Silverthorne Refractories Inc has over 30 years of combined experience in manufacturing custom engineered Synthetic Slags, Ladle Covers and Tundish Fluxes tailor made to the customers specifications for steel making production.

Our custom designed Synthetic Slags can be added to the ladle either during or after tap at the steel making furnace or used at the LMF,RHD,VAD or AOD. Our Ladle Covers have excellent thermal insulation properties with good flowability and provides protection to the ladle refractory lining which makes these products very cost effective.

Our custom designed insulating tundish fluxes are formulated for use on aluminum or silicon killed steel grades. They also provide excellent protection from re-oxidation and non-metallic inclusion absorption.
