Demonstrate,prove feeding of the metal to casting heat energy-saving position in riser buss.
However for the molten metal in riser buss, the approach of external dissipated heat mainly has thermal convection, heat transfer
With three kinds of approach of heat radiation.Big portion for the open riser of straight barrel type, due to leading directly to atmosphere at the top of riser buss, in riser buss
Divide heat that can largely lose by the heat radiation to air.Thus directly affect the thermal insulation property and most of straight barrel type riser
Whole practical feeding effect, therefore the feeding efficiency of conventional straight tube open riser only has 10-15% or so, the major part in riser buss
Molten metal can not play due feeding effect due to solidifying in advance.
Utility model content
The purpose of the utility model is to overcome it is above-mentioned there are deficiency, one kind is provided and is rest directly upon straight tube open riser top
The heating cover of casting head in portion enables straight barrel type open riser to cooperate this heat loss for emitting lid and effectively avoiding top, improves
The feeding efficiency of riser inner metal liquid is to 20-30%.
To achieve the goals above, technical solution used by the utility model is as follows:
The utility model provides a kind of straight barrel type open riser heating cover of casting head comprising emit lid ontology, described
It is provided at least one venthole and relief groove on body, is provided with bonding region on the ontology, is provided in the bonding region
Concave-convex bonding lines, the ontology have included at least heating layer and insulating layer, and the relief groove is protected with ontology coupling part
Warm layer covering.
According to a kind of this practical new straight barrel type open riser heating cover of casting head, further technical solution is:
The venthole is one or two.
According to a kind of this practical new straight barrel type open riser heating cover of casting head, further technical solution is:
The diameter of the venthole is identical as the thickness for emitting lid ontology.
According to a kind of this practical new straight barrel type open riser heating cover of casting head, further technical solution is:
The concave-convex amplitude of the bonding lines is less than 1mm.
According to a kind of this practical new straight barrel type open riser heating cover of casting head, further technical solution is:
The width of the bonding region and the wall thickness of riser are identical.
According to a kind of this practical new straight barrel type open riser heating cover of casting head, further technical solution is:
The insulating layer is between heating layer and body outer wall, and the heating layer and relief groove are in the ipsilateral of ontology.
The utility model has the advantage that compared with prior art
1, it is simple, easy to use originally to emit port cover structure, lid will be emitted in actual use by, which only needing, is placed in original straight tube
At the top of type open riser, the two is adhesively fixed.
2, it originally emits lid and has two kinds of characteristics of heat preservation and fever, can effectively reduce the heat between riser buss inner metal liquid and atmosphere
Radiation；It is also equipped with hair thermal property simultaneously, the molten metal in riser buss can additionally be heated.
3, the heating cover of casting head do not change it is original emit mouth-shaped in the case where, by increase have heat retaining and exothermal performance
The feeding efficiency of riser inner metal liquid greatly improved in top cover, 20%-30% has been promoted to by original 10%-15%, so that feeding
Efficiency is double.
4, the utility model compares existing exothermic riser, can be according to practical situation as an individual accessory
Collocation uses, to save production cost, improves efficiency.
