The content of oxygen and nitrogen gases has a crucial impact on the properties of high-temperature alloys. They can cause defects such as shrinkage, bubbles, porosity, point segregation, cracks, etc. in steel, and also have their own unique effects on the properties of steel. Therefore, measuring oxygen and nitrogen gases is of great significance. Oxygen nitrogen hydrogen analyzer is a specialized equipment for detecting gas content in steel. It adopts pulse heating and infrared thermal conductivity detection technology, which can achieve rapid and accurate determination of oxygen, nitrogen, hydrogen elements in steel, metal powder, non-ferrous metals and other materials.
The carbon and sulfur content have a crucial impact on the mechanical and process properties of high-temperature alloys, therefore determining the carbon and sulfur content in alloy materials is of great significance. The high-frequency infrared carbon sulfur analyzer and high-speed carbon sulfur analyzer used by our company can accurately determine the content of carbon and sulfur in various alloy materials, and the detection limit can reach PPM level. In the daily analysis and testing process, according to the analysis standards, the carbon and sulfur detection data of the spark direct reading spectrometer can also be calibrated to ensure that accurate data can be quickly obtained for daily ladle carbon and sulfur analysis and finished product carbon and sulfur analysis, ensuring efficient and high-quality production promotion.

Roller body dynamic balance refers to a technology that achieves high rotational accuracy by coordinating the structure of the roller body during high-speed rotational motion. It is one of the important means to achieve high-speed, stable, and long-life operation of mechanical rotating structures. Poor dynamic balance of the roller body can lead to problems such as vibration, noise, and damage during equipment operation, thereby affecting product quality and production capacity. By controlling the dynamic balance of the roller body, vibration and noise during equipment operation can be reduced, equipment life can be extended, and production efficiency and product quality can be improved.
The roller profile meter can continuously measure the diameter changes in the length direction of the roller, and control the contour curve of the roller during the roller manufacturing process. In production, rollers usually have to be replaced within a predetermined period of time, or sometimes due to failure. This leads to an increase in costs. After using the roller shape gauge, the rollers can be replaced only when necessary, greatly reducing costs.
