Abstract
The utility model discloses a high-temperature carbonization furnace for the large-scale production of carbon fibers. According to the high-temperature carbonization furnace, the heating temperature is 1,000-1,600 DEG C. The structure of the ultra-high-temperature rectangular furnace is as follows: a graphite muffle furnace hearth is divided into two portions, namely a temperature homogenizing zone and a heating zone, and heating devices are arranged on the upper and lower faces of the furnace hearth and are formed in a manner that graphite heating elements and graphite electrodes are in threaded connection. A large number of hard graphite felt is arranged in a furnace body and serves as a heat preservation system, an outer layer of the heat preservation system is of a steel-structured furnace shell, and a detachable water cooling plate is stuck to the outer face of the furnace shell. Voltage instability caused by the fact that the heating resistance and graphitization resistance become higher due to the oxidization and cross-sectional surface ageing of the graphite heating elements is counteracted by using tapped transformers.

In carbon fiber production process, high temperature cabonization equipment is extremely crucial.Carbide furnace is high because have operating temperature, and is large to the performance impact of carbon fiber, and comprehensive technical level requires high, becomes the key equipment in the large-scale production line.Because the carbon-fiber high-temperature carbonizing apparatus is started late in China, the license granting mechanisms of developed country to China's high temperature cabonization equipment.It is the bottleneck that restricts China's carbon fiber industry development.
The carbon current procedure of fibre production is with in high temperature carbonization furnace, and the heating original paper is Elema or Si-Mo rod, and burner hearth is carborundum or corundum material, and insulation material is aluminium silicate wool, and furnace shell is the individual layer carbon steel.Maximum operation (service) temperature is no more than that 1400 ℃, type of furnace heat-insulating property are poor, the body of heater poor air-tightness, and the burner hearth life-span is short, can not satisfy to prepare the more demand of high modulus carbon fiber.
Summary of the invention
The invention reside in and overcome present technical deficiency, and a kind of high temperature carbonization furnace of large-scale production carbon fiber is provided, can satisfy the needs that the scale carbon fiber is produced.
The problem to be solved in the present invention is to realize by following technical scheme: a kind of high temperature carbonization furnace of large-scale production carbon fiber, heating work temperature are 1000 ℃-1600 ℃; The structure of high temperature carbonization furnace is the graphite muffle thorax, and burner hearth is that the graphite cake by 50-80mm divides the multistage overlap joint to form; Burner hearth divides 2-7 warm area, and temperature is with the warm area step increase, and each warm area is separated as thermal insulative board by the hard felt of graphite; The burner hearth upper and lower faces all has heater, and heater is to be threaded by graphite heating component and graphite electrode to form.In the body of heater of high temperature carbonization furnace, by forming heat-insulation system by materials such as the hard felts of graphite, the skin of heat-insulation system is the furnace shell of steel construction, posts dismountable cold water plate outside furnace shell.High temperature carbonization furnace is furnished with the transformer with tap, is used for offsetting the heating graphite element and becomes large due to the aging heating resistor that causes of the carrying out of oxidation and transverse section surface and the graphite resistance becomes the variation that causes greatly voltage.The heater of high temperature carbonization furnace is comprised of by the screw thread stressed joint graphite heating rod and heating electrode; Graphite heating rod and heating electrode are that resistivity is at 20 Ω μ m or the graphite products more than 20 Ω μ m.The body of heater of high temperature carbonization furnace is interior by the heat-insulation system that is comprised of the hard felt of graphite; The hard felt of graphite between 200-400mm forms insulation material by thickness.The body of heater shell of high temperature carbonization furnace is the thick steel structure casing of 5-10mm, and housing posts dismountable cold water plate outward.The 2-7 of high temperature carbonization furnace all adopts a thermal treatment zone transformer with tap.
Beneficial effect of the present invention: can satisfy the demand of large-scale production high-performance carbon fibre, break technology and the corner on the market of developed country to high temperature cabonization equipment, drive the fast development of domestic carbon fiber equipment, technology.Compare with conventional art, for the large-scale production high-performance carbon fibre provides the high temperature cabonization equipment that performance safety is reliable, the intensification temperature is high, the life-span is long.
