The invention aims to provide a novel steel ingot feeder head, a steel ingot mould and a casting method by utilizing the steel ingot mould, which improve the utilization rate of steel ingots and reduce the phenomenon of box opening and ring cracking.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a novel steel ingot rising head, includes the smooth and slick transition part of the outside extension of the vertical cylinder part of upper end and lower extreme, and vertical cylinder part center is provided with the cylinder space, and smooth and slick transition part is inside and outside the toper skirt-shaped structure of taking the arris.
The technical scheme of the invention is further improved as follows: an interlayer is arranged in the outer wall of the vertical cylinder part, and heat insulation materials are filled in the interlayer.
A steel ingot mould comprises the novel steel ingot feeder head as claimed in claim 1-2, wherein an ingot body is arranged at the lower end of the feeder head, a convex edge is arranged outside the ingot body, and the convex edge outside the ingot body corresponds to the edge of the smooth transition part of the feeder head.
A pouring method using a steel ingot mold comprises the following steps:
step 1) determining the height of a heat insulation plate in a riser, and inserting and hanging the heat insulation plate in the vertical part of the riser;
step 2) aligning and combining the ingot body and the riser, integrally placing the ingot body and the riser into a vacuum chamber, and marking the casting height of the riser according to the size of the ingot;
step 3), carrying out vacuum pouring until the pouring height of the marked riser is reached, and stopping pouring;
and 4) during the box opening operation, firstly, lifting away from a dead head part, secondly, integrally lifting the steel ingot and the steel ingot mould body to a box opening site, taking out the steel ingot after turning, and transferring to a heat treatment furnace for annealing or slow cooling treatment.
Due to the adoption of the technical scheme, the invention has the technical progress that:
the invention aims to provide a novel steel ingot feeder head, a steel ingot mould and a pouring method thereof, which can improve the utilization rate of steel ingots and reduce the phenomenon of box opening and ring cracking. The steel ingot feeder head is provided with the smooth transition part, edges of the smooth transition part are opposite to edges arranged outside the ingot body, the feeder head is not deviated when being closed, the problem of opening and ring-cracking of the steel ingot is solved, and the steel ingot feeder head is beneficial to subsequent forging production. An interlayer is arranged in the outer wall of the vertical cylindrical part of the steel ingot feeder head and filled with heat insulation materials, so that the heat insulation effect of the feeder head is improved.
