Six times in four days, a new Winter Olympic record was born, and the "fastest ice" lived up to its name

Live Bar February 10 news "record-breaking" is definitely the key word since the start of the speed skating project of the Beijing Winter Olympics. As of yesterday, the speed skating event has been competing for four competition days, and the athletes have set a new Winter Olympic record six times. On the one hand, it reflects the athletes' efforts to continuously surpass the limit and pursue excellence, on the other hand, it also shows that the ice surface of the "Ice Ribbon" of the National Speed Skating Hall of the competition venue is worthy of the reputation of "the fastest ice".

It is understood that under the protection of "black technology" such as carbon dioxide transcritical direct cooling technology, the maximum temperature difference of the ice surface of the "ice ribbon" can be controlled within 0.5 degrees Celsius, laying a hardware foundation for high-quality ice surface. But if you want to have the "fastest ice", you can't do without the efforts of the ice-making team of the venue. Yesterday, although the competition was suspended for a day, the ice team of the stadium was not idle, "We came to the venue at 7:30 in the morning to monitor the ice situation, not only because there will be athletes to train today, but also the ice surface must be carefully maintained every day." Shao Yi, head of the ice-making team, explained.

For the ice team, ice monitoring is an important task, because as the temperature, humidity and even the number of people and landscape arrangements inside the venue change, the ice surface state will fluctuate. An important element of monitoring is the measurement of ice surface thickness. Shao Yi said: "Regardless of the straight or the curve, the thickness of the ice surface must be between 2.5 cm and 3 cm, so as to ensure flatness. Where the ice surface is thinner, the watering truck will sprinkle more water, and vice versa, sprinkle less water, and the ice knife on the car will shovel the ice and the knife will be deeper. He told reporters that in order to ensure the quality of the ice surface at all times, the "ice ribbon" race has been poured ice up to 8 times a day.

Such meticulous maintenance and adjustment have continuously improved the ice quality of the "Ice Ribbon". Dutch star Krul, who won the silver medal in the men's 1500m on February 8, said after the game, "The ice surface was adjusted very well, and today I felt like skating on the ice rink in my hometown. ”

Among the 18-member ice-making team, Maiser, a Canadian expert who participated in the ice-making work for the Winter Olympics for the sixth time, was the central figure. Shao Yi told reporters that Maiser is not only highly skilled, but also let him and the Chinese team members feel and learn the real "craftsman spirit", "He treats the ice surface like his own child, especially loving, and will never allow any unrelated personnel to go to the ice." When he saw an inconspicuous little black dot on the ice, he would immediately stop and deal with it. Shao Yi revealed that Maiser worked without reservation and passed on his skills to the Chinese personnel.

Next, the "Ice Ribbon" will also compete for 10 small items. Shao Yi and his team are very excited, "Now that everyone is full of energy, we will definitely be more meticulous, let the ice state get better and better, and look forward to more athletes, especially Chinese athletes breaking records here!" ”
