The initial stage in the subject, first in the Aluminum Copper Co., Ltd. was for a period of two weeks of production practice, content and related knowledge of the subject, further recognition and understanding beyond books, and determine the research direction and ideas. Copper nickel zinc alloy has excellent resistance corrosion, comprehensive mechanical properties and hot and cold forming of, easy cutting, made of wire, bar, and panel for instruments, meters, medical equipment, daily necessities and communication in the field of precision parts manufacturing. According to the determined product scheme and its performance and usage, the use of copper nickel zinc alloy were grade BZn15-20, size of raw materials for 15X430X83205mm, finished size M 0.5X300m, delivery status for M state; grade BZn18-18, size of raw materials for 15X430X83205mm, finished size 1.0X200mm, delivery state to a state of y.
BZn15-20 proportioning ratio: Cu63%; Ni+Co15%; Zn allowance 22%.
BZn18-18 proportioning ratio: Cu65%; Ni+Co18%; Zn allowance 17%.
The ratio of raw materials and smelting, casting 1. By heating smelting furnace of copper in water after holding furnace insulation and the analysis of the composition adjustment, into a horizontal type continuous casting machine casting, cast rolled blank.
2 cold rolling, intermediate annealing. Take type rolling method, namely decoiled copper billet into mill rolling, to the rules set by the system pressure after coiling, intermediate annealing improve copper billet plastic properties by means of bell type annealing furnace. After the whole cold rolling, the thickness of the copper billet can reach the requirement of the size of the finished product, that is, 0.5mm and 1.0mm.
3 shear straightening, product quality inspection. To confirm that the product meets the design requirements, it can be packed in storage, waiting for delivery.
Throughout the design of the product technical requirements can be summed up in one sentence: the size of the exact shape of the plate, the surface finish high performance.
(2) in the selection of design used equipment, mainly with reference to the Aluminum Copper Co., Ltd. is the production of the equipment, main production equipment and auxiliary equipment: 4.0 tons holding furnace, horizontal continuous casting machine, milling machine, volume take machine, two / four roller cold rolling mill, a bell type back fire, transverse shearing machine, thick longitudinal shearing machine.
The rolling force can be calculated by the preparation of the appropriate VB language, and the use of CAD to draw the workshop floor plan, roll, make full use of the computer in the actual production of the advantages and applications. And check the frame, motor and auxiliary equipment capacity, to calculate the main economic indicators of the workshop, to ensure that the entire design can be used in the actual production.
This design mainly describes the production technology requirements of topic origin and the BZn15-20, BZn18-18 copper, making the smelting system and a reasonable product process is based on the Aluminum Copper Co., Ltd. existing production equipment and pipeline design, and the product production, production of formulation, force calculation parameters, equipment strength check, check the motor, auxiliary equipment capacity calculation and the workshop of major economic indicators of calculation and CAD drawing of workshop layout figure, roll, roll force and bending moment and torque diagram.
