What are the advantages and disadvantages of using bloom raw materials?

Advantages: the blooms are rolled by the bloomer with large ingots, so its structure is relatively dense, there is no as cast structure stress, and it can be heated at a higher heating speed than the ingots; Because the blooms have been compressed, there is no need to be limited by the compression ratio, so when the blooms are used as raw materials, the thickness of raw materials can be as small as possible. Therefore, the medium and heavy plate mill using blooms as raw materials has high output and good quality.

Disadvantages: the blooming mill has large investment and high energy consumption, and the comprehensive yield from ingot to steel plate is low.

What are the advantages and limitations of using continuous casting slab as raw material?

Advantages: the internal structure of continuous casting billet is denser than that of flat ingot, and the thickness dimension is smaller than that of flat ingot, so the output can be increased and the yield can be improved.

Limitation: due to the influence of continuous casting equipment, the width size and thickness size of continuous casting slab cannot be too many, which reduces the production efficiency of rolling mill and heating furnace. Due to the limitation of compression ratio, the thickness of thick plate with continuous casting slab as raw material cannot be too large.
