To optimize steel quality the billets are brought up to the required rolling temperature within a minimum of time by inductive heating. Dwell times at only 600 °C 900 °C (1112 °F and 1652 °F), in conjunction with rapid additional heating by induction, reduce surface decarburisation and scale formation.
High casting speeds in the range of 2 m/min to 4 m/min and width of 800 mm to 1600 mm is possible. The caster is connected to rolling mill via a roller hearth reheating furnace which equalizes the slab temperature to 1120 deg C. The rolling mill can include four, five, or six finishing stands depending on product mix and required finishing gauge.

Continuous casting (CC) is a process of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine. It is the predominant process route in a modern steel plant which links steelmaking with hot rolling of steel. In the CC machine, the liquid steel is solidified into a semifinished steel ...
Site Challenges in Hot Rolling Mill. The temperature of hot rolling is around 1000°C to 1300°C. The hot rolling mill having a challenging environment for making any kind of temperature measurements like high temperature and the movement of the metal, make thermocouples and other contact temperature sensors impractical.
Direct rolling of the steel may be termed as converting the billet in to a rolled product without any intermediate reheating arrangement, thereby avoiding wastage of sensible heat of steel. In...
The continuous casting slab is directly sent to the rolling mill through the corner heating device during the conveying process without passing through the heating furnace under the conditions above A3 temperature. Continuous casting slab hot direct rolling, referred to as CCHDR, is classified into 3 categories.

Direct Rolling Technology without Heating. Direct rolling of continuous casting billet is that billet is heated by electromagnetic induction device at the opposite corner without reheating furnace, and then directly fed into the rolling mill for rolling. The technology of direct rolling without heating needs neither heating nor supplementary ...
Product Description: Billet CCM/ Billet Continuous Casting Machine. Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Continuous casting is an energysaving technique to cast the molten steel to a ...
4. Reducing production costs is an effective way for enterprises to increase efficiency; 5. Conducive to the application of endless rolling technology. The disadvantages are: due to the high hardness and brittleness of cemented carbide roll ring and high sensitivity to cracks, it is difficult to maintain, and the requirement for cooling water ...
The difference between hotrolling mills and coldrolling mills comes down to the required temperature when forming the steel. Coldrolled steel products usually have higher precision, strength, and surface finishes. Hotrolling is less expensive, provides better workability, and adds little to no internal stress as the steel cools gradually.
