1、外文资料Continuous casting machine is mainly composed of carrier of ladle, tundish, tundish carrier, mold, mold vibration device, secondary cooling device, throwing straightening machine, dummy device, cutting device, and casting out of the device and other parts.Ladle transporter is mainly include cast

2、ing and ladle rotating table in two ways, at present most of the new design of continuous casting machine based on ladle revolving platform. Its main function is carrying the ladle, and support the ladle pouring operations. Based on ladle rotary table can be replaced rapidly ladle, realize the conti

3、nuous casting furnace.Ladle and tundish between crystallizer is to receive the transition device, the liquid steel is used to stabilize the steel flow, reduce erosion of the shell in the mould by the steel flow; And make the flow of liquid steel in tundish is reasonable and appropriate long residenc

4、e time, to ensure uniform liquid steel temperature and non-metallic inclusion separation floatation; For multiple flow continuous caster by tundish shunt for molten steel; Even when pouring in furnace, storage of liquid steel in tundish in replacing the ladle play the role of cohesion.Carrier have i

5、ntermediate tundish charter and tundish rotary table, it is used to support equipment, transportation and replacement of tundish.Crystallizer is a special water-cooling steel mould, molten steel cooling in the crystallizer, preliminary coagulation, and form a certain thickness of billet shell, to en

6、sure that the slab is pulled out of the mould, shell not be leakage, defects such as deformation and cracks.Mould oscillation device is to make the mould to do reciprocating movement up and down according to certain requirements, in order to prevent the early green shell and mold adhesion was rippin

7、g.Secondary cooling device is mainly composed of spray cooling device and slab support device. Its role is: directly spray to the casting, the solidification completely; Through the clamp side guide rollers of slab with liquid core supporting and guiding role, to prevent and limit the slab deformati

8、on drum belly, and steel leakage accidents.Throwing the role of the straightening machine is overcome in the process of casting slab and the resistance of mold and secondary cooling zone, successfully casting out, and the arc slab straightening. The dummy device before pouring, it also will into the

9、 mold.Dummy device including dummy bar head and dummy bar two parts, it is used when the cast starting as the bottom of the living of crystallizer, blocked the mouth of the mould and make the liquid steel in the dummy bar head coagulation; By pulling machine traction, slab with dummy bar mouth pulle

10、d out from under the crystallizer. Dummy bar pull out of the machine, the dummy bar to take off, into the normal state of throwing.Cutting device is used in the casting process, marching to divide it into the specified length required.Casting out of the device including roller, pushing steel machine

11、, cooling bed, etc., by their complete slab conveying, cooling etc.Continuous casting machine can be classified according to a variety of methods:(1) according to the movement of the mould, casting machine can be divided into stationary (vibrating) and two categories. The former is now commonly used

12、 in the production of water, at the bottom of the exposure of copper crystallizer of normal characterized by continuous caster; The latter is a wheel with casting crystallizer such as type, belting leather continuous casting machine of the movement.(2) according to the appearance of continuous caste

13、r structure can be divided into vertical continuous casting machine, the bending type continuous casting machine , arc continuous caster (including straight mold more curved, straight arc, arc radius arc crystallizer, ) , horizontal continuous casting machine .(3) according to the shape and size of

14、slab section can be divided into: billet caster (cross section is not more than 150 x 150 mm small billet; more than 150 x 150 mm called bloom, rectangular cross section of the length and width of less than 3, also known as billet caster), figure 1-6 small billet caster is Mr Prodi arc, figure 1-7 a

15、rc generous slab continuous caster, figure 1-8 arc small billet caster; Slab continuous casting machine (rectangular slab section for its generous than the average in more than 3); Round billet continuous casting machine (slab cross section is round, diameter of 60 400 mm ); Profiled billet continuo

16、us casting machine (pouring special-shaped section, such as H, hollow tube, etc.); Party, combination of slab continuous caster (in a casting machine can cast slab can casting billet); Thin slab continuous casting machine (casting sheet billet thickness of 40 80 mm), etc.(4) according to the casting of steel liquid static head, the casting machine height (H) and vertical slab thickness (D) ratio, the size of the continuous casting machine can be divi
