一种上引法铜带坯结晶器及铸造方法
An upward casting copper strip billet crystallizer and casting method. The crystallizer comprises an upper crystallizer section and a lower crystallizer section connected by fastening screws and sealing gaskets.
The lower crystallizer section incorporates a copper block substrate having S-type water channel grooves machined in the upper portion and interconnecting water passages in the middle-lower portion. The copper block substrate is connected at one end to a graphite mold via lower passages in the substrate.
The upper crystallizer section comprises a front plate and a rear plate welded from stainless steel, each provided with single-layer continuous S-type water channel grooves. Copper strip billets are positioned within the upper passages of the front and rear plates. The copper cover plate is provided at its top with two symmetrically arranged water inlet and outlet ports. The upper and lower crystallizer sections are interconnected by connecting water pipes.
The patent abstract states that the resulting copper strip billet has clear crystallization lines, predominantly equiaxed grains, regular arrangement, and uniform grain size, with the stated aims of more stable performance, easier processing, and higher finished-product yield.
- Dual-section crystallizer structure (upper stainless steel + lower copper block) with sealed, bolted connection
- S-type water channel groove geometry in both upper and lower sections — optimised for uniform heat extraction
- Single-layer continuous cooling circuit in the upper section; interconnecting passages in the lower copper block substrate
- Graphite mold connected directly to the lower copper block via substrate passages
- Symmetric dual water inlet/outlet ports on the copper cover plate
- Patent-stated result: clear crystallization lines and predominantly equiaxed, uniformly sized grains
Patented Structure and Performance Reference
The patent describes an upper and lower crystallizer section, S-type cooling-water channels, and the connection to a graphite mold. Read the public patent record for the drawings, claims, and casting method.
This patent applies to the upward copper strip billet crystallizer and associated casting method. It is not a patent for semi-continuous billet lines, resistance furnaces, vacuum furnaces, or every product sold through Mivo. The patent description gives a 120 mm/min example at a 220 x 12 mm section and cites 60 mm/min for an existing same-section reference. Project performance remains subject to the agreed material, section, cooling, stable-run, and test conditions.
