Abstract

The invention relates to a torpedo ladle lining repair gunning mix, belonging to the technical field of torpedo ladles for transporting molten iron. The torpedo ladle lining repair gunning mix comprises the following components in percentage by weight: 45-60% of brown fused alumina particle, 10-20% of silicon carbide particle, 1-5% of kyanite powder, 1-5% of Gangxi earth, 1-10% of active alpha-Al2O3 powder, 1-7% of silicon micropowder, 1-5% of metallic silicon powder, 0-5% of ball pitch, 0-5% of amorphous graphite and 2-10% of pure calcium aluminate cement. The raw materials are weighed according to the particle sizes and proportions and uniformly mixed in a mixer. The torpedo ladle lining repair gunning mix has favorable refractoriness, oxidation resistance and slag iron permeation and corrosion resistance at the torpedo ladle service temperature of 1400-1530 DEG C.

Description

A kind of torpedo tank liner repairing Gunning refractory
Technical field
The invention belongs to transportation molten iron fish torpedo ladle technical field, especially relate to a kind of torpedo tank liner repairing Gunning refractory.To slow down its bricking erosive velocity, to improve the fish torpedo ladle repairing inner liner Gunning refractory in work-ing life.
Background technology
Fish torpedo ladle is one of main Thermal Equipment of Molten Iron Transportation between iron-smelting blast furnace and steel-making converter, has the advantages such as dress molten iron capacity is large, hot metal temperature drop is low, is used widely.The cycle of operation is longer, approximately 10～16 months.In long-term operational process, torpedo tank liner refractory materials is subject to washing away, being oxidized of slag, iron and permeates erosion etc., and part or big area occur damaged, affect its safe operation and work-ing life.The overhaul of torpedo tank liner refractory materials, build maintenance by laying bricks or stones, need to consume a large amount of human and material resources and time, production cost is higher.
Along with the requirement of the cost of resistance to material of continually strengthening and day by day strengthening of smelting iron and steel operation, improve fish torpedo ladle work-ing life, reducing fish torpedo ladle refractory consumption rate cost has become the problem of technician's tackling key problem.One of the approach that improves the life-span, adopts repairing inner liner maintenance technology exactly, except overhaul, in repair technology such as mending maintenance by replacing a damaged part, torpedo tank liner refractory materials spray repair maintenance technology is effective mode.Its construction is convenient, speed is fast, consuming time low, greatly improved the turnover operational efficiency of fish torpedo ladle, effectively repaired the bricking of badly broken region, improved fish torpedo ladle work-ing life.
Summary of the invention
The object of the present invention is to provide a kind of torpedo tank liner repairing Gunning refractory, can meet torpedo tank liner repairing needs, improve fish torpedo ladle and can reduce again the Gunning refractory of fish torpedo ladle refractory consumption rate cost work-ing life.
For achieving the above object, the present invention can take following technical proposals:
