A reduction gear box is used to reduce an input speed to a slower output speed. It is a wheel work consisting of a connected set of rotating gears by which power is transmitted or motion or torque is changed. We can manufacture and supply single stage, double stage or multistage gear boxes having Single and Multiple outputs as required. From Low Speed to High Speed, Technicalities of our Reduction Gear Boxes are:

Normal Input Load Range

• From 50H.P.up to 8000H.P.Drives

Gear Type

• Spur, Single and Double Helical Gears, Bevel Gears, Worm Gear Box up to 3500mm dia

The gear boxes (Reducers/Increasers) and Pinion Stands designing and manufacturing is also the frame of our technical and engineering expertise with modern features as per industrial standards and requirements. The gear boxes are highly efficient due to case-hardened steels of high strength bearings of ample dimensions, steel fabricated body for smooth running and low noise.

We manufacture and supply complete mill stands for the rolling of Strip Wire rods/TMT/Light Section/Medium Section and Heavy Section steel, ferrous and non ferrous metals. Technicalities of our Mill Stands are:

Type

• 3 Hi & 2 Hi Horizontal Stands 2 Hi Vertical Stands, Universal Stands and Housing less Stands.

Size

• 6"-30" i.e. from 150 mm PCD to 750 mm PCD Mill

These Bearing Chokes are of rolling mill duty and blend in between window of rolling mills stand. These bearing chokes are suitable for antifriction roller bearings. The bearing chokes are of EN-8 fully machines accurately with bearing sizes. The bearing chokes are complete with side cover, sleeves/lumbering and chick nut.

Universal couplings are inserted at the journal of the rolls, to couple the mill stands. These are basically for the power transmission from one stand to another. Manufactured out of forged steel, they are highly applicable at mill stands with repeaters or high loads. They are designed and manufactured as per the load of the application.

Spindles are used as a device for power transmission and are placed between Couplings. Spindles are manufactured out of forged steel, basically EN-8 or EN-9 and are properly machined as per the design and requirement.
Our manufacturing range of spindles includes: Palm/Key Groove Type, Star Groove Type

A Charging Pusher is an electro-mechanical or hydraulic device which is used for feeding or charging of raw material (like ingots, billets etc) into the reheating furnace. Various components which are used in the manufacture of a charging pusher are: heavy steel slab frame, pushing screw with pushing slab, multi stage type reduction gear box or a hydraulic power pack with alloy steel shafts in case of a hydraulic pusher. Depending on the raw material to be fed i.e. scrap roll, ingots/billets or heavy blooms and their sizes, the mechanical or hydraulic type pusher is designed and supplied.

The basic function of pinch rolls is to push the material in a particular direction. It does not cause any kind of physical change in the material and is usually used to move the material over a distance. It is installed at various places in a rolling mill such as between the roughing mill and the intermediate mill, before and after the TMT Quenching Box to maintain the speed and tension of bars. It is driven through an AC/DC motor and consists of 2 Hi Gear Boxes, Solid Rolls with Carbon Shaft.

Discharging Ejector is an electro-mechanical device which is used to expel the hot material from the re-heating furnace to the rolling mill. It has a mill housing type structure with a movable frame and can do both front and side travel for discharging of hot material (like ingots , billets)from re-heating furnace .It comes complete with heavy stands, rollers, cooling system, wheels for cross travel, gear box, pushing arrangements etc. It uses a square billet of approx.6 meters (or more) length as the device to push the hot material out of the re-heating furnace. It is manufactured depending on the size and capacity of the re-heating furnace.

Foundation Lines are used for the foundation of mill stand, gear boxes etc. They are made of cast Iron. Cast Iron is used because it can absorb the vibrations. It is fully machined and leveled in order to provide proper support and base to the machines standing on it. The basic reason for installing the foundation lines/base plates is to strengthen the bottom base of the machine and to distribute the load uniformly.

A flywheel is a heavy metal wheel attached to a drive shaft, having most of its weight concentrated at the circumference. The main function of a flywheel is to reduce speed fluctuation by storing extra energy during part load as kinetic energy and the same is released during overloading by slowly increasing the speed of a flywheel, a small motor can store up energy which enable the motor to perform a function for which it is ordinarily too small.

A Gear Coupling is used for transmitting torque and power between two shafts. It is normally used for the coupling of motor to fly-wheel, fly-wheel to gear box etc. It is individually designed and manufactured to specific requirements. It is a triple crowned double engagement type with Hexagonal and Allen Bolt, forced greased having reamed flange hole. We provide half and full gear couplings of 101 and above sized as per the customer's requirements.

A Pulley is a power transmission cum speed controller device which can be used at various places depending on the application and size. In Rolling Mills, it is used from motor to flywheel and flywheel to gear box so as to control speed, input speed as per the application. It is duly machined and balanced and comes in all groove sizes and bores. The material mostly used to manufacture the pulley is graded cast Iron. We make pulleys from 150mm to 3500mm dia. It comes complete with shaft, bearings, plummer blocks, base plates and foundation bolts etc. It is designed and manufactured as per the application.

The Rolls for re-rolling mills are manufactured by forging and centrifugal spin casting process. The rolls are manufactured in alloy steel grades such as EN-9, EN-42, and unalloyed grades like spheroidal cast iron and chilled cast rolls.

Vertical Stands are also known as edger in Rolling Mills. They act a independent stands and are used to maintain the size of the material. They come with a complete independent set of rolls, reduction gear box and independent fly wheel.

The machine function is to straighten all the deformed products i.e. (angles, channels, flats, I-beams, squares etc.) based on the well proven rotary straightening process. The roller of the machine is designed in such a way that it will remain in contact of the product, (width and thickness), during the straightening process.
Robust construction of machine gives high level resistance and stability. The rollers of the machine are arranged in two ways i.e. upper rollers and bottom rollers. By adjusting the horizontal and vertical movement of the upper rollers, it is very easy to use the machine for different sizes of the section.

ASM Manufacture the following types of Gear boxes.

• Single/ Multi Stage reduction Gear Boxes
• 2 Hi & 3 Hi Pinion Stands
• Single input single Output Gear Boxes.
• Single iNput multi Output Gear Boxes
