Abstract

The invention relates to the field of metal smelting, in particular to an open-type scrap steel heating device and method capable of impurity pretreatment. The technical problems that an existing furnace heating mode is closed heating, dangers are great, and personnel suffocation and explosion are easily caused are solved. According to the technical implementation scheme, the open-type scrap steel heating device capable of impurity pretreatment comprises a first connecting frame, a second connecting frame and a scrap steel heating mechanism; the second connecting frame is arranged behind the first connecting frame; and the scrap steel heating mechanism is connected with the upper portion of the first connecting frame and the upper portion of the second connecting frame, and is used for heating scrap steel. According to the open-type scrap steel heating device and method capable of impurity pretreatment, an open-type scrap steel heating container is adopted, the problem that in the prior art, due to the fact that scrap steel is heated in a sealed mode through a furnace, personnel suffocation and explosion are easily caused is solved, the scrap steel is recycled, the proportion of molten iron is greatly reduced, carbon emission caused by iron ore is reduced, thus the production cost is reduced, the environment is protected, and coal gas accumulation is prevented.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an open scrap steel heating device for sundry pretreatment and a method thereof. Background technique [0002] Scrap preheating technology is the current energy saving and emission reduction in the steelmaking industry, reducing the consumption of iron ore (hot metal), and greatly increasing the proportion of scrap steelmaking is a major trend. [0003] As a renewable resource, scrap steel has low natural consumption and high utilization rate. During steelmaking, exchanging an appropriate amount of scrap steel for iron ore is conducive to reducing carbon emissions and controlling costs. When the existing kiln preheating device preheats scrap steel, the kiln works under relatively airtight conditions, which is likely to cause an explosion, and at the same time, there is a danger of suffocation for workers entering the kiln. [0004] For this reason, we propose a new type of furnace-...
