Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.

Transition effects and text preset animations The transition effects from one slide to another and the text preset animations (which determine how the text will arrive on each slide) have been set at random for the demonstration. This is so that you get an idea of the variety of transitions and animations you can use in PowerPoint.
Jan 14, 2013· CONTINOUS CASTING AND HOT ROLLING• Metal is melted, cast and hot rolled continuously through a series of rolling mills within the same process. 18. THREAD• Rolled threads are produced in a single pass at speeds far in excess of those used to cut threads.• Dies are pressed against the surface of cylindrical blank.
Reheating Furnace is the heart of any hot rolling mill where in the charge is heated to rolling charge could be in the form of billets, blooms, slabs or type of furnace could be pusher, walking hearth or walking beam – either top fired or top and bottom fuel used could be either oil or gas.

strongly depends on hot rolling parameters such as strain, strainrate, temperature,groovedesignandrollingsequence. It influences the metal deformation behaviour within the pass and mill load requirement apart from roll wear. The metal flow behaviour in a hot rolling process is a complex phenomenon, which is complicated due to tensorial stress

The pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is usually located on the ground or main work floor level. The hot, extruded mash .
Continuous mills are used in the hot rolling of billets, bands, section metal, wire, and tubes and in the cold rolling of sheets, sheet metal, and strips. Rolling speeds vary greatly and depend mainly on the required output of the rolling mill, the range of rolled products, and the technological process.
You can set up your slide shows to include a little preview presentation that will help prime your audience for the main event. Susan Harkins shows this simple but highly effective technique.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Hot rolled product, and below is cold rolled product. In case of hot rolled, the temperature of the product is above recrystallized temperature and the product after hot rolling is relatively large and thick. And since rolling is carried out relatively high temperature, deformation of this product is rather easy.
When the holes are to drill more than one plane of the work piece, the jig has to be provided with equalant number of bush plates. For positioning jig on the machine table feet have to be provided opposite each drilling bush plate.
four processes: hot metal pretreatment, converter process, secondary refining process, and continuous casting to remove excess carbons and impurities for chemical adjustment in order to produce an intermediate material known as "slab". From ColdRolling to Annealing. Pickled coils are rolled to the specified thickness . by cold rolling.
