Dalian ZhongTang can design and produce pre-heating required and heating-free shrouds accord to the site needs and condition of the steel mill.
Dalian ZhongTang can also provide non-protective fired and pre-heating free shroud. Under a special firing process, the shroud generates a de-carbonized layer with micropores, giving better thermal insulation and creating a favorable temperature gradient for better thermal shock resistance and abrasion resistance. This product is most suitable for low and ultra-low steel and alloy steel production in particular.
