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 absolute spread in a rolling mill?
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 are the products of a rolling mill?
Products are Structural bars like Angles, Chanels, flate, round, square, TMT, tor etc.
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
Why drilling with vertical drill machine is more efficient than lathe machine?
For simple drilling, the vertical drill press is faster to use.
What is continuous rolling mill?
Continou rolling mill
Into what classifications is rolling mill machinery divided?
The U.S. government divides rolling mill machinery into four classifications: hot rolling mill machinery (except tube rolling), cold rolling mill machinery, other roll milling machinery (including tube mill machinery)
When was Chester Rolling Mill created?
Chester Rolling Mill was created in 1873.
What are the major products manufactured by the rolling mill machinery industry?
The top rolling mill machinery products by share are hot rolling mill machinery (47 percent); rolling mill machinery, not elsewhere classified, including tube mill machinery, processing lines, and machined rolls for rolling mills
When was Little Matlock Rolling Mill created?

What is apex angle and what are the advantages and disadvantages in sugar mill?
If you join the centers of the three rollers of a sugar mill in straight lines then the angle made at the top is called the apex angle of the mill.
Why rolling mills are called high roll mills?
height of the rollers in a rolling mill is normally measured from the ground level and so it is called high roll mill.
What is mean of 'hi' in cold rolling mill Specification?
meaning of Hi in cold rolling mil
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.
What is a flat wire rolling mill and its benefits?
Flat rolling is the most basic form of rolling with the starting and ending material having a rectangular cross-section. The material is fed in between two rollers, called working rolls, that rotate in opposite directions.
