Embodiment Construction

[0011] Such as figure 1 , 2 As shown, a regenerative gas-fired coal-fired scrap steel melting furnace includes a base 1, a furnace body 2, and a feeding channel 16. The base 1 is located below the furnace body 2, and the feeding channel 16 is located above the furnace body 2. The feeding channel 16 communicates with the furnace body 2, the furnace body 2 is provided with a tap hole 18, the side of the furnace body 2 is provided with a heating device, the heating device communicates with the furnace body 2 through the burner nozzle 14, and a high-voltage electronic point is set in front of the burner nozzle 14 Musket 15.

[0012] The body of furnace 2 is cube-shaped or spherical.

[0013] The heating device is a pulverized coal spray gun 9 .

[0014] The heating device is a gas main pipe 10 and a gas nozzle 13 communicated through a gas shut-off valve 11 .

[0015] The feeding channel 16 is an inverted cone, and a feeding port 17 is arranged on the upper part of the feeding...

Abstract

The invention relates to iron and steel smelting equipment, in particular to a heat accumulating type fuel gas and fuel coal steel scrap melting furnace which solves the problem of steel scrap smelting. The technical scheme is as follows: the Heat accumulating type fuel gas and fuel coal steel scrap melting furnace comprises a base, a furnace body and a charging channel. The base is located belowthe furnace body, the charging channel is arranged above the furnace body and communicates to the furnace body, a tap hole is formed in the lower part of the furnace body, a heating device is arrangedon the side face of the furnace body and communicates to the furnace body through a nozzle spray head, and a high voltage electronic burning torch is arranged in front of the nozzle spray head. According to the system, steel scrap is added intermittently and is heated continuously to be melted, and molten steel is discharged intermittently. According to the heat accumulating type fuel gas and fuel coal steel scrap melting furnace, the steel scrap can be melted with a low cost: the cost is saved by 400-500 yuan/ton compared with that of directly using an electric furnace.

Description

technical field [0001] The invention relates to iron and steel smelting equipment, in particular to a regenerative gas-fired coal-fired scrap steel melting furnace. Background technique [0002] With the development of my country's national economy, a large number of equipment made of steel has gradually reached the phase-out period, especially scrapped automobiles and mechanical equipment, and more and more scrap steel is produced in the machining industry. For example, all kinds of waste equipment, steel structural parts, "scrap" locomotives, vehicles, rails, automobiles, ships, tools, appliances, etc. The annual production of scrap steel can account for 25-30% of the total steel output in industrially developed countries. Making full use of scrap steel is also one of the important ways to reduce pollution and reduce the amount of iron and steel ore smelting. In order to fully and effectively utilize steel scrap, it is an inevitable trend for all developed industrial cou...
