Hot rolling is the most commonly used and wellknown technology for producing carbon steel and smaller stainess steel profiles. Depending on the alloy, desired shape, mechanical properties, and surface aspect, hot rolling can be the most suitable and cost effective production method. Cost Savings and Sizes of Hot Rolled Profiles
Cold Strip Mill Cold rolled strip steel and sheet steel generally have a thickness of 3 mm and a width of 100 2000 mm; All of them take hot rolled strip steel or steel plate as raw materials and are rolled into products by cold rolling mill at normal temperature.
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.
Two separate rolling mills are employed to process the raw steel blooms into rebars and highquality steel bars to be used in the automotive industry or in machine construction. To this end, the blooms are once again heated up in a pushertype or in a walkingbeam furnace respectively prior to hotrolling into the size requested by the customer.
Section and billet mills Hot rolling. SMS group ... Extremely versatile, heavy section mills produce not only beams, but also channels, angles, shipbuilding sections, special sections, and sheet piles. Depending on your product range, we design your mill for the size spectrum you want. Typically, these mills produce web heights measuring up to ...
Jul 13, 2015· The composition of a normal universal beam mill to roll universal beams consists of a high pressure water descaler to remove scale from the heated blooms, a two high reversing break down rolling mill with multi groove rolls along with manipulators on both side of the rolling stand, a tongue saw to cut the head end of the material, a universal ...
Sep 11, 2014· Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel''s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
This example shows how to design a MIMO LQG regulator to control the horizontal and vertical thickness of a steel beam in a hot steel rolling mill. Rolling Stand Model Figures 1 and 2 depict the process of shaping a beam of hot steel by compressing it with rolling cylinders.
Bar rolling mill cooling bed almost all walking beam cooling bed. With the increase of annual output requirements of rolling mills, the structure of steptype walking beam cooling beds is gradually improved to adapt to higher annual output and higher rolling speed.
This information will both advance control and monitoring of plant performance, revolutionizing long rolling mill plants worldwide and optimizing the entire value chain, along with improved and more flexible production, utilizing the latest control and drive technology. Digitalization of Long Rolling Control System – Smart Sensors
send to the roughing train of the mill for rolling process. b) Roller table: To discharge the hot blooms/billets/slabs to rolling mill for rolling operation. III. Mill Section: To roll the hot blooms / billets / slabs etc. into desired shape by passing it between set of revolving rolls. The rolls may be plain or grooved rolls depending on product.
The Hot Rolling Mill Cooling Bed is composed of a mechanical transmission system, water cooling system, the working table of the cooling bed, fixed support, etc. The main cooling beds are the pullout cooling bed, walking beam cooling bed, pullclaw cooling bed, transport chain cooling bed, rolling disc cooling bed and so on.
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.
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.
structural sections (beam, channel, joist, rails, etc). The initial breakdown of ingots into blooms and billets is done by hotrolling. The process involves plastically deforming a metal work piece by passing it between rolls. Rolling is the most widely used method of forming / shaping metals, which provides
Nov 29, 2017· The 3roll precision sizing mill will be used to roll purely SBQ grades in the diameter range from 25 to 83 millimeters. Supplemented by the PSM® (Precision Sizing Mill), Steel can now ...
A cooling bed is part of a rolling mill, at the end of the rolling mill that supports and permits the hot rolled products from the hot mill to cool hot rolled and cast steel products. A walking beam cooling bed is the most common type of cooling bed. What one wants to happen is for all the temperature of the bar to all cool at the same time.
