The production of steel in an EAF is a batch process. Cycles, or heats, range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages
Cold-rolled steel sheets are produced by cold rolling from hot-rolled coil, the typical manufacturing processes are described as Fig1. Pickling and Cold CSVC produces its cold rolled products by the combination line of PLTCM (abbreviated from Pickling and Tandem Cold-rolling Mill), and CAL (abbreviated from Continuous Annealing Line) respectively.
Please note This diagram aims to show steelmaking today. This diagram does not feature the new input materials and processes that are being developed and will dramatically change how we make steel in the next 30 years as we transition to the low carbon economy.

Cold rolling causes steel to become hard and brittle. To obtain the desired microstructure and improve mechanical properties, the cold rolled strip is annealed at the suitable temperatures. TCRSS employs 100% Hydrogen atmosphere annealing facilities. Coils can achieve homogeneous qualities and higher production rate due to higher heat transfer.
steel sections are cold-formed, i.e. their manufacturing process involves forming steel sections in a cold state (i.e. without application of heat) from steel sheets of uniform thickness. These are given the generic title Cold Formed Steel Sections. Sometimes they are also called Light Gauge Steel Sections or Cold Rolled Steel Sections. The
COLD ROLLING MILLS Continuous Pickling Line (CPL) HCL Continuous Pickling Line with a capacity of 1.4 Mtpa uses proven and reliable technology to process hot rolled carbon steel as per the technical specifications.

Apr 17, 2019 1 The steel strip is scratched by a hard object during cold rolling, usually in the form of strips, and parallel to the rolling direction. If the degree is serious, the groove can be felt by hand The steel strip is scratched due to the inclusion of hard objects in the wool felt of the annealing furnace.

Steel bars are available as normal hot rolled, precision hot rolled and cold nished. Normal hot-rolled bar is made to standard AISI toler-ances and is the least costly form of steel for making slugs. It is also likely to have deeper surface seams and greater depth of
Nov 09, 2013 Continuous annealing of cold rolled steel was first introduced by the Armco steel corporation in the year 1936 as a process step in the production of hot dip galvanized steel. Since then several improvements have been made in the process which allows several types of steels to be processed by this method.

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% 34.This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong 111 recrystallization texture are the annealing temperature and the time of holding 35.
