Problems solved by technology

Due to the segmented knotting and the large gap between the magnesia particles in the knotting layer, there are certain defects in the knotting layer between the upper ring and the base, which may easily cause the knotting layer to fall off during the baking process and affect the ingot. The knotting quality of the mould, and the normal use of the ingot mould, cannot be guaranteed

Embodiment Construction

[0015] Such as figure 1 Shown is a vanadium-iron ingot mold for tilting smelting furnaces provided by the present invention, which has good protection effect and can effectively ensure the normal use of the ingot mold, and a knotting method for the vanadium-iron ingot mold. The vanadium iron ingot mold includes an upper ring 1 and a base 2, the upper ring 1 is detachably mounted on the base 2, and the vanadium iron ingot mold also includes an integrated protective refractory layer 3, The inner walls of the base 2 and the upper ring 1 are covered by the integral protective refractory layer 3 . The knotting method adopts the knotting sequence of the magnesia knotting layer 4, the transition layer 5, and the magnesia corundum knotting layer 6 from bottom to top to complete the knotting of the integrated protective refractory layer 3 at one time. Work. The present application improves the integrated protective refractory layer 3 by improving the knotted layers originally arrange...

Abstract

The invention discloses a vanadium iron ingot mould for rollover-type smelting furnaces and a knotting method of the vanadium iron ingot mould and belongs to the technical field of metallurgical production ancillary equipment design and manufacture. The vanadium iron ingot mould comprises an upper ring and a base, the upper ring is detachably and fixedly mounted on the base, the vanadium iron ingot mould further comprises an integral protective flame retardant layer, and the inner wall of each of the base and the upper ring is coated with the integral protective flame retardant layer. The knotting method includes sequentially knotting a magnesia knotting layer, a transition layer and finally magnesia corundum knot layer from bottom to top, and knotting of the integral flame retardant layer is completed in one step. The vanadium iron ingot mould for the rollover-type smelting furnaces and the knotting method of the vanadium iron ingot mould have the advantages of good protective effect, and normal use of the ingot mould can be effectively guaranteed.

Description

technical field [0001] The invention relates to an iron vanadium ingot mold, in particular to an iron vanadium ingot mold used in a tilting smelting furnace, and belongs to the technical field of design and manufacture of auxiliary equipment for metallurgical production. The invention also relates to a knotting method for the ferrovanadium ingot mould. Background technique [0002] After the smelting process of ferrovanadium smelting in the tilting furnace is completed, the ferrovanadium should be poured into the ingot mold to cool down, and then the mold removal, water quenching, crushing and packaging should be carried out after cooling. Because the iron-tapping temperature of ferro-vanadium smelting is relatively high, generally reaching a temperature of about 2000°C, the ingot mold containing the molten vanadium-iron alloy is extremely important. At present, the iron-vanadium ingot mold is composed of an upper ring and a base. In order to ensure the use effect of the in...
