Abstract
The utility model relates to a high-preservation thermal insulation device, in particular to a high-temperature resistant thermal insulation beam at the furnace mouth of an annealing furnace. A beam is fixed at the top of the furnace mouth of the annealing furnace. A rail is fixed at one end of the beam by a nut. A thermal insulation beam body is hung at the lower end of the rail by a lifting lug. An air curtain fan is fixed outside the thermal insulation beam body. The high-temperature resistant thermal insulation beam has high thermal insulation performance and is not deformed and cracked.
Description
Technical field
The utility model relates to a kind of heat insulating device, particularly the heat insulation beam of annealing furnace fire door.
Background technology
The heat insulation beam of high temperature continuous annealing furnace fire door of the centrifugal cast iron pipe of water-cooled metal mould rotary casting at present generally adopts high temperature casting material feeding cast to form, and uses anchored brick to hang, and it mainly acts on is heat insulating, and can guarantee the cleaning of fire door outside atmosphere.In actual production, there is certain defective in this structure, and the start-stop stove during owing to maintenance causes temperature to cold and heat succeed each other fast, and heat insulation beam is easy to crack, and production is caused a hidden trouble, and severe patient causes cave-in accident, influence time.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of annealing furnace fire door high temperature insulation beam, and its heat-proof quality is good, and is indeformable, do not ftracture.
The technical scheme in the invention for solving the technical problem is: the fire door top fixed cross beam of annealing furnace, and an end of crossbeam is by the nut fixed railing, and the lower end of railing hangs with heat insulation beam body by hanger, the external fixedly air curtain of heat insulation beam blower fan.
The utility model not only is incubated, good heat-insulation effect, and architecture is simple, and is in light weight, is easy to install.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the A-A sectional view among the utility model Fig. 1.
Embodiment
As shown in drawings, the fire door top fixed cross beam 6 of annealing furnace 2, an end of crossbeam 6 is by nut fixed railing 5, and the lower end of railing 5 hangs with heat insulation beam body 7 by hanger 4, heat insulation beam body 7 external fixation air curtain blower fans 8.
Described heat insulation beam body 7 is for adopting the refining high temperature resistant crystal fibre module 3 that forms of colloid method.It has good thermostability and heat-shock resistance, can keep flexibility below 1500 ℃, and anti-airflow scouring is strong, the heat reflection performance height, and fibrous elasticity is good, and high-temperature shrinkage is little, low heat capacity, low heat conductivity, excellent chemical stability, good erosion-resisting characteristics.
Described heat insulation beam body 7 is compressed by internal stent by crystal fibre blanket folding forming, the external stability back up pad, and top is hanger 4 fixedly.Simple in structure, be easy to install, dismantle.
