Masteel's first 200,000-ton zinc dust rotary furnace dezincification project ignition oven

Maanshan Iron and Steel Group Corporation's Three Railway Corporation’s 200,000-ton/year zinc-containing dust-removing hearth furnace dezincification project has successfully implemented an ignition oven. This is an energy-saving and emission-reducing, green environmental protection project. The development prospect is very broad. It is the first time for Masteel. After the project has reached normal production capacity, the metallized pellets will reach an annual output of 133,400 tons, and zinc recovery will be 0.3488 million tons. This will be a good start for Masteel to achieve a combination of circular economy and green environmental protection economy.

Shim Washer

Washers are generally flat metal rings used to protect the surface of the connected parts from being scratched by the nuts, dispersing the pressure of the nuts on the connected parts. The gasket is a mechanical seal between two objects, which is usually used to prevent the impact of pressure, corrosion and pipeline natural thermal expansion and contraction leakage between two objects. The materials of rubber gaskets usually include Nitrile rubber, styrene butadiene rubber, hydrogenated Nitrile rubber, EPDM, silica gel, fluorine rubber, neoprene, perfluorocarbon, etc. Gaskets are usually made of sheet materials, such as pad paper, rubber, silicone rubber, metal, cork, felt, Neoprene, Nitrile rubber, glass fiber or plastic polymer.
