The thermal strength of coke (what is the thermal strength of coke)

The proportion of the coal pile into the coke oven with the coke thermal strength machine is basically constant. To achieve the purpose of improving the strength density, we can only find ways the coking mechanism coking process. the perspective of coking mechanism, the process of coal softening→melting→expansion→solidification→shrinkage→coking is inevitable during the dry distillation process. In this process, as long as the coal has good melting cohesiveness, the solid material gaps are filled, the solid liquid materials are fully attached, the density strength can be improved. the perspective of production technology, if the coking process can be controlled reasonably, it will also have a greater impact on porosity. Therefore, it can be seen that the nature of blended coal is an internal factor that affects the quality of coke, is the basis; the production process is an external factor that affects the quality of coke, it is a guarantee. Only by reasonably adjusting the internal factors controlling the external factors can the thermal strength of the ideal coke product be obtained.

What is the relationship between the thermal strength thermal reactivity of coke? The coke thermal strength analysis coke reactivity tester measures the two indicators of coke reactivity post-reaction strength. The thermal reactivity strength of coke are important indicators of coke's high-temperature metallurgical performance. The coke with good reactivity can indirectly reduce the middle upper part of the blast furnace release a certain amount of heat, which is beneficial to reduce the coke ratio. Poorly reactive coke makes the middle lower parts of the blast furnace directly reduce too much absorbs a lot of heat, which leads to an increase in the coke ratio an increase in the cost of blast furnace smelting. The strength index after the coke reaction directly reflects whether the coke can still support the framework under the huge pressure of the lower column of the blast furnace. Therefore, the thermal reactivity post-reaction strength test of coke is an important means to test the quality of coke, it can provide important production operation basis for the blast furnace smelting process. The thermal strength of coke is a mechanical strength index reflecting the thermal performance of coke. It expresses the ability of coke to resist crushing abrasion when subjected to thermal stress mechanical force at the same time under the temperature atmosphere of the use environment. Coke is an indispensable fuel for the traditional blast furnace ironmaking process. In recent years, with the development of blast furnace fuel injection technology, the coke ratio has continued to decline, the impact of coke quality on blast furnace smelting has become more more obvious, which has become one of the factors restricting the development of blast furnace production. Coke used for blast furnace smelting usually needs to meet the quality requirements of three aspects such as composition, particle size strength, such as high fixed C content, low ash content, low content of harmful elements, uniform particle size of 40-60mm, high cold strength. In order to ensure the ability of the coke to resist crushing abrasion under the temperature atmosphere conditions in the furnace, the coke is also required to have a certain thermal strength (reaction strength weak reactivity)
