Description
Technical field
The present invention relates to a kind of firing equipment and method of cast welding irony die, especially relate to a kind of firing equipment and method of lead accumulator cast welding irony die.
Background technology
The lead accumulator cast welding is to adopt die (base material is magnesium iron or steel) cast welding basically, its heating process is required be, fast: heated up 150～200 ℃ in 1～2 minute; Accurately: temperature-controlled precision is controlled in ± 2.5 ℃; Efficiently: heating the frequency continuously is Mei Xiao Time 20～30 times; Safety: the thermal radiation protection of working temperature 400～500 degree; Environmental protection: environmental pollution is few.
At present, cast-weldmould firing equipment and mode that the lead accumulator industry is used as shown in Figure 1, adopt the resistance-type heating, at first will place the plumbous heating and melting of opened type lead melting furnace 3, the cast welding die body 1 that will be provided with die cavity 2 again is immersed in the fused solution lead 5 by lifting linking member 3, is heated to 450～550 ℃, then by lifting linking member 3 cast welding die body 1 level is proposed, die face is scraped with flat scraper, locate matched moulds with treating the cast welding part again, molding separates after the condensation, and (referring to accompanying drawing 1) finished in cast welding.In order to immerse 1～3 secondary mold, the alloying furnace volume is 300～3000 kilograms, and only about 0.3 kilogram of cast welding part in the mould, and both differ 3～4 orders of magnitude, and the plumbous liquid temperature of alloy is at 550～500 ℃ of section operations, and electricity-thermal conversion efficiency is only about 50%, causes the energy consumption height; The resistance-type heating belongs to external heating mode, owing to have thermal resistance and thermal inertia, is difficult to accuracy of temperature control control in ± 2.5 ℃; Resistance-type heating power density is about 12w/ square centimeter only, and mould is heated up 200 ℃, is difficult to accomplish; The thermal radiation of resistance-type heating is strong, and easily electric leakage, short circuit made and the maintenance cost height; In addition, the heating of traditional resistor formula and opened type molten lead also exist thermal radiation, heat-conducting medium (fusion of lead) secondary pollution etc., and the present environmental protection investments of lead accumulator account for 10～15% of gross investment.
Summary of the invention
This invention is Yaoed the technical problem that Solution determines and is: at the deficiency that prior art exists, provide a kind of both fast, accurately, efficient, safety, environmental protection, cast welding irony die firing equipment and method that energy consumption is low again.
The technical scheme that its technical problem of determining Solution of the present invention adopts is:
The present invention's cast welding irony die firing equipment comprises the radio-frequency induction coil that can produce 20～40khz high-frequency induction magnetic line of force, and described radio-frequency induction coil is installed on the base for supporting, and described radio-frequency induction coil links to each other with switch board by lead.
The present invention's cast welding irony die heating means are, cast welding irony die die body is directly placed the radio-frequency induction coil top that can produce 20～40khz high-frequency induction magnet-wire, and the distance of cast welding irony die die body and radio-frequency induction coil is 5 millimeters～20 millimeters; Adjusting reactance value is 0.5～1.5 microhenry, by the operation of switch board control radio-frequency induction coil, make the high frequency magnetic line of force that radio-frequency induction coil produces by cast welding irony die die body, make cast welding irony die die body 150～200 ℃ of high speed heating ups voluntarily in 1～2 minute.
Studies show that the power density of electromagnetic type heating wants high 3～5 times than resistance-type heating power density, can in 1～2 minute, cast welding irony die be heated up 150～200 ℃.
The electromagnetic type heating does not have heat-conducting medium, the mold very light weight, so its thermal resistance and thermal inertia are very little, its accuracy of temperature control can guarantee that control in ± 1 ℃ of scope, can reach the accurate temperature controlling requirement of cast welding fully, improves the cast welding quality.
The electromagnetic type heating, electricity-thermal conversion efficiency can than the resistance-type heating, can economize on electricity more than 30% up to 96%.
Because the electromagnetic type heating is interior heating, directly acts on die cavity, it is tangible that other parts of equipment can be improved to human body, solenoid adopts high pressure resistant high-temperature cable coiling, and good insulation preformance need not directly to contact with die body, exhausted nothing electric leakage, short trouble, safe and reliable.
Mode of heating of the present invention both can be used for the heating of lead accumulator industry cast welding die, also can be used for the heating of aspects such as the granulation of lead accumulator industry casting ball, casting sheet, was the desirable mode of heating of lead accumulator industry.
