Abstract

The invention belongs to a mould applied in an alloy smelting pouring process, and particularly relates to a molding receiving mould for an alloy continuous casting machine. The receiving mould comprises a mould main body and casting pit grooves uniformly distributed in the mould main body; the mould main body is of a rectangular structure, the upper plane of the front portion of the mould main body and the upper plane of the back portion of the mould main body are provided with a front lap-joint portion and a back lap-joint portion respectively, the middles of the two sides of the mould main body are provided with fixing lugs respectively, fixing bolt holes are formed in the fixing lugs, and diagonal reinforcing ribs are made at the joints of the fixing lugs and the mould main body. The receiving mould has the following advantages that the materials are low in cost and are easily obtained, the high temperature and molten steel impact and corrosion can be resisted, the structure is simple, demoulding can be perfectly achieved after detail treatment, the demoulding rate exceeds 99%, and it is guaranteed that the casting machine can continuously operate.

Description

Continuous casting machine is with accepting mould

Technical field:

The invention belongs to the mould that alloy smelting cast operation uses, water continuously particularly to alloy Mould is accepted in casting machine molding.

Background technology:

In the casting machine equipment that metallurgy industry uses, casting die used is most important portion Part, because casting die is the important container of carrying molten steel, the temperature of molten steel is the highest, if watered Casting mould can not have the multifrequency natures such as the most corrosion-resistant, high temperature resistant, and the most reasonably ties Structure, will result in die life short, stripping result difference etc. problem, if can not the demoulding smoothly, Casting machine work efficiency can be caused to reduce, even lead to security incident, some mould was using It also occur that the problem of molten steel leakage in journey, causing the waste of material resources, the molten steel of leakage is cold But easily adjacent molds is sticked together after, again affects die life, increase and safeguard Cost.

Summary of the invention:

Therefore, it is necessary to offer one is simple and reasonable, high temperature resistant, corrosion-resistant, intensity is good, Can use for a long time and the mould of the energy demoulding smoothly.

Continuous casting machine is with accepting mould, including die main body and being evenly distributed on die main body Casting pit；Die main body is rectangle structure, the upper plane of the front and rear portions of die main body It is shaped with front clinch and rear clinch, fixing ear is installed in the middle part of the dual-side of die main body, Gu Determining to be shaped with on ear fixed bolt hole, the junction of fixing ear and die main body is shaped with oblique pull shape and strengthens Muscle.

Preferably, described casting pit is truncated rectangular pyramids shape, the bottom surface of casting pit and casting pit Opening be all square, casting pit base a length of 15～25mm, casting pit top The length of side is 70～80mm, and the degree of depth of casting pit is 32～36mm；Truncated rectangular pyramids shape water foundry pit Groove can allow releasing agent uniformly spray in its surface, and the casting pit under this ratio was both Client's requirement to product can be met, can guarantee that again the more preferable demoulding, enable casting machine continuous Work, improves production efficiency.

Preferably, the described bottom surface of casting pit and the junction of sidewall are done fillet and are processed, casting The opening part of pit does fillet and processes；Such structure can make stripping result more preferable.

Preferably, the end face of described front clinch is less than the bottom surface of rear clinch, rear clinch Top is shaped with cambered surface, and rear clinch is also shaped with guiding gutter；Because mould entirety is to need one piece Block is fixed on and works on chain, so the rear clinch of previous piece of mould to be overlapped on latter one piece On the front clinch of mould, gap is almost nil, the cambered surface on clinch top and being shaped with after mould Guiding gutter can make to water the molten steel on rear clinch, be diverted to the casting of front and back In pit, it is to avoid also protect mould while the wasting of resources, reduce maintenance cost.

Preferably, mould generally acid bronze alloy magnesium iron is made；This material is resistant to be up to The high temperature of 1650 degrees Celsius, prevents burning and melting when using under molten steel high temperature, in system During modeling tool, additionally it is possible to ensure the smooth of mold outer surface so that the material cast is not easy Adhesion, improves demoulding efficiency from basic material.

The present invention possesses advantages below: material is cheap and easy to get, can tolerate high temperature, tolerates molten steel Impact erosion, mould structure is simple, after treatment of details, it is possible to the perfect demoulding, demolding rate exceedes 99 percent, it is ensured that casting machine can be worked continuously.

Accompanying drawing illustrates:

Fig. 1 is the front view that mould accepted by continuous casting machine.

Fig. 2 is the top view that mould accepted by continuous casting machine.

Fig. 3 is the side view that mould accepted by continuous casting machine.

Fig. 4 is the enlarged drawing in Fig. 1 at B.

Fig. 5 is the enlarged drawing in Fig. 3 at C.

In figure: die main body 1, casting pit 2, front clinch 3, rear clinch 4, fixing ear 5, Fixed bolt hole 6, reinforcement 7, cambered surface 41 and guiding gutter 42.

Detailed description of the invention:

Refer to continuous casting machine as shown in Figures 1 to 5 and accept mould, including mould master Body 1 and the casting pit 2 being evenly distributed on die main body；Die main body is rectangle structure, The upper plane of the front and rear portions of die main body is shaped with front clinch 3 and rear clinch 4, mould master Fixing ear 5 is installed in the middle part of the dual-side of body, fixing ear 5 is shaped with fixed bolt hole 6, Gu The junction determining ear 5 and die main body 1 is shaped with oblique pull shape reinforcement 7.

Preferably, described casting pit 2 in truncated rectangular pyramids shape, the casting bottom surface of pit 2 and casting The opening of pit 2 is all square, the base a length of 15～25mm of casting pit 2, casting The top margin a length of 70～80mm of pit 2, the degree of depth of casting pit 2 is 32～36mm；Four ribs The casting pit of platform shape can allow releasing agent uniformly spray in its surface, and under this ratio Casting pit can meet client's requirement to product, can guarantee that again the more preferable demoulding, make to water Casting machine can work continuously, improves production efficiency.

Preferably, the described bottom surface of casting pit 2 and the junction of sidewall are done fillet and are processed, and water The opening part of foundry pit groove 2 does fillet and processes；Such structure can make stripping result more preferable.

Preferably, the end face of described front clinch 3, less than the bottom surface of rear clinch 4, overlaps afterwards The top in portion 4 is shaped with cambered surface 41, and rear clinch 4 is also shaped with guiding gutter 42；Because mould Entirety one piece of block of needs is fixed on chain and works, so the rear clinch of previous piece of mould Being overlapped on the front clinch of rear one piece of mould, gap is almost nil, clinch top after mould Cambered surface and the guiding gutter being shaped with of end can make to water the molten steel on rear clinch, before being diverted to In face and casting pit below, it is to avoid also protect mould while the wasting of resources, reduce Maintenance cost.

Embodiment: be arranged on the driving chain of continuous casting machine by fixing ear, die main body is then One piece of block is the most adjacent, and the lower plane of the rear clinch of first piece of die main body rides over second piece of mould In the upper plane of the front clinch of tool, by that analogy, form a long chain structure, molten steel Pour into from ladle in the casting pit of die main body, because molten steel is flowing continuously, certainly Can flow in the cambered surface of rear clinch, cambered surface and guiding gutter the casting pit before and after being diverted to In, prevent molten steel to run off.
