| Hot air valve position in high temperature region, the downtime maintenance of hot air valve flange region on both sides of the temperature is 750 degrees Celsius, flange replacement is difficult hydrosphere maintenance work, through the discussion and analysis of two kinds of hot air valve flange hydrosphere online replacement scheme, proposed replacement scheme for an online security and stability, simple and efficient.
Rotary Tube Furnace with vacuum flanges and valves
Hebei Iron & Steel Group Company of small blast furnace hot blast system using circulating water cooling both ends of the flange, the flange connecting part to prevent overheating and deformation, Water Leakage failure occurred in the production of flange in the hydrosphere, need repair during the replacement of the flange ring. Due to the actual factors of the high temperature in the field, it brings great difficulty to the maintenance, and it is also the key project of the maintenance personnel. The main difficulty of maintenance of hot air valve flange ends after Hugh temperature up to 750 DEG C, the safety and reliability of the site is low, thereby affecting the maintenance efficiency; secondly inside the flange and pipe is a refractory brick layer orderly distribution, demolition after destroying the internal flange ring brick layer, difficult recovery; maintenance mode finally routine operations for a long time. Effect of blast furnace after the resumption of production and stability. Through a long time of the project research, compared with the conventional maintenance mode, through practice to verify a safe and efficient online replacement scheme for hot blast valve flange ring. Hot air valve and flange ring distribution.Resistance vacuum carbonization butch furnace for sintering alloy
The past is the disassembly of hot air valve flange for replacement of the hydrosphere, the maintenance time maintenance situation this method takes long, labor intensity of maintenance workers, after removal of refractory brick layer internal flange ring is not easy to recover, so the main consideration, the key point is how to move without the hot blast valve under the flange ring the replacement, and can obtain good effect in use, after the discussion presents a real hot air valve replacement flange hydrosphere overhaul scheme research.?????? ???? ???? ???? ????????? ????? ??? ??????? ??? |
