Melt type refining synthetic slag heat insulation Refractory Materials Iron and steel smelting

Product Profile

In 2001,we have desulphurizer Ba desulphur in order to adapt the LF refinery,which has better effection than Ca desulphurizer because of Ba’s special atom format. It has the proper of low melting point, speed melting the slag to reduce the Cao,CaF2,short the time of ladle furnace. The desulphur stable rate can be reach by 30%-80%(according to different customer),meanwhile it can also reduce the noisy polution and the wear of electrode.It has also a good effection of increasing the speed of the metallurgy way.

 In order to meet the supporting services of the metallurgical industry and the production of various steels, avoid the appearance of carbon-free particles. The product is made of carbon-free raw materials. It has high refractoriness and solves the problem of easy scaling. It has the advantages of excellent coating performance, strong heat preservation ability, scale formation after absorption of inclusions, no sticking to the wall, long heat preservation time, small amount of molten iron cooling, and no corrosion of the ladle wall.

The physical and chemical indicators

​Usage:

a. Put1/3 to 1/2 into the bottom of ladle, the position should be arround the shock zone, to avoid the harm to the purge plug.

b. Use the balance during tapping.

c. The recommended dosage is 4-10 kgs per ton steel,can be adjusted according to the original S content in the steel.

d. The consumption can be lower down to 3-5kgs per ton steel if with 5-7kgs CaO per ton steel.

Pay attention to the following items while using:

a. Please Skim slag while using.

b. Please add this product continuously in order to desulphur better under the enough reaction area and time.And the ladle should have corresponded purging stirring to help the reaction.
