Embodiment 1

[0059] Taking the copper-clad steel composite wire rod as an example, adopt the equipment of the present invention to process and produce the copper-clad steel composite rod, and select the outer diameter of The Q345 bar is used as the solid matrix metal 9 to be composited, and the industrial pure copper is used as the liquid cladding metal 10. The total diameter of production Copper-clad steel composite rods, where the wall thickness of the cladding metal is 2mm.

[0060] 1. First, clean and dry the outer surface of the Q345 bar to be compounded, heat the industrial pure copper to 1100°C to melt, and keep it warm for 60 minutes;

[0061] 2. After the Q345 bars to be compounded pass through the guide bracket 7 and the flow distribution device 6 in sequence, they are fed into the pass smoothly, the casting speed is set at 3.5m / min, and the multi-roll continuous casting and rolling equipment is turned on to enter the idling standby state. At the same time, the liquid industri...

Embodiment 2

[0065] Taking copper-clad titanium equilateral hexagonal composite rod as an example, adopt the equipment of the present invention to process and produce copper-clad titanium equilateral hexagonal composite rod, and select the equilateral hexagonal titanium alloy rod with a side length of 10mm as the Composite solid matrix metal 9 and industrial pure copper as liquid cladding metal 10 to produce copper-clad titanium equilateral hexagonal composite rods with a cladding wall thickness of 2 mm.

[0066] Such as Figure 9 As shown, unlike the production of high-conductivity metal cladding materials with circular cross-sections, when producing copper-clad titanium equilateral hexagonal composite rods, the first main casting roll unit 501, the first auxiliary casting roll unit 502 and the second On the surface of the casting roll sleeves 5013, 5023, 5033 of the auxiliary casting roll unit 503, there are circumferential holes 500 rotating along the axis. The cross section of the circ...

Embodiment 3

[0072] On the basis of the present invention, when the number of casting roll units in the multi-roll casting unit 5 is 4, it is a four-roll continuous casting equipment. Such as Figure 10 as well as Figure 11 As shown, the casting unit includes a first main casting roll unit 501, a first secondary casting roll unit 502, a second secondary casting roll unit 503 and a third secondary casting roll unit 504, and the surface of the casting roll sleeve is provided with a casting The axis of the roll unit rotates around the circumferential hole, the cross section of the circumferential hole is arc-shaped, the first main casting roll unit 501, the first secondary casting roll unit 502, the second secondary casting roll unit 503 and the third secondary casting roll unit The circumferential slots of the casting roll unit 504 jointly form a circular pass at adjacent positions, the circular pass is for the composite solid matrix metal 9 to pass through, and the diameter of the circula...

Abstract

The invention provides a multi-roll continuous casting and rolling equipment and method for preparing high-conductivity metal coating materials. The multi-roll continuous casting and rolling equipment includes a transmission system, a frame, a frame base, a pouring unit for pouring liquid coating metal, Multi-roll casting unit, flow distribution device, guide bracket and annular cooling device. The multi-roll casting unit includes the first main casting roll unit, the first secondary casting roll unit and the second secondary casting roll unit. The three together form a pass structure. The outlets converge and enter the pass structure of the multi-roll casting unit together, and form a high-conductivity metal cladding material after solid-liquid casting-rolling composite forming in the multi-roll casting unit. The invention combines the rapid solidification technology with the rolling technology, improves the cooling uniformity in the circumferential direction by increasing the number of casting rolls, and finally can improve the comprehensive performance of the product, the uniformity of the product quality and the production efficiency.

Description
