The National Standard of the People's Republic of China Pitehi coke is applicable to the bitumen coke obtained by high-pressure blast furnace. Technical requirements The technical indicators of the bitumen coke are as follows: carbon content (\), flow rate (S\), cyclic osmosis (), specific gravity (), coke content (less than 25mm), moisture content (), non-moisture content. Moisture content and coke content are not used as the basis for scrapping. If there are other requirements for the coke content index, it shall be solved by the cooperation between the supply and demand parties. 2 Test methods
2.1 The determination of moisture content shall be carried out in accordance with the provisions of GB152001-80 "Method for determination of moisture content in metallurgical coke". GB668:739 bzxz.net
GB3070-82
For electrical products
2.2 The determination of total sulfur content shall be carried out in accordance with the provisions of GB2286-"Method for determination of sulphur content in metallurgical coke". 2.3 The rapid determination of total sulfur content shall be carried out in accordance with the provisions of GB2287-80 "Method for determination of total sulphur content in metallurgical coke by high temperature combustion neutralization". 2.4 The determination of ash content shall be carried out in accordance with the provisions of GB12002-80 "Method for determination of ash content in metallurgical coke". In the test steps, "burn for 3 hours" and "take out the sample and cool for 1 minute" are adopted. 2.5 The determination of the selective content shall be carried out in accordance with the provisions of G2003-80 "Determination of the selective content of metallurgical coke".
