Continuous roll casting technology of difficult-to-deform copper alloy plate and strip blank

Abstract

The invention discloses a continuous rolling casting technology of a difficult-to-deform copper alloy plate and strip blank. The technology comprises the following steps: adding raw materials into a furnace, smelting and refining the raw material, standing at thermal insulation condition, carrying out crystallization, casting blanks, cooling by water, drawing, milling in two surfaces, performing random horizontal shearing, rolling by a periodic rolling machine, cutting the head, and reeling. In the provided technology, an induction furnace, a stationary furnace, a horizontal continuous casting machine, a milling machine, the periodic rolling machine, and a reeling machine are needed, the thermal insulation temperature is 1150 to 1200 DEG C, the temperature is maintained for 20 minutes, the casting blank cooling temperature is 30 to 50 DEG C, the casting speed is 0.2 m / min, the thickness of milling surface of each surface is less than 1 mm, and the rolling processing rate is 70 to 95%. The deformation amount of product is great, the mechanical performance of the plate is excellent, fine crystal organization can be obtained after a heat treatment, the stability of the technology process is high, the manufacturing and exchange of tools are simple, and the provided technology can roll a plurality of alloys and has the advantages of less energy consumption, low production cost, and high production efficiency.

Description

[0001] technical field [0002] The invention belongs to the continuous casting and rolling process of copper alloy strip blanks, in particular to a continuous casting and rolling process of difficult-to-deform copper alloy strip blanks. [0003] Background technique [0004] There are two traditional processes for the production of hard-to-deform copper alloy strip blanks, one is semi-continuous ingot casting→soaking→hot rolling→heat treatment→cold rolling; the other is horizontal continuous casting→heat treatment→cold rolling→heat treatment→cold rolling rolled. The amount of deformation of these two methods is small, and the mechanical properties of the product need to be improved. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a continuous casting and rolling process of hard-to-deform copper alloy strip blanks, which is easy to operate. [0007] The cont...
