scrap copper to 8-17mm copper

I Process Specification
Put brass over the furnace by the lifting system for baking→Adjust the feeding speed according to the casting speed. Feed the brass into the melting furnace for melting (charcoal to be used for avoiding oxidization) → copper liquid flows into the transition part (charcoal is still needed to avoid oxidization) → Copper liquid flows into the holding furnace → Copper liquid flows into the crystallizer to be copper rods → copper rods enter into traction device for upward movement → Go through the output frame →copper rods go through the output frame (to separate each rod) → copper rods go through the tension frame ( to control the take-up speed) → copper rods go through the take-up machine,for coiling → Next process

3. installation: USD80 per person per day

Note: External water source, cables and wires between the equipments, air supply, power supply regulator, steel platforms etc.are not included in the price above. Equipment configuration list and one year spare parts will be listed in Annex 2.
IV Terms Of Payment
1. Thirty percent(30%) earnest money of the total price stipulated in the contract should be paid within 7 working days since the day both parties signed or stamped on the contract. he contract will take effect on the day all the earnest money is received.
2. Sixty-five percent(65%) of the total price stipulated in the contract should be paid by T/T before shipment. The shipment will be arranged when the payment is received.
3. Five percent(5%) of the total price stipulated in the contract should be paid to the seller within 7workingdays after installation and test; If the equipment can not be installed in time due to the buyer's reasons, five percent(5%) of the total price stipulated in the contract should still be paid to the seller within 5 months from the date of shipment.
4. All payments should be paid by T/T or bank draft to seller 's bank account.
V Delivery
1 Delivery time: 60 working days after the complete receipt of the deposit.
2 The buyer bears the equipment transportation and insurance costs; the seller provides unloading tools and bears the unloading costs.
3 When the equipment arrives at the buyer's site, the buyer should check the goods, sign written receiving records, and confirm the consistency between the goods and the lists of shipment.
VI Installation, Adjustment and Acceptance
1. The seller will send engineers to the buyer's site to direct the installation and test run. The buyer should prepare the installation site including, but not limited to, hoisting apparatus, labor power, tools and civil construction, etc. The buyer is responsible for the civil construction and arrange the accommodation for the seller's engineers.
2. Regard 2 copper rods coming out from the equipment as the completion of the test run; the buyer should check and accept the equipment within 3 days of the date of the completion of the test run. If the acceptance does not pass, the buyer should submit a written objection with treatment advice. Otherwise, the equipment is considered as meeting the contractual specifications and being accepted by the buyer.
VII Quality Warranty Period
1. The seller guarantees that the equipment performance complies with the requirements of the contract. The guarantee period of the mechanical parts of the equipment is 12 months, calculated from the 31st day since the BL day . (The guarantee period of the electrical parts is 6 months from the delivery date written on the contract; wearing parts are not included in the guarantee period.)
2. If the buyer does not take delivery of the goods within two months of the date of delivery stipulated in the contract, the contract guarantee period will begin on the date of delivery with the same guarantee period.Within the guarantee period of contact, defects resulting from the seller's reasons will be serviced and repaired free of charge; defects caused by the buyer will be promptly serviced by the seller, but the buyer bears all expenses.


VIII Other explanation
1. Requirement of raw material: 99.97% brass
The surface of the brass should be clean, and there should be no electrolyte or greasy substance.
There should be no "copper bean", if there is any, it must be removed . Both the surface and the edge should be smooth.
If there is no mechanical feeding device for equipment, copper materials should be cut into small pieces for easy feeding.

2. Requirements of charcoal
High-quality white charcoal (commonly known as steel charcoal, pear charcoal)
Water content: 0.5~1%
Other volatiles: ≤5%
Charcoal particle size: 30~70mm
Not allow sulfur, iron and charcoal had no calcination
Fracture should be shiny, white light, sound crisp when breaks .
Consumption:5kg/ton

3. Requirements of graphite flake
Specification: 3299 or 5099
Granularity: 32 or 50
Require natural graphite flake
Consumption: 0.5kg/ton

4. Civil and common technical requirements:
4.1Equipment area: width 9m, length 15m, height 6m:
The area does not include substation, pump house, office and maintenance workshop section.
This civil condition is for a continuous casting machine line.
Equipped with a 5-ton crane, track height is about 7.5m.
4.2 Cooling water requirement:
Cooling water arrangement: see cooling water system drawing.
This cooling water is used for crystallizer and inductor
The system also includes an emergency standby water supply, in order to prevent the event of a power outage or other accident; emergency water should be connected within a minute into the system, proposed water tower (height 7m, capacity 10m3) or UPS pump system.
In order to maintain a certain water temperature of the colling water, forced cooling must be used, usually a FRP cooling tower. Cooling tower specifications: 30m3 / hour.

5. Power requirement
The upward casting machine is for continuous production, which definitely does not allow outrage, so that standby generators or dual power supply must be considered. Standby generator capacity has to be more than 50% of the installed power.

IX Non scope of supply
1. Standby generator. The power supply for the Up casting line should not be stopped for more than 30 min; use the standby generator when it stopped. A 150kw generator is suggested for 2000tons up casting line.
2. 2000tons copper casting machine line needs 80m3 water pool, the cooling water flows into the water pool for recycle use after the sodium ion exchange filters.
3. Emergency water supply. The water supply is not allowed water stop, the height general emergency water tank and furnace height difference 7m above, it is recommended to build a tower high above the capacity of 10m3.
4. The big platform is built by the buyer, and the buyer buy the construction materials by himself. The seller will supply the construction drawing.
5. All the connecting wire outside the electrical panel should be supplied by the buyer.
6. The crane, other equipment for installation and workers.
7. The buy is in charge of all civil works (including infrastructure).
8. The buy is in charge of water pipe lines for standby water system and cooling water system.
