China’s mineral supply squeeze continues to challenge refractory producers. A ra

With the rapid progress of steel technology in the world,the major steel enterprises and users have a further demand for steel quality.Through the theoretical analysis of refining slag,it can control the refining process more effectively and guide the improvement of refining process.

Our Calcined bauxite with Al2O3 60-88% produced in rotary kiln and round kiln,output is more than 5000mts per month.Our factory is equipped with full rage facility and machinery ,including kilns for firing raw bauxite,crushers, roller mills and Raymond mills etc

At present, most steel plants in the world generally adopt Ladle refining, to reduce gas inclusion and make molten steel evenly, in order to realize high yield, high quality and low cost steel- making. So Calcium Aluminate slag is designed and manufactured to meet the above requirement and take a very important role in steel refining.

Features and advantages of our Refractory grade calcined bauxite : 1）low iron (Fe2O3) content ,less than 2.0%, 2)big bulk density 3) other impurity is very low,as we select raw material for one time and second time after discharge from furnace 4)efficient supplying capability 5) competitive price and stric

We manufacture different grades of pre-fused calcium aluminate slag: CaO-Al2O3 normal grade calcium aluminate slag;CaO-SiO2-Al2O3-MgO high magnesium grade calcium aluminate slag;Al2O3-CaO high alumina grade calcium aluminate slag;A2O3-CaO low Titanium grade calcium aluminate slag;Al2O3-CaO low silica grade calcium aluminate slag

Expanded perlite is white color material with multi applications ，which is processed by perlite sand after preheating then expansion at once in professional electricity furnace,its inside structure is in honeycomb shape.Its expansion rate is about 10-30 times..

We have CA50 A600,CA50 A700,CA50 A900,CA60,CA70,CA80 for your different application.its main mineral phase is CA,CA2,C12A7,C2AS
