What can replace a graphite crucible?
Silicon carbide crucibles can be used instead of graphite crucibles.
Installation of crucible:1. The crucible base (crucible station) requires the same crucible bottom diameter or greater height of the crucible platform to prevent fire from spraying into the crater above the crucible.2. Using refractory bricks, the crucible station shall be a round brick, flat without bending, and shall not be made of brick or semi - uniformly, preferably imported graphite crucibles.3. The unit is placed in a crucible melting, melting of the solution in the center, the coke powder, made of ash or refractory cotton mat, in order to avoid the crucible and crucible Taiwan rod, erected after the crucible, need to melt and the need for the central level (highest level ruler).4. The size of the crucible and furnace fit, the distance between the crucible and the molten wall, shall be suitable for at least 40mm.5. When the furnace crucible is installed, the gap in the gap below the contact brick, the crucible should be set aside about 30-50MM dollars gap, not the bottom pad, things, mouth and smooth cotton, refractory material, furnace wall. Requires a fixed furnace wall, refractory bricks, thermal expansion, space heating after the required corrugated cardboard, 3mm thick pad crucible.
Save and process.1. Graphite crucible is afraid of water, and must avoid moisture and water flushing.2. Note that the surface is raised instead of placing the crucible directly on the floor and placed on the tray.3. Not rolling horizontally on the floor, when pushing pads, requires something softer, such as cardboard or cloth, so as not to bruise, scrape, and stand on the floor at the bottom.4. You can't land or crash while handling. Please pay special attention to it.
Graphite crucible special tips:1. Be careful not to let the mechanical outside hit, do not belong or strike from the top.2. Should not be exposed to water or stored in a dry place.3. Built in melt dry, without contact with water.4. In use, flames that are not directly in the crucible (jet to the bottom of the crucible) will have a marked black mark at the bottom of the crucible if it is sprayed.5. After the aluminum is stopped, the remaining copper material is tried without leaving residue in the crucible.6. Use the proper amount of oxide (slag, etc) to avoid erosion of the crucible. Excessive use may cause erosion and damage to the crucible.7. When placed in a crucible, there is no need to use mechanical power to have a significant impact.
