4, the present invention is easily compound, conjugation is high.
5, the continuous casting and rolling board assembly line just improves slightly and can produce.
6, be suitable for extensive, the large batch of manufacturing.
Continuous casting continuous rolling composite metal board of the present invention is characterized in that one deck is a stainless steel at least, and another layer be a carbon steel, alternately connect to form, or two outer for the stainless steel intermediate layer be that carbon steel replaces connection mutually and forms.Final is rectangular composite stainless steel plate.
The used capital equipment of the present invention is made up of an electric furnace more than at least two and a cover continuous casting tandem rolling board assembly line.Smelting stainless steel water of two electric furnaces, another melting carbon steel water, the ratio that reaches in certain sequence is cast to resulting continuous casting continuous rolling composite metal board in the continuous casting and rolling steel plate production line.
Description of drawings:
Fig. 1 is a production technology structural representation of the present invention;
Fig. 2 is a double-level-metal plate schematic diagram of the present invention;
Fig. 3 is a three-ply metal schematic diagram of the present invention;
The specific embodiment
Below in conjunction with accompanying drawing implementation column of the present invention is done to describe in further detail.
As seen from Figure 1, Figure 2, the present invention is provided with double-metal layer more than at least two layers (14) on the continuous casting and rolling board assembly line, and continuous casting continuous rolling composite metal board (15) (16) alternately superposes.
Described double-metal layer is that stainless steel layer (15), carbon steel layer (16) stack connect.
Described metal level can also be that stainless steel layer (17), carbon steel layer (18), stainless steel layer (19) mutual superposition connect.
Every title is among Fig. 1: stainless steel water bag (1), stainless steel water tundish (2), stainless steel water crystallizer (3), electronics agitator (4), carbon steel ladle (5), carbon steel water tundish (6), carbon steel water water cup (7), carbon steel water crystallization device (8), the cold-zone is propped up and led device (9), straightening machine (10), mangle (11), cutter sweep (12), roller-way (13), continuous casting and rolling composite stainless steel plate (14).
Its processing step of the manufacture method of continuous casting continuous rolling composite metal board of the present invention is:
The electric furnace of a more than at least two, a smelting stainless steel water, another melting carbon steel water.
B reaches the qualified stainless steel water of cast temperature, inject crystallizer (3) with ladle (1) by tundish (2), the dummy ingot device front end of crystallizer (3) end opening is set in the stainless steel water of crystallizer (3) lower end, stainless steel water in the crystallizer (3) is raised to when requiring height, when stainless steel water reaches critical-temperature, stainless steel reaches critical condition, starting dummy ingot device pulls down stainless steel billet, stop when moving the end opening of crystallizer (8) to, be linked together with the dummy ingot device of crystallizer (8).
C is reaching the qualified carbon steel water of cast temperature, inject in the crystallizer (8) by watering cup (7) by tundish (6) with ladle (5), carbon steel water in the crystallizer (8) and the casting of the stainless steel of another side critical condition are linked together, when carbon steel water is raised to the requirement height, the dummy ingot device upper end of crystallizer (8) end opening and the interior lower end of crystallizer (8) carbon steel water-setting are admittedly together, when carbon steel water reaches critical-temperature, carbon steel reaches critical condition, dummy ingot device starting being connected in crystallizer (8) end opening pulls down compound plate slab.The speed of dummy ingot device is at 3-6 meters/minutes, according to thin, in, slab and width and draw steel speed surely.
D can use the same method, and adds a crystallizer compound again one deck stainless steel on carbon steel again.
E leads device (9) plate slab and solidifies gradually when composite steel sheet billet props up by the cold-zone by electronics agitator (4) (crystallizer 8 following), roll the gauge of regulation to straightening machine (10) to mangle (11), by cutter sweep (12) cuttolength, produce qualified continuous casting continuous rolling composite metal board (14) through conveyor roller (13), obtain rectangular composite stainless steel plate at last.
This process using the state-of-the-art continuous casting and rolling technology technology of steel industry, with two-step crystallization method of the present invention, the continuous casting continuous rolling composite metal board quality of being produced is even, and equipment investment is little, output is big, easy to operate, cost also reduces about 30% than traditional handicraft method.
