Problems solved by technology

However, the actual temperature in the lower part of the blast furnace is much higher than this, and a large amount of high-temperature slag iron has infiltrated into the pores of the coke during the test, which is not conducive to the direct reduction reaction with molten iron, which affects the measurement of the high-temperature thermal properties of the coke, making the measurement results inaccurate. precise
Therefore, the experimental process of CRI and CSR measurement cannot well simulate the actual degradation behavior of coke in the blast furnace

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] like figure 1 As shown, a device for simulating the reaction of coke in a blast furnace is used to truly simulate the reaction of coke in the lower part of the blast furnace. The length is generally 4-5m); it includes corundum tube 5, corundum box 15, corundum sieve plate 11, corundum rod 7, column 8, metal cantilever 10;

[0033] The corundum box 15 has some first screen holes 13, and the corundum box 15 is fixed on the bottom of the corundum tube 5; coke is placed in the corundum box 15, and placing the coke in the corundum box 15 can prevent the coke from floating;

[0034] The upper pa...

Abstract

The invention discloses an apparatus for simulating the reaction of coke in a blast furnace. The apparatus comprises a corundum box, a corundum sieve plate and a corundum rod; the corundum box is provided with first sieve pores and is fixed to the bottom of the corundum tube; the upper portion of the corundum tube is provided with second sieve pores, the top of the corundum tube is provided with a corundum cover, and the corundum cover is connected with a stand column through a cantilever; the cantilever is respectively connected with a cantilever elevating mechanism and a cantilever rotating mechanism; the corundum rod traverses through the corundum cover, stretch into the corundum tube, and is connected with the corundum sieve plate in the corundum tube, and a corundum brush is arranged at one side under the corundum sieve plate; and the corundum rod is respectively connected with a corundum rod elevating mechanism and a corundum rod rotating mechanism. The invention also provides a method for simulating the reaction of coke in the blast furnace. The method can really simulate the top-down cracking process of coke in the blast furnace in order to accurately determine the high temperature performances of the coke; and the apparatus can really simulate the reaction of coke in the lower portion of the blast furnace in order to accurate determine the high temperature performances of the coke.

Description

technical field [0001] The invention relates to the technical field of blast furnace ironmaking in the metallurgical industry, in particular to a device and method for simulating coke reaction in a blast furnace. Background technique [0002] Coke is one of the main fuels for blast furnace smelting. Coke plays the role of exothermic agent, reducing agent and skeleton in the blast furnace, and also plays the role of part of carburizing agent. The quality of coke determines whether the blast furnace runs smoothly or not. [0003] Since the blast furnace is a "black box", complex physical and chemical reactions take place in different parts of the blast furnace from top to bottom. In the upper part of the furnace shaft, the charge begins to soften, and the iron-containing charge undergoes a reduction reaction with the upward blast furnace gas. In the 900-1000°C region in the middle of the furnace body, the carbon melting reaction is intense, and the iron-containing charge and...
