Three, utility model content
In order to solve the problems of the technologies described above, the purpose of the utility model just provides a kind of permeable refractory and becomes the core tool, in order to replace the existing moulding that adds or manually put the pore-forming core material of low ignition point in mould in forming process in shaping raw material, the penetrating rate of bringing in the traditional mode of production of pore is low to solve, the shape of pore and distribution can not get guaranteeing, have handling safety hidden danger, moulding productivity ratio and utilization rate of equipment and installations is low, can't satisfy problem such as special ventilative technological requirement.
In order to solve the problems of the technologies described above, the utility model is achieved in that the pore-forming core bar of being made by the low ignition point material, the horizontal muscle that connects, the perpendicular muscle that connects is combined into a basket cage construction with location even muscle, wherein pore-forming core bar is all put horizontal and is connected on the muscle, the perpendicular muscle that connects is all put horizontal even between muscle, on the position of the every perpendicular even muscle in basket cage construction bottom, be provided with the location rib, during use, before the raw material of permeable refractory goods adds mould, permeable refractory product molding core tool of the present utility model is put into mould, again the feeding quantity of deployed loose refractory raw material by the moulding process stipulation added in the mould, the demoulding after moulding, produce the permeable refractory goods briquet that inside is carried pore-forming core tool secretly, after high-temperature firing or dry the processing, obtain permeable refractory goods certified products.
Described low ignition point material, its burning-point should be lower than 250 ℃, can be various plastics, also can be any or combinations more than two kinds in cardboard, rubber or the tarred brown paper;
Described core bar is a main pore-forming spare of the present utility model, and its shape, Size Distribution are decided according to the technological requirement of using the permeable refractory goods.
Described horizontal muscle and the perpendicular muscle that connects of connecting is to guarantee core bar distributing position.
Described positioning bar, its effect are to guarantee that the position of permeable refractory product molding core tool in mould meets the gas cell distribution requirement.
Described basket cage construction should once form in permeable refractory product molding core tool manufacturing process.
A kind of permeable refractory product molding of the utility model core tool has the following advantages:
1,,, need not increase the operation of loosing core firing or just can burning cinder during dry the processing because permeable refractory product molding core tool has the low ignition point characteristic.
2, owing to adopt the basket cage construction, in reinforced forward direction mould, once play core, just can reach the pore-forming requirement, both improved moulding productivity ratio, also avoided owing to repeatedly put the potential safety hazard that the core bar brings.
3, the basket cage construction of permeable refractory product molding core tool, the fixed in shape, position that can guarantee permeable refractory goods inner air vent accurately, be evenly distributed, be content with very little and use the technological requirement of permeable refractory goods.
4, when the technology of using the permeable refractory goods during, can satisfy by geomery, a basket basket structure of accomplishing hole core bar easily various different requirement of proposition such as the porosity, gas cell distribution and the penetrating mode of pore.
5, can increase substantially the shaping speed of permeable refractory goods, boost productivity and utilization rate of equipment and installations.
6, simple in structure, economical and practical, easy to implement.
