Abstract

The invention discloses a submerged nozzle brick which comprises a spinel layer in the inner layer, wherein the spinel layer is coated with an alumina-carbon layer, and a zirconia-carbon layer is arranged at a place close to the end part of the alumina-carbon layer. Compared with the prior art, the submerged nozzle brick has the characteristics of high fireproofness, high high-temperature strength, low linear change rate, volume stability, good corrosion resistance, etc.;, the zirconia-carbon layer is adopted for reinforcement at a submerged part, so that a good heat insulation effect can be exerted; when aging damage occurs, the submerged nozzle brick can be used simply by replacing the corresponding zirconia-carbon layer.

Description

A kind of submersed nozzle brick
Technical field
The invention belongs to fire resisting material field, be specifically related to a kind of submersed nozzle brick.
Background technology
Steel mill needs molten steel is guided out converter after steel-making completes, traditional steel-making fire door uses refractory brick to be laid to the lower mouth of a river, lower nozzle brick needs directly to contact with molten steel, it is thus desirable to the refractory brick that selection heat-resistance coefficient is high, therefore cost is the highest, and need to change after using certain number of times, the most to a certain degree improve production cost.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of extended nozzle.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically performed by: a kind of submersed nozzle brick, including the spinel layer of internal layer, spinel layer is coated with aluminum carbon-coating, and described aluminum carbon-coating is provided with zirconium carbon-coating near end.
Wherein, described aluminum carbon-coating be shaped as horn-like.
Wherein, described zirconium carbon-coating does not contacts with spinel layer.
Beneficial effect: the present invention is compared with conventional art, there is the features such as refractoriness is high, elevated temperature strength is high, Linear change rate is low, volume stability, corrosion-resistant property are good, use zirconium carbon-coating to reinforce at immersion to can be good at playing thermal resistance effect, only need to change corresponding zirconium carbon-coating when old damage occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
A kind of submersed nozzle brick as shown in Figure 1, including the spinel layer 1 of internal layer, spinel layer 1 is coated with aluminum carbon-coating 2, and described aluminum carbon-coating 2 is provided with zirconium carbon-coating 3 near end, being shaped as of described aluminum carbon-coating 2 is horn-like, and described zirconium carbon-coating 3 does not contacts with spinel layer 1.
