1) The measuring temperature for graphitizing furnace was studied.

2) Based on these, making use of graphitizing expansion property to eliminate surface blowhole has been proposed and verified with tests.

3) The results show that high temperature graphitizing annealing can be carried out through altering the silicon content of the cast iron.

4) The graphitizing degree of two kinds of carbon slides obviously increased after high temperature heat treatment.

5) High temperature graphitizing annealing kinetics for high manganese malleable cast iron has been investigated.

6) The components, modification and graphitizing annealing technology of ductile cast iron as-cast was researched.

7) The influence of SG inoculant on graphitizing annealing of malleable cast iron was investigated.

8) All graphitizing elements decrease the metastable eutectic temperature, increase the stable eutectic temperature and enlarge their distance.

9) D-C graphitizing furnace has many advantages, particularly in the economy of power,(http:///graphitizing.html) when comparised to A-C graphitizing furnace.

10) D-C graphitizing furnace has many advantages, particularly in the economy of power, when comparised to a-c.graphitizing furnace.

11) The dependence of graphitizing degree of two kinds of petroleum cokes on temperature was studied.

12) Higher CE is helpful to improve the self-feeding ability of graphitizing expansion during solidification process, and to reduce casting defects, such as shrinkage and blowhole.

13) The temperature distribution has two peaks. The first peak is due to solidification shrinkage, and the second peak is related to the graphitizing expansion during solidification of cast iron pipe.

14) With the development of this research, the reality of auto controlling of the graphitizing resistance furnace and the best ascending temperature remaining in the furnace will be taken.

15) On the basis of lots of study on present graphitizing furnace, RBF neural network is put forward to model graphitizing furnace in order to make accurate control.

16) The tube wall is composed of graphite layer from efficient graphitizing process.

17) With the increase of the content of silicon, the high temperature graphitizing annealing time decreases.
