Thanks to integrated process models today''s demands for flexible and economic production of steel plate can only be met by electrical and automation solutions based on technological process modeling, highperformance control systems, and a comprehensive understanding of hot rolling technology.
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.

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
This overview is meant as an introduction and a summary. Each piece of HTST equipment will be discussed in further detail later. Please refer to the two diagrams below when reading this section hopefully the flow of milk through the HTST pasteurized will then make sense.
SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
hot rolling mill process Rolling (metalworking) Wikipedia OverviewIron and steelOther metalsModern rollingHot and cold rollingProcesses In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.

The hot metal is decarburized to the required carbon content in the BOF. The main reaction in this process is the oxidization of the carbon in the hot metal by both pure oxygen gas (O 2) and iron oxide (Fe 2 O 3). The residual oxygen, after contributing to this decarburization reaction, remains in .

Schematic representation of a continuous cooling transformation diagram in CMn steel, cooling patterns in the present ...
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.

The hot metal is converted into steel through a steelmaking process called the LD process. Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill. Long Products:

FLOWCHART 1. Convert the following flow chart into a paragraph of about 150 words. The process of making cement is described in this flow chart. The two raw materials used in theprocess are limestone and clay. Limestone is crushed, sized, dried and stored in storage silos. In the same way, Clay is washed, crushed, and dried in
Thus roll bending is a controllable parameter to modify the roll gap and hence the crown and flatness of the strip rolled in the finishing mill of the hot strip mill. Conclusions. Roll stack deflection is an important issue in the determination of profile and flatness of a strip rolled in hot strip mill.

The shells form one continuous sheet when they are brought together at the roll nip or kissing point. This steel strip is guided through pinch rolls and a hot rolling stand, where it is reduced to the desired dimensions, typically between and mm.
