1.Lift the installed pneumatic vibrator into the forma, put it in the bottom, and then raise it by 50mm. Adjust the distance between the hammer head and the forma. With 30mm as the standard, ensure that the hammer head can effectively contact the inner lining of forma.
2.Turn on the gas valve for 30 seconds at low speed, then vibrate at full speed, and vibrate for 5 to 8 minutes for each 100mm increase until 300mm below the top of the furnace.
3. Furnace Heating Technique of Former Patching Lining
3a) Fully fill small and dense scrap materials into the furnace, and heat up at 100-200 celsius degree per hour.
3b) During melting, raise powers slowly to ensure crucible not break until it is full.
3c) Keep heat preservation for one hour at 1680-1700 celsius degree, detecting temperature once per 20 minutes.
3d) After sintering finished inside furnace, it can start to work.

Application of Ladle Castables
Application of 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)

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.
