All previous space materials processing experiments in China since 1987 in the paper is summed, Schedule of flight main space materials processing furnaces in China is got, Prototypes of some type of telescience space processing furnaces have be developed in China near years, see table 2. Table 2 Prototypes of some type of telescience space processing furnaces have be developed in China near years number NamenameMoving These performance and character of three telescience furnaces are detailed in the paper. YK1 system is the "net distributing" structure connecting by cable composing by two each other absolute in physics computers: one operating by PI and another collecting data and controlling on space, both MODEM , processing furnace and experiment data collecting device. Computer operating by PI creates curves of temperature field in the furnace and sample and interface between solid and liquid moving on the basis of characteristic parameters receiving real time, to help PI user to estimate and decision-making, and by the computer real time send out teleoperational code, then changes experiment state of material processing furnace. YK2 in the basis of YK1 specifies the telescientific parameters acquisition technology for the material-processing furnace in space, the technology of AV and the remote control for the furnace. Based on the remote sensing data, the computersachieve the two-dimension and three-dimension cartoon for the isotherm and the solid-liquid interface of the material processing in the furnace. Based on the TCP/IP protocol, the PPP method and the PSTN, PI and experiment achieve the data exchange and PI realizes remote control for the experiment (to change heat power). Then YK3 realizes the teleoperation random replacing samples in the furnace by robot, during long time without space- crew.
