Abstract
The utility model discloses an unloading pipe for inside electric arc furnace, including heat -resistance stainless steel pipe and heat -resisting corrosion resistant plate ring, evenly weld a plurality of heat -resistance stainless steel gusset at the position that welds of heat -resistance stainless steel pipe and heat -resisting corrosion resistant plate ring, there are the suit a plurality of zhi zhuzhuan heat -resistance stainless steel muscle of several cyclic annular heat -resistance stainless steel muscle evenly to weld at heat -resistance stainless steel outside of tubes wall to use column heat -resistance stainless steel muscle to pack refractory material as the skeleton at heat -resistance stainless steel outside of tubes wall, the unloading hole department on the electric arc furnace bell is installed to the inside unloading pipe of electric stove when using, the concentric cooperation of metal unloading pipe with electric arc furnace bell top is managed to the heat -resistance stainless steel, and all the other parts of unloading pipe are hanged in the electric arc furnace, can effectively resist the high temperature that produces when the thorn is angered and not damage, strengthen the shock -resistant ability that the unloading was managed, carry high mechanical strength, prolong the life of unloading pipe, the reduction maintenance cost improves production efficiency.
Description
Technical field
The utility model belongs to metal and alloy smelting field, is specifically related to a kind of tremie pipe for electric arc furnaces inside.
Background technology
When using closed or semi-enclosed three-phawse arc furnace metal smelting or ore, take electrode to insert the arc-covering slag operation of furnace charge, tremie pipe is distributed in electrode surrounding, for adding furnace charge in stove.In electric arc furnaces, load melting fastest in the middle of three electrodes.The reasons such as point are crossed due to misoperation or charge level, when charge level declines too fast, not reinforced in time herein, high temperature gas flow or electric arc are broken through the weak bed of material and produce the fiery phenomenon of thorn, make the tremie pipe of the metal material of surrounding them just be subject to serious melting loss in the short period of time, after tremie pipe melting loss, have to manually smash stove or blowing out replacing tremie pipe, labour intensity is large and safety coefficient is low, changes accessory frequently, causes cost higher, and during replacement cost, reduce production efficiency.
Utility model content
The utility model, for the deficiency in background technology, aims to provide one in high temperature environments not by melting loss, and has the tremie pipe for electric arc furnaces inside of enough mechanical strengths.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: Heat-Resisting Stainless Steel Tube and the boxing of heat-resistance stainless steel plate are connected together, and reinforce at the some heat-resistance stainless steel gussets of weldering position uniform welding, and at Heat-Resisting Stainless Steel Tube outer wall uniform welding some pillar-shaped heat-resistance stainless steels muscle, and outside column heat-resistance stainless steel muscle even suit welding number Zhi Huanzhuan heat-resistance stainless steel muscle to install mould additional be auxiliary, between Heat-Resisting Stainless Steel Tube outer wall and mould with column heat-resistance stainless steel muscle for skeleton filling fire resisting material is formed.
During use, described heat-resistance stainless steel plate ring is fixed on arc furnace by screw and covers, and make the metal tremie pipe concentric fit above Heat-Resisting Stainless Steel Tube and arc furnace cover, tremie pipe remainder is suspended from electric arc furnaces, the upper inside wall of tremie pipe is inlayed and the heat resisting pipe of electric furnace external metallization tremie pipe with internal diameter, mainly bears bulk material from the mechanical shock produced when exceeding and fall and wearing and tearing; Employing refractory material casting is shaping, and pre-buried heat-resistance stainless steel reinforcing bar is reinforced refractory material in inside, and strengthening is high temperature resistant, anti-further melts ability; The discharge end side of tremie pipe sets a height as 200mm
-the semicircle opening of 300mm, and by opening direction counter electrode, furnace charge is tumbled to electrode direction.
Beneficial effect: refractory material effectively can be resisted the high temperature of generation when stinging fire and not damage, with heat-resistance stainless steel reinforcing bar for skeleton improves mechanical strength, enhance the shock-resistant ability of tremie pipe, thus extend the service life of tremie pipe, reduce and manually smash stove or blowing out maintenance rate frequently, reduce the maintenance cost of electric arc furnaces, ensure production safety, enhance productivity.
