Description
The utility model relates to the metal material resistor furnace for heat treatment.
Resistance furnace is the bigger heating equipment of power consumption in the electronic product, also is the main firing equipment in the heat treatment step, is widely used in the metal material Technology for Heating Processing of mechanical metallurgy industry.All kinds of resistance furnace linings of domestic production at present.Mostly be traditional brickwork construction, mainly exist the interior heat-insulating property of body of heater poor, the thermal efficiency is low, easily heat radiation, and the furnace temperature heating-up time is longer, and body of heater is low service life, problems such as maintenance inconvenience.
It is big that the purpose of this utility model mainly solves the resistance furnace power consumption, heating-up time is long, the thermal efficiency is low, heat-insulating property is poor, problems such as equipment is heavy, and door opened effort sealing is bad, utility model is on design and manufacturing process, changed structure, material and the process of former resistance furnace, specifically improved as follows:
Lining Design has changed the structure of traditional brick furnace lining, material, process, the optimizing application design, science selection, advanced brickwork technology, employing unit weight is light, thermal conductivity factor is little, the heat resisting temperature height, and easy-sintering does not have the full fibre castable of amorphous refractory of higher-strength, with the overall structure of die casting moulding, making furnace lining is an integral body.Adopt this advanced person's furnace building process, the furnace insulation performance is good not to the utmost, and air-tightness is good, and heat loss is few, easy-sintering not, long service life can also satisfy variety classes, the structure of different model resistance furnace simultaneously, the geomery designing requirement, improved processing characteristics and made furnace building process simple, standardization, seriation degree height.
1. both sides furnace lining: adopt the die casting moulding of full fibre castable.Resistive band fixedly be that the heat resisting steel pillar that will make penetrates with refractory material and gives in the little cover of the insulation of making and the hanger of making, be fixed on the both sides of furnace lining, resistive band can hang on the hanger by its shape.Adopt and thisly be linked with mode fixedly the method for heating wire (band) is simple than the extension brick of traditional electric furnace.Laborsaving, change, maintenance is all very convenient.And this hanger is made simple, and the intensity height is not fragile, the service life of having improved heating simultaneously.
What be equipped with air blanketing between furnace lining and furnace lining and tapetum fibrosum solely holds structure, alumina silicate fibre blanket that thermal conductivity factor is little and pearlite insulating layer in addition, thus strengthened the heat insulation effect of body of heater, reduce heat loss.Utilize full fabric integer cast, the characteristics of air blanketing, the insulation material in the body of heater is the energy-conservation key link that the utility model is set forth in addition.
2. furnace lining base plate, trench structure adopt steel fibre to strengthen castable refractory, use the die casting moulding.This material has advantages of higher tensile strength and thermal-shock resistance preferably, and anti-mechanical wear selects for use this material can improve the intensity and the weight capacity of trench structure.Be to strengthen thermal cycle in the stove, having changed the transition of former right angle in design in furnace bottom and wall junction, furnace side is garden arc interim form, has avoided like this dead angle generation thermal chocking occurring because of the right angle transition.Thermal cycle in employing garden arc transition enhancing stove has improved temperature uniformity, has reduced heat loss.In the trench structure of drop-bottom the ribbon heater is housed, its extension method is identical with the furnace side wall, light-weight brick is arranged below the furnace bottom, the diatomite insulation, and the brick pearlite insulating layer plays good heat insulation effect.
3. furnace lining top board, be combined into domes by some sizes according to the full fibrous structures that the stove size determines, adopt seam to connect between every, this version, manufacturability, sealing are all fine, the intensity height, and the gap location between seam also is placed with alumina silicate fibre blanket, has solved the member problem of expanding with heat and contract with cold, at the alumina silicate fibre blanket of also packing into of the binding site between the wall behind body of heater side wall and body of heater top board and the stove, equally also solve the problem of expanding with heat and contract with cold, be convenient to maintenance.In order to increase thermal cycle, in the design of stove roof plate, also having changed furnace lining and the right angle transition of stove roof plate junction is garden arc transition.
4. wall behind the furnace lining is by the die casting moulding of full fibre castable.Its outside is a tapetum fibrosum, pearlite insulating layer.
5. fire door:, in the fire door design, adopt stepped construction, and be provided with self-locking device by the die casting moulding of full fibre castable.This version has solved the fire door problems such as easily heat radiation that are not closed completely, and has reduced heat loss, and fire door is closed tightly.The forms of motion that the unlatching of fire door adopts camber line to combine with translation makes the fire door lifting flexible, easy to operate, safe and reliable, and has avoided gnawing the limit phenomenon.
6. heating is used the infrared coating new technology
Scribble the width of cloth that infrared coating (reverse side does not have) improved heating element heater in the ribbon heater towards a side of burner hearth workpiece and penetrate heat, further played energy-conserving action, this new technology is applied on the resistive band more more remarkable than being used on the resistance wire its energy-saving effect.
7. the utility model is divided into two kinds on version, i.e. monoblock type and split type two kinds.The monoblock type resistance furnace is a chamber type electric resistance furnace, and split type resistance furnace is desk-top electric furnace.The general volume of car type furnace is bigger, and body of heater is longer, and furnace bottom is what to separate with body of heater, during workpiece loading and unloading, can be with the furnace bottom part along body of heater, and the guide rail direction shifts out, and is convenient to the loading and unloading of workpiece, prevents that also furnace bottom from damaging.This car type furnace is applicable to the heat treatment of the heavy workpiece that size is big.Whole or split typely all adopted same furnace lining structure on manufacturing and designing on the structure, its technical performance of heat-resistant insulation material and furnace building process is identical.
8. the utility model resistance furnace adopts optimal design, science selection, advanced person's brickwork technology, air blanketing unique texture on furnace binding, the infrared coating new technology is used and the burner hearth and the terraced wall furnace door of garden arc in addition, thereby it all shows outstanding advantage and characteristic than the structure of traditional resistor stove and technical performance, economic indicator.
Through power-saving technology center, Beijing to this stove actual measurement and the city is energy-conservation does, the expert of Xi-an Inst. of Electric Furnace and heat treatment industry identifies the utility model, prove that the true energy-saving effect of above set forth is remarkable, the product structure design novelty, rationally, body of heater is light, energy consumption is low, good heat insulating, furnace temperature is even, the high quick heating of the thermal efficiency, sturdy and durable, use easy to maintenance, every performance indications and technical parameter all meet and exceed the national standard requirement, the overall target ideal, this product occupies product of the same type leading position, have very much the use valency to put, and suggestion is applied in the city.Thereby prove the effect of the improvement of traditional stove having been played energy savings, reached improved purpose.
