Abstract

The utility model discloses a split riser, which consists of a riser body and a riser edge. A cavity is formed in the center of the riser body. The riser edge is disc-shaped. A connecting ring is arranged on the outer peripheral surface of the lower end of the riser body. A plurality of opposite bolt holes are uniformly formed in the peripheral surfaces of the connecting ring and the riser edge. The connecting ring is connected with the riser edge through bolts. The split riser is simple in structure and easy to produce and store, the occupation of too much money for the storage of the split riser is avoided, and a plurality of problems during the use of an integral riser are solved.

Description

A kind of split type rising head

Technical field

The utility model belongs to casting technology field, relates to the architecture advances that ingot steel casting is used rising head.

Background technology

Metallurgy industry and Heavy duty maching industry are all being produced a large amount of steel ingots every year, steel ingot is in the casting solidification process, steel ingot rising head lower surface is for a long time under molten steel direct effect more than 1500 ℃, it is serious to cause the rising head lower surface to ablate, form crackle or distortion, as continue to use, the steel ingot of producing solidify with knockout course in, the ingot body very easily cracks defective and causes the steel ingot waste product, general rising head uses 20～30 times, namely can not satisfy instructions for use owing to the rising head lower surface, and whole rising head is scrapped, the rising head consumption is increased, longer owing to the rising head production cycle in addition, each factory carries out smoothly in order to guarantee to produce, and how can lay in some various ingot shape rising heads, so just causes fund to overstock.

The utility model content

The utility model provides a kind of split type rising head for addressing the above problem, change whole rising head into Split type structure, be divided into upper and lower two parts, two parts connect with bolt, the lower surface of the whole rising head of lower Partial Replacement, simple in structure, be easy to produce and deposit, lay in some and can not take too much fund, solved the problems in the whole rising head use.

The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is:

A kind of split type rising head, by emitting body and emitting along forming, emit the body center to be provided with a cavity, emit along being plate-like, emit the outer circumference surface of body lower end to be provided with connecting ring, evenly be provided with a plurality of corresponding bolts hole on the periphery of connecting ring with on the periphery that emits the edge, connecting ring is bolted with emitting the edge.

The surface smoothness of connecting ring described in the utility model lower surface is 12.5 with emitting the upper surface on edge and the surface smoothness of lower surface.

Spacing between two adjacent bolt hole II described in the utility model is 300mm～400mm.

The edge that emits described in the utility model is 60mm～90mm with emitting the thickness of body lower end connecting ring.

It is described in the utility model that to emit the vertical section of body cavity be trapezoidal.

The cross section of body cavity that emits described in the utility model is for circular or oval.

The beneficial effects of the utility model are: the utility model changes whole rising head into Split type structure, be divided into and emit body and emit along two parts, two parts connect with bolt, emit along the lower surface that replaces whole rising head, if emit along distortion or the crackle of ablating, in time change and emit the edge, but and emit the body iterative cycles to use, reached and reduced the purpose that rising head consumes.Other emits along simple in structure, is easy to produce deposit, and lays in some and can not take too much fund, reduces industrial cost.

Fig. 1 is the sectional structure schematic diagram that emits body of the present utility model;

Fig. 2 is the sectional structure schematic diagram that emits the edge of the present utility model;

Fig. 3 is the body and emitting along the assembly structure schematic diagram of emitting of the present utility model;

Among the figure: 1, emit body, 101, connecting ring, 2, emit the edge, 201, bolt hole.

The specific embodiment

As shown in the figure, a kind of split type rising head, form by emitting body 1 and emitting along 2, emit body 1 center to be provided with a cavity, emit along 2 for plate-like, emit the outer circumference surface of body 1 lower end to be provided with connecting ring 101, on the periphery of connecting ring 101 with emit along evenly being provided with a plurality of corresponding bolts hole 201 on 2 the periphery, connecting ring 101 is bolted with emitting along 2.

It is described that to emit the vertical section of body 1 cavity be trapezoidal.

The described cross section of body 1 cavity that emits is for circular or oval.

Improve emitting body 1, emit along 2 and be the same material after the design, be generally HT21-40.

Described connecting ring is the flange that emits on the body 1.

Be worked into fineness 12.5 for guaranteeing assembling and cast requirement, emitting the lower surface of body 1 and emit along 2 upper and lower end face.

Emit body 1 and emit to require to join to bore along 2 bolt hole and finish, guarantee that bolt hole I and bolt hole II aim at.

Emit body 1 in avoiding using, emit affect along 2 distortion and use next time, number of bolt hole is suitably more, general two adjacent pitch of bolts 300mm～400mm, evenly distribution;

Relatively bolt is simultaneously fastening in twos during assembling, must not once tighten when fastening, should make emit body 1, emit along 2 circumferencial direction stressed evenly after, carry out again fastening.

After whole rising head is modified into the split rising head, emit body 1 can be recycled, emit along 2 and ablate distortion seriously, replacing is emitted along 2, emits body 1 can continue to use, and emits along 2 weight only to be about 16～18% of whole rising head weight, rising head consumption reduces greatly, and deposit rising head occupied fund greatly reduces.
