Hot rolling is a process in a steel plant in which the semifinished slab is reheated to a predetermined temperature and the hot slab is rolled to make the specified hot strip in a coiled form The role of a hot strip mill HSM is to produce strips from semifinished steel slabs.
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.
Youll appreciate X Roll 174 hot strip mills from SMS group as all round plants for high quality hot strip They are designed to produce flat steel from thin strip with a minimum final gauge of 1 2 millimeters to high strength pipe steels up to 25 4 millimeters thick including stainless steel grades.
The second volume of Hot Strip Mill Operations is aimed at one primary objective roll cooling is for shape and has little to do with roll wear The demands of operators roll manufacturers and mill builders for low roll wear prevention of roll breakage good shape minimizing fire cracking and surface appearance are all inclusive in roll.
Rolling is a metal forming process in which metal stock is passed through a pair of rolls There are two types of rolling process flat and profile rolling In flat rolling the final shape of the product is either classed as sheet also called quotstripquot thickness less than 3 mm or plate thickness more than 3 mm In.
Hot Sheet and Plate Rolling Fundamentals Practical Training Seminar About the Program This seminar provides a comprehensive overview of hot rolling steel strip and plate The course covers fundamentals metallurgical and quality requirements equipment rolling theory control rolls temperature control measurement safety and new.
System was installed in the seven stand hot strip mill of voestalpine180s steel plant in Linz Austria in 1997 It is able to predict the mechanical properties as well as the thickness and composition of the scale layer of the hot rolled strip immediately after cooling and downcoiling A simulation of all process steps such as austenitization.
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 amp Thin Slab Caster Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill Long Products.
PROCESS AK Steel is committed to producing top quality products by utilizing modern well maintained equipment This begins with quality slabs produced by continuous casting producing a uniform chemistry for Hot Rolled Steel The hot strip mill is designed to produce consistent surface quality uniform mechanical properties and consistent.
Measures strip and sheet temperature to efficiently set up the rolling mill to match the steels temperature These sensors also detect the presence of hot metal to accurately time the roll stand operation for maximum efficiency LumaSense IS 320 Pyrometer 150C TO 1200C and LumaSense IGA 32023 200C TO 1800C were utilized.
The hot strip mill shown in the drawings is particularly for the production of thin and broad metal strip in the thickness range lt 1 5 mm and the breadth range gt 600 mm from a hot strip 1 notably steel strip made by a hot rolling process.
Hot strip mill Around a third of the products we send out to our customers are hot rolled In the hot strip mill Ghent slabs coming from the continuous caster are rolled out to steel plates with a thickness of around 1 25 to 13mm How does this work First the slabs coming from the continuous caster are pre sorted in the slab yard.

In order to understand and reduce the problems of camber in the hot strip mill it is important to be able to measure it accurately However up until now a suitable instrument was not available on the market Sollac Dunkirk pilot plant together with IRSID and EES decided to develop and test a trial online system in the roughing mill with financial support from ECSC By means of a.
Cutting line of the hot strip mill with Autoset couplings The 155 m long cutting line have a strip width of 2250 mm and run with a strip speed of 40mmin The Autoset slip and release coupling offers two function Primary function is to make micro slippages during the leveling process to reduce high torque peaks Secondary.
Beam furnace Secondary scale is formed during the rolling process in the roughing mill area and tertiary scale within the finishing mill and coiling train SCALE REMOVAL FROM STRIP SURFACE BY HIGH PRESSURE WATER JET High pressure water jet is normally used to remove the scale from hot strip.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill work roll temperatures normally fall in the range of 55oC 70oC with strip recoil temperatures and inter stand strip temperature rarely exceeding 160 oC depending on product.
Analysis of a Continuous Heating Process Hot Slab Charging Effects of Skid System on Heating 15 Heat Transfer During the Rolling Process Workpiece Temperature Change in Hot Strip Mill Temperature Loss due to Radiation Temperature Loss due to Convection Temperature Loss due to Water Cooling Temperature Loss due to Conduction to Work Rolls.
Continuous casting and rolling steel strip was a revolution in steel industry at the end of the last century Some thin gauges that conventionally have to be produced by cold rolling can be obtained now from hot rolling with the new CSP or ISP process which can roll 1 2 mm now and maybe 0 7 0 8 mm in the future.
Chatter is a common term for the intense undesirable mill vibrations occurring in both hot and cold rolling Its cost could be very high due to the reduced strip quality and equipment damage.
The first Hot Strip Mill at Vijayanagar was commissioned in 1997 Since then it has grown exponentially and now has an installed capacity to produce 10 MTPA of steel Located 380 kms from Bangalore in Toranagallu North Karnataka a part of the Bellary Hospet iron ore belt it is a fully integrated steel plant well connected with both Goa and.

The Hot Strip Mill Model HSMM is an invaluable tool to cost effectively assist in determining the optimum processing conditions to achieve the desired product properties This model runs in an offline mode thereby saving many tons of wasted product that might be scrapped in trying to identify the proper mill.
During the hot strip process route slabs are heated in two walking beam furnaces and subsequently reduced in the roughing mill to a transfer bar of 27 mm which is coiled in a coil box This coiled transfer bar is rolled in the finishing train to produce a hot rolled coil in the dimensions required by the customer.
