Publication number: 20250067488Abstract: An icemaker includes a casing that receives water from a water supply and is in thermal communication with an evaporator of a sealed system that chills the casing to freeze the water. An auger is mounted within the interior volume and is rotatable to scrape the ice from the casing and urge it through an extruder to form nugget ice. A BLDC motor is mechanically coupled to the auger to selectively rotate the auger. A controller determines a target speed of the auger based at least in part on the ice production parameter, and operates the BLDC motor to rotate the auger at the target speed. The BLDC motor with the speed-closed control loop can provide the constant speed and enough torque to prevent the ice maker from freezing. The controller can adjust the PWM and the voltage will be adjusted slightly, then the torque will be adjusted accordingly.Type: ApplicationFiled: October 20, 2021Publication date: February 27, 2025Inventors: Yayu Song, Bo Yan, Michael Zhou, Roy Teng, Jin Wu, Eddy Zhou, Shi Zhijun, Jason Jiang

Publication number: 20250043378Abstract: A high-strength steel with excellent neutral aqueous medium corrosion resistance, and a preparation method and application thereof are provided. A steel plate is designed with cheap chemical compositions of low carbon, low silicon and medium manganese, and is completely free of precious metal elements such as Cr, Ni and Cu, thereby greatly reducing the material cost. According to the present invention, instead of the traditional Al deoxidation technology, Si or Si—Mn deoxidation assisted by Zr—Ti composite deoxidation is used to form a fine, dispersed and uniform composite oxysulfide, which greatly decreases the density of corrosion-active inclusions, and obviously improves the neutral aqueous medium corrosion resistance. Through the design of low carbon equivalent, the steel plate has excellent welding performance; and the composite microalloying of Nb, Zr and Ti is adopted to cooperate with the TMCP rolling parameter control, so that the steel plate has high strength and good extensibility.Type: ApplicationFiled: February 7, 2024Publication date: February 6, 2025Applicants: WUHAN UNIVERSITY OF SCIENCE AND TECHNOLOGY, WUKE XINCAI (WUHAN) TECHNOLOGY CO., LTD., WUKE COMPOSITE MATERIALS (HAIKOU) TECHNOLOGY CO., LTD., SINO-ENERGY HUAYUAN FLOATING WIND INSTITUTEInventors: Kaiming WU, Shi CHENG, Shaoguan XIANG
