Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is described further, in order to be better understood from technical solutions of the utility model.

Embodiment 1: a kind of Baking profile formulates stove, referring to Fig. 1, including body of heater, it is filled with insulation material as heat-insulation layer 2 in the interlayer of described body of heater end face furnace wall, body of heater left and right side and bottom surface are respectively arranged with graphite cake 3, graphite cake thickness is 18��22mm, and is filled with inserts respectively between graphite cake 3 and body of heater left and right side and bottom surface inwall as packed layer 6, and packed layer thickness is 0��6mm. Graphite cake arranged outside in body of heater left and right side has quirk 4, is filled with rock wool formula insulation material as rock wool formula heat-insulation layer 5 outside quirk 4 in the interlayer of furnace wall, and rock wool formula insulation layer thickness is 140��150mm. There are natural gas line 7 and capstan 11 respectively with quirk inner space in body of heater left and right side, natural gas line 7 is provided with adjustment valve 8, regulate valve 8 to be used for regulating natural gas consumption, be provided with thermocouple 9 at fire channel place, body of heater left and right side, described thermocouple 9 is electrically connected with thermometer 10. It is respectively mounted quartz plate as perspective plane in the forward and backward face of body of heater. Quartz material, has high-temperature stability (more than 1750 DEG C) and also transparent, quartz plate thickness: 20��30mm.The change in stove of the Baking profile temperature-rise period goods is can be clearly seen that, thus a set of Baking profile being suitable for this based article can be set out by forward and backward perspective plane. Test specimen dead size in the present embodiment: 400(length) * 350(height) * 400(width) mm, and furnace length: 960mm width: 400mm height: 600mm.

The longer the better for roasting heating curve in theory, and two is middle slow soon, and early stage heats up and wants fast, and the Colophonium in product will not migrate, and heating up and want slow in centre, make the eliminating slowly of the fugitive constituent within goods, and this stage is most important. Being exactly the coking stage after fugitive constituent is drained, this stage articles is shaped substantially, can be hurry up so heating up. But fact proved that the roasting heating curve setting an applicable product could effectively ensure the yield rate of roasting. Because the raw material of every kind of carbon product is different, production technology is different, molding mode, goods bulk density etc. different, make article characteristic there occurs delicate change, cause that the goods several stages (softening stress-displacement stage, volatilization period, coking stage) in roasting process also can different change. So it is particularly important for testing out a set of rational Baking profile according to the characteristic etc. of product, also it is related to the destiny of this enterprise simultaneously. Example: certain carbon element factory's roasting �� 800*2000 graphite electrode, 5 rooms of a stove, 2 layers can be filled up and down, every layer can fill 10 electrodes, and a stove fills 100 electrodes altogether. After goods roasting is come out of the stove, yield rate is 0, whole waste products. Post analysis reason, because of Baking profile set unreasonable causing all ftracture when goods are calcined, these stove goods direct losses nearly million yuan, if setting out a set of rational roasting heating curve by experiment, it is possible to avoid this tragedy. Thus, the Baking profile of the present embodiment formulates stove exclusively for formulating the design of a set of rational roasting heating curve, can intuitively, clear, reflect the actual Baking profile of product accurately, then pass through experiment and can formulate out the roasting heating curve being suitable for this product. Improve yield rate and the roasting quality of baked article.
