Description
one, technical field
The present invention relates to the end inserts formula electrode melting stove (all-electric melting or local electric smelting) electrode and to weigh warm cooling protection to electrical conductor in ultrahigh-temperature working order (more than 1600 DEG C temperature); the monomer equipment of many production technique and the production safety problems such as association electrical conductor resistance value, electrode thermal power, melt current density, electric smelter production efficiency, the device service time limit, quality product, especially ultrahigh-temperature resistance heat heated parts and electrical conductor workpiece charging operation and the long-acting cooling technology of system equipment.
two, background technology
Aerobic naked flame burning is the heat power engineering continued to use for a long time of human society and mode, 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, environmental safety key link is formed and has a strong impact on.By driving and the scientific and technical innovation effect of modern science, first electrode melting method is applied at glass industry and promotes.The novel preparation technology of glass industry, other non-metallic material and metal material field and equipment technology are become at present.
Electrode melting technology application electrode resistance self-heating high-temp principle completes the melting of melt, under utilizing non-metal material high temperature molten state, there is semi-conductor and conductor performance and metallic substance in the molten state, resistance value increases characteristic, and the conduction realizing melted material produces resistance heat and melts production.Modern electric smelter, adopt low-voltage and high-current Technology and three-phase alternating current single-phase electrode loop technology, not only electrode work produces ultrahigh-temperature state, also makes melt increase current density when liquid state, produce high-temperature electric thermal resistance, there is higher burn-off rate and production efficiency.Especially electric smelting work is without the need to helping oxygen.By electromagnetic field constraint effect and non-metallic material melting viscous effect, be melted material volatilization and greatly reduce, greatly improve environmental protection grade and environmental index.Become the important technology of preparing of modern fusing thermal technology.
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 of current whole world glass industry and nonmetal fusing equipment, first-selected molybdenum and molybdenum base alloy are as electrode.Because molybdenum and molybdenum base alloy possess outside above-mentioned performance, good electric current output density under also there is the fusing point (2630 DEG C) of superelevation and high temperature.
But the fatal defects that molybdenum electrode exists is low-temperature oxidation to be decomposed, and molybdenum, in 370 ~ 600 DEG C of temperature, is oxidized to molybdic oxide, in powder state material.Cause fracture and the hole of electrode, cause strength degradation and conductivity to reduce.Affect by this, especially by 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 for 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 be difficult to ensure.
The invention of electrode melting stove has the history of decades so far, and the thermodynamic material of electric smelter, builds peace standard, electrical control, and fusing system is very ripe and reliable.But by the equipment standard that electrode implantation mode specifies, there is larger production capacity and benefit difference at present.There is equipment simultaneously and extend the huge energy of application and environmental protection effect, formula electrode melting stove and accessory is inserted at the end outstanding equipment excellent properties and conglomerate, multi-field extension application advantage.Through scientific research with facts have proved, electric smelter electrode standard (electrode implantation mode) is to productive rate usefulness, watt consumption, the equipment cost of electric smelter, and quality product, productivity effect has obvious difference.The end, inserts formula electrode melting stove and inserts formula electrode melting stove and accessory than top-insertion type and Side and have outstanding advantage.From social demand at present and from now on and environmental protection requirement actual state; anaerobic melting and oxygen deprivation cracking technology of preparing, become the important technology trend and the equipment approach that are harmful to slag thing and flying dust thing after refuse, High water cut danger compound and burn processing are abandoned in modern society's process noxious industry.Therefore the distinctive equipment standard of formula electrode melting stove and steric requirements are inserted, the combination condition of multiple types thermal technology in the end, have application extension and the growth requirement in inter-trade and field.
The greatest problem that formula electrode melting stove exists is inserted at the end, is that electrode is changed.Electric smelter (being generally more than the vitreous state material 100 ton per day) electrode of larger production capacity does not allow to change in overhaul time, and therefore, the end of larger production capacity inserts formula electrode melting stove and is restricted at present.Be difficult to promotion and application.
The performance of formula electrode melting stove excellence and the situation of reality are inserted in the end, and key is the replacing of electrode, and key problem is cooling technology and the equipment technology of electrode.Because molybdenum electrode has good corrosion-and high-temp-resistant performance.Under non-cryogenic oxidizing condition, there is permanent working life.But cooling equipment and technology can not be ensured, adopt existing cooling of electrode mode and equipment technology, be difficult to realize the use safety that formula electrode melting stove is inserted at the end.
Formula electrode melting stove cooling technology basic structure is inserted at the existing domestic and international end and technical characteristic mainly contains two kinds of modes:

Another kind is the cooling of cylindrical shell ponding method.Adopt cylindrical shell sealing electrical conductor and Electrode connection.Water inlet pipe is placed in electrical conductor side, water shoot is placed in certain altitude in cylindrical shell, form the water surface of certain altitude, water inlet pipe to be penetrated the junction of spray and spoil over electrode and electrical conductor, but because electrical conductor is placed in body centre, water inlet pipe side is sprayed and is intercepted by electrical conductor, forms covering of the fan angle, cannot cool whole bonding surface, cool by cylindrical shell ponding.This mode cooler construction is simple, but electrode high temperature heat by conduction part cannot balance cooling, water coolant is caused to touch surface temperature lower, water cannot be touched in fan-shaped angle face and temperature is too high, 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 to melt, there is vaporization in cylindrical shell, interior pressure increases, and water inlet is obstructed simultaneously, and water cooler is melted or explosion failure.
Also the research and Experimental report that utilize other heat-eliminating medium is had both at home and abroad, but because of the limitation of preparation technology and technology, the case do not applied at present and run.
The cooling technology of formula electrode is inserted at the end, be now till insert the concentrated assembly place that formula electrode melting stove goes wrong in production practice at the bottom of many cases.Also be insert formula electrode melting stove equipment the end to use the Key technique problem faced.
