After 6 months from the first order to Danieli Davy Distington, Baosteel awarded the order for a second thick slab caster, to be installed in No.3 plant in Shanghai.

The contract calls for the supply of a single-strand machine exceeding 1.5 Mtpy of qualified slabs in special steels,structural steels, vessel, boiler and ship application steels. Slab sizes are 200 and 250 mm in thickness, 1500 to 2300 mm in width.The main features of the machine include:

- Vertical curved design with a vertical length exceeding 2.6 m,a 9.5 main radius and continuous bending and unbending roll diagram.

- Top feeding dummy bar.

- Complete breakout prevention system with thermal mapping of the mould.

- State-of-the-art INMO mould,including in-line width adjustment during casting.

- Hydraulically operated oscillator.

- OPTIMUM type segments, designed for the application of Dynamic Soft Reduction process.

- Air mist secondary cooling, controlled by a dynamic model.

- Complete automation system including predicting mathematical models for Liquid Pool Control (LPC) and Solidification process used for Dynamic Soft Reduction (DSRC) and Dynamic Secondary Cooling (DSC) system.

Of particular note,this is the 20th Danieli slab strand (8 in China) adopting INMO mould technology, the last generation patented mould,designed with superior zero-clearance guidance system for outstanding slab surface quality.

This second order awarded to Danieli in just a few months by Baosteel (the largest Chinese steel producer) confirms the leading technical position of Danieli Davy Distington as supplier of superior slab casting equipment,as well as customer satisfaction reached during the execution of the contract of the caster for plant No. 4, presently under advanced design stage.
