Abstract
The utility model discloses a mould casting structure of flaw detection steel grade. The mould casting structure of the flaw detection steel grade comprises a heat preservation cap, insulation boards and a steel ingot mould, wherein the insulation boards are circularly arranged on the upper part of the inner wall of the steel ingot mould; and the upper edges of the insulation boards are aligned with the upper edge of the steel ingot mould. The material below a riser line of a steel ingot produced by the mould casting structure of the flaw detection steel grade is quite compact, so that the problem of unqualified flaw detection caused by looseness after the rolling of a thick board is effectively solved, and the yield is improved.
Description
Technical field
The utility model relates to metallurgical technology field, is specifically related to a kind of die casting structure of heavy section crack detection steel grade.
Background technology
At present large substance, large thickness, require the steel plate of flaw detection, generally all adopt steel ingot-forgings or Electro Slag Remelting Steel production, complex procedures, high expensive, and adopt steel ingot directly to roll plate production, then because ingot head is seriously loose, the steel plate inspection qualification rate after rolling is extremely low.Metallurgy industry takes to improve Cleanliness of Molten Steel mostly, such as reducing foreign substance in molten steel content, increase vacuum processing time, argon gas maintenance cast etc., or reinforcement hot top cap mouth heat preservation technology, as adding exothermic mixture, heating board etc. at the cap mouth, or employing water-cooled steel ingot mould, die casting such as gently depresses at the technology, improves the flaw detection qualification rate of steel plate.But cost is increased, and DeGrain, especially for steel plate thickness greater than 180mm, other steel grade of flaw detection level more than the GBIII level, still without effective solution.
Summary of the invention
The purpose of this utility model is to provide a kind of die casting structure of the steel grade of detecting a flaw, to improve the flaw detection qualification rate of heavy section crack detection steel grade.
The utility model is achieved through the following technical solutions:
The die casting structure of flaw detection steel grade comprises hot top, heat-insulating shield and ingot mould, and described heat-insulating shield annular is arranged at the ingot mould upper inside wall, and the upper edge of described heat-insulating shield is upper along concordant with ingot mould.
Described ingot mould is ironcasting.
Described hot top inwall is provided with heat-insulation layer.
The utility model arranges heat-insulating shield around the ingot mould upper inside wall, be provided with heat-insulation layer at the hot top inwall, then utilize the interior molten steel of mould to carry out feeding, cap mouth heat insulation effect is good, simple and the successful of shrinkage compensation method, material is very fine and close under the ingot head opening line that employing the utility model is produced, and has effectively solved slab and has rolled the rear defective problem of flaw detection because loosening and causing, and has improved lumber recovery.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Sequence number among the figure: 1, hot top, 2, heat-insulating shield, 3, ingot mould.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but do not consist of any restriction of the present utility model.
Referring to shown in Figure 1, a kind of die casting structure of the steel grade of detecting a flaw, comprise hot top 1, heat-insulating shield 2 and ingot mould 3, described heat-insulating shield 2 annulars are arranged at ingot mould 3 upper inside wall, the upper edge of described heat-insulating shield 2 is upper along concordant with ingot mould 3, described hot top 1 inwall is provided with heat-insulation layer, and described ingot mould 3 is ironcasting.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
