Abstract
The utility model discloses a scrap iron preheating furnace with supporting use of high frequency electric stove, portal crane, whole furnace body divide into about two parts, and upper portion is the high temperature zone, the lower part is the preheating zone. One side of the upper part of the high-temperature zone is provided with a coal inlet, and the upper part of the high-temperature zone is provided with a high-temperature iron outlet. An outlet gantry crane is arranged above the high-temperature iron outlet. The lower part of the preheating zone is provided with a flue, and an inlet gantry crane is arranged below the flue. And a scrap iron inlet is formed in the lower part of the inlet gantry crane. The pusher assembly is positioned at the lower end of the furnace body. The furnace body is built by refractory bricks and sandy soil. Is a smelting device which saves electric energy and uses coal to replace electricity.
Description
The utility model relates to a kind of scrap iron preheating furnace, belongs to the smelting equipment of iron or steel.
At present, the minimills in the whole nation, it is most of that what use is high frequency furnace about 250kg, this electric furnace, power consumption is many, yields poorly, and electric energy expends too big.
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, provide a kind of with coal for electricity, the coal-fired preheating of scrap iron with high frequency furnace, the matching used scrap iron preheating furnace of straddle truck.
The purpose of this utility model is achieved in that the utility model comprises the total journey of kiln car pusher, and body of heater of the present utility model is divided into two parts up and down, and top is divided into the high temperature band, and the bottom is divided into the preheating zone.Top one side in high temperate zone has coal feed point, and the high temperature iron outlet is arranged at its top, and there is scrap iron outlet straddle truck the top of high temperature iron outlet.The bottom of preheating zone is provided with flue, and there is the import straddle truck below of flue, and the bottom of import straddle truck is provided with the scrap iron import, and the total journey of kiln car pusher is positioned at the lower end of body of heater, place vertical with body of heater.
The purpose of this utility model can also reach by following measure: with refractory brick or be incubated brick system and form, the body of heater external application sandy soil system of building forms in the body of heater of the present utility model.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
The utility model furnace superintendent is a 15-20 rice.During work, scrap iron (steel) piece is hung fire door (top of the total journey of kiln car pusher) with the import straddle truck, with entering preheating zone (5) in the total Cheng Dingjin stove of kiln car pusher, along with the preheating zone preheat temperature progressively is increased to high temperate zone, at this moment the steel scrap iron block becomes aglow, this iron block is moved in the incubator, hang in fusing in the coreless induction furnace (10) with scrap iron outlet straddle truck.Coal feed point of the present utility model is arranged on a side of top, high temperate zone (6) body of heater, and the combustion chamber is arranged on the upper end of body of heater, the top of high temperate zone (6).All smog in the combustion process are got rid of through flue (4).
The utlity model has compared to existing technology following advantage: power consumption is low, and power consumption descends 70%; Output height, the daily output increase 2-3 doubly; Profit height, profit growth 3-4 are doubly; For electricity, take full advantage of the energy with coal, alleviate the electric energy tensity; The furnace binding simple and durable, invest little, instant effect, long service life, easy to maintenance.
Claims (2)
1, a kind of and high frequency furnace, the matching used scrap iron preheating furnace of straddle truck, comprise the total journey of kiln car pusher (1), it is characterized in that: whole body of heater is divided into two parts, its top is divided into high temperature band (6), the bottom is divided into preheating zone (5), top one side in high temperate zone (6) is provided with coal feed point (7), the top in high temperate zone (6) is provided with high temperature iron outlet (8), the top of high temperature iron outlet (8) is provided with scrap iron outlet straddle truck, the bottom of preheating zone (5) is provided with flue (4), the below of flue (4) is provided with import straddle truck (3), and the bottom of import straddle truck (3) is provided with scrap iron import (2), and the total journey of kiln car pusher (1) is positioned at the lower end of body of heater.
2, scrap iron preheating furnace according to claim 1 is characterized in that in the body of heater with refractory brick or is incubated brick system forming, and the body of heater external application sandy soil system of building forms.
