Practice of Improving Speed of Billet Caster with 8 Meter-arc-radius in Ansteel
With regard to the problem that the low speed of the billet caster with 8 meter-arc-radius could not meet the production requirements,the key factors for influencing to improve the caster speed were analyzed.After that,such measures as increasing the length of a mould,updatin g the water supply pump to the mould and the water nozzles in secondary cooling zone,expanding the diameter of tubes used in secondary cooling zone and optimizing the system temperature were taken,the casting speed of the billet caster increased to 3.5 m/min from 2.8 m/min,and the billet quality pass percent was up to 99.95%,and thus stable production by the billet caster at high speed was realized.
