chromite compressive strength

Compressive Strength and Creep Behavior of a

The compressive strength of a magnesium chromite refractory in nitrogen was measured by rapidly loading specimens to failure at several temperatures up to 1600 O C. Strength retrogression was observed at temperatures above 1200°C. The creep behavior of the refractory in nitrogen was measured as a function of compressive stress in the range from 1.4 to 5. 6 MPa and as a function of temperature

2016-12-27  By comparing the compressive strength results with the volatile contents of the reductants, it appears that a higher volatile content caused a decrease in pellet compressive strength. Furthermore, it is apparent that in every instance where the maximum volatile content specification of 7.5 wt pct was exceeded, a dramatic decrease in the pellet compressive strength was observed.

Hot Compressive Strength and Deformation of Sand

Hot compressive strength and deformation of silica, olivine, zircon and chromite sand molds bonded by sodium silicate or bentonite were investigated. Sodium silicate bonded sand mold have the maximum hot strength at 200°C and 500°C, and bentonite bonded sand molds have it at 900°C. As sodium silicate and bentonite become soft above 500°C and 900°C,
