Description
Technical field
The utility model relates to a kind of casting mold, is specifically related to a kind of fused cast refractories casting mold.
Background technology
AZS production process to be cast in the sand mold of prior forming after the feed clarification of having melted in electric arc furnaces, after supercooling annealing insulation, adopt diamond abrasive tool to be processed into the process of goods.Casting rising head is the passage entering sand mold inside after feed liquid flows out from converter nose, domestic multiplex silica sand is made, but because cooling is too fast, can not play effective feeding effect, subsequent artefacts can pick out because of hardening being difficult to of solidifying of feed liquid by the process that spades chooses remove feeder.
When high temperature is poured into a mould, for preventing fused cast refractories depanning difficulty, usually using at mold bottom and smelting heelpiece, usually use at mold bottom and smelt heelpiece, prevent fused cast refractories and mould adhesion, play the effect of prevention depanning difficulty.But easily there is adhesion phenomenon bottom heelpiece upper surface and fused cast refractories and cause depanning difficulty, in addition, causing fused cast refractories to tie crackle because molten steel distributes rapidly at the heat of bottom, concentrating because of fused cast refractories bottom stress in forging process and easily cause the quality problems such as cracking.
Utility model content
The purpose of this utility model is to provide a kind of fused cast refractories casting mold, solve rising head cooling too fast can not effectively feeding, be difficult to pick out and in forging process, stress concentrates the quality problems such as the fused cast refractories end face cracking caused.
Fused cast refractories casting mold described in the utility model, comprise rising head body and die body, rising head body overcoat has an interlayer, and thickness of interlayer successively decreases from top to bottom, and interlayer inside is filled with insulation material, interlayer lower end arranges cameron core, rising head body lower end correspondence arranges die body, establishes mesh sheet between rising head body and die body, and die body inner chamber sets gradually fused cast refractories heelpiece and insulation heelpiece from bottom to top, be provided with through hole in the middle part of insulation heelpiece, die body is fixed on support.
Insulation heelpiece upper surface is horizontal by the circular arc of 100 degree ~ 110 degree.
Interlayer upper end thickness is 3 times of interlayer lower end thickness.
For the ease of picking out rising head, at interlayer arranged outside cross bar.
During use, be cast in die body by after the feed clarification of having melted in electric arc furnaces, insulation heelpiece upper surface is horizontal by the circular arc of 100 degree ~ 110 degree, and through hole is provided with in the middle part of insulation heelpiece, make to there will not be in casting process the fused cast refractories bottom crack that causes because of distributing rapidly of bottom molten steel heat and there will not be in forging process because bottom stress concentrates and cause cracking phenomena; Then, rising head is utilized to carry out feeding to foundry goods, rising head body overcoat has an interlayer, thickness of interlayer successively decreases from top to bottom, and interlayer inside is filled with insulation material, makes upper layer material liquid cooling slow, lower floor's feed liquid cooling is fast, can effectively feeding, in order to reach better feeding effect, interlayer upper end thickness is 3 times of interlayer lower end thickness; Interlayer lower end arranges cameron core, establishes mesh sheet between rising head body and die body, reduces the contact area of rising head and die body, is convenient to remove rising head; Preferably at interlayer arranged outside cross bar, suspension hook is hung on cross bar and can pick out rising head, save manual operation.
In sum, the utility model has the following advantages:
(1) the utility model rising head body overcoat has an interlayer, and thickness of interlayer successively decreases from top to bottom, and interlayer inside is filled with insulation material, and upper layer material liquid cooling is slow, and lower floor's feed liquid cooling is fast, can effectively feeding; Interlayer lower end arranges cameron core, establishes mesh sheet between rising head body and die body, reduces the contact area of rising head and die body, is convenient to remove rising head.
(2) insulation heelpiece upper surface of the present utility model becomes globoidal structure from planar structure, the fused cast refractories bottom crack that fused cast refractories be there will not be in casting process cause because of distributing rapidly of bottom molten steel heat and there will not be in forging process because bottom stress concentrates and cause cracking phenomena, improves out fused cast refractories quality effectively.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described further.
Embodiment
As shown in Figure 1, comprise rising head body 1 and die body 6, rising head body 1 overcoat has an interlayer 2, and interlayer 2 thickness successively decreases from top to bottom, and interlayer 2 inside is filled with insulation material 3, interlayer 2 lower end arranges cameron core 4, rising head body 1 lower end correspondence arranges die body 6, establishes mesh sheet 5 between rising head body 1 and die body 6, and die body 6 inner chamber sets gradually fused cast refractories heelpiece 7 and insulation heelpiece 8 from bottom to top, be provided with through hole 9 in the middle part of insulation heelpiece 8, die body 6 is fixing over the mount 10.
During use, to be cast in die body 6 after the feed clarification of having melted in electric arc furnaces, insulation heelpiece 8 upper surface is horizontal by the circular arc of 105 degree, and through hole 9 is provided with in the middle part of insulation heelpiece 8, make to there will not be in casting process the fused cast refractories bottom crack that causes because of distributing rapidly of bottom feed liquid heat and there will not be in forging process because bottom stress concentrates and cause cracking phenomena; Then, utilize rising head to carry out feeding to foundry goods, rising head body 1 overcoat has an interlayer 2, interlayer 2 thickness successively decreases from top to bottom, and interlayer 2 inside is filled with insulation material 3, when preferred interlayer 2 upper end thickness is 3 times of lower end thickness, better heat preservation, make upper layer material liquid cooling slow, lower floor's feed liquid cooling is fast, can effectively feeding, interlayer 2 lower end arranges cameron core 4, establish mesh sheet 5 between rising head body 1 and die body 6, reduce the contact area of rising head and die body 6, be convenient to the removing of rising head.
