According to the “Daily Mail” report, on the evening of November 6, local time, a 25-year-old electrician fell into a round hole on the top of a furnace filled with molten aluminum at 720 ° C while working at a factory in St. Gallen in northeastern Switzerland. Speaking, he reluctantly pulled himself out of the stove and was rushed to the hospital. Under normal circumstances, the temperature above 70°C can cause the human body to be burned instantly.

Molten metal submerged up to the young man’s knees, but he fought back the pain and managed to pull himself out of the stove and crawl to safety, reports said.
At that time, the 25-year-old man was repairing the furnace with another colleague in the factory, but he accidentally fell into the furnace through the opening at the top, and the parts below his knees were all soaked in liquid aluminum as high as 720 degrees.
Fortunately, the man propped himself out of the furnace right away. The Swiss worker fell into the 720°C furnace and climbed out alive. The colleagues at the side immediately called an ambulance and gave first aid. After the paramedics arrived at the scene, they dispatched a helicopter to take him to the hospital for treatment.

Some netizens said that fortunately, the furnace was filled with molten aluminum, which has a low melting point of only 660°C, so the worker still had a chance to climb out.
If it is replaced by molten steel, the temperature can reach 1700°C, and a high-temperature zone will be formed around the molten steel. The water in the human body will boil rapidly, and there is no possibility of survival if it falls into it. A Swiss worker fell into a 720°C furnace and survived. I have to admit that the perseverance and reaction speed of this 25-year-old worker are impressive. It is definitely a miracle to be able to escape in the aluminum water!
Two Swiss emergency air rescue doctors and paramedics rushed to the factory to rescue him, and he was flown to hospital by helicopter with extensive burns all over his body.
St. Gallen police are investigating how the accident happened, and it is not the first accident at the factory. High Quality Custom precision precision CNC turning
Similar incidents have also been reported in the United States. In June this year, an employee of an iron foundry in Illinois, USA fell into a furnace with a temperature exceeding 1,000 degrees Celsius. .
Precautions:
The iron and steel industry is an industrial industry mainly engaged in industrial production activities such as ferrous metal mineral mining and ferrous metal smelting and processing, including ironmaking, steelmaking, steel processing, alloy smelting, steel bars and iron products, etc. sector.
Employees in iron and steel factories are mainly engaged in the production of “heavy objects” or work in contact with iron, aluminum, steel, etc., and are in contact with “dangerous” objects such as steel. Most of the ironmaking is smelted in blast furnaces, and some use direct reduction and electric furnace methods. Ironmaking. Dangerous and harmful factors are concentrated in the process of iron and steel smelting. Once an accident occurs, it will be more serious, and even casualties will occur. Therefore, personnel engaged in the iron and steel smelting industry must wear safety protective gear with anti-smashing, fire-proof, and high-temperature protection functions.
Before the steel is smelted out of the furnace, the operator may be burned by the smelting metal or slag; in the ingot workshop, the tipping or shaking of the steel drum will cause high-temperature liquid splashing, causing burn hazards to the human body; beside the furnace, workers stumble Slipping and falling may also touch hot metal; therefore, safety shoes for steel mill workers also need to be added with high temperature resistance and puncture resistance.

The iron and steel smelting industry should strengthen the learning of safety protection knowledge for operators and enhance personal self-protection awareness. At the same time, enterprises should also improve working conditions, strengthen preventive measures, and wear personal protective equipment during operations, such as anti-smashing safety shoes and fire-proof safety shoes , high temperature resistant safety shoes, protective clothing, goggles, etc., to reduce the degree of injury to workers caused by smelting accidents.
Speaking of this, I think of a moving picture of a fighting nation
Explanation from fan Chen Yunfeng: The physical principle of splitting molten iron with bare hands is the Leidenfrost phenomenon. The Leidenfrost phenomenon refers to the fact that when a liquid touches the surface of an object whose temperature is much higher than its own boiling point, the surface of the liquid immediately boils and a vapor layer is generated, which hinders the high-temperature object from continuing to transfer heat to the liquid, so the one who splits molten iron with bare hands Although there is no protection on human hands, there is still sweat on the hands. The “Leydenfrost phenomenon” occurs at the moment of contact between sweat and molten iron. The formed steam blocks the molten iron and palms, thereby avoiding burns.
Is this the reason why it won’t break quickly? Although you know the principle, don’t try it. High Quality Custom precision precision CNC turning
