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
Heating furnaces for medium and heavy plates are divided into continuous heating furnace, chamber heating furnace and soaking pit furnace according to their structures.
Heating furnaces for medium and heavy plates are divided into continuous heating furnace, chamber heating furnace and soaking pit furnace according to their structures.
(1) The content of harmful elements phosphorus and sulfur shall be as low as possible;
(2) The range of upper and lower limits of element content should be as small as possible, especially the content of carbon element;
Some defects may appear on the surface of flat ingots, blooming billets or continuous casting billets, which are used as raw materials for the production of medium and thick steel plates
(1) The thickness of raw materials shall be as small as possible, which is conducive to the improvement of the efficiency of rolling mills and heating furnaces.
