The casting process in molds requires the best refractory and auxiliary materials possible for the perfect execution of it. SQ Insertec manufactures and distributes a multitude of refractory products for casting in steel ingots.
Solid coverings with different geometries or powdery.
Not shaped (dust).
Added just after pouring, they guarantee a good feeding without shrinking, obtaining healthy ingots.
Union of siliceous and silicoaluminous pieces
Base silica. Linked to the air
Union of high alumina pieces (Spoons, buzzer closures).
70% Alumina, Cold set.
SIDERCOL 611 –P
Mortar repairs of small thickness in tundish, piquera.
Fine-grained. Easy to apply
Bonding of sliding plates.
Use up to 1750ºC.
SIDERCOL 25 GA1
Union buzzers, casting plates.
30% cement, prevents adhesions of parts.
SIDERCOL 26 ASG
Easy assembly and hot disassembly of porous plugs.
Fine grain, quick and easy application.
Thanks for its insulation performance, Hot Top products avoid shrinkage and offer good ingot directional solidification.
Avoid the heat lost from the top surface of the ingot, therefore it avoid shrinkage and provide a good sound ingot.
Pre-shaped, avoid the heat lost from the top surface of the ingot, therefore it avoid shrinkage and provide a good sound ingot.
The preshaped device is set between the mould and the bottom plate to prevent finning and steel break out (leakage) during teeming.
