Abstract
The invention discloses a mouth used for a gravity-cast quantitative furnace. The mouth is a combination of a heating device, an inert gas control system and a liquid rising pipe. When the mouth is in use, aluminum alloy liquid is ensured to be protected by inert gas in the process of forming of protection liquid and a product, and oxide generation is effectively prevented. The mouth (9) is composed of a high-temperature-resistant non-stick aluminum mouth (3), a heating ring sleeve (6), an inert gas control valve (8), an inert gas delivery pipe (8-1), an inert gas blowing mouth (4) and a heat-insulating material, and the heating device is integrally formed with the liquid rising pipe (2), and inert gas flow is controlled by a programmable logic controller (PLC) system.
Description
Technical field
The quantitative stove of gravitational casting is with chewing the genus casting field.
Background technology
Gravitational casting is the common method of metal pattern casting.It drops into simple, easy to operate, but the manpower consumption is larger, and quality is also difficult stable.Adopt advanced technologies equipment machine people or the quantitatively alternative artificial cast of stove, but aluminum alloy melt during its cast still contact with atmosphere and can produce oxide skin, affect product quality, make product quality be difficult to control.
Summary of the invention
The quantitative stove of aluminium alloy of the present invention, with chewing by heater, inert gas control system and stalk combination, guarantees during use that aluminum alloy melt all obtains the protection of inert gas in the forming process of protecting liquid and product, effectively prevent the generation of oxide.This is chewed (9) and is chewed by high temperature resistant sticky aluminium that (3), heating snare (6), inert gas control valve (8), inert gas carrier pipe (8-1), inert blowing gas are chewed (4), insulation material (7) forms, with stalk (2) one, inert gas flow is controlled by programmable controller PLC system.
The accompanying drawing explanation.
Accompanying drawing 1 is the quantitative stove of the gravitational casting structural representation of chewing
Embodiment
The quantitative stove of the present invention is with chewing the discharging opening as aluminum alloy melt by the Yan Shengguanzui (3) of stalk (2), with not sticky aluminium earthenware, make, outsourcing ceramic electric heating cover (6) is at the additional heat-insulation layer of electric heating cover (7), electric heating cover (6) outer wall of chewing mouthful (3) puts conical flow guiding gas and blows and chew (4), blow and chew (4) collar extension and dish out and chew 5 millimeters, (3) plane, play the effect of water conservancy diversion inert gas; The opening fanning strip of the stainless steel case both sides of ceramic heat cover (6) outsourcing between will locating (12) to (3) before making removes a slice every one, utilizes gap between its pottery heat tunnel as inert gas; Water conservancy diversion gas blows the outside of chewing (4) and puts after polycrystalline cotton-padded covering (7) and fix with shell 10; Stainless steel inert gas tube (8-1) end is fixed on furnace shell (10) position, under pass to (12) in two electric jacket seams and locate; Inert gas tube (8-1) overcoat electric heating cover (6-1); The gas of sending into first enters in ceramic heat cover (6) after heating jacket (6-1) preheating again; Electric heating cover is controlled and is heated by (11) electroheat pair, guarantees that the temperature of aluminum liquid of inert gas temperature and use is close; Inert gas tube (8-1) upper end is connected with control valve (8), flow control valve (8) other end (5) access inert gas; Flow control valve (8) is pressed the technological order of programmable controller PLC system and is supplied with the setting flow, forms and sweeps mould use gas, annotates to press and use gas, protects liquid gas inert atmosphere, guarantees the pure of aluminium liquid use, annotates and extrudes oxide-free ideal product.
Claims (4)
1. the quantitative stove by inert gas heater and stalk one is with chewing.
2. control the quantitative stove of inert gas flow with chewing by PLC for one kind.
3. a used in aluminium alloy casting inert atmosphere is with chewing.
4. a product of casting alumina-free impurity is with chewing.
