Description
Technical field
This utility model belongs to Casting Equipment technical field, is specifically related to a kind of novel natural gas furnace cupola.
Background technology
So far, the foundry industry in the whole world is in the iron casting production accounting for foundry goods total output more than 80%, and its molten iron melts
Refining is still based on coke furnace cupola, so that cast iron melting becomes one of topmost polluter of casting industry.
The mankind, in order to protect environment, eliminate casting pollution, use clear energy sources-natural gas to substitute with serious pollution Jiao
It is the most imperative that charcoal carries out cast iron melting.The foundry industry in the whole world has been engaged in natural gas cupola exploitation application origin
For a long time, but effect is the most unsatisfactory, existing domestic and international natural gas cupola, all there is a common problem,
That is exactly: 1. dependability poor, 2. the operation life-span short, 3. refractory consumption rate greatly, 4. reconditioning work amount
Greatly, 5. energy consumption is higher.
Summary of the invention
The purpose of this utility model is to solve existing natural gas cupola to have that dependability is poor, the operation life-span
Technical problem short, that refractory consumption rate big, reconditioning work amount is big and energy consumption is higher, it is provided that a kind of natural gas
Furnace cupola.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of novel natural gas furnace cupola, including the dust hood that goes out, chimney, furnace charge charge door, hot-blast stove chamber and perpendicular
Stove, described in the dust hood that goes out be located at the top of chimney, the lower end of chimney is connected with the upper end of furnace charge charge door, furnace charge
The lower end of charge door is connected with the upper end of hot-blast stove chamber, and the lower end of hot-blast stove chamber is connected with the upper end of shaft furnace, its
In: it also includes rotary furnace, oxygen-enriched blasting pipeline, combustion of natural gas nozzle and pipeline support, described oxygen-enriched
Air supply duct is located in the middle part of the bell of rotary furnace, combustion of natural gas nozzle be located at oxygen-enriched blasting pipeline bottom and
Being positioned at the air outlet of oxygen-enriched blasting pipeline, pipeline support is located at the right-hand member of rotary furnace for supporting oxygen-enriched blasting
Pipeline and combustion of natural gas nozzle, the bottom of shaft furnace is provided with natural gas thermal-flame and enters burner and the mouth of a river of tapping a blast furnace,
Natural gas thermal-flame enters burner and is connected with the natural gas thermal-flame crater of rotary furnace by passing a bridge, and taps a blast furnace
The mouth of a river is connected with the molten iron mouth that enters of rotary furnace.
The furnace bottom of described shaft furnace is spherical crown shape, in the annular being provided around the brick one-tenth of forming graphite at the bottom of vertical furnace
Fusing quirk.
This utility model uses above technical scheme, and molten iron is overheated by Roarykiln furnace wall heat exchange pattern,
Greatly reduce temperature of furnace lining, be effectively increased heat conduction efficiency, substantially prolongs the life-span of forehearth furnace wall；
The annular being provided with the brick one-tenth of forming graphite in the bottom of shaft furnace inner chamber melts quirk, conveniently controls burn-off rate,
The annular quirk life-span can reach more than more than 10 heats, and simple in construction, build by laying bricks or stones conveniently, maintenance easily, use
Reliably, life-span length, that brickwork repaiies stove is with low cost.Therefore, compared with background technology, this utility model has
The advantage that good reliability, operation life-span length, refractory consumption rate are little, reconditioning work amount is little and energy consumption is low.
