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
Technical field
The invention belongs to copper alloy plate made-up belt continuous casting and rolling technique, be specifically related to a kind of difficult wrought copper alloy strip blank continuous casting and rolling technique.
Background technology
The traditional handicraft that difficult wrought copper alloy band blank is produced has two kinds, and one is semicontinuous ingot casting → soaking → hot rolling → heat treatment → cold rolling; Another kind is horizontal casting → heat treatment → cold rolling → heat treatment → cold rolling.These two kinds of method deflections are little, and product mechanical performance has much room for improvement.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of difficult wrought copper alloy strip blank continuous casting and rolling technique is provided, easy to operate.
Difficult wrought copper alloy strip blank continuous casting and rolling technique provided by the invention, technological process comprises: batching shove charge → melting refinement → static insulation → crystallization → strand → water-cooled → traction → two-sided milling → servo-actuated is horizontal cuts → cycle mill milling → crop → batch.Wherein, required device comprises induction furnace, static stove, horizontal caster, Milling Machine, cycle milling train, coiling machine, holding temperature is 1150 ~ 1200 DEG C, insulation 20min, slab cooling temperature is 30 ~ 50 DEG C, casting speed is 0.2m/min, and every facing cut face thickness is less than 1mm, and Reduction by rolling is 70 ~ 95%.
Difficult wrought copper alloy strip blank continuous casting and rolling technique provided by the invention, its beneficial effect is, can obtain uniform macrostructure and minimum segregation, deflection is large, Strip good mechanical performance, can obtain fine grained texture after heat treatment, stable technical process is high, and tool making and replacing are simply, can the multiple alloy of rolling, energy consumption is little, and production cost is low, and production efficiency is high.
Detailed description of the invention
Below in conjunction with an embodiment, difficult wrought copper alloy strip blank continuous casting and rolling technique provided by the invention is described in detail.
Embodiment
Technological process comprises: batching shove charge → melting refinement → static insulation → crystallization → strand → water-cooled → traction → two-sided milling → servo-actuated is horizontal cuts → and cycle mill milling → crop → batch.Wherein, required device comprises induction furnace, static stove, horizontal caster, Milling Machine, cycle milling train, coiling machine, holding temperature is 1150 ~ 1200 DEG C, insulation 20min, slab cooling temperature is 30 ~ 50 DEG C, casting speed is 0.2m/min, and every facing cut face thickness is less than 1mm, and Reduction by rolling is 70 ~ 95%.
