General Description of the Design

Nowadays, in the world, China has become the world's largest copper metal material production market, and at the same time is also the biggest consumer market. So the demand for copper and its alloy metal materials in the our country is very big, copper and its alloys can be used in electronic electrical, communications, instrumentation, machinery manufacturing and transportation and other fields. And the use of copper, especially since the modern communication and the development of semiconductor industry, electronic industry, not only to increase demand for copper belt, at the same time for copper strip quality put forward higher requirements, such as: high performance and high precision, high surface density, etc. This topic for electrical accessories products with copper belt process design but also embody the copper's widely used in electronic appliances, and mentor according to actual production application combined with research projects in their lives.

Copper uses more expansive than pure iron, is used mainly for generators, busbar, cable, switchgear, transformers and other electrical equipment and heat exchangers, piping, solar heating device thermal equipment such as flat collector. In addition, the copper is also used in motor short circuit ring, made of electromagnetic heating inductor, and high power electronic components, wire line terminal blocks, etc.Copper also apply to the furniture such as door, window, armrest and decorations. According to the requirements of this specification for the products, such as melting, rolling system and force parameters on the strength of design calculations and equipment capacity and checking to complete the task required by the process, and at the delivery status of products required. So finally according to the previous design of products and product use and performance to generate products of copper. Because it is electrical accessories with copper strip, so the choice of T2 copper, Chinese standard GB/T 2059-2008. The raw material size is 170×630×5100mm.The finished product size is 0.3×200×3000mm.

The main components in T2 copper 99.99% of copper, the rest of impurities in the ore. So the T2 copper belt of the whole design of the production process is:

1. According to the ratio of raw material for smelting and casting. After by melting furnace heating, melting copper water passes through the holding furnace heat preservation and plant composition analysis after the adjustment of the following is the copper water poured into the horizontal continuous casting machine casting, finally cast ingot billet required for subsequent production.

2. Hot rolling rolls and milling surface. When after melting and casting of billet after stepping furnace out by the table into the reversible hot mill, after 9 times of hot rolling mill rolling, the original thickness is 170 mm thickness of slab ingot will be reach 15 mm, after that and then to roll and through the double milling, this step is for the sake of milling to billet oxidation layer on the surface of the up and down, double-sided milling and milling to the thickness of 2.5 mm.

3. Cold rolling and middle annealing. After hot rolling and double-sided milling, will conduct is cold rolled. And rolling, the cold rolling belt type "method is the copper billet into cold mill rolling after uncoiling, according to the procedures set by the pressure system in the before rolling and after rolling and coiling. Because of work hardening, so the bell type annealing furnace for intermediate annealing to copper billet recrystallization to eliminate the strain hardening. After all throughout the cold rolling mill process, to achieve the copper billet thickness of the previous design, which is 0.3 mm.
