Abstract
The utility model discloses a novel non-steel adhesion converter sublance, which comprises a converter sublance adapter and a probe assembly, wherein the probe assembly is mutually connected with the bottom part of the converter sublance adapter; the outer side of the converter sublance adapter or the probe assembly is provided with a composite coating. The chilling resistance and the rapid heating resistance are good, the bonding strength is high, the wettability between the sublance and molten steel is low, the steel slag adhesion prevention effect is obvious, the replacement frequency of the converter sublance adapter and the replacement frequency of a converter sublance sprayer are reduced, the production efficiency of a converter is improved, and the potential safety hazards of equipment and personnel are reduced, therefore, the novel non-steel adhesion converter sublance disclosed by the utility model is very high in economic benefit and use value.
Description
Technical field
The utility model relates to the smelting specific equipment, refers in particular to a kind of novel non-stick steel revolving furnace sublance of smelting usefulness.
Background technology
In smelting process, need to measure the parameter in the stove, usually adopt sublance to carry out, sublance mainly carries out following measurement in convertor steelmaking process: 1) measure the molten steel degree of depth in the molten bath; 2) measure the carbon content of molten steel in the molten bath in the blowing; 3) blow end point is measured oxygen level and the carbon content of molten steel in the molten bath; 4) measure molten metal pool level.Therefore sampling, the measurement of sublance for the temperature variation in the research converting process, taken off C, removes P, gone the S rule that process data is provided, by these these data, in time optimize slag making and the oxygen supply system of converter, summed up in the short period of time the blowing technology of top and bottom combined blown converter, and the use of sublance, improved the equipment of converter, make stable operation, splash reduces, and the hit at first time level significantly improves, reduced and blown blow loss and the consumption that causes later, on average saved iron and steel stock and consume 5kg/t; Alleviate worker's labour intensity, improved Working environment.Sublance comprises sublance body, and at present, the sublance of domestic usefulness is dependence on import basically, and price is very expensive.
Yet because slag is not changed goodization thoroughly in the converting process, poor fluidity, the metal splash is serious, and perhaps the rifle position is excessively low etc., and factor causes revolving furnace sublance to be easy to steel bonding.When the revolving furnace sublance steel bonding is few, can rinse with slag in the blowing later stage.But when the revolving furnace sublance steel bonding is serious, need to processes the laggard pedestrian worker of blow off, otherwise must change revolving furnace sublance.Therefore can learn by above-mentioned treating method, be that the consumption, tap to tap time etc. of quality, lining life, material to steel all can have detrimentally affect.
The utility model content
The utility model purpose provides a kind of non-stick steel revolving furnace sublance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel non-stick steel revolving furnace sublance, it comprises: revolving furnace sublance is taken over and is taken over the probe assembly that the bottom is connected with revolving furnace sublance, and wherein the outside of revolving furnace sublance adapter or probe assembly has a compound coating.
On the basis of technique scheme, further comprise following attached technical scheme:
Described compound coating comprises the antistick layer that is positioned at inboard bonding coat, high-temperature-resistant layer and is positioned at the outside at least.
Described revolving furnace sublance is taken over nitrogen tube and the cable splice that comprises water inlet pipe, rising pipe, is positioned at the water inlet pipe top, and wherein revolving furnace sublance is taken over the tracheae that comprises the container cavity that links to each other with inlet tube and outlet tube, be connected with nitrogen tube and extend in the container cavity, is arranged on the pipe connecting in the container cavity and is positioned at the bottom and allows probe assembly to extend into the end of container cavity.
Described probe assembly comprises that probe holder, probe connector and the connector of will popping one's head in are fixed to the nut of probe holder, the holder of wherein popping one's head in has the fixed head that can extend in the pipe connecting and the airway that docks with tracheae, and fixed head seals with pipe connecting, end respectively.
Because the utilization of technique scheme the utlity model has following advantages:
Have good heat impact strength and high bonding strength, poor with the wettability of molten steel, the effect of obvious anti-stick slag is arranged, reduce the replacement frequency of revolving furnace sublance adapter and revolving furnace sublance shower nozzle, improve converter production efficiency, the potential safety hazard of minimizing equipment and the person has very large economic benefit and use value.
