Abstract

The utility model discloses a hood-type annealing furnace with large stacking quantity, strong annealing capability, unchanged height and lower consumption, which comprises an outer hood, an inner hood, a material disc, a base plate, a guide plate and a furnace table base, wherein the outer hood is arranged above the furnace table base with the diameter being 3.85m and is internally provided with the inner hood with the diameter being 3.35m; the material disc with the diameter being 1.5m and the base plate with the diameter being 3.2m are arranged below the inner hood; the furnace table base and the outer hood as well as the inner hood are round and are matched; the material disc is provided with a hole; the guide plate is arranged between the base plate and the furnace table base; the central space of the guide plate is provided with an impeller of a strong circulating fan; the furnace table base is provided with a motor of the strong circulating fan; and the outer hood is a heating hood with the diameter being 4.2m or a cooling hood with the diameter being 3.55m. With the design, annealing material coils can be arranged in three stacks in the shape of a Chinese character 'pin' (meaning quality), therefore, the annealing capability and the production efficiency of a single furnace are greatly improved, the plant area is effectively saved, the fuel gas consumption is decreased, and the production cost is reduced.

Description

A kind of bell type annealing furnace

Technical field

The utility model relates to a kind of Equipment for Heating Processing, and more particularly, it relates to a kind of bell type annealing furnace.

Background technology

Along with the production-scale expansion of enterprise, the anneal capability deficiency has restricted the expansion of throughput.Because of original bell type annealing furnace (Fig. 4), part dimensions such as chassis, inner cover, outer cover, charging tray are less, pile up so the annealing material can only singly be piled up neatly (Fig. 5), and batch is few, and anneal capability is little, and productivity is lower, has influenced the quick growth of annealing amount, has restricted the production of enterprise.If increase the restriction that the bell type annealing furnace height is subjected to workshop and sling height again, increase enterprise's production cost.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provide that a kind of amount of piling up is big, anneal capability by force, highly constant, consume the bell type annealing furnace that descends.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

Comprise outer cover, inner cover, charging tray, chassis, flow deflector, table base, described diameter is that 3.85 meters table base tops have outer cover, it is 3.35 meters inner covers that diameter is arranged in the described outer cover, being placed with diameter under the described inner cover is that 1.5 meters charging trays and diameter are 3.2 meters chassis, described table base and outer cover, inner cover are the circle that is complementary, described charging tray is provided with the hole, between chassis and table base, be provided with flow deflector, described flow deflector central space is provided with strong air circulation fan impeller, and described table base is provided with strong recirculation blower motor.

Described outer cover is 4.2 meters heating mantleses of diameter or 3.55 meters cooling cowls of diameter.

The utility model bell type annealing furnace has following beneficial effect compared with prior art:

This design can make annealing material volume be isosceles triangle three buttress and pile up, and increases substantially the anneal capability and the production efficiency of single stove, effectively saves the workshop area, and gas consumption descends, and lowers production cost.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, above diameter is 3.85 meters table bases 5, outer cover is arranged, the lifting of employing overhead traveling crane, during the heating of this outer cover for outer be the heating mantles 1 of the double-layer structure that is paved into of refractory fibre for iron and steel housing, internal layer, described diameter is that 4.2 meters heating mantleses 1 are equipped with interchanger 12, fixes its position by reference column 6 in use; During cooling 3.55 meters cooling cowls 2 of diameter.It is 3.35 meters inner covers 13 that diameter is arranged in the described outer cover, and the wall thickness of described inner cover 13 is 8mm.It is that 1.5 meters charging trays 10 and diameter are 3.2 meters chassis 3 that described inner cover is placed with diameter for 13 times, described table base 5 and outer cover, the circle of inner cover 13 for being complementary.3 centers, described chassis are provided with hole, chassis 8, apart from ground 700mm; Between chassis 3 and table base 5, be provided with flow deflector 4, described flow deflector 4 is for last lower plane or upper surface is the plane, lower surface is the high arc in low edge, center, described flow deflector 4 central spaces are provided with strong air circulation fan impeller 9, the position in hole, chassis, impeller 9 top 8 is provided with netted fence, described strong recirculation blower motor 7 is provided with shell, and this shell is fixed on the load-bearing ring flange.Described charging tray 10 is provided with hole and the gap of being convenient to furnace atmosphere circulation, is placed with material volume 11 on charging tray 10, and strong recirculation blower is heated evenly material volume 11 by furnace atmosphere circulation.

Annealing material on this bell type annealing furnace charging tray is isosceles triangle three buttress and piles up, make single furnace annealing amount be increased to the 60-70 ton, increase substantially anneal capability, more save the workshop area than increasing annealing furnace quantity from original 20-30 ton, ton steel gas consumption decline 20-30% has lowered production cost.

The above only is an example of the present utility model, and simultaneously example does not limit the utility model, and is all within spirit of the present utility model and principle, any modification of being done, is equal to replacements, improvement etc., all should be included within practical protection domain.
