PRODUCTION PROCESS

BAY I: A detail overview on production process of

Bay-I is given below.

RAW MATERIAL

Brass is an alloy of Copper and Zinc. Raw materials for manufacturing brass are

Copper Cathodes, Copper Granules, Zinc Ingots and the Brass scrap.

QUALITY OF RAW MATERIAL

The raw materials that would be used for our product should be 99% and more pure.

Other wise the quality of the end product will get affected. The raw materials would

be Imported or made available from Indian markets.

In India Hindustan Copper, Birla Copper and Sterlite Industries are the major

Refineries and Smelters who Manufacture Copper Cathodes from Copper ore up to

the purity level of 99.9%.

Copper Cables are world wide replaced by fibre optic cables and these Copper Cables

contain Copper with above 99% purity. This is being sourced globally as well as from

Indian market. The scrap Copper Cable is being used in all the developed and highly

environment conscious countries for the production of Copper and Copper alloys.

Zinc Ingots are the purest form of Zinc and is available in India and all over the

world. Brass Scrap is the material, which is generated during the process in the form

of Edge and end cuttings.

Page 10: Meta Copper

MELTING & CASTING

The feed that is prepared is melted in the Electric induction furnace at 1200°C. This

furnace is of two types one is channel induction furnace and the other one is the

coreless induction furnace. The function of this 2 furnace is to melt the raw material.

SLAB RE-HEATING FURNACE

Once the raw material is melted in the induction furnace, the melted metal is

transferred to the holding furnace, where the temperature of the melted metal is

maintained for getting the uniformity. The Molten metal from the holding furnace is

transferred and poured into the vertical caster, where the mould is casted into slabs of

425x220x9000 mm length. Once these slabs are made they goes to the cold saw

section were the end bits of the slabs are cut with the help of saw and these slabs are

sent to the re-heating for further procedure. The slabs are fed in the reheating furnace,

with the help of where the slabs are preheated up to 850°C with LPG as fuel. The

control system incorporated also ensures that the slabs are heated uniformly.

HOT ROLLING MILL

The plant has been using hot rolling process to produce high quality homogenized

strips. The hot slabs from reheating furnace are sent to hot rolling mill. These slabs

are thereafter hot rolled in the form of coils.

FACE MILLING LINE

During the hot rolling process oxidization of the coils takes place, in order to remove

this, face milling is done. In this process the oxidized layer will be removed by

milling on both the surface and edges of the coils. The scrap generated will be reuse to

melting furnace.

Page 11: Meta Copper

INTERMEDIATE ROLLING

In the Intermediate rolling mill the coil is cold rolled in 4 High Rolling mills. In this

process the coil is rolled up to 1.8mm. During this process heat is generated and

emulsions are used to control the raise temperature.

CHAMBER ANNEALING FURNACE

While undergoing different process, the coil’s hardness, stress increases and to reduce

the hardness annealing is done. Annealing makes the coil softer and reduces the

hardness. In this furnace the coil is heated up-to required temperature, so that the

required hardness, stress and other physical properties of the coil are achieved. For

this purpose chamber annealing furnace and continuous Jet Floatation Annealing

Furnace are incorporated in the plant.

BAY 2: A detail overview on production process of

Bay-II is given below.

EDGE TRIMMING & PICKLING LINE

Edge trimming and pickling, of the coils is done in order to trim of the cracked edges

of the coil and also to clean the surface of the coil in order to obtain the shine of the

metal. The surfaces of the coils are cleaned with the acid with 10% conurbation.

COLD ROLLING

In this process the strip thickness is reduced as per the requirement of the customer.

Page 12: Meta Copper

DEGREASING, ANNEALING & PICKLING [DAP]

ANNEALING Furnace is Jet Floatation, where the strips float in the hot air for

scratch free finish and also to make the coils softer. DEGREASING is done to clean

the surface of the coils. These are coils are cleaned with the help of diluted acid and

Alkali degreasing. After completing annealing and degreasing, PICKLING is done to

obtain the shine of the coils. While undergoing this process the hardness of the coils is

maintained as per the requirement of the customers.

TENSION LEVELING LINE

Tension leveling is done to correct the strips flatness. During this process the excess

stress of the coils is removed and also the make the strips flat, a stretch leveler is

provided. This stretch leveler is also equipped with squeegee rolls to remove rolling

oil, dirt from the strips surface.

SLITTING & CUT TO LENGTH

In this process, the processed strip or foil is then slitted as per the customer’s

requirement on the slitting lines.

PACKING & DESPATCH SECTION

As per MCAL standard and Customer Specification packing is generally done for the finished

goods with almost care. For export either Wooden Box packs or wooden pallet packing been

done. Quality woods are being used for export as per standard. Newly introduced treated

wood pallets are also being used. In the case of country regulations fumigations also been

carried out. The standard packing criteria for DTA and Export packing detail is enclosed

herewith for ready reference. The dispatch section is mainly responsible for dispatch of

finished goods, maintenance of stock of finished goods, staffing of commercially cleared

order in container or trucks and safe custody of finished stock. Material handling & Container

staffing were to be observed for export order execution. Cross verifications of weight in

weighbridge is also to be observed for total understanding of the process.

The Environmental Care

We believe that Natural resources like fresh water, clean air and vegetation provide

sustenance and a foundation for social and economic development.

We have supported this by not only voluntarily incorporating State of the Art

Technologyfor taking care of its polluting sources but also by implementing the ISO

14001:2004EMS. We intend to Protect and conserve the quality of air, land, water and

other resources, while fostering economic development & a healthy and safe work

environment. To validate its support to resource conservation, MCAL has adopted the

practice o f rainwater harvesting to meet its water requirements

The company also practices a zero discharge policy. Effluent is treated & reused in

process/irrigation. ZnO and dross is filtered from emissions & molt respectively.

Hazardous waste like used oil, sludge, dross and ZnO are dealt by CPCB/MOEF

authorized recyclers.

MCAL has acknowledged its environmental obligations by operating over & above the

requirements of the Consent to Operate under both the Water (Prevention and Control

of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981 , as

well as the Authorization of Hazardous Wastes Management & The Registration of

Recyclers under the Hazardous Wastes (Management and Handling) Rules, 2003.

Also, as required under the Environment Protection Act 1986 an Environmental

Statement is submitted at the end of every financial year thus facilitating comprehensive

look at its industrial operations, which further facilitates understanding of material

flows and focus on areas where waste reduction and consequently savings in input costs

is possible.
