UNIVERSAL GEAR INDUSTRIES & ENGINEERING WORKS

Magadi Road, Bangalore, Karnataka

Hot rolling mill for Long products, UGI Engineering has been manufacturing most modern Light, Medium & Large Section Mills of ferrous & non-ferrous Metals to minimize the operational costs, increase productivity and fuel & power efficiency and for reduction in environment pollution.

Mill Arrangement & Layout

UGI make full arrangement drawings of the Section Mill to meet customers production requirement. The mill composition is made such that production programme may be achieved with the minimum labor & with less cost of production. UGI make the plant layout to file the customers land profile. All necessary auxiliaries are also specified by UGI.

UGI Mill Stand

UGI Mill stand has Compact and simple design to ensure quick roll change, easy maintenance and to avoid major down time. Heavy duty Housing will be steel fabricated duly stress relieved with Single lubrication point is for all mill bearings and wear-out liner for enhance increase life of mill stand.

Mill Equipment

Section Rolling Mill equipment are of special design to allow quick roll setting & roll changing. UGI provides roll groove designs, complete drawings, rolling control charts etc.

The advantages of using Geared Coupling on all directly connected machinery is now recognized and appreciated by engineers and operating men. Gear couplings are intended to compensate for the usual and unavoidable errors in alignment and should allow free lateral flowto the connected shafts. Even when favourable conditions permit perfect alignment to the two Shafts, there is no assurance they will remain so, the vibrations, the sinking of foundation, wear of bearings and inaccuracies in machining are all common enemies to the safe and efficient operation of connected machinery.

UGI Engineering Works Private Limited manufactures mill stand of conventional design as well as Housing less stand of Wire Rods/TMT/Light Section /Medium Section Mills.

Salient features of UGI Stand

Compact and simple design to ensure quick roll change, easy maintenance and to avoid major down time

UGI Mill Stand is stress relieved and accurately machined.

Heavy Duty and sturdy design which is suitable for overloads.

Single lubrication point for all mill bearings and wear-out liner.

Technical Specification

3 Hi & 2 Hi stand in horizontal and vertical configurations ( Universal & Housing Less Stands).

Conventional and pre-stressed Mill Stands.

Mill Size ranging for production of 8 mm to 40 mm mill at 50 Ton/hr.

Rollneck Bearing Schemes incorporating Antifriction Spherical Roller Bearing or Multi Roller Bearing or Fibre Bearing.

Material available in Steel Casting/Cast Iron/Steel Fabricated

UGI Mill Shears & Saw Machine has made from EN-8 Steel fabricated stress relived body construction with control panel, starter, Automatic Operating System & Centralize Oil Lubrication System . UGI Engineering offers a full line of hot and cold shears necessary in a bar or rod mill for a wide variety of requirements, such as head/ tail cropping , dividing, sampling or scrapping, cutting-to-length. Sawing units are available for rails, medium-large sections, large bars, and special steel grades, where sawing is preferred over shearing.

UGI Engineering cooling beds are designed using standard elements that can be combined in accordance with plant product mix requirements and production capacity. The design features cover a variety of applications : rounds from 8 to 100 mm .

UGI Engineering provides the complete Narrow Hot strip Mill equipment, components, utility, drives, electrics and automation systems to meet demand for the highest performance, product quality and operational flexibility. Since ERW Pipe & Tube mills require narrow strip in coils, UGI has specialized in designing strip mills for to meet the requirement.

The mill ensures proper thickness & edge of the Strip . The coil weight is increased to match the pipe mill requirement. As the narrow strip need be with scale through clean surfaces the control is started from the reheating process.

Furnace Optimization

UGI Engineering are using high quality of components in Furnace including refractory bricks, Burners ( as per the design of Indian Institute of Petroleum, Dehradun ) and operate at low excess air levels, give improved fuel economy and reduced scale/burning losses. This saves on steel in addition to better surface finish of the rolled components. The heating strategy has a major influence on both the quality of reheated pieces and on the amount of fuel used for reheating.

Mill Stand

All mill stands are built heavy to with stand high rolling load. Roll necks are with antifriction bearings. Close control set up of screw down & axial shift of rolls are provided to prevent roll skewing during rolling.

Finishing Mills are 4-High design to give 8 gage accuracy. Edging stands are provided for edge control.

Cooling & Finishing Equipment

Narrow strips are coiled are edge with controls to keep the edges in time . Vibratory slat conveyers is with controlled speed to feed the strip coiler.

Coil carrying Conveyors

Coil carry conveyors are designed with optimum space utilization and to prevent scratches on strip surface.

Coil Binding machine

Coil Binding machine is automatic to strip the coil & put tags.

UGI has the expertise in manufacturing high quality PINION GEAR BOXES specially suitable for Hot Steel Rolling Mills. Input shaft is of right quality Forged Alloy Steel (EN-24) ultrasonically tested. Bearing Journal properly ground . Gear Wheel is also made out of forged alloy steel (EN-19) ultrasonically tested . Gear Teeth generated on Hobbing machines . Housing is fabricated dully stress relieved and properly machined with boring operation done on Horizontal Boring machines. We use SKF/FAG/NTN make bearings . Transparent window provided on top to observe oil splashing for Teeth Lubrication of Gears. Air breather is also provided for purpose equalisation. Oil seals of very good quality are also provided at input & output ends of shafts to prevent leakages of oil, which is a normal phenomenon in gear boxes. For these reason UGI made Pinion stand have very good in India & abroad.
