The Mechanical Performance Experiments of Blast Furnace Hearth Ramming Material and Carbon Brick Refractory Mortar

In this paper, the mechanical properties experiments of BF hearth ramming material and carbon brick refractory mortar were carried out. The compressive strength experiments of refractory mortar at different curing temperatures and the resin and asphalt combined with ramming material at different molding pressures and curing temperatures were carried out respectively. The conclusions are as follows: (1) In the experiment temperature range, the compressive strength of resin combined with ramming material is significantly higher than that asphalt under the same conditions. (2) With the increase of temperature, the compressive strength of resin combined with ramming material and refractory mortar first increased and then decreased, while the asphalt combined with ramming material increases gradually.
