Description
Technical field
The invention belongs to metallurgical technology field, disclose the device and method of a kind of electric stove metal bulk cargo continuous feeding and preheating.
Background technology
A kind of important method for making steel of electric furnace steel making, it can consume a large amount of electric energy by arc-melting steel scrap metal in smelting process.Waste steel for electric furnace continuous charging and preheating technology are the important subitem technology of of electric furnace steel making, it can be saved electric energy in a large number and reduce flue-gas temperature and dust discharge amount wherein, and can stablize the electric arc smelting of electric furnace and reduce the noise of electric furnace work, be a kind of energy-conserving and environment-protective new technology.Popular in the world foreign technology mainly is based on shaft furnace technical development COSS technology of getting up and the CONSTEEL technology of vibrating continuous charging at present, the COSS technology has the good technical index, but the development foundation based on the electric furnace shaft furnace makes the furnace equipment height strengthen, factory building is increased, feed way is interrupted reinforced, also there are environmental protection treatment problems such as dioxin in addition, are tending towards stagnating so it is promoted the use of.And based on the vibration continuous charging the CONSTEEL technology be a kind of horizontal continuous-feeding technology, can realize the smelting of electric furnace stabilising arc, environmental protection and consumption of electrode reduce, can reduce the production process expense of electric furnace greatly, but this mode has only upper materials to be heated owing to steel scrap, so the steel scrap pre-heat effect is not good, and because vibrating feed has the high temperature that a large amount of moving components is added flue gas, the plant maintenance amount of this system is bigger, and Mechanical Reliability is relatively low.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the apparatus and method of a kind of electric stove metal bulk cargo continuous feeding and preheating are provided.This device metal feed roller fore-warmer tank and horizontal plane tilt, the low side of metal charge cylinder fore-warmer tank is inserted into the inlet short distance fit of stove vibratory feed, going into the stove vibratory feed is connected with electric furnace A perforate, lower near end position, the high-end cover of metal charge cylinder fore-warmer tank is shared into groove vibrating transportation and air seal set, both short distance fits.
This device has adopted vibra shoot, cylinder heating tank and banded plate chain are carried compound mode, make full use of transportation characteristics separately, comparing whole vibrating transportation with the CONSTEEL technology compares, pre-heat effect is good, vibration equipment is little, the mass transport amount is big, apparatus arrangement length obviously shortens, factory building can be lacked, and power of motor consumption reduces in material conveying process, because the plate chain is carried tiltable and crooked the conveying, helps improving the operating rate of magnetic disc suspending to the steel scrap lifting, in addition, these apparatus and method are more effective to metalliferous material (as the sponge iron) conveying and the preheating of pelletizing shape.
The present invention realizes in the following way:
Metal charge (or steel scrap) is loaded onto the plate chain by magnetic disc suspending (or miscellaneous equipment) and is subjected to material conveyer, for guaranteeing reinforced mass flow, the plate chain is subjected to material conveyer that enough length will be arranged, and for improving the operating rate of magnetic disc suspending, the plate chain is installed to reduce the magnetic disc suspending hoisting depth by the material conveyer tiltable in addition.The plate chain is delivered into steel scrap or metal charge in the inlet slot of groove vibrating transportation and air seal set by material conveyer, the material outlet of going into groove vibrating transportation and air seal set inserts short distance gap, the porch fit of metal charge fore-warmer tank, for guaranteeing that metal charge is at porch smoothness jam not, the inlet base plate of going into groove vibrating transportation and air seal set will be higher than a wide segment distance and close center line in the metal charge fore-warmer tank, so that steel scrap or metal charge have not jam of big diffusion space below the porch, going into groove vibrating transportation and air seal set can be consistent with metal charge fore-warmer tank inclination angle, also can be different.Going into groove vibrating transportation and air seal set is installed on the travelling carriage, travelling carriage is connected with an oil cylinder, oil cylinder promotes travelling carriage, make into groove vibrating transportation and air seal set can be as required with steel scrap fore-warmer tank short distance gap fit (duty) or throw off (service mode) fully, the effect of going into groove vibrating transportation and air seal set is that the metal charge vibrating transportation that will send here by material conveyer enters the metal charge fore-warmer tank, extract hot flue gas from the metal charge fore-warmer tank, and the inlet cold air of the metal charge of this device and the hot flue gas of outlet taken out mouthful carry out air-flow and dynamically intercept, the metal charge fore-warmer tank adopts the mode of reversing or rotating continuously around its axis steel scrap or metal charge to be transported to the low side of steel scrap fore-warmer tank, in this process, metal charge rolls in the metal charge fore-warmer tank and hot flue gas carries out heat exchange, and the metal charge of cold conditions obtains preheating.The high-end material inlet of going into the stove vibratory feed of inclination is inserted in metal charge fore-warmer tank low side outlet, both short distance gap fits, and the low side material outlet of going into the stove vibratory feed stretches into the perforate on the electric furnace, and metal charge or steel scrap vibration are added electric furnace.Going into stove vibration conveying device is installed on the travelling carriage, travelling carriage is connected with an oil cylinder, oil cylinder promotes travelling carriage, make into the stove vibratory feed can be as required with electric furnace short distance gap fit (duty) or throw off (tapping or service mode operation) fully, this design has a very large advantage, it can be so that the reinforced perforate on the electric furnace needn't be left on the axis of rotation that electric furnace fascinates, and the wide adaptability of electric furnace can be used for the transformation of various medium-and-large-sized electric furnaces.Above-mentionedly go into stove vibratory feed, metal charge fore-warmer tank, go into the groove vibrating transportation and air seal set is integrated and annex is installed on the locomotive, dress locking device and oil cylinder on the locomotive, the dress locking device makes locomotive and said mechanism can accurately locate and smooth working in working order, oil cylinder can make locomotive big apart from breaking away from electric furnace, so that be that equipment is safeguarded fast and the replacing parts create conditions.Above-mentioned travelling carriage and locomotive adopt hydraulic oil cylinder driving, its objective is and utilize the original hydraulic system of electric furnace, if adopt other kind of drive, drive and also are fine as wheel driving, electric fluid cylinder.
The compound mode that the present invention adopts vibrating transportation, the conveying of cylinder chute type and the material feeding of plate chain to carry, realize that steel scrap or metalliferous material are to the continuous charging of electric furnace and utilize the discarded flue gas of high temperature to carry out preheating to material, having the production cost of energy-saving and environmental protection, reduction electric furnace smelting, is a kind of energy-conserving and environment-protective new technology that has promotional value on electric furnace.
