Problems solved by technology

Hot delivery and hot charging of steel billets in iron and steel plants have become very common and have achieved good energy-saving effects. However, at present, hot billets are generally transported in an open manner. loss, the edge of the billet cools faster, and is prone to cracks for some steel types, which affects product quality. Some factories at home and abroad also take heating measures for the edge of the billet, and the furnace temperature is not high enough. Difficulties and cost performance issues have not been fully realized

Embodiment 1

[0030] Such as figure 1 As shown, the water internally cooled conveying slab roller table of a kind of heat preservation device provided by the present invention includes refractory fiber 1 filled in heat-resistant alloy steel (refractory fiber is filled with ceramic fiber or refractory castable) located in the heat preservation device , the roll ring 4 (available lcr25ni20si2 steel plate, the same below) can be made of lygx-421 from Luyang or the heat-resistant castable for hearth rolls developed by Madashan Iron and Steel Company, the same below), and the roll ring 4 is made of its The hot blank 5 transported, the roller ring 4 is arranged in the heat preservation box, and the first ceramic fiber special-shaped part 6 (lygx-355 available from Luyang) is provided on the contact surface of at least one end of the roller ring 4 and the side wall of the heat preservation device. , the same below), the roll ring 4 is welded to the water-cooled shaft 11, and the first shaft seal ...

Embodiment 2

[0033] Such as figure 2As shown, it is a schematic diagram of the cantilever roller table unit of the water internal cooling conveying slab with the heat preservation device. Connected, a garden ring 15 made of heat-resistant ductile iron (RQTSi-5.5, the same below) is set in the first shaft seal device 7, which is conducive to the leakage prevention of the shaft seal, and is separated from the roller ring 4 by a certain distance to reduce heat transfer. The bearing block 10 and the reducer 12 with frequency conversion motor are all installed on the mobile bracket 16, and the mobile bracket 16 is installed on the second roller table base 22, and the second roller table base 22 is equipped with a swing hydraulic cylinder 18, and the pushing force of the hydraulic cylinder 18 The garbage bar is connected on the mobile bracket 16, and the support 17 of the swing hydraulic cylinder 18 is installed on the second roller table base 22. When the flame cutting nozzle approaches the ca...

Embodiment 3

[0035] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the other end of the water-cooled shaft 11 is installed in the high-temperature oil-impregnated bearing and bearing seat 19 located in the heat-retaining cover 3, and the high-temperature oil-impregnated bearing and A water-cooling device is provided outside the bearing housing 19, and a second shaft seal device 24 is provided on the side of the high-temperature oil-impregnated bearing and the bearing housing 19. The outside is provided with a second ceramic fiber special-shaped part 26 for heat insulation, and the high-temperature oil-impregnated bearing and the bearing seat 19, the bearing seat 10 and the speed reducer 12 with the frequency conversion motor are all installed on the third roller table base 23.

Abstract

The invention provides a water internal cooling roller way with a heat preservation device, which is characterized in that the roller way comprises a roll collar which is arranged in the heat preservation device and filled with fire-resistant fiber; the roll collar is provided with a hot blank carried by the roll collar; the roll collar is arranged in the heat preservation device; a contact surface of at least one end of the roll collar and the side wall of the heat preservation device is provided with a first ceramic fiber special-shaped part; the roll collar is connected with a water internal cooling shaft; a contact surface of the roll collar and the water internal cooling shaft is provided with a first shaft seal device; the first shaft seal device is provided with a first air inlet; the middle part of the water internal cooling shaft is arranged on a bearing block; and one end of the water internal cooling shaft is arranged outside the heat preservation device and connected with a speed reducer of a variable frequency motor; and a water-cooling pipeline in the water internal cooling shaft is connected with a rotary joint. The water internal cooling roller way has the advantages of synthetically solving the connection relation of a heat preservation cover and the roller way, sealing and preventing heat dissipation to the maximum, having even temperature on the section of a plate blank, improving the product quality, reducing the consumption of steel, improving billet furnacing temperature, saving energy, saving investment, and having simple equipment structure, long service life and convenient maintenance.

Description

technical field [0001] The invention provides a water internally cooled conveying slab roller table with a heat preservation device, which is used in a hot billet hot delivery and hot charging device in a steel plant, and belongs to the technical field of steel billet transportation, hot billet hot delivery and hot charging, and energy-saving devices. Background technique [0002] Iron and steel enterprises are large energy consumers. High quality, energy saving, and consumption reduction are the goals that enterprises have always pursued. Energy saving and emission reduction are twin brothers. Energy saving is a benefit economic issue, and carbon emissions in emission reduction will now be a political issue. . Hot delivery and hot charging of steel billets in iron and steel plants have become very common and have achieved good energy-saving effects. However, at present, hot billets are generally transported in an open manner. loss, the edge of the billet cools faster, and ...
