Because the utility model discloses a silicon nitride ceramic is outer as the armor, so insulating nature is good, the heat conductivity is high, and thermal shock resistance can be good, and it is even to generate heat, and heating efficiency is good. Suitable heating pipe as aluminium liquid foundry furnace is used.
Description
Technical field
This utility model provides ceramic field and is applied to the silicon nitride ceramics immersion of heating furnace and adds heat pipe.
Background technology
The heating furnace being currently used for melting aluminum liquid uses the heating of radiant type siliconit, and heat is by radiation, aerial conduction side
Formula, it is ensured that in-furnace temperature is constant, this mode of heating efficiency of heating surface is low, and heats uneven, is easily caused aluminum liquid oxide on surface
Increase, add aluminum liquid and consume without utilizing, too increase the generation of slag inclusion waste product；When adding aluminum liquid, it is necessary to drop heating power supply,
Need to stop producing, the seriality that impact produces；Siliconit adds its surface of heat pipe and is easily corroded by aluminum liquid and be destroyed, so using
Life-span is short.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of silicon nitride ceramics and adds heat pipe.This adds heat pipe and passes through
Silicon nitride ceramics shell is set outside flange resistance wire, solves to add heat pipe heating uniformly, the technical problem of insulating corrosion.
For above technical problem, using silicon nitride ceramics immersion to add heat pipe, siliconit is improved to immerse by this product
Formula heats, and this mode of heating can immerse and directly heat inside aluminum liquid, it is achieved that consecutive production pattern.The formula of being contemporaneously immersed in adds heat pipe
Being made up of silicon nitride ceramics pipe, flange resistance wire, silicon nitride ceramics pipe is a kind of novel structural ceramic material, goes through superhigh temperature
Prepared by non-oxidized substance technique, smooth surface, internal structure are fine and close；There is under hot conditions the electrical insulating property of excellence and good leading
Hot property, thermal conductivity is good, and heating rate is uniform, improves the thermal efficiency, reduces energy consumption；There is excellent thermal shock resistance, i.e.
Make not ftracture in the case of suddenly cold and hot；Stable chemical nature, it is possible to the erosion of resist melt metal, does not reacts with aluminum solutions, no
Viscous aluminum alloy melt, it is to avoid the introducing of impurity in aluminum liquid；Immersion heater is long for service life, extends the stage of replacement, cost-effective.
This utility model solves technical problem and says that the scheme used is:
The silicon nitride ceramics tube opening end at tubulose with an end closure is fixed with flange seal filler, at silicon nitride ceramics
Pipe, built with flange resistance wire, is filled with silicon nitride particle obturator around silicon nitride ceramics pipe inner flange resistance wire, in nitridation
Silicon pottery opening is provided with installation bayonet socket, is filled with cone seal filler at silicon nitride ceramics pipe root, will by clamping screw
Flange resistance wire is fixed on furnace shell.
Good effect, owing to this utility model employing silicon nitride ceramics is as armouring outer layer, so good insulating, thermal conductivity
Height, thermal shock resistance is good, and uniformly, the efficiency of heating surface is good in heating.Suitably the heat pipe that adds as aluminum liquid foundry furnace is applied.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart.
In figure, 1. silicon nitride ceramics pipe, 2. flange resistance wire, bayonet socket, 4. flange seal filler are 3. installed, 5. taper is close
Packing material, 6. clamping screw, 7. furnace shell.
Detailed description of the invention
According to the figure, silicon nitride ceramics pipe 1 opening at tubulose with an end closure is fixed with flange seal filler 4,
At silicon nitride ceramics pipe built with flange resistance wire 2, around silicon nitride ceramics pipe inner flange resistance wire, it is filled with silicon nitride particle
Obturator, is provided with installation bayonet socket 3 at silicon nitride ceramics opening, is filled with cone seal filler 5 at silicon nitride ceramics pipe root,
By clamping screw 6, flange resistance wire is fixed on furnace shell 7.
During use, silicon nitride ceramics is added heat pipe and is immersed in the middle of aluminum liquid, for heating and Insulating aluminium liquid.
Feature:
Silicon nitride ceramics pipe is used for melting zinc alloy casting heating and melting aluminum liquid, and tube wall rate of heat exchange reaches 85kW/m2, compare silicon
It is high 9 times that same molten metal surface area rate of heat exchange is heated in carbon-point radiation.Earthenware immerses in molten metal and heats, and passes with direct heat
Leading heating and replace radiation heating, the temperature of earthenware is close to temperature of aluminum liquid.Furnace roof and furnace wall temperature ratio are relatively low, and heat loss is few.Warp
Theoretical Calculation and test determination, if smelting aluminium alloy liquid humidity is 750 DEG C, then immerse earthenware outside wall temperature 751 DEG C, inside
825℃；Circulation pipe outside wall temperature is 1080 DEG C, inwall 1130 DEG C.
It is a kind of novel structural ceramic material that immersion adds the silicon nitride ceramics pipe of heat pipe, goes through superhigh temperature non-oxidized substance
The extraordinary technology of preparing of pottery, is a kind of super-hard compound material.Silicon nitride ceramics has high intensity, resistant to elevated temperatures feature, at pottery
In ceramic material, its comprehensive mechanical property is best, and resistance to thermal shock performance, antioxygenic property, abrasion resistance properties, corrosion resisting property are good.Silicon nitride
Chemical stability is good, is resistant to the erosion of acid-base solution and molten metal bath, is the first candidate material of heat engine parts pottery.
Along with the improvement of preparation technology, the heat conductivility of silicon nitride and dielectric properties have obtained significant raising.Can be used on electricity
In heating and conductive substrate.
