Abstract
The invention discloses an electric furnace smelting and inoculation treatment device. The device comprises a funnel support. A ladder is arranged on the outer side of the funnel support. A funnel is arranged at the upper end of the funnel support. A steel pipe inclining downwards is mounted at the discharge end of the funnel through a bearing. A steel pipe pull rod is fixedly connected with the steel pipe. The upper end of the steel pipe pull rod is fixedly connected with a transverse rotary handle. The other end of the rotary handle is rotatably arranged on the funnel support. An inoculant is added into the funnel. The steel pipe is connected with the funnel through a bearing so that the steel pipe can rotate by 180 degrees, and the inoculant flowing out of the steel pipe flows into an electric furnace nozzle. A pour-over method for inoculation is abandoned, the inoculation device capable of conducting flow inoculation on the electric furnace nozzle is adopted, the inoculant can evenly leak on molten iron, and the optimal inoculation treatment effect is achieved.
Description
Technical field
The present invention relates to melting and breed field, particularly belong to a kind of electro-smelting inoculation device.
Background technology
Along with the development of economic society, the domestic requirement to environmental protection is more and more higher.The environmental protection pressure faced as the foundry industry of industrial foundation wants big many, therefore forces Foundry Works to strengthen the input to environmental protection facility.In this context, eliminating furnace cupola, the electro-smelting changing more environment-protecting clean has become as a kind of trend of the times.But owing to electric furnace lacks the metallurgical reaction of furnace cupola, the molten iron degree of supercooling of institute's melting is big, if Metamorphism treatment is improper, then the mechanical performance of the foundry goods of cast might as well furnace cupola.How to strengthen inoculation, improve molten steel quality and become a problem.Owing to electric furnace converter nose is short, it has not been convenient to carry out inoculation on converter nose, most of Foundry Works all use embedment inovulant in casting ladle, and molten iron carries out inoculation directly into casting ladle.The pregnant effect of this inoculation treating method is the most not fully up to expectations, the advantage the most well having given play to electro-smelting, and the material level of foundry goods is the highest.If inovulant uniformly can be sprinkling upon on ferrum liquid stream when electric furnace taps a blast furnace, then pregnant effect can reach optimal.
Summary of the invention
It is an object of the invention to provide a kind of electro-smelting inoculation device, abandon the method for pouring and breed, use a kind of inoculation device carrying out current-following inoculation on electric furnace converter nose.
Technical scheme is as follows:
A kind of electro-smelting inoculation device, include funnel stand, staircase it is provided with outside funnel stand, funnel stand upper end is provided with funnel, the discharging end of funnel is provided with steel pipe diagonally downward by bearing, steel pipe pull bar it is fixedly connected with on steel pipe, steel pipe pull bar upper end is fixedly connected with horizontal turning handle, the turning handle other end rotates and is arranged on funnel stand, inovulant is added in funnel, steel pipe is connected by bearing with funnel, make steel pipe can with 180 degree of rotations, steel pipe flow out inovulant enter electric furnace converter nose.
Described bearing is arranged over flashboard, the laterally movable discharging end being arranged at funnel of flashboard.
Funnel is suspended in mid air by the funnel stand of the present invention, increases the gravity speed that inovulant flows out, and people climbs up platform from staircase, is added by inovulant in funnel, and steel pipe is connected by bearing with funnel, makes steel pipe can not hinder normal production with 180 degree of rotations.When electric furnace taps a blast furnace, rotating steel pipe to whose converter nose, open gate, inovulant will leak on molten iron uniformly, reaches optimal inoculation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of electro-smelting inoculation device, include funnel stand 10, staircase 11 it is provided with outside funnel stand 10, funnel stand 10 upper end is provided with funnel 3, the discharging end of funnel 3 is provided with steel pipe 5 diagonally downward by bearing 2, steel pipe pull bar 6 it is fixedly connected with on steel pipe 5, steel pipe pull bar 6 upper end is fixedly connected with horizontal turning handle 4, turning handle 4 other end rotates and is arranged on funnel stand 10, bearing 2 is arranged over flashboard 1, the laterally movable discharging end being arranged at funnel 3 of flashboard 1, inovulant 9 is added in funnel 3, steel pipe 5 is connected by bearing 2 with funnel 3, make the steel pipe 5 can be with 180 degree of rotations, the inovulant 9 that steel pipe 5 flows out enters electric furnace converter nose 8.
This inoculation device includes that funnel 3 is suspended in mid air by support 10, and gate 1 can control inovulant 9 and spill, and funnel is connected by bearing 2 with steel pipe 5, enables steel pipe 180 degree rotation.Steel pipe is connected by steel pipe pull bar 6 with turning handle 4, can be with hand rotation steel pipe to arbitrarily angled.
Operative employee climbs up platform from staircase 11, is poured into by inovulant 9 in funnel 3, rotates steel pipe 5 by swinging mounting 4, makes steel pipe face electric furnace converter nose 8.When electric furnace converter nose 8 taps a blast furnace, open rapidly gate 1, then inovulant passes through action of gravity, flows on electric furnace converter nose 8 by steel pipe 5, it is achieved the current-following inoculation of electric furnace processes.More than the 80% of whole inoculation process electric furnace to be reached tapping duration.
