Refractory material drying and firing_SINOSTEEL REFRACTORY
Dec 04, 2017 · Refractory drying process is broadly divided into: drying of raw materials and molding of semifinished products after drying. If the moisture content of soft clay exceeds 12%, it will be hard to crush if it is not dried, which will reduce the mill's production capacity. If the brick into the kiln water is too large, prone to cracking in the ...
Chromium in Refractories | EVISA's Links Database
The mineral chromite is the only ore of chromium 1. About 15% of the total world chromite consumption is from the refractories industry 2. A typical analysis of a chromite suitable for refractory purpose is 38 to 48 percent Cr 2 O 3, 12 to 24 percent Al 2 O 3, 14 to 24 percent Fe 2 O 3, 14 to 18 percent MgO, and less than 10 percent SiO 2.

Chromium | Cr
Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is present in the environment in several different forms. The most common forms are chromium(0), chromium(III), and chromium(VI).No taste or odor is associated with chromium compounds. Chromium(III) occurs naturally in the environment and is an essential nutrient.

AISI 304: As per our recommendation, AISI 304 can be used in the area with temperature less than 700 o C. AISI 310: Due to the increase in Nickel and Chromium as compared to AISI 304, this can be used in the temperature up to 1,100 o C. However, due to high nickel content, AISI 310 is weak against sulphur, which tries to combine with the nickel of the alloy and weakens the alloy.
