Abstract
The utility model discloses a heating furnace tube for a coke thermal performance test furnace with an electric furnace heating wire insulating layer. The heating furnace tube comprises a heating furnace tube body, and an insulating layer is wrapped on the outer wall of the heating furnace tube body. Compared with the prior art, the speed at which electric furnace heating wires expand out of a groove of the furnace tube is reduced, and the contact opportunity of the electric furnace heating wires is inhibited, so that the service life of the heating furnace tube is prolonged and the thermal insulation performance is improved.
Description
Technical field
The utility model relates to the coke hot property trial furnace in a kind of metallurgical technology, specifically, relates to a kind of coke hot property trial furnace furnace tubing that is provided with the electric furnace heating wire heat-insulation layer.
Background technology
The heating element heater of coke hot property trial furnace is electric furnace heating wire, in coke hot property process of the test, electric furnace heating wire is under the acting in conjunction of long-time heating and the rapid cooling of off-test, through use after a while, electric furnace heating wire expansion after-contraction ability weakens, feasible original resistance wire bulging groove in the boiler tube groove, when continuing to use again, adjacent electric furnace heating wire is in contact with one another owing to adding the thermal expansion meeting, causes short circuit, and whole furnace tubing is scrapped.
The utility model content
The technical problem that the utility model solves provides a kind of coke hot property trial furnace furnace tubing that is provided with the electric furnace heating wire heat-insulation layer, can suppress the chance that electric furnace heating wire is in contact with one another, and makes furnace tubing prolong service life, and improves heat-insulating property.
Technical scheme is as follows:
A kind of coke hot property trial furnace furnace tubing that is provided with the electric furnace heating wire heat-insulation layer comprises furnace tubing, and the outer wall of described furnace tubing is enclosed with heat-insulation layer.
Further: the two ends of described furnace tubing are provided with cutting ferrule.
Further: be provided with electric furnace heating wire in the boiler tube groove in the described furnace tubing outside.
Further: the parcel scope of described heat-insulation layer is greater than the winding scope of described electric furnace heating wire.
The utility model is compared with prior art, can delay the speed of electric furnace heating wire bulging boiler tube groove, suppresses the chance that electric furnace heating wire is in contact with one another, and makes furnace tubing prolong service life, and improves heat-insulating property.
Description of drawings
Fig. 1 is the structure chart that is provided with the coke hot property trial furnace furnace tubing of electric furnace heating wire heat-insulation layer in the utility model.
The specific embodiment
Outer wall at furnace tubing, utilize insulating heat insulating materials such as heat-preservation cotton, increase an integument, two is used with the cutting ferrule of the identical material of electric furnace heating wire and is blocked about furnace tubing, it is tightly encased furnace tubing, delay the speed of electric furnace heating wire bulging boiler tube groove, suppress electric furnace heating wire and be in contact with one another, make the furnace tubing heat-insulating property improve, prolong service life.
Below with reference to accompanying drawing and preferred embodiment, technical solutions of the utility model are described in further detail.
As shown in Figure 1, be the structure chart that is provided with the coke hot property trial furnace furnace tubing of electric furnace heating wire heat-insulation layer in the utility model.The structure that is provided with the coke hot property trial furnace furnace tubing of electric furnace heating wire protective device comprises: furnace tubing 11, electric furnace heating wire 12, heat-insulation layer 13 and cutting ferrule; electric furnace heating wire 12 is positioned at the boiler tube groove in furnace tubing 11 outsides; the outer wall of furnace tubing 11 is enclosed with heat-insulation layer 13, and cutting ferrule is arranged on furnace tubing 11 two ends.
Work progress is as follows:
Get the furnace tubing that winds electric furnace heating wire 12 11 of a φ 140mm * 640mm, near the thick heat-insulation layer 13(material selection insulating heat insulating material of its outer wall parcel one deck 3 ~ 5mm, select heat-preservation cotton in this preferred embodiment for use), the parcel scope of heat-insulation layer 13 is greater than electric furnace heating wire 12 winding scopes, electric furnace heating wire 12 is pressed in the boiler tube groove, uses with the cutting ferrule of the identical material of electric furnace heating wire and block in two about in the of 11 at furnace tubing.Light filling high-alumina brick prefabricated component between furnace shell and heat-preservation cotton connects electric furnace heating wire 12 two ends and furnace shell again.
After the utility model installed, begin to heat up and carry out the test of coke hot property.Because of the effect of heat-insulation layer 13, to a certain degree the end, delay the speed of electric furnace heating wire 12 bulging boiler tube grooves, suppresses the chance that electric furnace heating wire 12 is in contact with one another, and makes furnace tubing prolong for 11 service lifes, and improve heat-insulating property.
Claims (4)
