Effect of chromite additives on the properties of a high-alumina tamping mass

Abstract

As a result of the reconstruction of the shop, the furnace was shut down for the main maintenance after being used for 1 year.When the lining was inspected, it was established that it was still in a reasonable working state.The wear on the walls in the slag zone was 40-60 mm (20-25% of the original thickness).There was only very slight wear (5-10mm) below the level of the slag zone.As a result of the work carried out, a Soviet lining for LFR-2 CTO baleout pot furnace has been developed and tested.The resistance of this lining is as good as that of the lining made from imported mass.

Effect of Additives and Carbon Resources on Thermal Shock Resistance of Spinel-C Material

“…However, the RSR and CMORTS of B4C# are both the lowest. This result is different from other system [1,2]. The main reason is that the density of amorphous B2O3 is 1.795 g/cm 3 , and the density of liquid phase B2O3 is 2.460 g/cm 3 [3], the rapid expansion of the volume from liquid to solid during waterquenching destroys the micro structure of the specimen.…”

“…It can be seen that: (1) The phases in all specimens are spinel, graphite and corundum. (2) The diffraction peaks of B4C of B4C# and Al-Si-B4C# cannot be detected. (3) The diffraction peaks of aluminum of Al-Si# and Al-Si-B4C# cannot be detected.…”
