Abstract
The utility model discloses a skimming tool for blast -furnace casting, including body, crossbeam, body upper portion was equipped with the iron runner, it is equipped with to cross the iron runner top the crossbeam, be equipped with the perforation on the crossbeam, on the body, cross the iron runner both sides and be equipped with molten iron entry, molten iron export respectively, be equipped with " V " shape groove in the molten iron export, on the arbitrary lateral wall of body, be equipped with first skimmer gate between crossbeam and the molten iron entry, on another lateral wall of body, be equipped with the second skimmer gate between the export of crossbeam and molten iron. The utility model discloses a minimum that sets up through -hole and through -hole on the crossbeam is higher than molten iron entry minimum, and messenger's ladder pole when changing the crossbeam can directly penetrate the through -hole, and it is laborsaving to save trouble, set up the skimmer gate on the body lateral wall behind the crossbeam, the molten iron export is gone up and is set up " V " shape groove, makes the skimming tool clear away scum more thoroughly.
Description
[technical field]
The utility model relates to the technical field of Metal smelting, particularly a kind of technical field of blast furnace casting skimmer.
[background technology]
Along with the quick growth of China's iron and steel output, the focus that the raising of the various quality of materials in stokehold has become refractories industry to pay close attention to.Skimmer is the main device of blast furnace steel-making stokehold slag iron treatment system, and the length of skimmer replacing construction directly has influence on the normal production order of blast furnace, then has influence on the economic benefit of steel mill.Existing skimmer is all adopt the on-the-spot bulk cargo ramming of punching block to form, and present skimmer body and crossbeam are integrally, when using and whole skimmer will being scrapped after repairing one end time, again makes skimmer.Find in practical application that crossbeam is directly subject to washing away of slag iron, be easy to be etched and be oxidized, the body of bottom is then not easily etched and is oxidized, but once lintel damages, whole skimmer all will be scrapped replacing, has not only wasted resource but also lost labor.
Nowadays occur that a kind of crossbeam and body can separate and the removable skimmer of crossbeam, but design in the structure of crossbeam and be not convenient for replacing, and body only before crossbeam has skimming hole, then can be gone out without mouth by the scum of crossbeam for unexpected in molten iron.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of blast furnace casting skimmer, and the replacing of crossbeam can be made more convenient, and the removing for scum is more thorough.
For achieving the above object, the utility model proposes a kind of blast furnace casting skimmer, comprise body, crossbeam, described body upper part was provided with iron runner, described mistake above iron runner is provided with described crossbeam, described crossbeam is provided with perforation, on described body, excessively, iron runner both sides are respectively equipped with molten iron entrance, molten iron exports, described molten iron outlet is provided with " V " shape groove, on any sidewall of described body, be provided with the first skimming hole between crossbeam and molten iron entrance, on another sidewall of described body, crossbeam and molten iron be provided with the second skimming hole between exporting.
As preferably, described crossbeam can propose above body, and described perforation lower-most point is higher than molten iron entrance lower-most point.
As preferably, described crossbeam perigee distance crosses 5cm bottom iron runner.
As preferably, described to cross iron runner cross section be inverted trapezoidal.
As preferably, described molten iron outlet is lower than molten iron entrance.
As preferably, described crossbeam is the ducted body of the thick 6cm of shell.
The beneficial effects of the utility model: the utility model by crossbeam, through hole is set and the lower-most point of through hole higher than molten iron entrance lower-most point, make change crossbeam time ladder bar directly can penetrate through hole, save trouble and labor; Body sidewall after crossbeam arranges skimming hole, and molten iron outlet is upper arranges " V " shape groove, makes skimmer remove scum more thorough.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the shaft side figure of a kind of blast furnace casting skimmer of the utility model;
Fig. 2 is the main skeleton view of a kind of blast furnace casting of the utility model skimmer.
In figure: the outlet of 1-body, 11-molten iron entrance, 12-molten iron, 121-" V " shape groove, 13-first skimming hole, 14-second skimming hole, 15-cross iron runner, 2-crossbeam, 21-perforation.
[embodiment]
Consult Fig. 1 and Fig. 2, a kind of blast furnace casting skimmer of the utility model, comprise body 1, crossbeam 2, described body 1 top was provided with iron runner 15, described mistake above iron runner 15 is provided with described crossbeam 2, described crossbeam 2 is provided with perforation 21, on described body 1, cross iron runner 15 both sides and be respectively equipped with molten iron entrance 11, molten iron outlet 12, described molten iron outlet 12 is provided with " V " shape groove 121, on any sidewall of described body 1, the first skimming hole 13 is provided with between crossbeam 2 and molten iron entrance 11, on described another sidewall of body 1, crossbeam 2 and molten iron are provided with the second skimming hole 14 between exporting 12.Described crossbeam 2 can propose above body 1, and described perforation 21 lower-most point is higher than molten iron entrance 11 lower-most point.Described crossbeam 2 perigee distance crosses 5cm bottom iron runner 15.Described iron runner 15 cross section is excessively inverted trapezoidal.Described molten iron outlet 12 is lower than molten iron entrance 11.Described crossbeam 2 is the ducted body of the thick 6cm of shell.
A kind of blast furnace casting skimmer of the utility model, by crossbeam, through hole is set and the lower-most point of through hole higher than molten iron entrance lower-most point, make the ladder bar when changing crossbeam directly can penetrate through hole, save trouble and labor; Body sidewall after crossbeam arranges skimming hole, and molten iron outlet is upper arranges " V " shape groove, makes skimmer remove scum more thorough.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
