two, background technology
Aerobic naked flame burning is heat power engineering and the mode that human society is continued to use for a long time, and along with the high speed development of modern industry, deficiency and the drawback of traditional thermal technology's mode manifest, and in production efficiency, in environmental safety key link, forms and has a strong impact on.Be subject to driving and the scientific and technical innovation effect of modern science, first electrode melting method is applied and promotes at glass industry.Glass industry, other non-metallic material and metal material field novel preparation technology and equipment technology have been become at present.
Electrode melting technology application electrode resistance self-heating high-temp principle completes the melting of melt, utilize under non-metal material high temperature molten state, there is semi-conductor and conductor performance and metallic substance under molten state, resistance value increases characteristic, and the conduction that realizes melted material has a resistance heat and melts production.Modern electric smelter, adopt low-voltage and high-current Technology and three-phase alternating current single-phase electrode circulation technology, not only electrode work produces ultrahigh-temperature state, also makes melt when liquid state, increase current density, produce high-temperature electric thermal resistance, there is higher burn-off rate and production efficiency.Especially electric smelting work is without helping oxygen.Be subject to electromagnetic field constraint effect and non-metallic material melting viscous effect, be melted material volatilization and greatly reduce, improved greatly environmental protection grade and environmental index.Become modern fusing thermal technology's important technology of preparing.
Electrode is the core workpiece in electric smelter equipment.Electrode materials not only will have higher high-temperature capability, will have good perveance simultaneously, the resistance stabilization performance under the condition of high temperature, superpower corrosion resistance nature.The electric smelter that whole world glass industry and nonmetal fusing are equipped at present, first-selected molybdenum and molybdenum base alloy are as electrode.Because molybdenum and molybdenum base alloy possess outside above-mentioned performance, also there is good electric current output density under the fusing point (2630 ℃) of superelevation and high temperature.
But the fatal shortcoming that molybdenum electrode exists is low-temperature oxidation decomposes, and molybdenum, in 370 ~ 600 ℃ of temperature, is oxidized to molybdic oxide, is powder state material.Cause fracture and the hole of electrode, cause strength degradation and conductivity to reduce.Affected by this, be especially subject to the constraint of existing cooling technology, up to the present, the standard of electrode electric melting furnace, is difficult to change decades.It is main continuing to use top-insertion type electrode always, and side-plug-in electrode standard is auxiliary equipment standard.Major cause be electrode after damage, can change and cooling technology is difficult to guarantee.
The invention of electrode melting stove is the history of existing decades so far, and the thermodynamic material of electric smelter, builds peace standard, electrical control, and fusing system is very ripe and reliable.But be subject to the equipment standard of electrode implantation mode regulation, have at present larger production capacity and benefit difference.Exist equipment to extend the application huge energy and environmental protection effect, formula electrode melting stove and accessory is inserted at the end has outstanding equipment excellent properties and conglomerate, multi-field extension application advantage simultaneously.Through scientific research with facts have proved, electric smelter electrode standard (electrode implantation mode) is to the productive rate usefulness of electric smelter, watt consumption, equipment cost, quality product, and productivity effect has obvious difference.Formula electrode melting stove is inserted at the end has outstanding advantage than top-insertion type and the slotting formula electrode melting stove and accessory of Side.From social demand and environmental protection requirement actual state at present and from now on; anaerobic melting and oxygen deprivation cracking technology of preparing, become modern society and processed important technology trend and the equipment approach that harmful slag thing and flying dust thing after refuse, high moisture danger compound and burn processing are abandoned in noxious industry.Therefore the distinctive equipment standard of formula electrode melting stove and steric requirements are inserted in the end, and multiple types thermal technology's combination condition has inter-trade and application extension and growth requirement field.

A kind of is that tubular type spill-over method is cooling.Be that electrode and electrical conductor connecting portion are placed in the metal cylinder of sealing, water coolant in overflow status, solves being heated of electrical conductor and resistance change with this at cylindrical shell.This mode requires into drainage speed very fast, produces a large amount of heat energy loss, and overall power consumption is larger.Once meet, add melting materials capable larger, while reducing electrode temperature, or power supply system interruption, in electrode inactivity situation, easily cause electrode low-temperature oxidation.Electrode is attenuated or decompose hole, when serious, fracture has an accident.
Another kind is that cylindrical shell ponding method is cooling.Adopt cylindrical shell sealing electrical conductor to be connected with electrode.Water inlet pipe is placed in electrical conductor one side, water shoot is placed in certain altitude in cylindrical shell, form the water surface of certain altitude, to penetrate the junction of spray and spoil over electrode and electrical conductor on water inlet pipe, but because electrical conductor is placed in cylindrical shell center, water inlet pipe side is sprayed and intercepted by electrical conductor, forms covering of the fan angle, cannot be cooling to whole bonding surfaces, cooling by cylindrical shell ponding.This mode cooler construction is simple, but electrode high temperature heat by conduction part is cannot balance cooling, cause water coolant to touch surface temperature lower, fan-shaped angle face cannot touch water and excess Temperature, produce larger resistance value, under the liquid conduction state of melt, once liquid object touches cylindrical shell position in stove, form conductive effect.Cause cylindrical shell fusing, have vaporization in cylindrical shell simultaneously, interior pressure increases, and water inlet is obstructed, and makes water cooler fusing or explosion failure.
Also there are both at home and abroad the research and the experiment report that utilize other heat-eliminating medium, but because of the limitation of preparation technology and technology, the case that there is no application at present and move.
The cooling technology of formula electrode is inserted at the end, is to insert the concentrated assembly place that formula electrode melting stove goes wrong in production practice at the bottom of many cases till now.Also be to insert formula electrode melting stove equipment the end to use the Key technique problem facing.
