Abstract
The utility model provides a distributor chute lining plate of an iron making blast furnace, which belongs to the technical field of blast furnace iron making; the distributor chute lining plate is shaped like a U-shaped groove; the distributor chute lining plate is characterized in that through holes are uniformly formed in the U-shaped groove lining plate in a thickness direction; alloy through nails are placed in the through holes to run through the U-shaped groove lining plate; and nail head directions of the through nails are toward the external side surface of the U-shaped groove. A problem that influences on production and losses of chute spare parts are directly caused by reduction of service life because durable alloy blocks generally fall off due to furnace temperature fluctuation and casting quality defects in the production process of the distributor chute lining plate of the iron making blast furnace is solved.
Description
Technical field
The utility model belongs to the technical field of smelting of blast furnace iron, relates to a kind of improvement of iron-smelting blast furnace distribution chute liner plate.
Background technology:
The employed distribution chute liner plate of each blast furnace of iron work all is to be made with the founding of alloy block high temperature.In process of production, often run into furnace temperature fluctuation and casting quality defective and the wear-resisting alloy block that causes comes off, thus reduction of service life; The distribution chute mean lifetime of this structure of using at present will be changed once about 1 year, change chute at every turn and need stop phoenix 6-8 hour, directly cause influence to produce and cause the loss of chute spare part; As production unit, stop production and change chute, bigger to production loss; Stopping production 6-8 hour, relatively and the working hour 1/3rd to 1/4th.
Summary of the invention:
The goal of the invention of the utility model provides a kind of iron-smelting blast furnace distribution chute liner plate of long service life.
The purpose of the utility model is realized by following mode:
Iron-smelting blast furnace distribution chute liner plate, the shape of liner plate are U type groove shapes, it is characterized in that: the thickness direction on U type slot liner plate evenly is covered with through hole, and the alloy drift bolt places through hole to connect U type slot liner plate, and the ailhead direction of drift bolt is to the outer side of U type groove.
Beneficial effect: owing on the chute liner plate, be uniformly distributed with the drift bolt of alloy, and drift bolt is to connect on the end face of U type slot liner plate, reached one be ground to the end effect, promptly prolonged the bulk life time of chute, reduce blast furnace because of changing the production loss that chute stops production and causes.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
Embodiment:
Iron-smelting blast furnace distribution chute liner plate, the shape of liner plate 2 are U type groove shapes, it is characterized in that: the thickness direction on U type slot liner plate 2 evenly is covered with through hole, and alloy drift bolt 1 places through hole to connect U type slot liner plate, and the ailhead direction of drift bolt is to the outer side of U type groove.
Because the utility model has been uniformly distributed with alloy drift bolt 1 on chute liner plate 2; And drift bolt 1 is what to be connected at the thickness direction of U type slot liner plate 2, reached one be ground to the end effect because the alloy wear-resisting degree is high; In production run; Can not take place promptly to have prolonged the work-ing life of chute liner plate, reduce the loss of producing again because blast furnace temperature changes the phenomenon that causes alloy to come off.
Contrast with NeiMenggu BaoGang GangLian Co., Ltd's iron work blast furnace condition of production: 2200 cubic metres blast furnace; Its chute liner plate is 7, the annual replacing once, and only the liner plate expense is with regard to more than 20 ten thousand; Whole chute liner plate adds the manufacturing cost about 500,000 of body; After the transformation, the 2-3 that can increase the service life doubly can reduce expenses more than 1,000,000 yuan.
Claims (1)
