摘要煤炭在我国的能源结构中具有极其重要的地位，是我国三大能源命脉之一。我国虽然煤炭资源比较丰富，但炼焦煤资源还相对较少，炼焦煤储量仅占我国煤炭总储量27.65%，炼焦煤也成为全球炼钢厂新宠，所以在炼焦煤技术上也越来越受全球各国的重视。捣固焦是一种可根据焦炭的不同用途，配入较多的高挥发分煤及弱粘结性煤，在装煤推焦车的煤箱内用捣固机将已配合好的煤捣实后，从焦炉机侧推入炭化室内进行高温干馏的炼焦技术。27780

Abstract
Coal in the energy structure of our country has the extremely important status, is one of China's three major energy lifeline. Although the coal resources are rich in our country, is still relatively small, but the coking coal resources for coking coal reserves are only accounted for 27.65% of the total coal reserves of coking coal has become the world's steel mills to be bestowed favor on newly, so on the coking coal technology is more and more get the attention of the countries around the world. DaoGuJiao is a kind of according to the different USES of coke, in a more high volatile coal and weakly caking coal, the coal coke pusher of coal in the coal tamping machine will have to cooperate with good after tamping, from coke oven machine thrust into the carbonization of indoor high temperature carbonization of coking technology.
Tamping coking not only has more advantages in technology and environmental protection, and also has obvious advantages on economic benefit. Tamping coking in the daily life and plays an important role in the process of industrial development.
