Abstract
The utility model relates to a new-type steel billet slow cooling device, including bell and furnace body, the bell is installed on the furnace body top, is equipped with the heat preservation cotton in the bell, is equipped with the heat preservation in the furnace body lateral wall. The utility model has the advantages of reasonable design, with low costs, convenience safe in utilization guarantees the slow even cooling of steel billet to reduce the rejection rate, can extensively be used for the steelmaking field.
Description
Technical field
The utility model relates to a kind of attemperator, particularly relates to a kind of new-type steel billet annealing device.
Background technology
Steel billet need carry out slow cooling and handle after rolling, and some present steel mills adopt burial pits to carry out the slow cooling of steel billet, and the burial pit floor space is big, inconvenient operation, poor stability, steel billet is in temperature-fall period, cooling rate is unbalanced, and regional area does not have cooling-down effect, and the slow cooling effect is undesirable.When winter, in situ temperature was low, the special guiding principle that production shuts out was owing to sharply cooling, and interior tissue changes, and variation has taken place the performance that causes, and also can produce internal fissure when serious, has had a strong impact on quality product.The easy landing of steel billet in stacking procedure simultaneously, abnormally dangerous, easily cause personnel's injury accident.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, easy-to-operate, the new-type steel billet annealing device of high insulating effect.
In order to address the above problem, the utility model by the following technical solutions:
A kind of new-type steel billet annealing device comprises bell and body of heater, and bell is installed in the body of heater top, is provided with insulating cotton in the bell, is provided with thermal insulation layer in the sidewall of the furnace body.
Described bell bottom is provided with breather hole, and breather hole one end is communicated with insulating cotton in the bell, and an end is communicated with the body of heater inner chamber.Be provided with first thermal insulation layer, second thermal insulation layer and the 3rd thermal insulation layer in the described sidewall of the furnace body, the first thermal insulation layer both sides are provided with second thermal insulation layer, and the second thermal insulation layer side is provided with the 3rd thermal insulation layer.
Described first thermal insulation layer adopts refractory materials to make; Second thermal insulation layer adopts the lightweight aluminium brick to make; The 3rd thermal insulation layer adopts insulating cotton to make.
Compared with prior art, the beneficial effects of the utility model are:
The utility model reasonable in design, cost is low, and floor space is little, adopts multilayer insulant, and high insulating effect prevents that steel billet from rapid refrigerative phenomenon taking place, and has effectively guaranteed the quality of steel billet finished product, has improved the performance of enterprises.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of new-type steel billet annealing device as shown in Figure 1, comprises bell 1 and body of heater 2, and bell 1 is installed in body of heater 2 tops, is provided with insulating cotton 3 in the bell 1, is provided with thermal insulation layer in body of heater 2 sidewalls.Bell 1 bottom is provided with breather hole 4, and breather hole 4 one ends are communicated with insulating cotton 3 in the bell 1, and an end is communicated with body of heater 2 inner chambers, can prevent bell 1 distortion.Being provided with first thermal insulation layer 5, second thermal insulation layer 6 and the 3rd thermal insulation layer 7, the first thermal insulation layers 5 both sides in body of heater 2 sidewalls is provided with second thermal insulation layer, 6, the second thermal insulation layers, 6 sides and is provided with the 3rd thermal insulation layer 7.Wherein, first thermal insulation layer 5 adopts refractory materials to make; Second thermal insulation layer 6 adopts the lightweight aluminium brick to make; The 3rd thermal insulation layer 7 adopts insulating cotton 3 to make.The utility model device adopts multilayer insulant, and heat insulation effect is good, makes steel billet slowly cool off, and has improved the final product quality of steel billet.
