Description

Production of casting nodulizer inoculant is with rushing into formula upset package

Technical Field

The utility model belongs to the technical field of nodulizer technical field for the foundry goods and specifically relates to a production of casting nodulizer inoculant is with punching-in formula upset package.

Background

The casting industry is one of the national basic industries, and products of the casting industry relate to military industry, civil use, aerospace, railways, automobiles, electric power equipment, infrastructure, various industrial and agricultural machinery manufacturing and the like. The casting parts are divided into colored casting parts and black casting parts, and the black casting parts are further divided into iron casting parts and steel casting parts.

Iron castings typically contain 2% to 4% carbon, and most of the carbon in the casting occurs as graphite in different shapes at room temperature. Iron castings are subdivided into nodular cast iron, gray cast iron, vermicular cast iron, etc., according to the different graphite morphologies. In the production process of the nodular cast iron, a nodulizer and a nodulizing process are necessarily used, and the nodulizer and the nodulizing process are usually added in an amount of 0.7-1.5% by mass, which are also core additives and processes for determining the performance of the nodular cast iron.

The nodulizer for casting is a ferrosilicon-based alloy, and other types of ferroalloys are used in some cases. The nodulizer is produced by using ferrosilicon, pig iron and magnesium ingot as main material and RE alloy, si-Ba, si-Ca, etc. as supplementary material. The conventional way of producing is to add all these materials into the furnace in the order of addition and then to tap them together and cast them into an ingot tray. Due to the particularity of magnesium, there are two ways of adding magnesium ingots.

One is to add the raw materials in advance, namely, the raw materials are added into the furnace in advance before being melted, and are smelted together with other raw materials. The first is that the reaction in the furnace is large in the later stage of smelting, the magnesium liquid is boiled rapidly, the worker is required to be skilled to operate rapidly, otherwise, the magnesium ingot in the furnace is lost, and even if the magnesium content of the product fluctuates greatly. Secondly, the production mode cannot carry out slag skimming in the smelting process, and all the oxidation slag formed in the smelting process is carried into the product.

And the other is post-magnesium adding, namely adding magnesium ingots after all other raw materials are smelted. It is common practice to bundle magnesium ingots together and use a robotic arm to press the magnesium ingots into the furnace. The instantaneous reaction in this way is too violent, the production environment is severe, and the damage to the furnace body is also large. In addition, the production efficiency is not high because the melting furnace is stopped to press magnesium.
