[0034] Casting process of a cast iron pot

[0035] Include the following steps:

[0036] Step S1, smelting molten iron: put cast pig iron broken into small pieces into the smelting furnace with metal elemental samarium and metal elemental neodymium in a mass ratio of 100:0.02:0.05, and continue heating to 1450°C. It is smelted into molten iron at high temperature, and at the same time, a mechanical stirring device is used to stir the molten iron at a speed of 100r / min, so that the molten iron is fully melted and even.

[0037] Step S2, pouring: Circulating air at 5°C is introduced into the sky above the smelting furnace, and the uniformly melted molten iron in it is slowly cooled to 1250°C, and then poured into a sand mold at a rate of 20L / s.

[0038] Step S3, preparation of nucleating seed crystal agent: quantitatively weigh raw materials, including 50 parts of ferric oxide, 20 parts of rutile, 10 parts of flake graphite, 10 parts of elemental silicon fine powder, pass throu...

[0044] Casting process of a cast iron pot

[0045] Include the following steps:

[0046] Step S1, smelting molten iron: Put cast iron broken into small pieces into the smelting furnace with metal elemental samarium and metal elemental neodymium in a mass ratio of 100:0.08:0.10, and heat up to 1500°C through continuous heating. It is smelted into molten iron at high temperature, and at the same time, a mechanical stirring device is used to stir the molten iron at a speed of 300r / min, so that the molten iron is fully melted and even.

[0047] Step S2, pouring: the circulating air of 15°C is introduced into the smelting furnace, and the uniformly melted molten iron in it is slowly cooled to 1350°C, and then poured into the sand mold at a rate of 50L / s.

[0048] Step S3, preparation of nucleating seed crystal agent: quantitatively weigh raw materials, including 150 parts of ferric oxide, 80 parts of rutile, 50 parts of flake graphite, 50 parts of elemental silicon fine powder, pa...

[0054] Casting process of a cast iron pot

[0055] Include the following steps:

[0056] Step S1, smelting molten iron: put cast pig iron broken into small pieces into the smelting furnace with metal elemental samarium and metal elemental neodymium according to the mass ratio of 100:0.05:0.07, and continue heating to 1475°C, It is smelted into molten iron at high temperature, and at the same time, a mechanical stirring device is used to stir the molten iron at a speed of 200r / min, so that the molten iron is fully melted and even.

[0057] Step S2, pouring: Ventilate circulating air at 10°C over the smelting furnace to slowly cool the evenly melted molten iron to 1300°C, then pour it into the sand mold at a rate of 35L / s.

[0058] Step S3, preparation of nucleating seed crystal agent: Quantitatively weigh raw materials, including 100 parts of ferric oxide, 50 parts of rutile, 30 parts of flake graphite, 30 parts of elemental silicon fine powder, pass through a 90-mesh sieve af...

Abstract

The invention discloses a casting iron pan and a casting process thereof.The casting process includes the steps of smashing pig iron, adding samarium and neodymium pure metal into a smelting furnace to be smelted at a high temperature, lowering the temperature of molten iron to be 1250-1350 DEG C, casting the molten iron in a sand mold, preparing a nucleation seed crystal agent, instantly putting in the nucleation seed crystal agent, conducting stirring to evenly disperse the nucleation seed crystal agent in molten iron till small micro-crystals appear, cooling the molten iron containing small micro-crystals till the molten iron is solidified, conducting demolding to obtain a rough product, conducting tempering on the rough product, taking out the product, grinding a tempered casting iron pan till the surface is smooth and presents metal luster to obtain the casting iron pan finished product, putting the finished product in a closed package bag, and storing the casting iron pan in a dry, ventilated and cool place.The casting iron pan is high in strength, plasticity and durability, the problems that the casting iron pan is long in forming time and not stable in performance are solved, and the additional value of the casting iron pan is improved.

Description

technical field [0001] The invention relates to the field of casting, in particular to a cast iron pot and its casting process. Background technique [0002] Cooking food is an important and warm part of family life, and the choice of cooking tools greatly affects whether the types of nutrients in food are healthy and rich in content. At present, there are many kinds of new pots and utensils in the kitchen supplies market, with complex functions and emerge in endlessly. There are a variety of stainless steel pots, ceramic pots, nano pots, fine steel pots, antibacterial pots and many other commodities. These overwhelming products largely ignore the most basic cooking functions of pots and pans. More and more people are gradually returning to using iron pots to cook food, which retains the fun and plot of cooking food to the greatest extent, and also improves the level of healthy living. [0003] There are many advantages to cooking food in an iron pan. On the one hand, the...
