Application of Ladle Castables

Application of Ladle Castables

Ladle Castables
Because the water content of the whole ladle castable is large, and the material structure is dense, the water is not easy to be discharged. Therefore, in the ladle baking process, the small heat is long, gradually warming up, preventing rapid heating, and the principle of roasting the fire is strictly prohibited, otherwise the ladle appears. It collapsed and peeled off. Bake with a baking machine and bake in a 72-hour system. The specific distribution is as follows:

Firstly, small fire stage: no less than 3 shifts, 24 hours (only 1/2 gas, no cover);
Secondly, medium fire stage: no less than 3 shifts, 24 hours (only 1/3 gas is added, plus a little wind, stamped);
At last, fire stage: no less than 3 shifts, 24 hours (open gas, add foot, cover)

Advantages of covering agent

covering agent
covering agent
1, Insulation covering agent is made of low thermal conductivity material composition, such as: expanded perlite, expanded graphite.

2.In addition to the low thermal conductivity material, by adding a certain percentage of the heating material, and under the heat of the metal liquid, the oxidant provides oxygen to oxidize the reducing agent and prolong the solidification time of the metal liquid in the riser.

3.In the case of different insulation covering agent, the mouth shrinks into a "dish-shaped flat or hemispherical bottom, which is shaped like a U-shaped throat.
