1 Question raised

Our company currently has a 20kg test coke oven, which is equipped with a top-loading coal coking test. However, it can be carried out frequently during the tamping coking test, and only a relatively original iron box test can be taken. The coal is tamped in the iron box manually After installed in the carbonization chamber, and then measure various indicators of iron box coke. According to the GB measurement requirements, a 50kg drum is required, and one iron box can generally only produce about 20kg of coke. Therefore, for each ratio test, 4 iron box test cokes are required. The iron box test also has the following disadvantages in operation:

Received date: 2006-09-29

(1) The test iron box is deformed once, it can not be reused, and the material is wasted;

(2) The iron box test mainly relies on manual coal blending, tamping, and then lifting to the top of the furnace, which is labor intensive and the number of each test is limited;

(3) Improper placement of the iron box will also damage the carbonization chamber wall. We use IOkg drum without tamping test coke oven

Test scheme to replace 50kg drum. In this way, each ratio test can be completed with only one coke of iron box test. Not only reduces the consumption of the iron box, reduces the test cost and labor intensity of workers, but also can greatly increase the number of matching in the same batch of tests, creating conditions for quickly and effectively finding a reasonable ratio. 2 Comparison of 50kg drum and 10kg drum My company has one set of 50kg and 10kg drums, of which the parameters of 50kg drum meet the requirements of GB / T1996-2003, IOkg drum is configured for 20kg small coke oven, The diameter of the 2 drums in the drum, the thickness of the drum wall, the specifications of the lifting plate, the speed and the number of revolutions, etc.

All aspects are the same, the only difference is the length of the drum, the length of the drum of the 50kg drum is 1 OOOmm, the length of the drum of the 10kg drum is 250mma, the amount of coke in the 50kg drum is 5 times that of the 10kg drum When the specifications and materials are the same, the impact and frictional forces of the coke analyzed in the drum should be similar.
