Standard Silicon Briquette Si50A

A briquette is silicon powder pressed under high force into lump or flat ball shape, and theres no binder chemistry you have to account for afterwards. We run two marks off the same press, Si50A and Si50B, both starting at 50 percent silicon.

Compared with loose powder it dusts far less, and it does not blow out of the converter mouth, which is usually the reason a shop tries it in the first place. If youve ever fed fine silicon powder by hand you know the cloud it makes.

Deoxidation is quick and the slag collection is good, so part of the ferro silicon you normally dose can come out of the recipe. Inclusion count comes down as a side effect, and crews tell us that shows up later as better hardness and elasticity in the finished steel.

Most of the shops that switched did it for the cost sheet, not because they wanted to experiment. On our figures the metallising cost lands somewhere in the 15 to 30 percent band cheaper. We would rather you take a trial bag, run one heat and check the recovery yourself before you commit to a container.

Anyang Mingrui Silicon Industry Co., Ltd, Anyang, Henan. The pressing line and the grinding line sit on the same site, so the powder that goes into the balls is ours and we can tell you the assay of that lot. Loading out of Qingdao or Tianjin on FOB, CIF or CFR terms, usually 7-10 days after the deposit, SGS inspection if you want it.

Q: Which mark should I start with?
A: Si50A if your carbon ceiling is tight. Si50B if you also want the carbon and dont mind the difference in Al.

Q: Minimum order?
A: One pallet or a single trial bag is fine to start. Wed rather you test on one heat first than buy a container blind.
