Abstract
The utility model is related to a kind of metals to be molded into slow setting hot top; including being molded into ontology; it is characterized in that being equipped with the hot top of electrified heating device above ontology in described being molded into; the hot top mainly by refractory material cap body, the heater being arranged in refractory material cap body, be arranged refractory material cap body top power protection sleeve and be arranged in refractory material cap body both sides, and be molded into bodies top overlapped that holder is formed.The utility model has the advantages that：Metal is molded into the insertion of slow setting hot top and is molded into top, can effectively extend the setting time of molten metal, play slow setting, heat-insulated and insulation effect, cap mouth rejection rate can be made to reduce 7% or so, improve recovery rate of iron, there is apparent economic benefit.
Description
Technical field
The utility model belongs to metal and is molded into hot top technical field, more particularly to a kind of metal is molded into slow setting hot top.
Background technology
In pour steel since upper steel liquid cooling is too fast, the timely of top molten steel cannot be obtained when lower part being caused to cool down
Supplement, produces loose inside deeper shrinkage cavity and steel ingot, and there are the deficiencies of Large Inclusions.In order to solve above-mentioned ask
Topic, the structure that existing metal is molded into hot top are to install hot top additional on punching block top, and upper interior accent has heat-insulating shield, and the purpose is to prolong
The shortcomings that long metal freezing time, this structure is that cap mouth is too big, and heat insulation effect is bad, is molded into the rejection rate of cap mouth on 10% left side
It is right.
Invention content
The purpose of this utility model is to provide a kind of temperature that can keep top molten steel after being cast, ensure field trash
It further fully floats and removes, postpone the solidification of molten steel time, the metal for improving yield rate is molded into slow setting hot top.
It being molded into slow setting hot top according to a kind of metal of the utility model, a kind of 1. metals are molded into slow setting hot top, including
It is molded into ontology, it is characterised in that the hot top of electrified heating device, the hot top master are equipped with above ontology in described being molded into
It to be protected by refractory material cap body, the heater being arranged in refractory material cap body, the power supply being arranged on refractory material cap body top
Sheath and be arranged in refractory material cap body both sides, and be molded into bodies top overlapped that holder is formed.
Further, the power protection sleeve by metal jacket pipe, be arranged on the inside of metal jacket pipe with cooling water
Inner sleeve and what is be arranged on the inside of inner sleeve formed with heater connecting wire, the conducting wire is connected with power supply.
Further, it is equipped with thermal insulation layer in described being molded on the inside of body upper part.
Further, hanging ring is equipped on the holder.
Further, the thermal insulation layer is aluminum fire resistant materials, silica refractory or magnesia refractories.
The utility model has the advantages that：Metal is molded into the insertion of slow setting hot top and is molded into top, can effectively extend metal
The setting time of liquid plays slow setting, heat-insulated and insulation effect, and cap mouth rejection rate can be made to reduce 7% or so, improves metal receipts
Yield has apparent economic benefit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of metal of the utility model is molded into slow setting hot top, including it is molded into ontology 1, it is characterised in that
The hot top of electrified heating device is equipped with above ontology 1 in described be molded into, the hot top mainly by refractory material cap body 7,
The heater 6 that is arranged in refractory material cap body 7, be arranged 7 top of refractory material cap body power protection sleeve and be arranged resistance to
Fiery 7 both sides of material cap body, and be molded into the top of ontology 1 overlapped that holder 4 is formed.The heater 6 may be used electricity and add
Hot device, heating rod, infrared heater or induction heater.With realize extend molten metal setting time, play slow setting, it is heat-insulated and
Insulation effect.
Further, the power protection sleeve is cooled down by metal jacket pipe 10, the band being arranged in 10 inside of metal jacket pipe
The inner sleeve 9 of water and being formed with 6 connecting wire 8 of heater in the inside of inner sleeve 9, the conducting wire 8 and power supply phase are set
Connection.The power protection sleeve of this structure can ensure that power safety works.
Further, it is equipped with thermal insulation layer 3 in 1 upper inner of ontology that is molded into.The solidification of molten metal can effectively be extended
Time plays slow setting, heat-insulated and insulation effect.
Further, it is equipped with hanging ring 5 on the holder 4, is easy to lift.
Further, the thermal insulation layer is aluminum fire resistant materials, silica refractory or magnesia refractories.For extending
The setting time of molten metal plays good booster action.2 be molten metal in figure.
It is molded into heat preservation suitable for various molten metals, cap mouth rejection rate can be made to reduce 7% or so, metal is improved and receive
Rate has apparent economic benefit.
