Description
Technical field
The utility model relates to a kind of casting and metallurgy industry is produced stainless rare earth adding instrument, produces specifically to contain the dispenser of yttrium stainless steel with interpolation calcium metal and yttrium master alloy.
Background technology
In casting and metallurgy industry, produce in the stainless process, for reducing inclusion and the quantity in the molten steel, the general interpolation calcium metal that adopts carries out the calcium processing, its method is to adopt throw-in play and injection feeding technology, and inclusion is carried out denaturing treatment, changes the type and the form of inclusion.Traditional throw-in play is calcium metal to be connect to drop in the ladle handle, and can not effectively protect because of it, is now replaced by injection feeding technology gradually.Injection feeding technology is to adopt the directly wire rod of feeding 1-1.6 kilogram/ton in ladle, the technology comparative maturity, but injection feeding technology is limited to the inclusion modification processing power, can not remove dystectic oxide compound.Adding method for rare earth mainly is to pour modes such as method, throw-in play, hello silk method.1, pouring method is to add rare earth at ladle bottom earlier, protective cover in the above again, carry out rare earth after molten steel pours in the ladle and handle, adopt this method technological operation simple, but its weak point is: the rare earth of adding and the ratio of molten steel can not accurately be controlled, reaction is violent when just adding molten steel simultaneously, the tapping late phase reaction is slow, and molten steel middle-weight rare earths recovery rate is not high, for this reason, in order to guarantee finished product middle-weight rare earths total amount, add rare earth and occur adding excessive situation easily aborning; 2, throw-in play is that rare earth is added in the ladle with molten steel with metal shell sealing back, this method can more accurately be controlled adding quantity, but its weak point is: can not form effective protection in adition process, rare earth exists content of rare earth inhomogeneous easily at the surface oxidation of molten steel in the molten steel; 3, feed the silk method and only only limit to now add in the crystallization phase, along with MOLTEN STEEL FLOW is accurately adjusted add-on, adding precondition is that molten steel must add in the protective atmosphere condition, can not add with this method for the yttrium master alloy that can not be prepared into wire rod.In actual production process, before the interpolation calcium metal carries out the calcium processing and adds the rare earth of yttrium master alloy, must carry out pre-deoxidation to molten steel, the equipment that does not also have calcium metal and yttrium master alloy rare earth to add simultaneously at present.
Summary of the invention
It is a kind of in producing stainless process that the purpose of this utility model is to provide, can add calcium metal and yttrium master alloy simultaneously, to improve the recovery rate of calcium treatment effect and yttrium, reduce The amount of inclusions, and production simple to operate, easy to use contains the dispenser of yttrium stainless steel with interpolation calcium metal and yttrium master alloy.
For reaching above purpose, the technical scheme that the utility model adopted is: this production contains the dispenser of yttrium stainless steel with interpolation calcium metal and yttrium master alloy, by operating stick, permanent sleeve constitutes, the lower end of operating stick is fixed with permanent sleeve, operating stick and permanent sleeve are all made by refractory materials, the outer wall that it is characterized in that permanent sleeve is provided with the reaction contact hole, in the chamber of permanent sleeve, be provided with reaction material and throw in post, tumbler pin passes the through hole insertion reaction material of permanent sleeve upper end and throws in the hanging ring of post upper end, be fixed in the chamber of permanent sleeve so that reaction material is thrown in post, prevent its landing.The utility model is also implemented by following measure: described reaction material is thrown in post, by body skin, hanging ring, inner housing, the yttrium master alloy is filled the chamber, calcium metal is filled the chamber, plastics envelope film and refractory mortar plug constitute, body skin and inner housing are all the iron cylinder of lower ending opening, with the convenient reaction material of filling, inner housing is located at the endoceliac center of shell, the fixing hanging ring of going up on the upper surface of body skin, so that inserting, fixes by tumbler pin, the inner chamber of inner housing is filled the chamber for the yttrium master alloy, cavity between body skin inwall and the inner housing outer wall is that calcium metal is filled the chamber, the lower end that calcium metal in body skin is filled the chamber is provided with plastics envelope film, to prevent that the stopping composition that calcium metal is filled in the chamber from making moist, oral area is provided with the refractory mortar plug in the lower end of body skin, scatters out with the reaction material that prevents to fill.When using the utility model, reaction material is thrown in post handstand comes, lower ending opening upwards, in filling the chamber, the yttrium master alloy adds the yttrium master alloy earlier, in filling the chamber, calcium metal adds calcium metal again, and firmly with plastics envelope membrane cover, use the shutoff of refractory mortar plug at last on the lower port of body skin, reaction material is thrown in post be installed in the permanent sleeve, and get final product with tumbler pin is fixing, in the time of in joining ladle, with operating stick permanent sleeve is pressed in the bottom of ladle, molten steel passes reacting hole, earlier body skin is slowly melted, react with calcium metal, carry out calcium and handle, again inner housing is slowly melted, react with the yttrium master alloy, the yttrium master alloy is joined in the molten steel, and whole like this calcium is handled and the rare earth adding has just been finished.
The beneficial effects of the utility model are: handle with the calcium in the present producing stainless steel process and compare with rare earth adding method, can control the adding of calcium metal and yttrium master alloy rare earth simultaneously, prevent from stainless steel, to increase silicone content, improved the recovery rate of calcium treatment effect and yttrium, reduce The amount of inclusions, and can in time adjust yttrium master alloy additional proportion as required, simultaneously simple to operate, easy to use, reduce staff's labour intensity, improved working efficiency.
