Description
Technical Field
The utility model belongs to the technical field of equipment is smelted in the casting, concretely relates to detachable assembly's intermediate frequency furnace beat stove core that stove lining was used.
Background
The intermediate frequency furnace is widely used for smelting and heating metal, such as smelting pig iron, common steel, stainless steel, tool steel, copper, aluminum, gold, silver, alloy and the like. The intermediate frequency furnace heating device has the advantages of small volume, light weight, high efficiency, excellent hot processing quality, environment friendliness and the like, and is a new generation of metal heating equipment which rapidly eliminates coal-fired furnaces, gas furnaces, oil-fired furnaces and common resistance furnaces.
The smelting temperature of the intermediate frequency furnace can reach 2000 ℃, when the intermediate frequency furnace is used, a furnace lining is required to be firstly beaten, specifically, a furnace core is firstly placed in the furnace, a refractory material with a certain thickness is beaten between the furnace core and the furnace chamber to form the furnace lining, and then a metal material to be smelted is added into the furnace core for smelting. The lining of the furnace is generally made of magnesia or quartz sand lining material, and the process is divided into wet beating and dry beating.
The wet-beating process is to add adhesive such as water, water glass, brine and the like into the furnace lining knotting material for knotting, and the knotting material contains certain moisture, so that the dust is less during construction, the formability is good, and the mold can be strongly pulled out. However, wet knotting also has a series of disadvantages, such as the knotted furnace lining material is not compact enough, and the refractoriness of the furnace lining is reduced to some extent; the time consumed by drying the furnace lining is longer; when moisture in a furnace lining is gasified, the insulation performance of the inductor is reduced, the breakdown of large interturn fire is often caused, and the grounding short circuit can also be caused, so that the dry blasting process is more in the prior art.
The dry striking process is to place the furnace core in a furnace and use an air cannon hammer to stamp and mold quartz sand, after the stamping operation is completed, because the furnace core is tightly attached to the stamped furnace lining and the furnace core has a certain depth, the furnace lining is easy to collapse or scratch and rub the just-formed furnace lining after being forcibly taken out, the furnace core and the materials in the furnace are often smelted together in the actual operation, and unnecessary loss is brought to production and experiments.
In order to save materials and further control the cost, the furnace core which is simple in structure, convenient to disassemble, rapid to operate and easy to popularize and use is designed, and has positive significance.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The embodiment of the utility model discloses detachable assembly's intermediate frequency furnace beats stove core that furnace lining was used, it is shown according to fig. 1 to 7, including lateral wall, upper cover 1, bottom plate 3, stand 6, the appearance and the furnace chamber adaptation of upper cover 1, bottom plate 3 are circular. The side wall is composed of at least 3 same arc-shaped side plates 2, and a plurality of arc-shaped side plates 2 are connected together to form a cylindrical structure. The upper end and the lower end of the arc-shaped side plate 2 form a detachable connection relation with the upper cover 1 and the bottom plate 3 respectively, and then a closed cylinder is formed. The upright 6 is vertically connected to the top surface of the bottom plate 3 and extends upward to the upper cover 2, and the bottom plate 3 can be lifted up by the upright 6 from above.
Furthermore, in order to make the structure succinct, reduce part quantity, convenient dismantlement, adopt tenon fourth of twelve earthly branches structural connection between arc curb plate 2 and upper cover 1, the bottom plate 3. The upper end and the lower end of the arc-shaped side plate 2 are provided with tenons 4, and the tenons 4 can be integrally formed with the arc-shaped side plate 2 or welded; be equipped with the mortise in the department that corresponds with tenon 4 on upper cover 1 and bottom plate 3, retrain arc curb plate 2 as an organic whole with upper cover 1, bottom plate 3 through tenon fourth of the twelve earthly branches structure.
The top surface of the bottom plate 3 is provided with an annular groove 7 which is concentric with the bottom plate 3, so that the tenon 4 can be conveniently inserted into the annular groove 7 at any position. The upper cover 1 is provided with a through hole 9 at a position corresponding to the tenon 4, the tenon 4 is inserted in the through hole 9, and the through hole 9 is matched with the tenon 4 to limit the arc-shaped side plates 2 to keep still. The upper tenon 4 and the lower tenon 4 of the arc-shaped side plate 2 are respectively inserted into the through hole 9 and the annular groove 7, and the posture of the arc-shaped side plate 2 is restrained by the through hole 9 and the annular groove 7 to keep stable, so that a stable cylinder structure is formed.
Further, in order to lift the bottom plate 3 more balance, the upright column 6 should be coaxially connected with the bottom plate 3, so that the bottom plate 3 is prevented from being inclined and rubbing the furnace lining during disassembly. The upright post 6 can be directly and vertically welded on the bottom plate 3, and also can be pre-provided with a threaded hole on the bottom plate 3, and the upright post and the threaded hole are welded after being connected by threads.
Still be equipped with screw thread 8 in 6 upper ends of stand, be connected with lug nut 5 on the screw thread 8, can hang away from bottom plate 3 perpendicularly through lifting by crane equipment, avoid bare-handed operation to take place the incline.
In order to facilitate disassembling the arc-shaped side plate 2, the diameter of the bottom plate 3 should be smaller than that of the upper cover 1, so that the cylinder formed by the arc-shaped side plate 2, the upper cover 1 and the bottom plate 3 has a certain taper. In addition, the central angle corresponding to the radian of the arc-shaped side plate 2 is less than 180 degrees, so that the width of the arc-shaped side plate 2 is ensured to be less than the diameter of the bottom plate 3, and the arc-shaped side plate 2 is ensured to incline inwards during disassembly without rubbing the formed furnace lining. The utility model discloses an optimal 4 pieces that are of quantity of arc curb plate 2.
The utility model discloses a lateral wall, upper cover 1, bottom plate 3 adopt tenon fourth of the twelve earthly branches structural connection each other, form a detachable cylinder, retrain each other between each part, and the structure is succinct compact, easy disassembly and stable in structure. The concrete use does, earlier with the utility model discloses the equipment shaping is placed into the furnace intracavity, smashes the furnace wall at its periphery, smashes when the furnace wall and beats the completion back, takes off upper cover 1 earlier, makes it break away from with arc curb plate 2 to the inboard slight incline, then one by one disassembles it, has avoided producing the friction with the furnace wall surface like this, can not destroy the furnace wall inner wall. We also weld stand 6 on bottom plate 3, after arc curb plate 2 was dismantled and is accomplished, can take out the bottom plate through drawing stand 6 perpendicularly. Because the contact surface of the bottom plate 3 and the furnace lining is small and the formed furnace lining has conicity, the bottom plate 3 can be taken out of the furnace lining very smoothly without damaging the inner wall of the furnace lining.
The utility model discloses can not cause the furnace wall to collapse or cut the rubbing furnace wall to pieces at disassembling the in-process, reuse that can also accomplish has simple structure, convenient to detach, operates advantage swift, the easy using widely.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
