1. Low -pressure oxygen tube negative pressure and oxygen gun spray holes are blocked. They are easily recovered by the gas pour of the gas generated by high temperature melting ponds, and an accident occurs. Therefore, oxygen pressure should be tightly monitored. When multiple stoves are oxygen, do not rush to use oxygen to avoid causing pipeline recovery.
2. The raw materials, semi -finished products, and finished products needed during the steelmaking process of the square tube requires transportation equipment and locomotives for transportation. There are many risk factors in this process. Therefore, when designing the factory, consider sufficient space, pay attention to equipment innovation, and strengthen maintenance. It is also necessary to improve the operational level of workers and strictly abide by the production safety regulations.
3. The slag at the bottom of the steel, iron water, steel residue, and steelmaking furnace is high -temperature melting, and it will explode with water. The main measure of preventing melting in the water explosion is that the cooling water system must ensure safe water supply, water quality should be purified, and no leakage must be leaked.
4. The oxygen tube curve or variable diameter in the upper part of the oxygen gun Due to the large flow rate, the local resistance loss is large. If there is residue or absence in the tube, it is easy to induce high -purity, high pressure, and high -speed oxygen. In the production of square pipes, we should avoid accidents by improving design, preventing rapid bending, slowing flow rate, regular blowing pipes, cleaning filters, and improving abandonment.
5. The temperature of iron, steel, and slag is very high, strong heat radiation, and easy to splash. In addition, the temperature of the equipment and environment is very high, which is very easy to cause burns. Therefore, we must regularly check and maintain equipment such as steel refining furnaces, steel tanks, iron cans, mixed iron furnaces and other equipment. At the same time, pay attention to improving safety technical procedures and strict implementation, and do a good job of personal protection. The flanges and valves that are prone to air leakage should be replaced regularly.
6. Due to operating errors, the oxygen gun is not connected. The hypoxic water accumulation vaporizes at the high temperature of the molten pond to prevent high pressure water from entering. When the steam pressure in the oxygen gun is higher than that of the gun wall strength, the time varies. When dealing with such problems, you should be more cautious to avoid operational errors.
7. The structure of the steelmaking plant should be considered in the production of the square tube. There must also be a spacious operating environment. The ventilation and lighting are good, which is conducive to heat dissipation and discharge of flue gas. It is necessary to fully consider the safety requirements of personnel during work.
