Integral running castings mold device of large-sized steel ingot clamp

Abstract

The invention discloses a large steel ingot-clamper integral casting mould and belongs to the technology field of ingot mould in steel melting. A lower chassis seat is horizontally arranged on the ground, an upper chassis protective ring is arranged on the lower chassis seat, a multi-layer firebrick cushion is built inside the upper chassis protective ring, a sand lining is covered on the multi-layer firebrick cushion, a ring-shaped firebrick wall is built on the sand lining, a vertical resin-bonded sand lining is arranged in the inner ring of the ring-shaped firebrick wall, a steel ring is bonded with the vertical resin-bonded sand lining, a round steel plate mat is arranged inside the steel ring in a way that the bottom thereof is attached to the sand lining, a chassis cover is arranged on the top of the ring-shaped firebrick wall, a ring-shaped steel plate mat is arranged inside the chassis cover, a steel ingot mould is arranged on the upper chassis protective ring, a heightening ring is arranged on the steel ingot mould, and a heat-insulating cap is arranged on the heightening ring. The casting mould solves the problem that the upward shift of steel ingot depositions may affect the quality of steel ingot. The clamper and the steel ingot are integrally cast so as to prevent the clamper from stripping or loosening off the steel ingot during the following forging procedures.

Description

technical field [0001] The invention relates to a large-scale steel ingot tong handle integral casting mold device, which belongs to the technical field of steelmaking steel ingot molds. Background technique [0002] At present, with the large-scale development of power stations and steel rolling equipment, the weight of a single piece of shaft forgings such as rotors and backup rolls is also increasing, and the weight of a single piece of steel ingot is also increasing. The forging of large steel ingots has become a problem. The general method of forging a large steel ingot is to first forge the tail of the steel ingot into an easy-to-clamp tongs, and then clamp the steel ingot with the tongs to turn over the forging mold. The disadvantage is that the firing time of the steel ingot is long, the weight of the steel ingot is large, and the cost is high; The method used abroad to solve the problem of overweight forging shaft forging equipment was only found in a Japanese compa...

Problems solved by technology

[0002] At present, with the large-scale development of power stations and steel rolling equipment, the weight of a single piece of shaft forgings such as rotors and backup rolls is also increasing, and the weight of a single piece of steel ingot is also increasing. The forging of large steel ingots has become a problem. The general method of forging a large steel ingot is to first forge the tail of the steel ingot into an easy-to-clamp tongs, and then clamp the steel ingot with the tongs to turn over the forging mold. The disadvantage is that the firing time of the steel ingot is long, the weight of the steel ingot is large, and the cost is high; The method used abroad to solve the problem of overweight forging shaft forging equipment was only found in a Japanese company, but they used the pre-embedded casting method of tongs, that is, forging a steel ingot in advance to form a tongs with a size that meets the forging requirements. It is buried in the chassis, and the upper end is higher than the upper plane of the chassis. When the steel ingot is being poured, the molten steel will wrap the upper end of the tongs so that they are integrated with the steel ingot, creating favorable conditions for the subsequent forging, which is conducive to the smooth removal of the tongs from the chassis. The size error of the tong handle is small; the disadvantage is: the steel ingot deposit pile moves up to the ingot body, which seriously affects the quality of the steel ingot; the tong handle can only be wrapped by the steel ingot, and cannot be integrated with the steel ingot. Falling off or loosening from the ingot, the subsequent forging cannot be continued; steel ingots must be forged and processed into tongs that meet the forging size requirements in advance, which not only wastes a lot of production costs, but also brings difficulties to production organization; large steel ingot tongs cast the whole It is still blank in China, and no reports on this aspect have been found so far
