Continuous casting open mold fluxes

Detailed introduction

The mold flux developed by Tangshan Guoliang Special Refractories Co., Ltd. aims at supplying heat to the meniscus of molten steel in the mold. It has the ability to generate heat. The heat of molten steel can be used to initiate exothermic reaction. The heat generated by the reaction can control the temperature drop of molten steel in the mold and make the solidified shell produced in the initial stage develop soundly to a greater extent, thus reducing the occurrence of bad billet opening.
Continuous casting open mold fluxes are suitable for common steel, excellent carbon, low alloy and so on.
Continuous casting open mold fluxes suitable for cross section: billet and slab.
