steel roughing rolling mill stand

3 Finishing Lines coupled with roughing train for achieving desired reduction. 4 Continuous Stands 305mm for precision rolling or Sizing Mill. Online Oxygen Monitoring System to control the levels of oxidation. Max O2 content in reheating furnace ranges between 2 to 4, resulting in better surface finish and minimum decarb.

The roughing mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.

A rolling mill is the place where the rolling of steel in carried out. It consists of one or more rolling stands along with some auxiliary equipment where auxiliary operations associated with the rolling of steels are performed. Rolling of steel in small and medium sized rolling mills is generally carried out in crosscountry rolling mills.

Steel continuous hot rolling mill group for wire rod , rebar and other sectional rolling mill Introduction Roughing is to make the earth material get preliminary compression and extension, temperature appropriate, cross section shape correctly, the qualified size, the surface is good, end rules, length is suitable for the rolled piece process requirement. is a company specialized in the

Rolling mills create a lot of force when they are being used. I really recommend mounting your rolling mill to a heavy bench, mounted to the wall, or bolted to a sturdy steel stand and bolted to the floor. Many small jewelers benches just arent heavy enough to mount a rolling mill to.

The workhorse roughing mill has 135 wide rolls for rolling broadside as the first roughing mill is commonly called to make a slab wider. A 5,000 hp motor drives 42diameter workrolls through 281 gears to reduce the slabs thickness by as much as 2. The last four roughing mills each incorporate edgers for width control

The mill rolls take an initial thickness reduction in preparation for the finishing stands, Steel temperature must be monitored to meet parameters and prevent roll damage. Solutions SPOT R100 or LSPHD 10.

Rolling The important parameters for rolling in the roughing, intermediate, and finishing group of stands in the rolling mill are temperature, percentage of reduction in area, interpass time

Mill Stand can be made available by us from 210 mm 8inch size up to 600 mm 24inch size options. Here, we make use of only steel casting C.I ultra sonically tested material in grades as per the specified requirements so as to provide for optimum functional support in the offered mill stand range.

Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel Ibeams, angle stock, channel stock, bar stock, and rails. Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products.

Mill for production of flats and serrated flats. The billet is rolled through the rolling mill consisting of 3 HI400cc Roughing Mill, 4 Stands Intermediate Mill and 6 Stands Finishing Mill. The Intermediate and Finishing stands are of continuous type having PLC Automation.

The steel roughing rolling mill stands are used to reduce the thickness of the steel while at the same time extending the overall length Roughing Rolling Mill Stand Function Side loop is before finishing mill group, function is achieving Tensionfree rolling between prefinishing mill and finishing t

AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.

The steel roughing rolling mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Steel Roughing rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.

Consider the hot rolling of a lowcarbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30 using work rolls of 800 mm diameter, rotating at 50 rpm. The coefficient of friction is taken to be 0.2.

Shree Gautam Rolls, 9001 2015 certified company, since 1994, as an exporter and manufacturer, we have always been concentrating on the research and development in production of steel rolling mill rolls, hot rolling mill rolls, chilled rolls, spheroidal graphite iron rolls, alloy steel adamite rolls, forged rolls.

The long product rolling mills can also be designed as a single strand mill or two strands mill. In two strands mills, rolling in roughing group of stands takes place in two strands and in such mills there are two sets of intermediate and finishing stands where the rolling takes place in single strand.

McDonald Steels 14 production line is an eleven stand crosscountry bar mill. After the hot steel bar exits the mills roughing stands, it is never in more than one roll stand at any time. This is vital to hot rolling nonsymmetrical shapes because it allows the bar to spread into the required shape that has been contoured into the roll
