Description
Technical field
the utility model relates to a kind of blast furnace component, particularly relates to a kind of blast furnace material distribution chute.
Background technology
blast furnace material distribution chute is a key part in iron-smelting blast furnace bellless distributor, is to smelt last passage that stream enters blast furnace, is distribution device raw material and solid fuel are distributed on request on shaft furnace transverse section.
in general, when the large feed distribution of lumpiness is in the central zone of stove, and less when should be distributed in the neighboring area of stove, raw material and fuel fuel reaction more fully in stove can be made, and current distributor chute is difficult to reach above-mentioned technique effect.
in addition, the Working environment due to distributor chute is in the effect of high temperature, blast furnace gas that aggressiveness is stronger, and is subject to the impact of high speed stream for a long time, very easily weares and teares, thus affects its work-ing life.
Summary of the invention
for above-mentioned technical problem, the utility model provides one can realize accurate cloth, and wear resisting property is good, constitutionally stable blast furnace material distribution chute.
a kind of blast furnace material distribution chute, it comprises arc substrate, arc liner plate and bracing frame; Wherein bracing frame is for connecting arc substrate and arc liner plate, and bracing frame is evenly distributed between arc substrate and arc liner plate, and its quantity is 3-5.Wherein arc outer surface of substrate is coated with refractory masses, for the protection of arc substrate surface, and the refractory materials that it is main component that refractory masses is selected with aluminum oxide, chromic oxide.Wherein arc liner plate is coated with carbide layers and hard alloy layer; be bottom with wolfram varbide during making; with manganese-copper as solder; hard alloy layer in soldering again; the carbide layers formed and Wimet Rotating fields are for the protection of arc liner plate; wherein hard alloy layer can be a Rotating fields, also can be bilayer structure.Bracing frame wear-resisting alloy steel is made, and wear-resisting alloy steel can select 38CrMoAl steel alloy.
the beneficial effect that the utility model brings is: 1, adopt multiple bracing frame to connect arc substrate and arc liner plate, can effectively realize bulk raw to be distributed in stove central zone, fritter feed distribution, in stove neighboring area, effectively improves efficiency of combustion.When 2, manufacturing arc liner plate, employing wolfram varbide is bottom, with manganese-copper as solder, by infiltrating the mode of welding, soldering one deck Wimet thereon, this welding process is compared with traditional built-up welding mode, welding quality is not better, easy to crack and come off, more than 1 year work-ing life of extension device.
