Description
Technical field
The utility model relates to steel ingot demoulding annealing kiln, specifically a kind of insulation pit annealing furnace.
Background technology
For a long time, the high-carbon high-alloy steel grade being representative with W6Mo5Cr4V2, Cr12MoV, CrWMn etc., because its steel ingot internal stress is large, hardness is high, crystallographic texture is complicated, therefore ingot quality control difficulty is large, particularly surface of steel ingot lobe such as to burst at the problem, is the main Quality of special steel steel-making always.
The method that the steel-making of most of special steel adopts is 800 DEG C ± 10 DEG C time after the steel billet demoulding, directly load to be heated to >=annealing furnace of 700 DEG C in, after steel billet reaches shove charge quantity by the time, performs intensification, insulation, annealing process of lowering the temperature, this is attire annealing process.Or after steel billet 800 DEG C ± 10 DEG C demouldings, loading the holding pit built with coke, char combustion heat-dissipating ensures holding pit temperature-stable, then reach after some amount until steel ingot, load in annealing furnace together, perform the annealing process of intensification, insulation, cooling, this is hot charging annealing process again.General ingot mold and the weight ratio of steel ingot are greater than 1.5:1, cause the process for processing cycle long, and steel billet attire is annealed or hot charging annealing steel billet enters furnace operating difficulty, and labour intensity is large; And once steel billet process not in time, between 700 DEG C-800 DEG C, chilling can cause steel billet lobe or the quality problems such as seriously burst.
Utility model content
The utility model is intended to solve above-mentioned steel ingot demoulding annealing Problems existing, and a kind of insulation pit annealing furnace integrating holding pit and annealing furnace function is provided, steel ingot is incubated, annealing two procedures is combined into a procedure, with the quality problems such as effectively solve rapid tool steel, the cold and hot lobe caused in the demoulding, insulation, annealing process without magnetic die steel and alloy tool steel bursts.
The technical scheme that the utility model solves the employing of described problem is:
A kind of insulation pit annealing furnace, comprise body of heater, bell, heating tube, below described body of heater embed wholly earth's surface, in depression hole structure, outer body of heater is made up of high-temperature flame-proof cement furnace wall, high-temperature flame-proof cement furnace wall medial surface adds adiabator layer, and internal layer body of heater is formed by being incubated brick wall, and heating tube is placed between described adiabator layer and described insulation brick wall; Bell is made up of the lagging material of filling in the shell of Plate Welding and shell, and it is suitable for reading that bell is placed in body of heater, bell and body of heater suitable for reading between be provided with stainless steel packing ring.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
Significantly can improve the quality of steel ingot tempering, greatly reduce lobe and the generation of quality problems such as bursting in annealing process, alleviate the labour intensity of worker simultaneously, improve the security of work, and serve the effect of certain save energy.
As preferably, the further technical scheme of the utility model is:
Described adiabator layer is installed at the high-temperature flame-proof cement furnace wall medial surface forming body of heater annular wall portions.
Described heating tube is the multiple resistance heating tubes be connected with the thermopair of watch-dog.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: high-temperature flame-proof cement furnace wall 1, resistance heating tube 2, bell shell 3, lagging material 4, insulation brick wall 5, stainless steel packing ring 6, adiabator layer 7.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is further elaborated the utility model, but embodiment does not form any restriction to the utility model.
See Fig. 1, the insulation pit annealing furnace that the present embodiment provides, be made up of body of heater, bell, heating tube three part, below body of heater embed wholly earth's surface, in depression hole structure, outer body of heater is made up of high-temperature flame-proof cement furnace wall 1, high-temperature flame-proof cement furnace wall 1 medial surface of body of heater annular wall portions adds adiabator layer 7, internal layer body of heater is formed by being incubated brick wall 5, heating tube is placed between adiabator layer 7 and insulation brick wall 5, and heating tube is the multiple resistance heating tubes 2 be connected with the thermopair of watch-dog; Bell is made up of the lagging material 4 of filling in the bell shell 3 of Plate Welding and shell, and it is suitable for reading that bell is placed in body of heater, bell and body of heater suitable for reading between be provided with stainless steel packing ring 6.
The quantity of resistance heating tube 2 and the concrete position of each resistance heating tube 2 are determined according to the steel ingot quantity of placing in stove.During ingot annealing, in advance stove is heated up, then will the steel ingot of anneal be needed directly to hang in stove, cover bell, utilize heating tube to heat in stove, anneal according to ingot annealing technique, only complete steel ingot insulation, annealing two procedures with a procedure thus.
The foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specification sheetss and accompanying drawing content are done, is all contained within interest field of the present utility model.
