Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
As shown in Figure 1, this device comprises casting ladle main body 8, casting ladle main body 8 bottom is provided with molten steel outlet 4, running channel 5 is provided with immediately below molten steel outlet 4, casting ladle main body 8 lateral wall is fixedly connected with suspending agent injection device, suspending agent injection device comprises storage portion and sprays the gas transmission portion of argon gas, storage portion comprises support 6, built with the suspending agent funnel 1 of suspending agent, funnel switch 2 and vertical tube connector 7, suspending agent 9 is placed in suspending agent funnel 1, the side of suspending agent funnel 1 is welded on casting ladle main body 8 lateral wall by support 6, vertical tube connector 7 is connected with bottom suspending agent funnel 1, vertical tube connector 7 is communicated with gas transmission portion, vertical tube connector 7 is provided with funnel switch 2, control the input of suspending agent 9, gas transmission portion comprises appendix 10, gas transmission switch 11 and playpipe 3, and appendix 10 root opening is provided with gas transmission switch 11, and appendix 10 is connected with playpipe 3, and playpipe 3 is connected with the bottom angled of the vertical tube connector 7 in storage portion, in 120 ° of angles.The exit of playpipe 3 is positioned at molten steel and exports 4 side-lower 100-200mm places, in time the suspending agent 9 of parcel argon gas is fully mixed with the molten steel fallen, just in time by the impulsive force of argon gas, suspending agent 9 is squeezed in molten steel 12, and mix, be convenient to suspending agent 9 and argon gas efficiently passes through smoothly, do not remain in a standstill, and fully contact.
Its concrete using method is:
Open casting ladle main body 8 bag bar, molten steel 12 flows out from the molten steel outlet 4 bottom casting ladle main body 8 by gravity, after general 2 seconds (steel flow stabilizes), open gas transmission switch 11, open funnel switch 2 afterwards, suspending agent 9 enters playpipe 3 by deadweight whereabouts, and rely on the impulsive force of argon gas, squeeze in molten steel 12 stream, and mix, enter running channel 5 with molten steel 12 afterwards.Simultaneously owing to having argon shield around suspending agent 9, the oxygen of suspending agent 9 in air also can be prevented to be combined, form the quality that oxidizing slag affects molten steel 12.
By said apparatus, molten steel 12 and suspending agent 9 just mix above running channel 5, enter in running channel 5, also there will not be attached wall condensation phenomenon, therefore can flow in casting mold swimmingly and go.Solve the drawback of conventional suspension cup device, Suspending Cast method is applied completely, there is higher application value.
