The invention relates to a heating and heat-insulating filling liner, which is mainly prepared from the following components in parts by mass: 5 to 25 parts of metal aluminum powder, 5 to 20 parts of ferric oxide, 20 to 50 parts of aluminum oxide, 5 to 15 parts of silicon dioxide, and 5 to 15 parts of resin. A preparation method comprises the steps of a, compounding; b, mixing raw materials; c, adopting the resin as a binding material, and mixing the resin with the raw materials to prepare a binding agent; d, carrying out suction filtration and compression molding; e, drying for 8 to 20 hours within the temperature range from 50 DEG C to 1500 DEG C; f, sintering for 10 hours within the temperature range from 150 DEG C to 200 DEG C. During mold casting, the heating filling liner is placed on an inner wall of a mold cavity, the temperature of molten steel is mostly ranged from 1400 DEG C to 1600 DEG C, aluminate powder and ferric oxide are reacted to generate iron and aluminum oxide, a lot of heat is released, alpha-phase aluminum oxide used as a heat-insulating material is applied widely, and the heat conductivity coefficient of the silicon dioxide is 0.27W/cm.K, so that the heating filling liner has a certain heat retaining property; the filling liner provided by the invention can effectively help feed a casting so as to obtain a complete casting without the need for cutting, the casting is complete, energy conservation and environment protection are realized, and the economic cost is reduced.
Description
Technical field
The invention belongs to casting technology field, and in particular to a kind of heat preservation mends lining.
Background technology
Cast in past production, defect occur to avoid casting, plane side sets molten steel and mends lining generally on mold,
Casting feeds metal when being formed, and prevents shrinkage cavity and porosity, and the Main Function for mending lining is feeding, special in special casting
It is not using most commonly seen in the larger casting of depth ratio.During casting, by the hydraulically full metal of mold cavity, casting cooling shaping
, it is necessary to be sliced off lining is mended with gas cutting after cleaning, but useless work when so both giving up, substantial amounts of molten steel material is wasted again, in cutting
Also easily casting is damaged when mending lining, while also not environmentally.
The content of the invention
In order to solve problem above, mended it is an object of the invention to provide a kind of heat preservation and served as a contrast, be used to being cast in mold
Metal liquid in die cavity provides temperature, reduces its setting rate, improves riser feeding rate.
The technical scheme is that：A kind of heat preservation mends lining, it is characterised in that its composition mainly includes metallic aluminium
Powder, iron oxide, aluminum oxide, silica, its mass fraction are respectively：Metallic aluminium powder is 5-25, and iron oxide is 5-20, oxidation
Aluminium is 20-50, and silica is 5-15, resin 5-15.
Its preparation method is comprised the following steps：A. dispensing, b. by mixing raw materials, c. with resin as binding material, with raw material
It is mixed and made into bonding agent, d. suction strainer compression moldings, e. dries 8-20 hours in 50 ° of -150 ° of temperature ranges, f.150 ° -200 °
Sintering 10 hours in temperature range.
Described heat preservation is mended lining and is embedded on mold cavity inwall.
Relative to prior art, beneficial effects of the present invention are：A kind of heat preservation that the present invention is provided mends lining and prepares letter
It is single, it is easy to use, in casting mold, lining is mended in heating and is put on the inwall of mold cavity, in cast, because liquid steel temperature is most
At 1400 ° -1600 °, such temperature conditionss issue aluminium powder and the iron oxide vulcanized in lining occur chemical reaction generation iron and
Aluminum oxide, and substantial amounts of heat is released, aluminum oxide can undergo phase transition under 900 ° of temperature conditionss, be transformed into alpha-type aluminum oxide, α phases
Aluminum oxide is the far-infrared emission material of excellent performance, is widely used as far infrared transmission and insulation material, silica
Thermal conductivity factor is 0.27W/cmK, with certain heat insulating ability, therefore, the benefit lining that the present invention is provided can play good heating
Heat insulation effect, can effectively help feeding a casting, obtain complete casting, be not required to cutting, and casting is complete, and energy-conserving and environment-protective also reduce warp
Ji cost.
