In order to standardize the production process of magnesium spheres, realize the effective utilization of solid waste and optimize the steelmaking process of converter, the following standards are formulated according to the production situation of the main suppliers of magnesium spheres supplied by Bagang.
The chemical composition and physical properties of light burnt magnesia spheres shall conform to the requirements of the following table:
Moisture of SiO_2 MgO AlO_3 C+S+P is less than 8.0 or 45.00-35.
No requirement less than 1.00
Particle size requirement: 20-50mm, in which the powder ratio less than 5mm is not more than 5%; compressive strength: > 980KN/piece, field measurement is based on free falling from 3m height to cement ground without fragmentation. 3.3 No more than 500 tons per batch of products must be sampled and tested once; 3.4 No less than 15 kg per batch of samples should be sampled equally from each sample bag.
The quality inspection and acceptance of light burnt magnesia balls shall conform to the requirements of YB/T 5142.
Light burnt magnesia balls are packed in polypropylene woven bags of 1 ton each, ensuring that the contents are not exposed and leaked, and indicating the name of the product and the name of the supplier; each batch must be accompanied by a quality certificate.
The main basis for formulating the above standards is as follows.
1) Technical Standards and Purchasing Prices of Brotherly Enterprises
2) Function and location of magnesium spheres
3) Quality level attained by major producers
