Refining molten steelin thesteel making plantthe product has been put into the surface of the molten steel temperature dro over time, and prevent re-oxidation for the purpose of prevention against the rules used in the rice husk.
7.Necessary conditions
1) Rice huskisteeming ladleof molten steel surface and the initial injection is formed when the molten metal inside the tundish to put the appropriate amount by the end of the casting temperature of the thermal insulation shall be maintained.
2)shall minimize to contamination to the molten steel by binder
3) the rice husk for casting pit must be maintained performance to thermal insulation in order to prevent shrinkage defects.
8.physical properties
1) rice husk should be corresponding to the high heat insulating property of powder
2)when put into flames, the smoke and dust generation must be less and should be good spreadability
3) Arising out of the gas from products or from the molten steel will not be remaining should be good air permeability
