fixing screws of all components on the movement are tightened with a screwdriver. Put the movement back in its original position, remove the electronic tube and insert it into the socket, and tighten the screws such as the upper radiator and copper strip. Use a wrench to remove the skin tubes from the oxygen inlet joint and furnace gas joint on the furnace head, unscrew the fasteners by hand to remove the furnace chamber, and place the quartz tube into the furnace frame from above, passing through the induction coil in the middle of the furnace frame. The upper end of the quartz tube will be removed and the furnace chamber will be installed as it is. The lower end of the quartz tube is fitted with a red silicone gasket coated with vacuum silicone grease. Check for loose internal screws and any other unrelated debris inside the chassis. Finally, fix the movement, fixing screws, and inner cover plate screws, and install the right side plate and rear cover plate. So the high-frequency furnace is installed.
2. Installation of the detection part of the infrared carbon sulfur analyzer
Open the packaging box of WY12-HW2000D arc infrared carbon sulfur analyzer, remove all components, and place them according to the external structure. Open the top cover of the infrared detection device, check if the printed circuit board and various connectors are loose, reinsert these components, and then restore them to their original position. Connect the power supply, various gas pipelines, and connections.
3. Debugging part of infrared carbon sulfur analyzer high-frequency furnace
The above is the installation instructions for the infrared carbon sulfur analyzer. Now, let me share the debugging part with you. There are no difficult points in the debugging part. Generally, the instructions for installing the WY12-HW2000D arc infrared carbon sulfur analyzer are sufficient for operation. However, it should be noted that the carbon zeroing process needs to be fully adjusted, while the sulfur zeroing process generally does not need to be fully adjusted.
　　Sampling and steps for analyzing various materials using a high-frequency infrared carbon sulfur analyzer
High frequency infrared carbon sulfur analyzer is used to analyze cast iron and low, medium, and high alloy steel. Firstly, the pig iron, low alloy steel, or stainless steel channel is selected, and the instrument is calibrated. Then, a sample (about 0.250g for iron and about 0.500g for low alloy steel and stainless steel) is weighed into a crucible, and 1 tablespoon (about 1.2g) of tungsten particle melting aid is added. It is placed on a high-frequency furnace for combustion, and the computer automatically calculates the carbon and sulfur content in the sample. The measurement results are shown in Table 1. The RSD results show that the carbon content of pig iron BH2033-1 is 0.882, while the carbon content of plain carbon steel 26-1 is 0.0882 and the sulfur content is 2.69.
　　Analysis of Coal and Coke by High Frequency Infrared Carbon and Sulfur Analyzer
The analysis step is to first select the coal or coke channel and calibrate the instrument. Then weigh 0.500g of pure iron and place it at the bottom of the crucible. Place about 0.050g of the sample on top of the pure iron. Finally, add a spoonful of tungsten particles to the surface of the sample and burn it in a high-frequency furnace. The computer will automatically calculate the sulfur content in the sample. The standard value of coke 82-4 is 0.97Ao, with an infrared analysis value of 0.98. The standard value of coke 82-3 is 0.81Ao, with an infrared analysis value of 0.81. The standard value of coal is 2.65, with an infrared analysis value of 2.64. Analysis of Ferroalloys
First, select the channel of the ferroalloy and calibrate the instrument. Then weigh about 0.100g of the sample and place it in a crucible. Add tungsten particles, molybdenum trioxide, No.1 flux or pure iron as flux, and burn it in a high-frequency furnace. The high-frequency infrared carbon sulfur analyzer is matched with a computer to automatically calculate the carbon and sulfur content in the sample.
