Abstract
The invention relates to a box type groove form heating furnace which belongs to the technical field of heat treatment equipment and comprises a furnace casing, a lining, a furnace cover and an opening and closing mechanism of the furnace cover, wherein a furnace body is rectangular and has an upward-acting door, the furnace cover is connected with a weight box by two steel wire ropes through two rope pulleys, and the furnace cover, a wheel shaft, a sprocket wheel, a chain and a cranking bar form the opening and closing mechanism of the furnace cover together. The invention has various advantages of a box type resistance furnace, a trolley furnace and a well type resistance furnace and also has the advantages of simple structure, low price, convenient operation, small labor strength, good heat-insulating property, wide heat treatment range and the like that the three serial furnaces do not have. Compared with the resistance furnace of the prior art, the average electricity saving of the invention is 8-15%, and the invention is suitable for the conventional heat treatment of the annealing, the normalizing, the quenching, the refining, the tempering, the aging, the chemical heat treatment and the like of the large batch of metal workpieces.
Description
Affiliated technical field
The present invention relates to a kind of box type groove form heating furnace.
Background technology
In mechanical industry, be used to anneal, the resistance heading furnace of normalizing, quenching, modified, tempering and ageing treatment, mostly use chamber type electric resistance furnace, car type furnace and well formula resistance furnace.Chamber type electric resistance furnace exists large-scale workpiece to take on the shortcoming of stove difficulty, oven door sealing difference and hoisting appliance complexity thereof; Car type furnace has be easy to advantage, the shortcoming that have the furnace binding complexity, cost an arm and a leg, gas leakage face is big, thermo-efficiency is low though can handle large-scale workpiece, batch is big and take on stove; Well formula resistance furnace can only be used for thermal treatment heating such as the tempering, thermo-chemical treatment of middle-size and small-size workpiece.
Summary of the invention
The objective of the invention is reasonable in design to handle large, medium and small workpiece, take on that stove is convenient, simple in structure for the above-mentioned defective that overcomes prior art stove kind provides a kind of, low cost of manufacture, good airproof performance and the high box type groove form heating furnace of thermo-efficiency.
In order to achieve the above object, the present invention has mainly adopted following technical scheme to realize.The present invention is made up of annexes such as furnace shell, furnace lining, bell, opening and closing lid mechanism, heating unit and drop-bottoms.Described body of heater is upward-acting door, is rectangle, and heating unit is positioned over furnace bottom and both sides, front and back, is stamped the thick high temperature steel drop-bottom greater than 10mm on the furnace bottom heating unit.The bell heating surface is welded into by the thick heat-resisting steel sheet and plate of 6mm, the centre is welded with multiple tracks heat-resisting steel sheet and plate stiffening web, shell is welded into the thick general steel plate of 3-6mm according to the difference of stressed size all around, protuberance forms with the light fire brick laid on end under the bell, shop one deck fire-retardent fiber felt-rug above, pearlite insulating layer top have thicker refractory fibre thermal insulation layer again, have good heat-insulating property, bell is fixed on the top panel of stove outer covering by the web member of rear side, and we closes flexibly to make bell.The body of heater rear side designs a vertical angle-iron frame, and the angle-iron frame top is equipped with bearing, wheel shaft, double flute rope sheave and sprocket wheel, and interior upside is equipped with stage clip, and design has a ballast box in addition, is used to place configuration materials such as bushel iron.Bell is connected with ballast box by two rope sheaves by two wireline, upper sprocket wheel is connected with lower sprocket by chain, lower sprocket is equipped with crank, the keying of bell realizes by rotating crank, clockwise rotating the handgrip bell opens wide, rotate counterclockwise handgrip because the deadweight effect bell after the thrust of stage clip and the bell inclination can cover fire door automatically, it is very convenient to operate.
For large-scale bell, for alleviating bell weight, can adopt the dock bell, should adopt electronic opening and closing mechanism.
The present invention can built-in large-scale charging basket or material box, utilizes row to hang with instrument such as the electronic suspension bracket in gantry and can take on stove large-scale workpiece and part in enormous quantities, can carry out thermo-chemical treatments such as various conventional thermal treatments and solid in enormous quantities ooze.Because fire door pastes one deck fire-retardent fiber felt-rug along periphery, bell fastens tight, good heat insulating.Compare with car type furnace, have simple in structure, low cost of manufacture, energy-conservation about 15% advantage; Compare with chamber type electric resistance furnace, have easy to operate, labour intensity is little, energy-conservation about 8% advantage; Compare with well formula resistance furnace, have that batch is big, bell is simple in structure, an advantage such as homogeneous heating, price are low.The present invention has overcome the shortcoming of above-mentioned three big serial stove kinds simultaneously.

Fig. 2 is the right sectional view of body of heater of the present invention
Embodiment
Accompanying drawing has provided the specific embodiment of the invention.Shown in Fig. 1,2, the present invention mainly is made up of furnace shell (6), furnace lining (3), bell (2) and opening and closing lid mechanism.Between furnace shell and the furnace lining perlite (5) and refractory fibre (4) thermal insulation layer, furnace lining is built into by light fire brick, working spaces (14) is forward and backward to be equipped with electric stove wire heating units such as (13) with the bottom surface, furnace bottom is stamped drop-bottom (12), the bell shell is welded into according to the received heat various combination by heat-resisting steel sheet and plate and general steel plate, and its internal space is built to fill out by light cinder brick, perlite and refractory fibre and formed.Body of heater back design have open and close bell contain wireline (16), rope sheave (8), ballast box (11), sprocket wheel (9), chain (10), crank (1) and stage clip opening and closing mechanism such as (17); the stove left side is equipped with guard shield (7); bell and stove left side respectively have thermocouple jack (15); can insert two thermopairs; automatically control usefulness as furnace temperature for one, another is used as overtemperature prote.
The present invention can use under high, medium and low temperature state.Be applicable to conventional processing such as the annealing in enormous quantities, normalizing, quenching of mechanical industry metal works, modified, tempering, timeliness and thermo-chemical treatment.
