Abstract
The invention discloses a kind of casting heat preservation rising head combustion adjuvant, formed by the component of following parts by weight: 15～25 parts of aluminium oxide powders, 6～10 parts, potassium permanganate, 8～12 parts, diatomite, 8～10 parts of magnesite soils, 6～8 parts of active carbons, 8～12 parts of activated manganese dioxides, 13～18 parts of charcoal powders, 8～12 parts of peromags, 6～8 parts of methenamines, 3～5 parts, active shale. Can ensure fully carrying out of oxidation reaction with the component of the present invention prepared combustion adjuvant of filling a prescription, liberated heat is maximum, combustion balance evenly, rising head is without obvious sintering hole, the programming rate of rising head is fast, can promote carrying out in advance of thermit reaction, significantly improve heating effect, the heat insulation effect of rising head, meet the feeding requirement of foundry goods, for the qualified of casting quality provides safeguard.
Description
Technical field
The present invention relates to metallurgical stone technical field, relate in particular to a kind of casting heat preservation rising head combustion adjuvant. .
Background technology
Rising head is that major function is row in order to avoid foundry goods to occur that defect is attached to the supplementary part of foundry goods top or sideGas, deslagging, molten steel feeding, for the casting quality that makes to produce is qualified, necessarily require rising head to have good heating, insulation effectReally, heat preservation rising head is one of effective ways of controlling casting quality preferably.
Heat preservation rising head is made up of various materials such as exothermic mixture, heat preserving agent and binding agents, in casting process, due toEmit gate material generation chemical reaction, make molten metal temperature increase wherein, thereby extend the setting time of molten metal in rising head,The anti-casting mold that flows back to, realizes feeding. Conventional exothermic riser exothermic mixture is thermite, just will make thermit reaction carry out smoothly, temperatureMust, up to more than 1383 DEG C, only rely on the liquid metal of cast, add hot riser and be not enough to make in the short period of time temperatureRaise, for this reason, need to add appropriate combustion adjuvant to promote temperature, impel thermit reaction to carry out fast.
Summary of the invention
The object of the present invention is to provide a kind of casting heat preservation rising head combustion adjuvant, can promote shifting to an earlier date of thermit reactionCarry out, significantly improve the overall heating efficiency of rising head.
To achieve these goals, technical scheme of the present invention is:
A kind of casting heat preservation rising head combustion adjuvant, is made up of the component of following parts by weight:
Aluminium oxide powder 15～25 potassium permanganate 6～10
Diatomite 8～12 magnesite soils 8～10
Active carbon 6～8 activated manganese dioxides 8～12
Charcoal powder 13～18 peromags 8～12
The active shale 3～5 of methenamine 6～8.
As the improvement to technique scheme, this combustion adjuvant is made up of the component of following parts by weight:
Aluminium oxide powder 20 potassium permanganate 8
Diatomite 10 magnesite soils 9
Active carbon 7 activated manganese dioxides 10
Charcoal powder 15 peromags 10
The active shale 4 of methenamine 7.
Compared with prior art, the invention has the beneficial effects as follows:
Through evidence, can ensure fully the entering of oxidation reaction of composition with the component of the present invention prepared combustion adjuvant of filling a prescriptionOK, liberated heat is maximum, and combustion balance evenly, rising head is without obvious sintering hole, and the programming rate of rising head is fast, can promote aluminothermyCarrying out in advance of reaction, significantly improves heating effect, the heat insulation effect of rising head, meets the feeding requirement of foundry goods, is casting qualityQualified providing safeguard.
Detailed description of the invention
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below in conjunction with concrete enforcementExample is further described the present invention, and apparently, the embodiment in the following describes is only that part of the present invention is implementedExample, for those of ordinary skill in the art, not paying under the prerequisite of creative work, can also implement according to theseExample obtains other embodiment.
Embodiment 1:
A kind of casting heat preservation rising head combustion adjuvant, is made up of the component of following parts by weight:
Aluminium oxide powder 15 potassium permanganate 8
Diatomite 10 magnesite soils 8
Active carbon 8 activated manganese dioxides 12
Charcoal powder 13 peromags 8
The active shale 3 of methenamine 6.
Embodiment 2:
A kind of casting heat preservation rising head combustion adjuvant, is made up of the component of following parts by weight:
Aluminium oxide powder 20 potassium permanganate 6
Diatomite 8 magnesite soils 9
Active carbon 7 activated manganese dioxides 10
Charcoal powder 18 peromags 12
The active shale 5 of methenamine 8.
A kind of casting heat preservation rising head combustion adjuvant, is made up of the component of following parts by weight:
Aluminium oxide powder 25 potassium permanganate 10
Diatomite 12 magnesite soils 10
Active carbon 6 activated manganese dioxides 8
