Automatic material sliding device and smelting furnace

Abstract

The invention relates to an automatic material sliding device and a smelting furnace using the automatic material sliding device. The automatic material sliding device comprises a material bearing chute and a discharging chute pipe provided with a material sliding control mechanism, and the material sliding control mechanism comprises a gate plate, a force arm rod and a reset unit. The force arm rod is arranged on the discharging chute in a rotatable and penetrating mode and comprises an in-pipe rod section located in the discharging chute pipe and an outside-pipe rod section located outside the discharging chute pipe. The gate plate is installed on an inside-pipe rod section, and the reset unit is connected with the outside-pipe rod section and has a first state in which a circulation passageway of the discharging chute pipe is closed through the gate plate and a second state in which the gate plate follows up when the gate plate is impacted by materials and drives the power arm rod to rotate. While the material sliding function of the automatic material sliding device is guaranteed, smoke in the furnace can be prevented from overflowing or external air can be prevented from entering the furnace under the condition that feeding is not conducted, and automatic opening and closing of the gate plate can be achieved. When the automatic material sliding device is applied to the smelting furnace, stable and reliable operation of the smelting furnace can be guaranteed, and smelting flue gas is prevented from polluting the environment or the external air is prevented from entering the furnace to influence production.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to an automatic material slide device and a smelting furnace using the automatic material slide device. Background technique [0002] To make good steel, you must first make good slag, and the completion of almost all steelmaking tasks is closely related to slag. The slag can remove harmful elements such as phosphorus and sulfur in the steel charge, and can also keep warm, prevent molten steel from peroxidation, reduce the burning loss of beneficial elements, and can absorb floating non-metallic inclusions and reaction products in molten steel, stabilizing arc combustion , improve the thermal efficiency of the furnace, protect the furnace lining, etc. [0003] The sources of slag mainly include slagging materials added, such as lime, dolomite, fluorite, etc., as well as soil, sand, and other oxidation products of silicon, manganese, phosphorus, sulfur an...

AI Technical Summary

Problems solved by technology

In addition to the slagging material that comes with the charge, it is also necessary to add the rest of the slagging material during the smelting slagging process. Generally, it slides from the opening of the furnace cover into the furnace through a slide pipe, but it needs to be closed when the slide is not needed. The chute channel prevents flue gas from overflowing, causing heat loss in the furnace and air pollution in the workshop, deteriorating the working environment, or allowing outside air to enter the furnace from the chute channel, accelerating electrode oxidation and increasing the workload of subsequent dust removal equipment
