Description
The utility model relates to a kind of metal material resistor furnace for heat treatment.
At present, adopt resistance furnace to carry out the metal material Technology for Heating Processing, generally use in China's mechanical processing industry, it is one of capital equipment in the heat treatment step, also is one of equipment of power consumption maximum in the electromachining equipment simultaneously.At present, the furnace lining of all kinds of resistance furnaces of domestic each manufacturer production, mostly be to form by refractory brick, refractory cement, the seat clay system of building, there is not air blanketing to be separated by between furnace lining and the housing, therefore big former solid of the outstanding power consumption of traditional resistance stove shows that mainly the furnace temperature heating-up time is long, and the interior heat-insulating property of body of heater is poor, easily heat radiation, the thermal efficiency is low.And body of heater is heavy, and furnace lining is low service life, and maintenance is inconvenient, and the Technology for Heating Processing inconvenient operation also is that material and the structure by body of heater determined.
The purpose of this utility model is that will to solve resistance furnace power consumption big, the problem of aspect such as the heating-up time is long, and the thermal efficiency is low, equipment heavily reaches door opened effort.
The purpose of this utility model is achieved in that
In the technology of design and manufacturing resistance furnace, changed material, planform and the process of former resistance furnace lining, specifically improve as follows:
1, the both sides furnace lining adopts full fibrous material, uses the die casting moulding.Full fibrous material is a kind of novel refractory material, and this material weight is light, heat resisting temperature height, easy-sintering not, long service life.Entire fibre lining has changed with hanging the fixedly method of heating wire (band) of brick, but the preformed hole when adopting cast, add the little cover that heat resisting steel is made in preformed hole respectively, little cover all is fixed on the heat-resisting steel band, and heat-resisting steel band and little cover are all in furnace lining the time is annotated in cast.This structure has promptly been fixed the little cover of hanger, becomes the skeleton of furnace lining again, has strengthened the rigidity of furnace lining.The hanger of respectively alumina silicate of two kinds of shapes being made when hanging the ribbon heater inserts in the preformed hole of liner plate, and the ribbon heater just can hang on the hanger by its shape, and this type of attachment is simply more laborsaving than traditional mode that is linked with, and is all more convenient when replacing, maintenance.The little cover of heat resisting steel in the furnace lining can be protected furnace lining material, prolongs the service life of furnace lining.All can protect preformed hole not to be damaged through repeatedly changing hanger or ribbon heater.The furnace lining that constitutes by full fibrous material, and also have air blanketing between the furnace shell, alumina silicate fibre blanket and perlite and cement mix the stirring thing, air blanketing also is a unique distinction in the utility model.Utilize the characteristics of air blanketing, other insulation materials in the body of heater are energy-conservation key links that the utility model is set forth in addition.
2, the base plate of furnace lining is that full fibrous material by trench structure pours into.The ribbon heater is housed in the groove, and its version is identical with side plate.Three parts that formed by light-weight brick, heat-resistant felt and perlite and cement admixture cast below the drop-bottom constitute, and these materials can load-bearing can play good heat insulation effect again.
3, the furnace lining top board is combined into domes by some sizes according to the full fibrous structures that the stove size determines.Type of attachment between every adopts seam to connect.This form good manufacturability, good airproof performance, intensity height have solved the problem that shrinkage heat rises simultaneously.Binding site between furnace lining side plate and furnace lining top board and the end plate alumina-silicate refractory fibre blanket of can packing into has solved the cold shrinkage and thermal expansion problem equally.
4, the end plate of furnace lining with full fibrous material by the template castable.And in the middle of the plate of whole back, be embedded with which floor alumina silicate fiber felt.The problem that the shrinkage heat that causes to solve the furnace temperature variation rises.Its outside is perlite and cement admixture.
5, the alumina silicate fibre blanket of the version that adopts air blanketing between resistance furnace lining and the housing around in addition and the thermal insulation layer of perlite and cement mixture filling, on version and selected heat proof material, many renewals and improvement are arranged all, Gu this it lighter than the body of heater of traditional resistance furnace, power consumption is few.Thereby reach cut down the consumption of energy, the purpose of energy savings.
6, the utility model is divided into two kinds from version, i.e. monoblock type and split type.The monoblock type resistance furnace is a feather cockscomb formula resistance furnace, can carry out integral hoisting and mobile.Split type resistance furnace generally all is that volume is bigger, and body of heater is longer.The part in addition that weight is big is heat-treated as roll frame etc.Split type resistance furnace, furnace bottom and body of heater are discerptible, its furnace bottom is to be fixed on the light rail by self transmission system, the furnace bottom part can be shifted out along the guide rail direction with body of heater during workpiece loading and unloading, is convenient to the loading and unloading of workpiece like this, also avoids the damage of drop-bottom.But two kinds of forms all select for use same furnace lining structure and insulation material therefore to reach same technical performance on the overall structure.
7, the unlatching of fire door, the forms of motion that adopts camber line to combine with translation, it has solved and has sealed bad and gnaw the limit phenomenon.On two side rails spring catch is housed, but its self-locking when closing fire door and can be adjusted the slit, this mechanism opens convenient, and is safe and reliable, need not be manually to other controlling organizations of open operation of fire door.
Because the utility model improves each relative section of body of heater, thereby in technical-economic index, fully demonstrate its outstanding advantage and characteristic.Twice actual measurement carried out to the utility model in energy-conservation center through Beijing.It is true observing and predicting in fact and accusing proof content explained above.Its mixed economy technical indicator is desirable.Gu the effect that this proof has played energy savings to the improvement of traditional stove has reached improved purpose.
With the test result at energy-conservation center, Beijing and the product of nineteen eighty-three Machinery Ministry evaluation, the key data of PX3-45-9 resistance furnace is represented below:
