With the continuous large-scale of blast furnaces of iron and steel enterprises, the coke quality requirement is higher and higher, and the high-quality coking coal resource is lacking increasingly, so that the coal blending pressure of the coking industry is increased, and the prediction and control of the coke quality become the key problems of coking production. In order to stabilize the coke quality, control the raw material cost, expand the coking raw material coal range and formulate a reasonable coking and coal blending process, some process indexes considered in the traditional coal blending method can not meet the requirements of coal blending production, so that the search for an experimental coke oven capable of truly simulating the coke quality of the coke oven is necessary.
Practice proves that one important function of the experimental coke oven is to use the cokes to predict the cold strength, the reactivity at 1100 ℃ and the strength after reaction of the cokes produced by the experimental coke oven, and because the coke quality of the experimental coke oven is easy to establish a correlation with the coke quality of the coke oven produced by the experimental coke oven, the result of the coke oven produced can be predicted according to the experimental data of the experimental coke oven, so that the aim of guiding coking production is fulfilled. At present, the experimental coke ovens adopted in the laboratories of various domestic coke-oven plants mostly adopt a dry distillation coking mode of coal blending samples under the condition of no load (natural expansion of a colloid), so that the coke refined by the experimental coke ovens has lower density, excessive coke foam, larger cold strength, 1100 ℃ reactivity and strength index deviation after reaction compared with a large coke oven, the physicochemical properties of the coke between the two can only be compared and measured by correlation, the reliability of the detection result is low, and the requirement of guiding coking production is difficult to meet.

The device can simulate the pressure of the coal blending in the carbonization chambers of the coke ovens with different volumes in the carbonization process of carbonization and coking, and can control the atmosphere pressure of the coal blending sample in the carbonization chamber in the whole process of high-temperature carbonization, thereby truly simulating the process conditions of the coke ovens to finish the high-temperature carbonization process. But adopt a set of simulation experiment device can't carry out the continuous experiment, work efficiency is not high.
