Abstract：
In order to carry out capacity replacement in X Steel Plant to enrich product structure,a new domestic multi-flow straight arc wide flat billet continuous casting machine is built,which can produce 165/180×(450~750)mm small slab with 5-strand at the same time.The design of the casting machine was novel,which integrated the characteristics of conventional double-flow slab and multi-flow rectangular slab.The new technologies,such as same-position profile-shaped ladle rotary table,double control mode of intermediate tank,radial extraction of dense row clamping section,up-down driving brand type pulling-leveller,new hydraulic vibration,L-shape flying hammer deburring machine,roller line optimization and dynamic water distribution for secondary cooling,which could be used for reference for the construction of similar continuous casting machines.Two years of production practice show that the machine is becoming more and more skilled in production and maintenance operation,the indexes meet the design requirements,the economic performance is superior,the surface of the casting billet has no defects,the internal quality is excellent,and the actual production effect is satisfactory.
