Abstract
The invention discloses a kind of steam dewaxing kettle and process for dewaxing, it is steam jacket between the shell and inner bag of dewaxing kettle body, the inner bag is provided with multiple valves, it is provided with the acting chamber constituted by inner bag for fixing the fixing device of shell, tilting gearing drives dewaxing kettle body to incline, and dewaxing kettle body inclines and drives investment casting shell to incline to make its rising head and cast gate downward or obliquely downward；In dewaxing, high steam initially enters steam jacket and enters acting chamber by valve again, progressively opens valve, slow release of pressure after the completion of dewaxing.The present invention by steam jacket in high steam inner bag is preheated, reduce condensation, improve voltage built-up rate and wax liquor recovery utilization rate；What the multiple valves on inner bag made acting chamber faster builds pressure, it also avoid forming micro-crack on shell；Incline dewaxing kettle by tilting gearing, accelerate the wax liquor rate of outflow and eliminate the operation in the dewaxing hole that repairs on shell, improve production efficiency.
Description
Technical field
The present invention relates to dewaxing kettle, and in particular to a kind of steam dewaxing kettle.
Background technology
Model casting basic craft course can be divided into lost wax casting, shell manufacture and roasting cast.As shell is to casting
The casting quality for going out plays a key effect, and therefore the manufacture of shell itself is very crucial.Common shell processing technology includes：Wax
The oil removing and degreasing of mould, coating and stucco, shell is coated with wax-pattern dries and hardening, molten lose wax-pattern and roasting shell.
Material melting point due to manufacturing wax-pattern is generally relatively low, for the molten mistake of the wax-pattern of a small amount of, common shell can be put into boiling
In water.For large-scale shell or the occasion of large quantities of a large amount of productions, it usually needs special dewaxing kettle is completing the technique.
It is horizontal that existing dewaxing kettle is most.500 millimeters are much larger than in the case that the diameter of dewaxing kettle is general, conventional
The general height of typical casting system is 300 millimeters or 400 millimeters, and most 450 millimeters, this height can allow shell
Downward, wax-pattern can be downward under gravity after dissolving for the endways rising head and cast gate for being put into the dewaxing kettle, i.e. shell
Flow out.
When shell is more than 1 meter, it is impossible to be put into dewaxing kettle with vertical direction, the level of being only capable of is put into, such rising head cast gate direction
Now not down, just cannot flow out from rising head and cast gate after wax-pattern dissolves.In prior art, generally under the bottom of secondary running channel
Open up multiple de-waxing holes to discharge the wax-pattern after fusing, on the shell obtained after dewaxing, be left with a lot of holes.This some holes can drop
The firmness degree of low profile shell, after dewaxing in order to avoid cast when molten metal flow out shell also need to repair this some holes.Additionally, for water
Wax liquor still thoroughly cannot be excluded by the shell of placing flat, the de-waxing hole of secondary running channel bottom.
