Thin slab (medium-thick slab) continuous casting and rolling is a rapidly developing hot-rolled strip production method since its practical application in 1990. What is its structure? We’ll introduce it to you today:<\/p>\n\n\n\n
By the end of 2005, nearly 40 thin (medium-thick) slab continuous casting and rolling production lines had been built worldwide. The main types include SMS’s CSP, DEMAG’s ISP, Sumitomo’s QSP, DANIEL’s FTSR, and Voestalpine’s CONROL, etc.<\/p>\n\n\n\n
Process Characteristics of Thin Slab Continuous Casting and Rolling<\/p>\n\n\n\n
The slab thickness in thin slab continuous casting and rolling is 50-90mm. The continuous casting and rolling equipment often uses a tunnel-type hearth furnace connection. Its technological characteristics are as follows:<\/p>\n\n\n\n
(1) 35-70mm thick slabs are selected for production based on different steel grades and required strip thicknesses;<\/p>\n\n\n\n
(2) High cooling intensity in the crystallizer results in short columnar crystals and refined grain structure in the as-cast state;<\/p>\n\n\n\n
(3) The roller hearth furnace allows for flexible control of the slab heating process;<\/p>\n\n\n\n
(4) The use of a plate coil box reduces the temperature drop of intermediate slabs and shortens the distance between the pre-finishing mill and the finishing mill;<\/p>\n\n\n\n
(5) The finishing mill uses a rolling speed similar to that of a regular finishing mill;<\/p>\n\n\n\n
(6) A close-range underground coiler can be added for producing thinner strips;<\/p>\n\n\n\n
(7) Suitable for producing thin-gauge strips.<\/p>\n\n\n\n
Technical Characteristics of Continuous Casting and Rolling of Medium-Thick Slabs<\/p>\n\n\n\n
The required slab thickness for continuous casting and rolling of medium-thick slabs is 100-150mm. A walking beam furnace is often used to connect the continuous casting and rolling equipment. Its technological characteristics are as follows:<\/p>\n\n\n\n
(1) The production efficiency of continuous casting is well matched with the production rhythm of continuous rolling;<\/p>\n\n\n\n
(2) It can handle significantly more flexible steel grades than thin slab continuous casting machines, providing greater flexibility in steel grades;<\/p>\n\n\n\n
(3) There is no problem of insufficient compression ratio when producing thick strip steel;<\/p>\n\n\n\n
(4) It is suitable for the transformation of traditional hot strip continuous rolling lines;<\/p>\n\n\n\n
(5) It is suitable for improving strip quality and expanding product variety.<\/p>\n\n\n\n
