A brief introduction of Chrome Iron Ore:

Chromite sand also called chromite sand, with chromite based natural spinel, calcined at high temperature after crushing, grinding and sieving of various specifications of size, suitable for modeling (core) sand.

 Features & Benefits

• Excellent chilling characteristics can eliminate the need for metal chills

• Chipping, grinding, and overall cleaning costs significantly reduced

• Reduction of gas defects due to minimal binder requirements along with excellent permeability

• Preferred aggregate for large iron, steel, copper base and high alloy castings due to high resistance to penetration

• Excellent peel characteristics and good surface finish due to superior resistance to metal oxides and slag

• Thermal stability properties reduce expansion defects and enhance overall dimensional accuracy

 The Application of chrome iron ore:

1.Iron ore is used as sand casting, special sand casting, with heated volume stability, good thermal stability, high thermal conductivity, high refractoriness, low expansion coefficient, according to the needs of machining, casting size uniform, clean and dust-free, has good fluidity, dispersion characteristics, chromite sand in foundry production mainly used in large steel casting sand surface, prevent the casting surface adhering sand; secondly the mill for refractory casting coating; chromium ore is chill material in the other (core) can be part of the cold iron.

Chromite sand and molten metal contact not only with anti alkaline slag good effect, no chemical reaction with ferric oxide, and itself has a solid phase sintering, have good anti permeability, anti adhesion, prevent the infiltration of molten metal, avoid sand defects. It is suitable for the original sand and coating of various stainless steel, alloy steel and carbon steel.

2.Iron ore as abrasive, with moderate hardness, high toughness, high temperature resistance, thermal stability, hardness is less than corundum, its low cost and high efficiency in blasting large ships, steel bridge rust, surface treatment of sand blasting process are very popular. Multi metal products used for coarse grinding before electroplating; stainless steel, metal products, optical glass, wood products, polishing and sandblasting, resin grinding wheel is manufactured, cutting film, novel abrasive emery cloth. Is manufacturing resin cutting blade, angle grinding and coated abrasives economic materials etc..

3. 1-3mm 3-5mm section sand is the high quality material for the sand aggregate of the ground floor under the antiskid pavement and the coal mine pit.
