“Why is the graphite boat hollowed out?” Generally speaking, what shape the graphite product is based on the purpose. The following are the uses of the graphite boats. The purpose determines the hollowing effect of the graphite boat:
Graphite boats are graphite molds (graphite boats are graphite crucibles, used to cast gold bars, silver ingots, etc.). The graphite mold is a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering. The graphite mold is made of artificial graphite by mechanical processing. Therefore, graphite molds are sometimes graphite boats
Graphite boat has the characteristics of oxidation resistance, high density, oxidation resistance, thermal conductivity and stability. It is a sintered material box used to fire lithium battery materials, which is beneficial to ensure the quality of the battery.
Graphite boat is a new type of special material for the production of high-energy density primary batteries. It is also a material with high energy density, high stability, and high utilization rate obtained by the battery industry so far.
Graphite boat is a new type of special material for the production of high-energy density primary batteries, and it is also a material with high energy density, high stability and high utilization rate obtained by the battery industry so far. Its usage is as follows:
1. Vertical and stable
The sagger column in the outer ring should not be inclined to the kiln wall, but it can be slightly inclined to the center of the kiln. And between the saggar columns, please use fire-resistant clips to support each other to prevent them from crooking at high temperatures.
2. After filling the kiln, close the kiln door
1. Please apply refractory clay on both the inner and outer layers of the refractory brickwork. The outer layer should be flush with the outer wall of the kiln wall, and the inner layer should be flush with the inner wall of the kiln wall.
2. When building the kiln, please set aside a fire observation hole. The position of the fire observation hole should be fixed every time the kiln is installed, so as to avoid the phenomenon of high and low, large and small, which will affect the correct temperature measurement.
Third, the height of the sagger column
Please decide according to the temperature rise of various parts in the kiln and the structure of the kiln. Generally speaking, although the middle sagger column can be adjusted higher, it should also be left empty with the top of the kiln, so that the rising flame will converge here, and then redistribute it to the fire channels of the fire absorbing holes. In order to reduce the resistance of the flame to rise, the graphite boat column near the vent should be lowered a bit.
