Description
Technical field
The present invention relates to smelting field of nonferrous metal more particularly to a kind of liquid metal remote conveying delivery methods and its dress
It sets.
Background technique
The raw material of non-ferrous metal metallurgy is the associated minerals of various metals, contains the valuable goods and materials such as gold, silver, copper, zinc, tin.Fire
Method smelting process is exactly to utilize different metal element feature with different melting points, and various precious metals are gradually divided with liquid material
From, the process extracting and purify.Process mainly has pyrometallurgical smelting and hydrometallurgy.
The smelting process of country's non-ferrous metal is mainly that pyrogenic process is used to refine at present --- by the raw material liquid gold of molten state
Belong to liquid and be warmed to different temperatures section, generally 320 ° to 1100 °, certain metallic element is made to form compound by chemical reaction
And floats on liquid surface, then this mixture is pulled out from heating kettle to separate with liquid, liquid metal gradually becomes single
The pure state metal of ingredient.Just complete a pyrometallurgical smelting circulation.
The process of pyrometallurgical smelting was up to for more than 10 a hours, and what is carried out first is melting process, by impure more raw ingot
It is placed in pot and melts, liquid metal after purification is then transported to other melting pots.
The conveying of liquid metal has by the way of:
Canned conveying: liquid metal is squeezed into metal can with pump, then transports to specified melting pot with crane.If using melting
Pot across worker-house, across road, it is also necessary to use vehicles drive.This mode be used only in the limitation of restricted production distribution in old enterprise
Industry.Although canned conveying has the advantages that conveying distance is long, tank body needs to heat or has Insulation, to guarantee liquid
The temperature of metal is higher than freezing point or more, so there are high production cost for canned conveying, organization of production is many and diverse, more than security risk
Problem.
Ingot casting conveying: liquid metal is first cast to big spindles shape, then is transported to specified melting pot with haulage vehicle.This side
Formula has certain safety, and organization of production is also simpler than canned conveying, but ingot casting needs to heat again in next process
Dissolution also forms the problem of energy waste is serious, and activity time extends.
Runner conveying: liquid metal is squeezed into duct-like runner with pump, liquid metal is transported to specified melting along runner
Pot, usual conveying distance are suitable for short-distance and medium-distance and convey within 15 meters.Runner uses steel sectional material, there is round tube, rectangular tube
And channel steel etc..
The temperature of liquid metal is generally higher than 400 °, and into after runner, violent temperature change becomes profile
Shape, distortion lead to joint cracking leakage, need to be replaced frequently, be delayed the activity duration.
Canned conveying, there are one general character for runner conveying --- and bonding, liquid metal are very easy to contact in canister
Face forms crystallizing layer, and gradually heap height is blocking, so that blocking runner, makes liquid metal flows slow down or stop, cause liquid
Metal flow is out of control.Equally, the volume of tank body is also because the bonding of inner surface causes to scrap so that cavity volume is smaller and smaller.
Now, the development of smelting enterprise all develops to extensive, low consumption, inexpensive direction, the conveying of liquid metal
Mode becomes one of bottleneck of the market.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide, a kind of conveying is smooth, conveying distance is longer, design is simple
