Novel ferroalloy continuous casting machine

Abstract

The invention discloses a novel ferroalloy continuous casting machine, and is applied to the field of ferroalloy production facilities. The novel ferroalloy continuous casting machine includes a rack,a head star wheel, a heat bent rail, an upper rail, a tail rail, a tail star wheel and a lower guide rail, wherein the head star wheel, the heat bent rail, the upper rail, the tail rail, the tail star wheel and the lower guide rail are sequentially arranged on the rack in a circular sealing mode; a plurality of freestanding trolley bodies are arranged on the guide rail; each trolley body includesa panel ingot mould, a transition part, a shaft sleeve and wheels, wherein the upper and lower faces of the panel ingot mould are symmetrically sunken inwards. The invention aims at eliminating the disadvantages of traditional shaping modes of pit casting, cast iron ingot mould casting and plate-chain pig machines and having the advantages of the better technical scheme. Particularly, compared with the traditional modes, the casting performance of the novel ferroalloy continuous casting machine is improved at all aspects; the novel ferroalloy continuous casting machine has the significant advantages that the yield and the quality are high, the labor strength is low, multispecies casting is achieved, centralized treatment is conveniently conducted on fume and gas, the occupied area is small, maintenance is convenient, the mould-iron ratio is large, and the ingot mould is not easily damaged by fire.

Description

technical field [0001] The invention belongs to the field of ferroalloy production facilities, and in particular relates to a novel ferroalloy continuous casting machine. Background technique [0002] There are three main methods of traditional ferroalloy casting: [0003] 1. Pit casting: the advantage is large processing capacity at one time and fast casting speed; the disadvantage is that it occupies a large area, the slag in the iron is not easy to separate, and the quality is poor; Severe throwing and flying dust; the varieties that can be cast are limited, and some products cannot be cast in pits due to quality requirements; the site is large, the unorganized emission of smoke and steam is large, the investment in dust removal equipment is huge and the effect is not ideal; in the pursuit of lean management and environmental protection Under severe social conditions, this method faces elimination. [0004] 2. Cast iron ingot mold casting: the advantage is that the prod...

[0003] 1. Pit casting: the advantage is large processing capacity at one time and fast casting speed; the disadvantage is that it occupies a large area, the slag in the iron is not easy to separate, and the quality is poor; Severe throwing and flying dust; the varieties that can be cast are limited, and some products cannot be cast in pits due to quality requirements; the site is large, the unorganized emission of smoke and steam is large, the investment in dust removal equipment is huge and the effect is not ideal; in the pursuit of lean management and environmental protection Under severe social conditions, this method faces elimination

[0004] 2. Cast iron ingot mold casting: the advantage is that the product quality is good; the disadvantage is that the output of a single ingot mold is small. With the enlargement of ferroalloy submerged arc furnaces, a large number of ingot molds are required for one tapping, which occupies a large area; most ingot molds are cast The molten iron ladle needs to be moved back and forth, and the flue gas during casting cannot be handled

[0005] 3. Plate chain cast iron machine: the advantage is that the finished product does not need to be broken, the production line is short, and the production continuity is good; when pouring iron, it is cast at a fixed point, and the flue gas is easy to handle; the disadvantage is that the output of the traditional plate chain cast machine is small. The large-scale submerged arc furnace requires a one-time treatment of more than 30 tons of molten iron, which is difficult for traditional iron casting machines; at the same time, there are too many moving parts, the force of the plate chain is large, and the maintenance of multiple parts is difficult, which makes it difficult to enlarge the equipment; The mold-iron ratio of the ingot mold is small, the temperature of the ingot mold is high, the heat dissipation is slow, the service life of the ingot mold is short, and the cost per ton of product is high; the surface of the ingot mold is a groove structure, and the steps between the grooves are easy to be burned. Molding is difficult, yield rate becomes low
