Abstract
The utility model relates to the field of metallurgical iron-making equipment, in particular to a novel tapping spout of a forehearth (3), the technical scheme adopted by the utility model is as follows: the novel tapping spout of the forehearth (3) comprises a tapping spout body (1) and a guide groove (2), the tapping spout body (1) is connected with a tapping hole of the forehearth (3), a notch I (4) is arranged at the bottom part of the tapping spout body (1) and at the end which is far away from the tapping hole, the guide groove (2) is arranged at the lower part of the tapping spout body (1), the guide groove (2) is communicated with the notch I (4) of the tapping spout body (1), the back end of the guide groove (2) is hinged with the tapping spout body (1), a notch II (5) is arranged at the bottom part of the front end of the guide groove, and the notch II (5) corresponds to the position above a ladle (6). The novel tapping spout of the forehearth is characterized by simple structure, convenient operation, low cost, capability of controlling the flow volume and the flow rate of molten iron and the like.
Description
Technical field
The utility model relates to a kind of metallurgical iron-making devices field, specifically a kind of iron notch of novel forehearth.
Background technology
Forehearth is requisite a kind of device in the blast furnace ironmaking, and the one end is communicated with blast furnace, and the other end is provided with iron notch, and the notch of the iron notch of forehearth is corresponding to ladle, and molten iron flows to ladle by iron notch again by the blast furnace forehearth of flowing through.Traditional iron notch can not be controlled the flow and the flow velocity of molten iron, when the molten iron flow velocity is very fast, directly pours ladle, and impulsive force is big, and molten iron splashes and hurts sb.'s feelings easily, poor stability; In addition in some special process, flow to molten iron also has requirement, as do the spheroidising of spheroidal graphite cast-iron, before spheroidising, the nodulizer consumption is that the weight according to molten iron calculates, and is strict to the weight of molten iron of the injection in the ladle, if molten iron too much easily causes decaying spheroidisation, influence product quality, even cause and scrap.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple in structure that the utility model provides, and is convenient to operation, and cost is low, can control the novel forehearth iron notch of iron flow and flow velocity.
The technical solution adopted in the utility model is: a kind of novel forehearth iron notch, comprise iron notch body and guiding gutter, described iron notch body is communicated with the tapping hole of forehearth, in the bottom of iron notch body, be provided with notch I away from that end of tapping hole, bottom at the iron notch body is provided with guiding gutter, described guiding gutter communicates with the notch I of iron notch body, the rear end of this guiding gutter and iron notch body are articulated and connected, its front bottom end is provided with notch II, and described notch II is corresponding to the ladle top.
The utility model is owing to be provided with iron notch body and guiding gutter, guiding gutter is articulated and connected in the bottom of iron notch body, molten iron flows into the iron notch body earlier from forehearth, flow in the ladle through guiding gutter, the weight of molten iron of required injection has reached requirement in ladle, as long as stir guiding gutter again, make notch II remove the ladle top, molten iron will flow into other place, thereby guarantees that the molten iron in the ladle can be inexcessive, has guaranteed the quality of foundry goods; When the flow velocity of molten iron is too fast, stir the guiding gutter certain angle, make the sidewall of guiding gutter block the part of notch I, just can reduce the flow velocity of molten iron, easy to operate; The utility model is separately positioned on the bottom of iron notch body and guiding gutter with notch, is arranged on a side with original notch and compares, and the inertia when the available buffer molten iron is gone out notch has reduced the phenomenon that molten iron splashes and hurts sb.'s feelings, and is rational in infrastructure.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise iron notch body 1 and guiding gutter 2, described iron notch body 1 is communicated with the tapping hole of forehearth 3, in the bottom of iron notch body 1, be provided with notch I 4 away from that end of tapping hole, the size of notch I 4 is greater than the size of tapping hole usually.Be provided with guiding gutter 2 in the bottom of iron notch body 1, described guiding gutter 2 communicates with the notch I 4 of iron notch body 1, the rear end of this guiding gutter 2 and iron notch body 1 are articulated and connected, its front bottom end is provided with notch II 5, usually the size of notch II 5 is slightly larger than the size of notch I 4, and described notch II 5 is corresponding to ladle 6 tops.
During use, smelt good molten iron behind blast furnace inflow forehearth 3, flow into iron notch body 1 through tapping hole, flow into guiding gutter 2 through notch I 4 again, flow in the ladle 6 of its below from notch II 5 then, after the molten iron in the ladle 6 has reached the weight of regulation, stir guiding gutter 2 it is turned an angle, notch II 5 produces ladle 6 positions, and molten iron just no longer flows in the ladle 6, thereby guaranteed that the molten iron in the ladle 6 can be inexcessive, guaranteed the quality of foundry goods.
The utlity model has simple in structure, convenient operation, cost is low, can control the characteristics such as iron flow and flow velocity.
Claims (1)
1. a novel forehearth (3) iron notch, it is characterized in that: comprise iron notch body (1) and guiding gutter (2), described iron notch body (1) is communicated with the tapping hole of forehearth (3), bottom in iron notch body (1), that end away from tapping hole is provided with notch I (4), be provided with guiding gutter (2) in the bottom of iron notch body (1), described guiding gutter (2) communicates with the notch I (4) of iron notch body (1), rear end of this guiding gutter (2) and iron notch body (1) are articulated and connected, its front bottom end is provided with notch II (5), and described notch II (5) is corresponding to ladle (6) top.
