Abstract
The most air-cooled method of a kind of pig iron casting, relates to pig iron casting technology field, it is characterised in that: include preliminary evacuation, place chiller, carry out casting, carry out wind cooling temperature lowering, carry out Temperature fall.The inventive method is reasonable, easy to operate, cooling is quick.
Description
Technical field:
The present invention relates to pig iron casting technology field, be specifically related to the most air-cooled side of a kind of pig iron casting
Method.
Background technology:
The pig iron is the iron-carbon alloy that phosphorus content is more than 2%, commercial iron phosphorus content typically at 2.11%--4.3%,
And containing elements such as C, Si, Mn, S, P, be to use iron ore through the product of blast furnace process.According to carbon in the pig iron
The difference of existing forms, can be divided into again conversion pig, foundry iron and spheroidal graphite cast-iron etc. several.
And during the pig iron casts, carry out foundry goods by evaporative pattern, and come by the way of evacuation
Natural cooling, this is the most common method, but such method has several drawback, and one when being cooling
Between long, efficiency is low, two is foundry goods is easily subject to extruding during cooling and causes trickle deformation,
So just may cannot use on the most accurate instrument, reform into waste product, thus easily caused
Loss greatly.
Summary of the invention:
The technical problem to be solved is to overcome existing technological deficiency to provide a kind of method to close
Reason, easy to operate, the most air-cooled method of quick a kind of pig iron of lowering the temperature casting.
The technical problem to be solved uses following technical scheme to realize:
A kind of the most air-cooled method of pig iron casting, it is characterised in that: comprise the following steps,
Step one, preliminary evacuation: evaporative pattern is placed in the placing box being stacked with sand, places
Afterwards placing box is carried out evacuation；
Step 2, placement chiller: before vacuum extraction cooling tube is placed on around evaporative pattern, all
Even placement；
Step 3, cast: the high temperature liquid iron just melted is transported in evaporative pattern by conveying pipe,
Evacuation is stopped the when of conveying；
Step 4, carry out wind cooling temperature lowering: after hot metal transport is complete, filled in cooling tube by blower fan immediately
Entering air, carry out evacuation while being filled with air, the speed of evacuation and blower fan are filled with the speed of air
Identical；
Step 5, carry out Temperature fall: wind cooling temperature lowering is carried out 15-20 minute, then stop blower fan to cooling
Pipe is filled with air, is only lowered the temperature by evacuation；
Described cooling tube is that alfer material is made, for " L " shape or " J " shape；
Shorter one section of described cooling tube is placed on outside placing box, and is provided with opening；Cooling tube is longer
One section on be uniformly placed with intensive aperture, and outside is enclosed with the separation net that two-layer iron wire is made.
The Process that the invention have the benefit that arrangement is the circulation facilitating air, and is provided with isolation
Net is to prevent sand from entering in cooling tube, the identical evacuation of through-rate with send air, material is thus formed
The Rapid Circulation of one air, and the temperature of the wind sent by blower fan is all without the highest, so in cooling
When the most very convenient, and after air-cooled, be still provided with Temperature fall be to ensure that material can be fitted
Answer extraneous air, it is ensured that quality.The inventive method is reasonable, easy to operate, cooling is quick.
Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be readily apparent from
Solve, the present invention is further elucidated below.
A kind of the most air-cooled method of pig iron casting, it is characterised in that: comprise the following steps,
Step one, preliminary evacuation: evaporative pattern is placed in the placing box being stacked with sand, places
Afterwards placing box is carried out evacuation；
Step 2, placement chiller: before vacuum extraction cooling tube is placed on around evaporative pattern, all
Even placement；
Step 3, cast: the high temperature liquid iron just melted is transported in evaporative pattern by conveying pipe,
Evacuation is stopped the when of conveying；
Step 4, carry out wind cooling temperature lowering: after hot metal transport is complete, filled in cooling tube by blower fan immediately
Entering air, carry out evacuation while being filled with air, the speed of evacuation and blower fan are filled with the speed of air
Identical；
Step 5, carry out Temperature fall: wind cooling temperature lowering is carried out 15-20 minute, then stop blower fan to cooling
Pipe is filled with air, is only lowered the temperature by evacuation；
Described cooling tube is that alfer material is made, for " L " shape or " J " shape；
Shorter one section of described cooling tube is placed on outside placing box, and is provided with opening；Cooling tube is longer
One section on be uniformly placed with intensive aperture, and outside is enclosed with the separation net that two-layer iron wire is made.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, the present invention is not restricted to the described embodiments, above-described embodiment and explanation
The principle that the present invention is simply described described in book, without departing from the spirit and scope of the present invention,
The present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention model
In enclosing.Claimed scope is defined by appending claims and equivalent thereof.
