Abstract
The invention provides an additive adding device for liquid steel pouring. The additive adding device for liquid steel pouring comprises a conveying pipeline; a charging hopper with a valve is welded to a side surface opening close to one end of the conveying pipeline; a fine steel pipe is inserted into one end, close to the charging hopper, of the conveying pipeline; the fine steel pipe and the conveying pipeline are welded and sealed; the fine steel pipe extends into the center of the side surface opening of the conveying pipeline; air is blown into the conveying pipeline through the fine steel pipe; argon gas is adopted as conveying gas and fed into the conveying pipeline to form negative pressure; an additive or alloy powder is sucked and enters liquid steel along with the gas; by adjusting the opening degree of the valve and the flow and pressure of the argon gas fed into the fine steel pipe, the quantity of the additive is adjusted, and the additive is uniformly added into the liquid steel. The additive adding device for liquid steel pouring is simple in structure, safe and reliable during usage, capable of adjusting adding quantity in real time and high in practicability.
Description
Technical field
The invention belongs to steel casting field, relate to ferrous metal in pouring molten steel process, non-ferrous metal inner additive adds technology, particularly a kind of pouring molten steel additive adding apparatus.
Background technology
In casting industry, its product just will can obtain qualified chemical composition, interior tissue and mechanical performance through working procedures, to meet different instructions for uses, for this reason, different additive or alloy to be added equably in molten steel according to different requirements in smelting and pouring process.
Leak steel ladle the end of for, molten steel is in bottom water outlet, and the useful space is smaller, adds additive and acquires a certain degree of difficulty, and has not both ensured the uniformity added, more dangerous again, is badly in need of a kind of novel interpolation instrument, to meet Production requirement.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of pouring molten steel additive adding apparatus, additive adds even, safe and reliable and addition is adjustable.
The present invention adopts following scheme to achieve these goals:
A kind of pouring molten steel additive adding apparatus, comprise conveyance conduit, near the lateral opening of conveyance conduit one end the charging hopper of welded bands valve, in charging hopper one end, fine steel tube is inserted at conveyance conduit, fine steel tube and conveyance conduit welded seal, fine steel tube extend into the center of conveyance conduit lateral opening.
Further, at the charging hopper from conveyance conduit pipe end 50mm place lateral location opening welded bands valve.
Further, the valve of described charging hopper adopts ball valve.
Further, described conveyance conduit adopts φ 32 × 2.5 stainless steel tube to make.
Further, described fine steel tube adopts the stainless steel tube of φ 12 × 1 to make.
The present invention includes conveyance conduit, lateral opening in conveyance conduit one end the charging hopper of welded bands valve, fine steel tube is inserted in conveyance conduit one end, blown in conveyance conduit by fine steel tube, adopt argon gas as conveying gas, pass in conveyance conduit and form negative pressure, additive or alloy powder are sucked, enter in molten steel with gas, by adjusting the flow and the pressure that pass into argon gas in the aperture of valve and fine steel tube, thus regulate the amount of additive, additive is joined in molten steel uniformly, apparatus structure is simple, safe and reliable, and addition can be regulated in real time, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-conveyance conduit, 2-charging hopper, 3-ball valve, 4-fine steel tube.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below technical scheme in the present invention be clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the inventive system comprises conveyance conduit 1, near the lateral opening of conveyance conduit 1 one end the charging hopper 2 of welded bands valve, in charging hopper 2 one end, fine steel tube 4 is inserted at conveyance conduit 1, fine steel tube 4 and conveyance conduit 1 welded seal, fine steel tube 4 extend into the center of conveyance conduit 1 lateral opening.
Further, adopt the stainless steel tube of φ 32 × 2.5 to make conveyance conduit 1, be welded the funnel of a band valve from pipe end 50mm place lateral location opening; Adopt φ 12 × 1 stainless steel tube to make fine steel tube 4, fine steel tube 4 inserts conveyance conduit 1 and has welded sealing near one end of charging hopper 2 and stainless steel tube, and extend into the center of conveyance conduit 1 lateral opening.
Further, the valve of charging hopper 2 adopts ball valve 3.
During use, charging hopper 2 lower ball valve 3 is shut, additive is loaded in funnel, outlet, facing to the molten steel flow in cup, passes into argon gas in fine steel tube, is adjusted to suitable flow and pressure, slowly open valve, additive enters in molten steel with gas, serves crystal grain thinning, the effect of improving SNR.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
