The influence of the storage environment of the graphite crucible on its function is cumulative, and the impact is very large, which generally requires the existence of a clean and monotonous waterless environment and the aluminum graphite crucible is supported on a fixed wooden frame. Transportation problems, although graphite crucible has a good high temperature resistance function, but it is a very simple crushed product, in the process of application and transportation, special attention should be paid to the production can not be severely damaged. The meaning of the existence of the mall is not very high, in fact, I think it is very wrong.
The graphite crucible seems to be a very simple structure, which is used to hold various liquids, but the lack of it in metallurgical operations will cause great problems, in addition to metallurgical operations and even chemical operations, there are many local applications for it.
The versatility of graphite crucibles is its benefit. The main raw materials on the edge of the graphite crucible are graphite and quartz stone, which are then mixed with many other chemical liquids and fired. Crucibles can accept strong acids, bases, and other corrosive liquids, which are useful in chemical applications. After examination by scientists, it was found that aqua regia can also be used in graphite crucibles. In addition, it has the effect of high temperature resistance. High temperatures above 5000 degrees have little effect on it. There is no problem with storing molten iron or aluminium after ablation with a graphite crucible. The quality of the graphite crucible is another of its great benefits.
The pressure on the graphite crucible from the outside world is so great that it can hardly be held hostage to it, unless the strength exceeds what it can accept, as long as it is not artificially damaged. The production process of each graphite crucible is very detailed, and every link and every process is very clear, as long as the product is qualified. After the production of each graphite crucible is completed, the quality inspection will be carried out, and the detection will be sold to customers. The relevant parts will also inspect the products together, and if they find that the unqualified situation will make the enterprise produce one after another, and even pay a huge fine to close the factory.
The reason why it is so severe is because the liquid graphite crucible is harmful to the human body, and once it leaks, it is likely to have a severe impact on people's health, so it is necessary to grasp it from the source to prevent similar situations from occurring.
(1) Equipment gas or oil furnace crucible: place the crucible on the base, reserve a certain crucible expansion space at the top of the graphite crucible and the furnace wall, and fix it with wooden blocks, cardboard and other materials. Adjust the burner and nozzle orientation so that the flame is aimed at the combustion chamber and not directly at the bottom of the graphite crucible.
(2) Crucible for equipment converter: The crucible is fixed with support bricks at both ends of the crucible mouth to prevent the crucible from being stuck. Put cardboard and other materials of about 3-4mm together with the support brick and crucible cushion block as a large space for crucible pre-expansion. Graphite crucible equipment resistance furnace crucible: The crucible should be placed in the center of the resistance furnace, and the bottom of the crucible should be higher than the bottom row of the heating element. Seal between the top of the graphite crucible and the edge of the furnace with insulation cotton.
(3) Crucible for induction furnace: ensure that the graphite crucible is placed in the center of the induction coil to prevent the crucible from overheating and cracking.
