Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 298-2007 "high titanium slag", compared with the present standard YS/T 298-2007 main changes are as follows.
--- High titanium slag grades from four to seven; for CaO, MgO content of the claim, respectively, an increase of Cr2O3, V2O5,
SiO2, Al2O3 content requirements;
--- Modify the product size;
--- Increasing the moisture content of the product and test methods;
--- Modify the inspection and acceptance;
--- Modify the group batches.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points.
This standard was drafted. Yunnan Xinli Nonferrous Metal Co., Zunyi Titanium Co., Ltd., the aerospace He (Tangshan) Co., Titanium

This standard replaces the standards previously issued as follows.
--- YB2401-1978, YS/T 298-1994, YS/T 298-2007.
High titanium slag
1 Scope
This standard specifies the requirements of high titanium slag, test methods, inspection rules and signs, packaging, transportation, storage, quality certificates and orders
(Or contract) content.
This standard applies to ilmenite as raw material for the production of electric furnace smelting titanium tetrachloride, synthetic rutile and titanium dioxide used in high
Titanium slag.
