The document that document number is CN201257513Y and CN102039404A has been announced the combined type ventilating filling pipe end that a kind of moulding process is relative simply, production cost is relatively cheap, it is comprised of inside and outside two parts, inner is the ventilative core body of mechanical pressing, and outside is vibrating casting moulding pouring piece.The advantage of this kind of technique maximum is to have realized Non-carbonized, but also has some obvious shortcomings: at first, ventilative core body still adopts mechanical pressing, needs expensive hydraulic test; Secondly, outer seal adopts the vibrating casting moulding, very easily causes the vibration damage of ventilative core body, and yield rate is low, especially can stay the gas leakage hidden danger in the military service process, thereby affects the normal operation of continuous casting.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the carbon-free ventilating filling pipe end of the special steels such as a kind of moulding process is simple, low production cost, yield rate is high, reliability is high, applicable casting ultra-low-carbon steel is provided.
In order to realize above-mentioned purpose, the utility model is achieved through the following technical solutions:
A kind of carbon-free ventilating filling pipe end comprises: the means for ventilation of inside, the mouth of a river, the seal of outside/bottom, the mouth of a river, box hat, Argon pipe, the air chamber between means for ventilation and seal.
In above-mentioned carbon-free ventilating filling pipe end, the rim of a bowl above described means for ventilation part and following hollow cylinder are partly an integral body, are that vibration formation method is integrated poured forms in employing, material therefor is carbon containing not, for magnesia or magnesia spinel matter, after high temperature burns till, apparent porosity is controlled, good air permeability.
In above-mentioned carbon-free ventilating filling pipe end, described seal is coated on the means for ventilation outside and bottom, jointly forms an integral body, material therefor is carbon containing not, is spinel, mullite or corundum mullite rock, and molding mode is the gravity flow pouring moulding, the porosity is lower, and air-tightness is good.
In above-mentioned carbon-free ventilating filling pipe end, described air chamber is cylindric distribution along mouth of a river axial line.The formation method of air chamber is: at first, smear montan wax or the ceresine that one deck 1-2mm is thick in the means for ventilation outside; Then means for ventilation is fixed in mould, the gravity flow pouring formation of sealing component, make means for ventilation and seal form an integral body; Finally by this integral body in 300-350 ℃ of heat treatment, just form cylindric air chamber after the burning totally of montan wax or ceresine.
In above-mentioned carbon-free ventilating filling pipe end, described box hat is positioned at mouth of a river bottom, plays fit sealing part, fixedly Argon pipe and sealing function, and material is Q235A or Q235B.
In above-mentioned carbon-free ventilating filling pipe end, described Argon pipe is fixed on box hat, and communicates with cylindric air chamber bottom through seal, and material is 410S or 304 stainless steels.
Technique scheme of the present utility model compared with prior art has the following advantages: the neither carbon containing of (1) means for ventilation and seal is beneficial to the special steels such as casting ultra-low-carbon steel; (2) means for ventilation adopts the moulding of vibrating casting method, and technique is simple, with low cost; (3) seal adopts the moulding of gravity flow pouring method, and production efficiency and yield rate are high, the most important thing is: the gravity flow pouring moulding can not cause any damage to means for ventilation, and product quality significantly improves, and can ensure the trouble-free operation of continuous casting process.
