Abstract
This utility model provides blast furnace tapping main channel, it includes the rectangular body using castable cast to be formed, body top caulking groove along its length, if being embedded with hondo brick in caulking groove along its length, connecting portion between adjacent ditch brick is provided with the concavo-convex position cooperated, described ditch brick brick body is divided into iron wire position, bottom and top slag lining, its slag lining uses slag line castable castable, iron wire position uses ASC iron wire castable castable, ditch brick top after combination is provided with up big and down small trapezoidal fluid slot, recessed arc rounding off is used bottom fluid slot, the gradient of fluid slot is 5 ~ 8%；Heat insulation adhesive layer it is provided with between ditch brick and main body.This programme uses combination type ditch brick, decreases replacing and the maintenance cost of material, effectively prevent waste.
Description
Technical field
This utility model relates to blast-furnace technique field, refers in particular to a kind of blast furnace tapping main channel.
Background technology
The construction technology that the most single ferrum mouth blast furnace iron outlet groove mainly uses is: tap drain uses the design of non-iron storage type, and the gradient is about 5%, and tap drain working lining uses the construction of ramming mass ramming, when needing in using to repair, uses ramming mass ramming to repair.Such iron runner ditch exposes in atmosphere after foiling ferrum, serious by rapid heat cycle and air oxidation, and short texture, not resistance to erosion, generally uses and can only use 3-5 days, causes repairing frequently, and labor strength is big, and refractory consumption is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of service life length, maintenance cost is low, refractory consumption is low blast furnace tapping main channel.
For achieving the above object, technical scheme provided by the utility model is: blast furnace tapping main channel, it includes the rectangular body using castable cast to be formed, body top caulking groove along its length, if being embedded with hondo brick in caulking groove along its length, connecting portion between adjacent ditch brick is provided with the concavo-convex position cooperated, described ditch brick brick body is divided into iron wire position, bottom and top slag lining, its slag lining uses slag line castable castable, iron wire position uses ASC iron wire castable castable, ditch brick top after combination is provided with up big and down small trapezoidal fluid slot, recessed arc rounding off is used bottom fluid slot, the gradient of fluid slot is 5 ~ 8%；Heat insulation adhesive layer it is provided with between ditch brick and main body.
Described body top both sides are provided with suspension ring, and suspension ring use the n shape that screw-thread steel is bent into, and pour into a mould fixing bottom n shape together with main body.
This utility model is after using such scheme, ASC iron wire castable and slag line castable is used to separate the way of castable, ensure that tap drain slag line part is consistent with iron wire part overall wear degree, effectively extend tap drain bulk life time, use combination type ditch brick, decrease replacing and the maintenance cost of material, effectively prevent waste.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is side view of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, blast furnace tapping main channel described in the present embodiment includes the rectangular body 1 using castable cast to be formed, main body 1 top caulking groove along its length, if being embedded with hondo brick 2 in caulking groove along its length, connecting portion between adjacent ditch brick 2 is provided with the concavo-convex position cooperated, described ditch brick 2 brick body is divided into iron wire position, bottom and top slag lining, its slag lining uses slag line castable castable, iron wire position uses ASC iron wire castable castable, ditch brick 2 top after combination is provided with up big and down small trapezoidal fluid slot, recessed arc rounding off is used bottom fluid slot, the gradient of fluid slot is 5 ~ 8%；Being provided with heat insulation adhesive layer 3 between ditch brick 2 and main body 1, described both sides, main body 1 top are provided with suspension ring 4, and suspension ring 4 use the n shape that screw-thread steel is bent into, and bottom n shape, cast is fixing together with main body 1.ASC iron wire castable is made up of electric smelting dense alumina, Brown Alundum, plate diamond spar, active oxidation aluminium powder, schmigel, carborundum, pelletted pitch, metal dust, sodium hexameta phosphate, coagulant, anti-knock agent and silica flour, slag line castable is added adjuvant by the molten magnesia of special grade bauxite grog and electricity and is formed, heat insulation adhesive layer pure calcium aluminate cement, pelletted pitch, metallic silicon power, nanometer silicon aluminium gel powder are made, and heat insulation bondline thickness is 10 ~ 15mm.The present embodiment uses ASC iron wire castable and slag line castable to separate the way of castable, ensure that tap drain slag line part is consistent with iron wire part overall wear degree, effectively extend tap drain bulk life time, use combination type ditch brick, decrease replacing and the maintenance cost of material, effectively prevent waste.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
