Abstract
The utility model discloses a composition electric resistance furnace made of heat supplying treatment metallic material. In the composition electric resistance furnace, composition heaters are adopted to replace the original resistance wires which are placed on the partition bricks built on the furnace wall; a composition heating system is composed of more than three heaters; the resistance wires with different specifications are placed in the heating plate holes with different specifications to form the heaters, and the heaters are fixed on the inner wall of the box body. By utilizing the heaters, the resistance wires can not expose in the box body, and the equipment failure and personal injury caused by accidents can be avoided; the service life of the composition electric resistance furnace can be extended thereby; meanwhile, the time of the installation and maintenance is shortened, the working condition of workers can be improved, and the energy can be saved.
Description
The utility model belongs to the improvement of metallurgical Equipment for Heating Processing, is used for the combined type resistance stove of heat-treated metal material.Resistance furnace is by formations such as casing, furnace wall, gim peg, electric furnace heating wire, drop-bottoms.
Existing cabinet-type electric furnace is that the fifties continues into the present, and is generally three phase mains.It has casing, electric furnace heating wire, refractory brick interlayer, both sides and bottom distribution electric furnace heating wire in the furnace wall.Electric furnace heating wire exposes in stove very dangerous; If the shove charge workpiece does not notice that easy and stove silk is collided, and causes equipment and personal injury.Because electric furnace heating wire exposes in the stove inboard, directly contact with air, oxidation especially easily during high temperature is so service life is shorter.Maintenance inconvenience and repair cycle are long, the maintenance Large Furnace period of the day from 11 p.m. to 1 a.m, and the people will get in the high temperature furnace hall, the repairing of bending over; Small-sized electric furnace is repaired, and the people bores not enter, and repairing is just more difficult, and electric furnace heating wire is had no progeny whole dismounting once, needs all left and right sides time.Existing cabinet-type electric furnace is built into by refractory brick, falls into the stove hall with a period of time seat clay, influences workpiece and stove hall health.Because the thick caloric receptivity of furnace wall is big, the idle work of doing is many, so energy waste is serious simultaneously.
The purpose of this utility model is in order to overcome the problem that prior art exists, resistance wire not to be exposed in casing, avoid causing equipment and personal injury, prolonging the service life of resistance furnace; For the ease of installing and maintenance, shorten and install and maintenance time simultaneously, improve workman's working condition, energy savings, and design a kind of combined type resistance stove that constitutes by combination heater.
Design of the present utility model: adopt combination heater to replace the resistance wire of the laying heating that is built on the original furnace wall on brick, the combined heated system is made up of the heater more than three.
The utility model is made up of casing (1), furnace wall (2), gim peg (3), resistance wire (4), heating plate (5), drop-bottom (6).Casing is to make with the A3 steel plate; Furnace wall is built into common refractory brick, seat clay; Gim peg is the heat resisting steel bolt, is used for fixing heater; Resistance wire is a heating element heater; Heating plate is that proprietary material is made, and design respectively according to the watt level of stove; Drop-bottom is to cast with heat resisting steel.
Casing of the present utility model adopts the cabinet-type electric furnace shell of present domestic production, and the casing inner furnace wall is built into refractory brick.Then resistance wire is chosen size by power demand, be rolled into the spiral electric furnace wire ring of certain diameter, spacing, again the electric furnace heating wire of spooling is placed in the special heating plate hole, form heater, far ultrared paint is coated in the inboard of heating plate, at last mounted heater is fixed on the cabinet wall, and every side is made up of an above heater, connect three phase mains, just reach the purpose of heating.When various power models did not wait, the size of heater, size were also different, but operation principle is the same.
The utility model can be formed by three heater combinations, one of bottom, each one of both sides.
The utility model compared with prior art, installation and maintenance are convenient especially, the people need not get in the stove and lay bricks, adorns resistance wire during installation, only need replace wherein broken parts during maintenance.Shortened installation period greatly, both safe and reliable, energy savings has again prolonged service life of electric furnace simultaneously.
Accompanying drawing 1 is the profile of combined type resistance stove: 1-casing, 2-furnace wall, 3-gim peg, 4-resistance wire, 5-heating plate, 6-drop-bottom
Casing (1) is the shell that adopts the chamber type electric resistance furnace of present domestic production, and appearance and size is example with H-60 molding box formula electric furnace, high 1500mm, and wide 1600mm, dark 2000mm, casing adopt the thick A3 steel plate of 3mm to make, and add reinforcement.The main application of casing is to support the weight of whole stove, and the material of whole stove is installed; Furnace wall (2) thickness is 400mm, is built at cabinet wall with common refractory brick, seat clay, in order to heat-insulation and heat-preservation; On furnace wall, casing, stay the hole of three diameter 25mm, in order to fixing heating plate.Heating plate (5) is that proprietary material is made, appearance and size: thick 80mm, and long 1600mm, wide 500mm, the hole of 8 the diameter 35mm that distribute above, thick by the hole wall in the stove is 10mm, thick by furnace wall place hole wall is 35mm.Heating plate does not expose the heating plate end face in the time of will considering the electric furnace heating wire turnback when design, to guarantee safety.Coat far ultrared paint penetrates to increase heat energy width of cloth in stove in the inboard of heating plate.Resistance wire (4) is a heating element heater, with the resistance wire coiled spacing 20mm of the Cr20Ni80 of diameter 5mm, the spiral coil of external diameter diameter 30mm, it is through in the heating plate hole, is combined into heater, two statures stretch out heating plate one end, draw connector lug, be fixed on the casing, meet electric 380V.The heater that resistance wire and heating plate are combined into is fixed on the both sides and the bottom of furnace wall and casing with three heaters by gim peg, and every side is with the heat resisting steel bolt (3) of three diameter 20mm.At last drop-bottom (6) is placed in bottom half, i.e. successful installation.Drop-bottom is to cast with heat resisting steel, is of a size of long 1600mm, wide 750mm, and thick 40mm is in order to stack heat treated part.
Claims (2)
1, a kind of combined type resistance stove is made of casing (1), furnace wall (2), gim peg (3), electric furnace heating wire (4), heating plate (5), drop-bottom (6), it is characterized in that heater is made up of heating plate (5) and resistance wire (4), and be fixed on the cabinet wall by the heater more than three.
2, resistance furnace according to claim 1 is characterized in that being fixed on by above-mentioned three heaters the both sides and the bottom of casing.
