Embodiment 1

[0076] Ironworks of Laiwu Branch 5 # 1080m 3 Taking the refractory pouring model in front of the blast furnace as an example, the specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0077] Ironworks of Laiwu Branch 5 # 1080m 3 Take the refractory pouring model in front of the blast furnace as an example. The main ditch mold in front of the furnace is 4.3m long, the slightly inclined section is 2.9m, the inclined section is 0.8m, and the iron mouth section is 0.6m. The specific embodiment of the present invention is further described in conjunction with the accompanying drawings.

[0078] Adopting the principle of "wedge and segment", design the refractory pouring molds for the tapping channel series in front of the furnace. Use δ=8mm steel plate welding to make the main groove refractory casting mold (the length of the slightly inclined section is 2.9 meters, and the section size is determined by the A dire...

Abstract

The invention relates to the technical field of blast furnace production, in particular to a blast furnace front refractory casting mold and a casting method. Rapid casting molding and reutilization can be realized, and the blast furnace production requirement is greatly met. According to the blast furnace front refractory casting mold and the casting method, a wedged segmented model is designed, the purposes of rapid casting, forming and demolding are achieved through rapid water cooling and grease lubrication, the operation is easy, the cost is low, and similar accidents such as manual blockage of slag iron can be avoided.

Description

technical field [0001] The invention relates to the technical field of blast furnace production, in particular to a new blast furnace front refractory pouring mold and pouring method, which can be quickly cast and reused, and greatly meet the blast furnace production requirements. Background technique [0002] Raw materials such as iron ore, sinter, pellets, and coke are smelted in the blast furnace, and a series of physical and chemical reactions such as heat transfer, reduction, melting, and carburization occur successively. The blast furnace slag is formed with the ash in the fuel, and the slag and molten iron are released intermittently from the taphole, and the slag and iron are separated through the tapping ditch in front of the furnace. Among them, the tapping ditch in front of the furnace is a channel to guide high-temperature molten iron and slag, and it is subjected to high temperature, mechanical and chemical erosion of molten iron and slag liquid, so refractory m...
