Analysis of the advantages and disadvantages of continuous casting production
The advantages of continuous casting can be simply understood as; simplifying the production process, continuous casting can directly obtain a slab with a certain cross-sectional shape, eliminating the need for the entire mold ingot casting, molding, soaking, and initial rolling.
Advantage:
(1) Energy-saving. Continuous casting saves one heating and one tie
(2) Improve working conditions and increase labor productivity. Continuous casting has a high degree of automation, saving a lot of manpower. The ingot casting is interleaved with manual operations from the entire mold, ingot casting, demolding, and initial piercing. The degree of automation is low and the workers’ working conditions are poor.
(3) Good quality. Compared with ingot, continuous casting slab has uniform internal structure, compactness, less segregation, stable performance, and fewer surface defects.
(4) low production cost. (The continuous casting equipment is simple, eliminating the need for the initial rolling machine, soaking furnace, and saving fuel power and manpower)
Shortcoming:
(1) It is not flexible to produce small batches of billets with multiple specifications. (The mold needs to be replaced, the mold is expensive, the equipment of the continuous casting machine is more complicated, and the technical level of management and operation is high, and it is not suitable for frequent replacement)
(2) The continuous casting of boiling steel and high alloy steel still has certain difficulties.
