Damage Of The Sludge
The steel making process makes a lot of sludge (about 8 to 12% of the steel production), such as the blast furnace sludge, gas sludge, steel rolling sludge, steel rolling iron oxide scale, sintering dust, steel pipe graphite sludge, etc. Get rid of these sludge will help the plant to reduce the cost of the product and prevent pollution. The sludge needs a lot of files to be placed and will sink into the soil with the rain, change the content of the soil, and even with heavy metal.
The Ingredient Of The Sludge
The main ingredient of the sludge is usually iron oxide and calcium oxide, it also contains oxides such as silica, magnesia, and alumina, which further may contain zinc oxide and lead oxide, depending on the type of scrap used. These ingredients will fluctuate with changes in the number of raw materials, molten iron, and flux added during smelting. At the same time, they will change with the oxygen supply system, furnace operation conditions, dust removal, and sewage treatment systems.
Make Value From The Sludge
The iron dust sludge usually contains CaO and FeO, the sludge briquette can be used as the slagging agent, flux in the steel making process. These sludge, which is full of tiny particles, also helps to make the briquette quality better when mixed with other materials.
The Benefit Of Using Blast Furnace Sludge Briquette
1. Advanced the slag removal time, reduce the smelting time.
2. Replace fluorite briquette, make protection for the environment, and improve the service life of the furnace.
3. Reduce the CaO briquette cost.
4. Early dephosphorization and poly phosphorus dephosphorization due to the fast slag and more content of FeO and CaO.
5. Reduce iron and steel consumption.
6. Shorten the oxygen supply time, reduce oxygen consumption.Directly briquette them is a good choice for recycling. The process is easy and with low investment.
Sludge Briquette Plant With Charcoal Briquette Machine
Set up a sludge charcoal briquette plant, the most important thing we need to pay attention is the moisture. Normally, the original sludge has to be pre-treated to drive off the excess moisture to meet the requirement of briquette making.
The whole process:
Raw sludge → Crush → Dry → Briquette → Carbonization → Conservation
