Equipment use
This equipment adopts continuous casting and rolling process to produce round aluminum rod (1××× series) for electrical purposes. The diameter of aluminum rod produced is Φ15mm, Φ12mm, Φ9.5mm.
2. Simple process flow
2.1 The process flow is shown as follows:
Aluminum water → insulation furnace (user's own)→ four-wheel continuous casting machine → front drawing machine → rolling shear machine → Bridge → continuous rolling mill → quadratic curve aluminum rod cooling and lubrication device → double frame continuous rod winding machine → aluminum rod.
2.2 The molten aluminum or the prepared molten aluminum is injected into the four-wheel continuous casting machine through the flow trough of the holding furnace to continuously cast into a trapezoidal ingot with an area of about 3200mm2. The waste ingot is removed by rolling shears, the qualified ingot is fed into the continuous rolling mill to roll out the rod, and the circle is formed by the double frame winding machine.
3. Equipment composition
The unit is mainly composed of four wheel casting machine (integral), front drawing machine, rolling shear machine, bridge crossing device, feeding device, rolling mill system, rolling mill lubricating oil system, rolling mill emulsion circulation system, quadratic curve roller type aluminum rod cooling and lubrication system, double station aluminum rod forming device (concentric circular type and plum type dual-purpose), electric control system of continuous casting and rolling mill.
