Feb 03, 2015 Refractory mixes are mixed with a minimal amount of water (up to 10 %), then pressed into steel moulds under pressures from 3.4 MPa to 10.3 MPa by hydraulic presses or compressed air rams. Drying and firing Wet bricks from moulding or cutting machines contain a large quantity of moisture, depending upon the shaping process.
crushing, grinding pass through magnetic separator to eliminate the free iron impurities. The ideal firing temperature of green refractory bricks made of sillimanite grains as a major raw material is 1450 - 1500 O C, to be fired either in a batch type or a tunnel kiln. The soaking time will vary depending

Apr 26, 2017 From the standpoint of the comparison of the melting points of different refractories, the first is the better, but it involves the labor and time of fine grinding the second is the more feasible and, for a large variety of materials, when a cylindrical specimen is used, grinding to pass an 80-mesh screen appears to be suitable.
The refractories were both shaped and unshaped (tables II and III).9 Except for the silicon carbide bricks, they were all of the oxide variety. Two of the refractoriesone a magnesia brick, the other a spinel castable contained graphite. (They were chosen for their high thermal conductivity although graphite does inhibit slag
