Recently, the entire Shanghai has pressed the pause button. During the lockdown period, employees of Yuzhong Technology Shanghai worked from home and did not slack off due to the epidemic Effective cooperation in front of us, each performing their own duties, overcoming difficulties together, and quickly helping clients solve difficult problems in their work.

Due to the closed management in Shanghai, we are unable to provide on-site services. Our engineer Yin Pengfei provided remote guidance to our cooperative client, Kenas Taili Metal (Shanghai) Co., Ltd. (hereinafter referred to as Kenas), during his work from home to solve equipment failure problems and ensure the normal operation of the client's laboratory.

Kennametal Metal (Shanghai) Co., Ltd. is a Sino foreign joint venture established in May 1985 and was controlled by Kennametal, a US listed company, in 2012. We mainly produce and sell wear-resistant, corrosion-resistant, and high-temperature resistant hard surface welding materials, products, and hard surface processing products. The products are widely used in various industries such as aviation, automobiles, ships, forestry, mining, nuclear power, thermal power, petrochemicals, plastics, etc. The main products rank first domestically and are exported to Europe, America, Japan, Southeast Asia and other places. The product quality is comparable to similar international products. Kenna is committed to expanding its market, improving and innovating, leading the way in product development, and continuously strengthening its comprehensive strength in both domestic and international markets. Kenna is able to maintain its competitive advantage and sustain efficient development through advanced technology, stable products, high-quality services, and a comprehensive and rigorous management model.

The Rigaku X-ray fluorescence spectrometer ZSXPrimus IV in the Kenner Laboratory was found to have a malfunction alarm when starting the chiller. The initial diagnosis was that the cooling network was blocked. After cleaning, the fan could be manually started, but after being linked with the equipment, it could not be started. After analysis by Yin Gong, the staff assisted in measuring the motor and fan, and ultimately found that the current transformer was damaged. Fortunately, Kenna had a backup transformer. Due to the mismatch of the current transformer, Yin patiently guided the staff to modify the transformer, successfully completing the equipment maintenance and restoring normal use.

The Rigaku upper irradiation X-ray fluorescence spectrometer ZSXPrimus IV uses a new type of spectral crystal, which greatly improves the sensitivity of light element analysis (such as C, B), saves vacuum time, and is suitable for small sample analysis in micro area analysis. FP analysis without standard samples can accurately analyze without setting test components This is extremely important for the production of Kenna products, as it can effectively control the quality of each batch of furnace numbers with the help of this X-ray fluorescence spectrometer. Without this X-ray fluorescence spectrometer, the products cannot be produced normally, affecting market supply and downstream industrial production. Considering the urgent situation of the customer, our engineer Yin Pengfei prepared a contingency plan as soon as he received the customer's repair call to solve their problems.

During the period when employees of Yuzhong Technology Shanghai worked from home, for us, the bedside table may be our job, and the TV at home is the company's monitor. Although the work environment has changed, our work attitude has not changed. We still maintain an unwavering attitude, relying on online platforms such as WeChat and DingTalk to ensure that all work is not disconnected. Our employees work together to serve our cooperative customers and build a strong fortress for epidemic prevention and control.
