In the second phase of Grand Sky II in Ningbo Middle Road of Ningbo City, Zhejiang Province, two consecutive natural gas leaks occurred, one of which caused an explosion. Fortunately, one person suffered only minor injuries. At 20:37 on February 18, the Ningbo Yuzhou Fire Brigade received an alarm that the second phase of the Grand Skylight had leaked and exploded. Immediately after receiving the alarm, 15 firefighters were dispatched to the rescue. At 20:52, it was discovered that broken glass and doors and windows were found downstairs. The room was exploded. The balcony and door collapsed, and all windows and doors in the north and south were slammed into the opposite side of the window frame and smashed into the four cars in the community. According to Mr. Shi, the neighbor, everyone was already asleep and suddenly heard a loud noise. The whole building was vibrating. They came out and saw that it was an explosion next door. Then they immediately started to self-rescue and warn. The head of the household is a foreign businessman named Dave. According to Dave, the incident smelled like natural gas at the time, but he didn't care too much about cooking. The rice exploded in less than two minutes after the rice had been cooked. Fortunately, Dave was watching TV in the living room. There was a wall blocking the blast and the staff was slightly injured. According to Dave's translator, Miss Wang, although Dave has lived in China for 2 years, he does not know much about Chinese. He also tried his own attention to the use of pipeline gas. Fortunately, this incident did not cause much damage. We remind foreign friends here that if you come to Ningbo for a long period of time, it is best to fully understand gas and electrical equipment that can cause accidents, and ask local friends for on-site guidance. After all, the situation varies from country to country, and if there are foreign guests coming here, We hope that everyone can do a good job in guiding related work in advance to avoid accidents. And at 22:59 on the same day, Luzhou Fire Brigade received an alarm: There was a natural gas leak at the 259th of Grand Sky II. When the firefighters arrived at the scene, the gas company's repair personnel had repaired the leaked pipeline. According to Mr. Qiu, the owner of the house, his wife smelled the smell of natural gas at 19 o'clock and immediately turned off the gas and power supply. However, as soon as Mr. Qiu came back at 22:00, the natural gas smell was very strong and he immediately called the police. It is understood that these two natural gas leaks are caused by the aging of valves and pipelines. The fire department reminded the general public that natural gas and gas have unique odors. If you smell odors, don't turn on the lights, make phone calls, rub the clothes, etc. Once the gas reaches the explosion threshold, a little ignition star will cause an explosion.

Ferroalloys, a
broadly defined ferroalloy is a product that is used as a deoxidizer, elemental
additive, etc. in steelmaking to add iron to certain properties or to meet
certain requirements.
Property: The main element of the ferroalloy generally
has a high melting point, or its oxide is difficult to reduce, and it is
difficult to refine the pure metal. If it is together with the iron, it is
easier to reduce the smelting. The use of ferroalloys in iron and steel
smelting, in which iron is not only harmless, but because of the fusing of
molten steel is more favorable. Therefore, deoxidation and alloying in the
steelmaking process are mostly added in the form of iron alloys. Iron alloys
are generally brittle and cannot be used as metal materials.
Purpose: As a deoxidizer for steelmaking, silicon
manganese, ferromanganese and ferrosilicon are the most widely used . As strong
deoxidizers, aluminum (aluminum iron), silicon calcium, silicon zirconium, etc
are used . Commonly used alloy additives
are: ferromanganese, ferrochromium, ferrosilicon, ferrotungsten,
ferromolybdenum, ferrovanadium, ferrotitanium, ferronickel, niobium (neodymium)
iron, rare earth iron alloy, ferroboron, ferrophosphorus and so on. A variety
of ferroalloys, in accordance with steelmaking needs, are regulated in many
grades based on the content of alloying elements or the level of Carbon
contained, and the impurity content is strictly limited. Ferroalloys containing
two or more alloying elements are called composite ferroalloys. The use of such
ferroalloys can add deoxidizing or alloying elements at the same time, which is
beneficial to the steelmaking process and enables the more comprehensive and
efficient utilization of symbiotic ore resources. Commonly used: manganese
silicon, silicon calcium, silicon zirconium, silicon manganese aluminum,
silicon manganese calcium and rare earth ferrosilicon.
