Simply put, absolute spread in a rolling mill is the difference in the width of the stock we put in and the width of the finished piece. For instance, if a bar goes in and is rolled to reduce its thickness and it is 4 inches wide when it goes in and is 10 inches wide when it comes out, the absolute spread of the rolling mill in this operation is 6 inches. (The maximum output width, 10 inches, minus the input width, 4 inches, equals the absolute spread, 6 inches.)

What is a rolling mill?
In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes
How pass line is calculated in hot rolling mill?
Rolling schedule is the time sequence of passes of rolled piece through the mill respecting many constrains and limitations such as:* Limit separating force* Limit rolling torque* Bite angle* Flatness limits* Metallurgical limits* Specific limits(length of delay table, etc.)If all constrains are fulfilled and rolling schedule gives maximum productivity (minimum production time) and the desired product and its specifications are obtained, we can speak about optimum rolling schedule.

What is the advantage of tandem rolling?
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types.Advantages:Highest production rates,Optimized yield,Reduced roll consumption,Flexible productionTight tolerances for strip thickness, shape, and high surface quality,Low costs for operation, maintenance, and minimum down times.
What is the average price range for buying a rolling mill?
The price of rolling mills can vary greatly depending on the size of the mill and the material it's made of. Generally rolling mills cost somewhere between $500 and $1000.
Where does sheet material come from?
