Selection of ladle According to the smelting conditions, there are two types of ladle: standard type and short and fat type. 1、Heat transfer calculation Establish the mathematical model of ladle, according to the structural characteristics of the ladle, the heat transfer calculation of the ladle to do the following assumptions. 1) The wall of ladle […]
Refractory materials actually have different applications in various industries! However, their most common applications are in the following five areas. (I) Steelmaking system The steelmaking system includes equipment such as converters, electric furnaces, off-site refining furnaces, ladles and tundishes. In electric furnaces, dry vibrating materials, prefabricated or cast-in-place furnace covers or furnace cover triangles and

The strength of granular materials in castables is generally higher than the strength of the hardening body of the bonding agent and the bonding strength between the granules, so the room temperature strength of castables actually depends on the strength of the hardening body of the bonding agent. Changes in strength at medium and high
