Abstract
The utility model discloses a submersed nozzle made of aluminum/zirconium/carbon, which is not required for preheating and baking and comprises a body (1) and a slag line (2), wherein a layer of carbon-free lining (3) is covered on the inner walls of the body (1) and the slag line (2) and can be made of any type of material as follows: zirconium, corundum, spinel and quartz. The whole inner hole of the submersed nozzle made of aluminum/zirconium/carbon is made of carbon-free materials which have lower heat transfer rate, so that the temperature transmitting time of the nozzle wall is prolonged, and the cracking of the nozzle caused by dramatic temperature change during the molten-steel casting process is avoided. Therefore, the submersed nozzle does not need to be baked before use.
Description
Technical field
The utility model relates to a kind of immersion nozzle for continuously casting.
Background technology
The zirconium carbonaceous material that aluminium zirconium carbonaceous submersed nozzle in use has stronger antiscour, erosion-resisting characteristics, particularly slag lining has improved life-span at the mouth of a river greatly, provides good condition to continuous casting steel machine.But owing to contain the extraordinary carbon of thermal conductivity in the material, can cause casting during molten steel mouth of a river Yin Wendu sharply change and form stress and produce cracking phenomena.Therefore the mouth of a river must be carried out the condition that strict baking just can reach use before use.If baking temperature is not in place, at the casting molten steel in a flash, the mouth of a river may crackle occur because of the thermal shock resistance difference, influences the quality of steel billet, even may cause product quality accident, brings very big economic loss to steel mill; If stoving time is long, the large-area volatilization of inoxidzable coating meeting on surface, the mouth of a river, do not have anti-oxidation effect, cause the graphite in the aluminium zirconium carbonaceous material oxidized, exposed corundum and zirconia are easy to be finished by molten steel scouring, reduce the life-span at the mouth of a river greatly, even reached the state that can't use.
Summary of the invention
Problem to be solved in the utility model provides a kind of aluminium zirconium carbonaceous submersed nozzle that does not need to carry out the preheating baking.
The utility model aluminium zirconium carbonaceous is exempted to toast submersed nozzle and is comprised body 1 and slag line 2, covers the carbon-free liner 3 of one deck on the inwall of body 1 and slag line 2.The material of carbon-free liner 3 can be wherein any of zirconium matter, corundum matter, spinelle, quartziferous.
Because it all is carbon-free material that the utility model aluminium zirconium carbonaceous exempts to toast the whole endoporus of submersed nozzle, the coefficient of overall heat transmission of material is lower, thereby prolonged the time that mouth of a river wall thickness temperature is transmitted, and then avoided temperature hurried variation in casting molten steel process and make the mouth of a river cracking occur.Therefore the utility model does not need to toast before use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model aluminium zirconium carbonaceous exempts to toast submersed nozzle;
Fig. 2 is the structural representation of baking-type submersed nozzle.
The specific embodiment
The utility model aluminium zirconium carbonaceous is exempted to toast submersed nozzle and is comprised body 1 and slag line 2, covers the carbon-free liner 3 of one deck on the inwall of body 1 and slag line 2.The material of carbon-free liner 3 can be wherein any of zirconium matter, corundum matter, spinelle, quartziferous.The material of body 1 is an aluminium carbon material, and the material of slag line 2 is a zirconium carbon material.
The production method that the utility model aluminium zirconium carbonaceous exempts to toast submersed nozzle is: add certain plastic material earlier in carbon-free inner lining material, inner lining material being put into the vacuum muller fully mixes again, make it have certain plasticity, make the material cake of suitable thickness, to expect that then cake is attached on the mould of product, assemble gum cover, populated in order other aluminium zirconium material with carbon element, mould sealing back compression moulding.
