Abstract
An application of diatomite as demoulding agent includes such steps as pulverizing diatomite, baking, calcining at 600-900 deg.C, purifying and spraying or applying the powder on the inner surface of casing mould. Its advantages are high chemical stability, easy demoulding and high surface quality of casting.
Description
Technical field:
The present invention relates to diatomaceous purposes, relate in particular to diatomite in application as the centrifugal casting releasing agent.
Background technology:
At present, foundry enterprise generally adopts lead powder as the centrifugal casting releasing agent, because the tack of lead powder is not strong, is easy to generate scab, influences the qualification rate of product, and lead powder is toxic to human body in addition.Diatomaceous Main Ingredients and Appearance is non-quartziferous silica, and adhesive ability is strong, and chemical property is highly stable, and 1200 ℃ of roastings can not change its character, and do not have toxicity.
Summary of the invention:
The technical problem to be solved in the present invention is to disclose a kind of diatomaceous new purposes, promptly as the application of centrifugal casting releasing agent.
The present invention relates to the application of diatomite as the centrifugal casting releasing agent.
Diatomite is made powdery, oven dry, roasting under 600-900 ℃ of condition, purification make diatomite moisture content≤0.1%, granularity≤20 μ m, and 95% above grain graininess≤10 μ m.During use, that its spraying or brush is at the inner surface of mold, identical with the using method of lead powder.
On the inner surface attached to mold, chemical property is stable effectively for releasing agent of the present invention, forms effective separation layer between molten iron and mold, and the foundry goods demoulding is easy, the cast article blemish that can avoid sticking sand to cause, and human body do not had toxic side effect.
The specific embodiment:
Diatomite is made powdery, oven dry, roasting under 800 ℃ of conditions, purification make diatomite moisture content≤0.1%, granularity≤20 μ m, and 95% above grain graininess≤10 μ m.During use, it is sprayed on the inner surface of mold.
