Description
Technical field
The utility model relates to a kind of metal casting equipment, specifically is a kind of die casting electric smelter.
Background technology
Smelting furnace for pressure casting is mounted in the indispensable equipment that is used for melting materials capable on the die casting machine, and the modes of oil (gas) burning that adopt add thermal material more.Although the no chimney stove that patented last year can be fuel-efficient more than 30%, because Middle East situation is still in a mess, oil price has now risen to 80 dollars every barrel of crude oil, mad the rising to more than 100 dollars of having an opportunity.So the electrically heated energy-efficient Smelting furnace for pressure casting of a kind of on-fuel usefulness of necessary development, voltage supply casting client uses.
As for using electrically heated Smelting furnace for pressure casting, two kinds of designs are arranged both at home and abroad at present.The one, heating wire is loaded near the melt cylinder outside or is attached to the furnace shell inboard, and after the heating power, heat is passed to the melt cylinder by radiation.This mode has two shortcomings: 1. can make heating wire burn aglow (more than 1000 ℃) usually, heating wire blows easily; 2. the space is bigger because heating wire and heat transfer position account for, and thermal insulation layer is thinner, rapid heat dissipation, and loses heat is also bigger, so power consumption is big, and melting efficiency is low, wants 5 hours just melting metals usually after the energising.Another kind of mode is that heating wire is loaded in the melt cylinder, though such mode of heating melting efficiency is high, also has two shortcomings: when 1. adding whole piece kirsite material, do not notice slightly that the zinc material of kilogram weight more than 10 can impact and break heating wire; 2. the kirsite liquation is very fast to electrothermal tube corrosion in the cylinder, and after the pipe that 1～2mm is thick was corroded and wears, heating wire just was easy to blow.
Because oil (comprising gas) valency is more and more expensive, and the existence of old-fashioned electric furnace is conducted heat slowly, short-life shortcoming, is badly in need of a kind of efficient, energy-conservation electric heating Smelting furnace for pressure casting.
Summary of the invention
The purpose of this utility model provides a kind of melt and is heated evenly, and burn-off rate is fast, and the thermal efficiency is higher, melt cylinder and heating wire die casting electric smelter durable and that for ease of maintenaince change.
To achieve these goals, the technical scheme that the utility model adopted is as follows: a kind of die casting electric smelter, comprise that the bottom is equipped with the body of heater of runner, upper cover plate, is embedded in the melt cylinder of body of heater inside and is installed in the discharge gate of body of heater bottom, described melt cylinder external process live wire groove, the heating wire assembly is in wiring duct, body of heater at the middle and upper levels and the space between the melt cylinder be filled with fire-resistant cotton, the bottom of body of heater is to use the furnace bottom layer of fire-resistant brick dress, a side of body of heater is equipped with safety head.
Described melt cylinder is designed to elongated oval shape, is processed with a plane that is used to install heating wire in its both sides and bottom, and is processed with many semicircle wiring ducts in the plane.
Described heating wire assembly is in wiring duct inside, and its top is provided with press strip.
The lead of described electric smelter inside adopts delta connection to connect.
The utlity model has following advantage:
1. initiate specially designed melt cylinder, because hot cell machine melt cylinder is oblong, arc is all arranged at the bottom, two ends, heating wire be difficult for to be installed, therefore to be designed the melt cylinder more elongatedly, in both sides and the bottom design three Plane Installation positions especially, and in many semi-circular grooves of plan-position design, so that the traditional thread binding bank of the electric heating that matches is gone into groove, enlarge contact area as far as possible, to improve heat transfer rate.
2. because heating wire is close to the melt cylinder outside, so insulated space is big, and thermal insulation layer has been thickeied, and thermal loss is also little.
3. but body of heater both sides iron plate is adopted unfolding mode, changes if heating wire has been broken for ease of maintenaince, and furnace bottom has one deck refractory brick and discharge gate, in case the corrosion of melt cylinder has been worn, alloy material can flow out from discharge gate.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is schematic cross-sections of melt cylinder 3.
1. bodies of heater among the figure, 2. upper cover plate, 3. melt cylinder, 31. wiring ducts, 4. discharge gate, 5. heating wire, 6. furnace bottom layer, 7. fire-resistant cotton, 8. safety head, 9. runner.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Be an embodiment of the present utility model as shown in Figure 1, this die casting electric smelter mainly is made up of body of heater 1, upper cover plate 2, melt cylinder 3, discharge gate 4, heating wire 5.The bottom of body of heater 1 is equipped with runner 9, and melt cylinder 3 is embedded in the inside of body of heater 1, and discharge gate 4 is installed in the bottom of body of heater 1.Melt cylinder 3 is an elongated oval shape, is processed with 3 planes that are used to install heating wire 5 in its both sides and bottom, and is processed with many semicircle wiring ducts 31 in the plane.Heating wire 5 assemblies are in wiring duct 31, and press strip is pressed on heating wire 5 in the wiring duct.Body of heater 1 at the middle and upper levels and the space between the melt cylinder 3 adopt fire-resistant cotton 7 fillings full, the bottom of body of heater 1 is to use the furnace bottom layer 6 of fire-resistant brick dress, a side of body of heater 1 also is equipped with safety head 8.Body of heater 1 both sides adopt removable iron plate to process, so that the maintenance of heating wire or replacing.The lead of electric smelter inside adopts delta connection to connect.The concrete processing and making process of this electric smelter is as follows: use fire-resistant brick install furnace bottom layer 6 after, melt cylinder 3 is hung in 2 stove top case plates 2, after heating wire 5 assemblies being gone into the wiring duct 31 of melt cylinder 3, compress with press strip, then stove is expired whole spaces with fire-resistant cotton 7 fillings at the middle and upper levels, connect wires, cover and adorn 8 safety heads by delta connection then.After the normal power-up, the heating wire heating is directly conducted heat fast and is given the melt cylinder, and metal charge in the fusible cylinder.The multiple layer refractory cotton is heat insulation in the burner hearth, prevents that effectively heat scatters and disappears.
The utility model has been done following test on July 19th, 2006.One cooperates the dynamo-electric smelting furnace test in CG-88 hot cell, and the 300kg kirsite begins energising from 28 ℃ of room temperatures, only need whole fusions in 2 hours 47 minutes and be warming up to 420 ℃ can die casting state, improve more than 40% than old-fashioned radiant type electric furnace efficient, economize on electricity more than 50%.And heating wire is close to the melt cylinder, and the evolution of heat is absorbed by melt cylinder and alloy material at once, and heating wire can not burn to aglow, but with long-term work, easy burn-out not.
