Our company development is always guided with Kazuo Inamori's philosophy, including social responsibility. The philosophy is the regulations and agreements which constitute our company's standards. Incorporated in this factor are the rules and morals advocated within the company to reflect these management standards. Just as human beings have personal character, companies also have corporate character. The way to gain trust and respect from society is for company's character to be so impressive that people say, that is indeed a company with an admirable corporate character. Being profitable is neither shameful nor unrighteous. A price that is determined through free-market competition are a fair price, and the profit earned is a just profit. Fierce competition promotes rationalization, while raising added value increases profit, we persist in doing business fairly, pursuing a fair profit and contributing to society. Cherish the mutual trust that ties us together like a family, sharing the joys and sorrows of others as our own. This is the basis that connects all employees. Family-like ties make employees appreciate and care for one another. This trusting camaraderie is the basis of our working relationship. Like a family, employees help each other unconditionally when someone is in need, and give comfort even about personal matters. People have no higher calling than to strive for the greater good of humankind and society.

What is the difference between type K and N thermocouple

What is the difference between type K and N thermocouple

The accuracy and reliability of thermocouple largely depend on the thermoelectric uniformity and stability of thermocouple material. In order to obtain the best results in temperature measurement , not only attention should be paid to the structure, installation and calibration of thermocouple, but more attention should be paid to closely combining the temperature measurement site, working conditions, temperature range and the measurement accuracy can be used to select suitable thermocouple with higher stable thermoelectrics. Type K thermocouple has better comprehensive performance among base metal thermocouple. However, when it's used at high temperature for a long time, due to the change of alloy composition or the transformation of elements in the process of neutron radiation, the composition is uneven, causing a slow drift of thermal potential. When heated in the 250-650°C range, the poor repeatability of the thermopotentials (orderly and disordered transitions) caused by the uneven short-range ordering of the atomic lattice of the nickel-chromium KP alloy affects their accuracy. The magnetic transformation of the nickel-silicon (KN) pole in the range 150-260°C also causes fluctuations in the thermopotential. Type N thermocouple not only can avoid these weaknesses of type K, but also has stronger high temperature oxidation resistance, wider temperature measurement range. 1. Composition and Properties of Thermocouple Alloy 1.1. Chemical Composition of Thermocouple Alloy The positive of N-type thermocouple is the same as the positive of the K-type, which is Ni/Cr/Si alloy, but the content of chromium and silicon in the positive of N-type is increased compared to the positive of K-type. Because of the increase of chromium content, the aging effect of type K in the range of 400 °C and 600 °C is eliminated. Nicr alloy with Cr content of 14%~16% has the smallest room temperature resistance change, and the short-range order transition and spin phenomenon in this composition range are small. The effect of Cr content on the thermoelectric potential stability of Nicr alloy is shown in Figure 1. The purpose of increasing the silicon content is to improve the high-temperature oxidation resistance, so that the oxidation mode of the nickel-chromium alloy is changed from internal oxidation to external oxidation, making the oxidation reaction is only carried out on the surface. The effect of Si content on the thermoelectric potential of Nicr alloy is shown in Figure 2. Figure1 Figure2 Compared with the negative of type K thermocouple(KN), the negative of N-type(NN) increases the content of silicon and magnesium, but does not contain manganese and aluminum. The effect of adding magnesium is to prevent the silicon under the surface from being preferentially oxidized into silicon dioxide from the hot electrode. Increasing the content of silicon without manganese and aluminum completely improves the high temperature oxidation resistance of the negative...
