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.
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.
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.
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.
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
Aug 28, 2019· The rolling mill will comprise a combined roughing and heavy plate line on which either transfer bars or plates can be produced. The roughing and heavy plate line will handle ingots with thicknesses between 400 and 830 millimeters, widths from 1,050 to 2,650 millimeters and lengths from 2,000 to 8,400 millimeters.
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 ...
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.
June 24, 2019 September 26, 2019 Steel Mill Modelers Supply BOF Slag Pots Modeled one of the many prototypes available. Trunnions are prototype width and size for use with J hooks and match our charging ladle and scrap box, along with many of the modeling industry manufacturers.
Walking beam reheating furnace is widely used in mechanized hearth furnace, and is the main type of furnace to replace pusher furnace.. The bottom of the walking beam reheating furnace is basically composed of movable part and fixed part. According to its different structure, there are walking beam type, walking bottom type, walking beam type and bottom combined heating furnace.
This stage sees the steel slab rolled to form an intermediate product. Accurate temperature monitoring is essential for product quality and to protect the .
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.
Contactfree measurement of the temperature in steel and rolling mills and in metal working. The monitoring of temperature with contactfree yet precise measurement of the object is gaining tremendous importance in the steel and iron industry.
Wide Flange Beam Wide Flange Beam Gerdau hotrolled wide flange (WF) beams are used in structural steel construction, in applications from industrial facilities and health care to commercial buildings and multifamily residential projects.

Rolls for H beam Steel Mills. We offer rolls for mills that produce H beams steel which are widely used in buildings, bridges, ships, and quay walls ...
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 ...
Apr 13, 2013· Reheating furnaces are used in hot rolling mills to heat the steel stock (Billets, blooms or slabs) to the rolling temperatures of around 1200 deg C which is suitable for plastic deformation of steel and hence for rolling in the mill. The heating process in a reheating furnace is a continuous process where the steel stock is charged at the ...
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.
According to the type of rolling mill: (1) Flat roll. That is, the roll body of plate and strip mill is cylindrical. Generally, the roll of hot rolling plate rolling mill is made into micro concave shape, which can obtain better shape when heated; the roll of cold rolling plate rolling mill is made of micro convex shape, and the roll will bend during rolling to obtain good shape.
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
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.
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.
