Definitions
- the method further comprises: feeding the bloom strands through respective straightening rollers; operating each rolling mill at a speed based on a reference speed of the straightening rollers of the particular bloom strand fed to that rolling mill.
- Using the speed of the individual straightening rollers for each continuously cast strand as a reference speed for the rolling speed of the rolling mill for that strand in this way enables the billets to be reliably hot rolled and the material flow balance to be maintained on a strand-by-strand basis.
- the angle of the axes of the subsequent rolling mill stands is set at 90 degrees to each other. Arranging the cantilevered rolling mill stands in this way allows the rollers to access the bloom strands from away to the sides of the bloom, reducing the extent to which the rollers and the rolling mill housing interfere with the space immediately surrounding the cast blooms. Further, by alternating the axes of the rollers in this way, the rolling mill housings and stands can be offset from each other and/or positioned alternately above and below the cast blooms allowing the rollers to be positioned close to each other axially along the strand, allowing the rolling mill to occupy a short length along the strand such that the cast strand can be rolled at a uniform temperature without significant cooling between the rolling mill stands.
- the rolling mill and each rolling mill stand is selectably operable or engageable with the cast blooms, allowing the bloom strands to be selectably hot rolled into billets optionally of varying sizes.
- This allows the output of the continuous casting machine to be selectably variable in size, allowing production to adapt readily to demand, for example, fluctuations in demand in domestic and/or export markets for cast blooms and (rolled) billets.
- each of the continuously cast strands 1 18 is then passed through sequences of pairs of individual straightening rollers that guide the strands to extend in a horizontal direction and straighten the strands as they move along between the rollers and cool and further solidify.
- the continuous casting machine 1 10, and the permanent moulds 1 16 in particular are configured such that the strands 1 18 are formed as blooms having a cross sectional area above 230 square centimetres, in this case 240mm by 240mm square.
- protective cooling or insulating jackets can be provided around the housing 158 for the bearing supports and/or the motor and/or drive mechanism 156 for each cantilever rolling mill stand 152. Motors may be arranged to individually drive each of the rollers 154 for a given cantilever rolling mill stand 152.
- Each rolling mill 150 is configured to operate at a speed based on a reference speed of the straightening rollers of the particular bloom strand 1 18 fed to that rolling mill. This ensures a balance to the flow of material through the rolling mills 150.
