Abstract：Aiming at the problem of insufficient gas flow of casthouse dust extraction system in a steel mill, the analysis shows that the design of the right angle and the Z-shaped bend in the outlet of the dust collector is unreasonable, which leads to the loss of local pressure. The improvements will be the implementation of the partition in the middle of the fan outlet pipe, and a smooth transition from gas shutter to the outlet of the dust collector. The simulation results for the position show that the pressure loss after improvement is reduced to 523.4 Pa from 716.7 Pa and the gas flow is stable. After the project was carried out, the air volume of the dust-fan was increased to 1 040 000 m3/h from 700 000 m3/h.
