Low-carbon manganese-silicon alloy casting ingot mold

Technical Field

The utility model relates to an ironmaking equipment field, concretely relates to ingot mould is pour to low carbon manganese silicon alloy.

Background

Steel is an indispensable important resource in both floor construction and railway construction. There are basically two processes for manufacturing steel, one of which is important for producing pig iron, and blast furnace iron-making is the iron-making process mainly used in china. In recent years, the development of the blast furnace iron-making technology in China has been rapidly advanced, and the automation, the large-scale and the high-efficiency are continuously advanced, so that the purposes of low cost, low consumption and low pollution are achieved.

Blast furnace iron making refers to a method for continuously producing liquid pig iron (such as ferro-silico-manganese) in a vertical reactor, i.e. a blast furnace, by using coke, iron-containing ore (natural rich lumps, sintered ores and pellets) and flux (limestone and dolomite). It is an important link in modern steel production; the modern blast furnace iron making is improved and developed by an ancient shaft furnace iron making method. Although many iron-making methods are researched and developed in various countries in the world, the method is relatively simple in process, high in yield, high in labor productivity and low in energy consumption, so that blast furnace iron-making is still the main method for modern iron-making, and the yield of the method accounts for more than 95% of the total pig iron production in the world.

In the blast furnace, iron-containing ores are heated and melted, so that molten iron is separated to form an iron ingot, and in the process of preparing the iron ingot, the molten iron is poured into a molten iron mold and is cooled to separate the molten iron mold from the iron ingot, so that the iron ingot can be formed.

Each iron ingot with large volume can weigh dozens of tons or even dozens of tons, when the molten iron mold is separated from the iron ingot, the mold is reversed, the iron ingot and the molten iron mold can be separated, the separated mold is transferred to a storage area to be placed together in order, the whole preparation process of the iron ingot is completed, and finally, forging and pressing are carried out, so that a blank meeting the requirements on density and shape is formed for sale.

The first problem is that because the temperature of molten iron is high, when the molten iron is poured into the molten iron mold, the mold is easily burnt out, and the current method is that a layer of refractory bricks is built on the inner wall of the inner molten iron mold, but the refractory bricks are refractory, but for an iron works, the use of high frequency makes the refractory bricks not durable, the quality is poor, the refractory bricks are still not durable, the refractory bricks need to be frequently built by technicians, the building process takes time, and the construction period is greatly influenced; secondly, the reverse buckling of the iron mold after the iron mold is hoisted is difficult, and needs to be carried out by a plurality of technicians, sometimes the iron mold and the iron ingot are firmly adhered (due to the damage of a fire-resistant layer), the iron ingot can be separated from the iron mold only by knocking the iron mold slowly, which is an important factor influencing the efficiency, and after the iron ingot is separated, the iron ingot still needs to be hoisted and transported with great effort.

In summary, in the current mode, there are many inconveniences, and many times, it is difficult to deliver the order of the customer as scheduled, which greatly affects the business volume and the credit of the enterprise, so optimizing the whole process is one of the important measures for the benign development of the enterprise.
