· In a sense, raw materials used in concrete are just like the food we eat: They should be of good quality, they must be stored and handled properly, and they must not be contaminated. The old adage "You are what you eat" comes to mind, because the quality of raw materials going into a concrete mix has a direct effect on how the final product will turn out – in both fresh and hardened states.
· Further selected raw materials is required for the production of specific quality steel. For better and efficient operation of melting in induction furnace, raw material charge must fulfill the following criteria. It must be as dense as possible. Compaction of scrap is important for ensuring uniform and rapid heating as well as for energy saving.

Why the steel industry is important. Production the EU is the second largest producer of steel in the world after output is over 177 million tonnes of steel a year, accounting for 11% of global output. Link to other sectors – steelmaking is closely linked to many downstream industries such as automotive, construction, electronics, and mechanical and electrical engineering.
When margins are high and mills are profiting from each tonne they produce, they prefer to use highpurity ores to maximize their blast furnace yield. Intergrade price spreads tend to expand during these times, and highgrade indices such as the MBIOI65BZ and Metal Bulletin 66% Fe Concentrate Index (MBIOICO) usually extend their premiums to the MBIOI62 and Metal Bulletin 58% Fe Iron Ore ...

nowadays. But these process are selected with due consideration given to the properties of raw materials, cost of fuel, condition of loion and others. For the wet process, plant construction cost is rather low and high quality products are manufactured easily. On the other hand, dry process consumes less energy and its running cost is lower.
· There can be negative effects of using lowquality raw materials during production, such as higher GHG emissions, that could cause environmental disruption and higher energy consumption. While using a blast furnace (BF) and lowgrade materials to produce steel, more energy is needed than when using highquality materials and the waste nonmetallic components are converted into .
Working principle of pulp digester. Before cooking, all raw materials must keep moisture content below 15 percent, silicon less than 3 percent, ash about 23 percent and cellulose about 5055 percent. First, cut the raw material into about 25 by 30mm slices and feed them into the cooker through the conveyor belt.
