Mold flux

Introduction

 

Casting mold flux (also known as “casting powder”) is the heart of continuous casting, which plays a key role in continuous casting process. Excellent mold flux performance could greatly improve surface quality of casting blank and casting speed.

Multiple kinds of calcium metasilicate and necessary raw materials mixed together per client’s specific steel making demands to produce mold flux.

Casting Trading company provide not just Mold flux for clients, also customized design based on clients’ actual steel making demands. Over 30 years of casting mold flux production experience committed us to provide professional technical support & solutions for all our clients in domestic and overseas.

 

Five major effects of mold flux:

 

(1)Good lubrication for casting billets to smoothly pulled out of the crystallizer.
(2) Good insulation capacity and good diffused ability
(3) Heat transfer control, improve the heat conduction rate and uniformity.
(4) Prevent molten steel from secondary oxidation
(5)Absorb the inclusions to improve the cleanliness of the steel

According to the different types of slab and carbon content etc. Mold flux series products could divided into following types:
