How to choose high quality graphite block?There are several methods that can help you.
1、Under high speed or high pressure, it is necessary to use effective methods to dissipate the friction heat, which should be cleaned when it is used in the medium with crystal precipitation.
2. The differences of thermal expansion coefficient should be paid attention to the carbon graphite ring or bearing which are inlaid with metal parts. Assembly, the choice of excessive amount should be reasonable, not too large.
3. Before installation, two working surfaces of friction pair must be grinded. After installation, the friction pair runs firstly at low speed or starts to work in the working state repeatedly through running-in, which can be put into operation.
4. Carbon— graphite is a kind of brittle materials. Generally speaking, its mechanical strength is lower than metals. Therefore, we should be fully aware of this during the designing of the structure and be careful in the process of machining and assembly operations, it is forbidden to beat with rigid thing to avoid cracking.
Our company bring in various manufacturing technology, producing all kinds of products in different fields continuously after conversion, absorption, and combined with XRD Graphite own advantages. Our graphite blocks strengthen technical advantages continuously. It is mainly used in nuclear industry at present.
