Problems solved by technology
[0009] 1. The basic expenditure and cost of methods 1 and 2 are large, and it takes a long time from the start of construction to production
[0010] 2. The production and casting of steel requires a lot of labor
[0011] 3. The production capacity of steel smelting and casting equipment is insufficient, and its effective utilization rate is low, about 80%
[0012] 4. The process of obtaining castings requires high power consumption
[0013] 5. The cost of castings is high, and it needs to be processed from blast furnace-converter-steel ingot or from blast furnace-electric furnace-steel ingot
[0018] 2. The wear of the gate plug on the slag belt and the wear of the gate plug head
[0020] 4. The connecting fork between the push rod and the gate plug machine is bent and deformed
[0022] 1. The result of baffle gate is complicated and the price is high
[0023] 2. Opening is a complex working method, and the channel of the baffle gate needs to be filled
[0025] 4. The air is sucked between the hand plates of the baffle type gate and the quality of the metal (steel) is reduced
) The disadvantage of this device is that the liquid metal is not refined and vacuum treated, and its casting depends on the liquid column height of the liquid metal in the mold

Embodiment Construction
[0037] In order to achieve the above-mentioned technological achievements, the process from iron to steel castings does not use mechanical devices, but is completed by a unique KOMKOB steel casting combined machine ( figure 1 ). The main working means is to use gas. The composition of KEMKERB Steel Casting Combined Mill is as follows:
[0038] Casting ladles or ladles, intermediate ladles or ladles, and molds. In this method the cast iron ladle is supplied with molten iron. In small factories, it is possible to see that the combined cast steel unit of KOB and the Romant process are used together. Refining molten iron in cast iron ladles using gas and universal gas components. The gas components in the ladle perform the functions of sprue plugs, dosing feeders and tuyeres. The gas component is made up of two devices, the gas cap and the first gas pipe 11, and the gas pressure is regulated by a blower.
[0039] The air cap device also completes the functions of gate, meter...

The claimed inventions relate to metallurgy and involve the production of steel from cast iron. The apparatus comprises a ladle (1) in which liquid cast iron (2) is blasted with oxygen via bottom tuyeres (4) and a "gas dome" device (6) until steel of the required chemical composition is produced. The steel is cast via a "gas pipe" device (11) having a pouring nozzle into an intermediate ladle (9) with the steel simultaneously being refined with gas. The steel is recast into the crystallizer of a machine for the continuous casting of blanks (14), with simultaneous and continuous degassing. The steel can be produced without using electric furnaces or converters.
Description
technical field [0001] The present invention relates to methods and equipment for continuous casting of steel. Background technique [0002] The main technical processes of steel production and casting are as follows: [0003] a. Large metallurgical plant [0004] 1. Blast furnace - converter - steel ingot [0005] 2. Blast furnace - electric furnace - steel ingot [0006] b. Small factory [0007] 3. Electric furnace - smelting of high-tech cast iron ladle - steel ingot [0008] Modes 1 and 2 are different from mode 3. The production technology process of steel and the casting of steel are known. The disadvantages are as follows: [0009] 1. Modes 1 and 2 require a large amount of basic expenditure and cost, and it takes a relatively long period from the beginning of construction to putting into production. [0010] 2. The production and casting of steel requires a lot of labor. [0011] 3. The production capacity of steel smelting and casting equipment is insufficie...
