Carefully selected and under complete quality control super fine powderized coal is &#8220;SUPER COAL\u201d.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &#8220;SUPER COAL\u201d is known as an additive for foundry sand. The foundry sand mainly composed of black sand requires long-term management because of its repeated usages, hence a high-quality additive.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Addition of &#8220;SUPER COAL&#8221; guarantees <strong><u>elimination of casting defects and<\/u> <u>improvement of casting surface.<\/u> Further because of <u>its improving removability of sand<\/u> and coating ability to sand a casting with higher collapsibility can be achieved.<\/strong><\/p>\n\n\n\n<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &#8220;SUPER COAL\u201d enjoys great activity in new fields as well. &#8220;SUPER COAL&#8221; instead of heavy oil. For example, the energy source of waste water treatment at sewage plants used to be heavy oil. Burning pulverized coal for reasonable price as energy source achieves higher effects than with heavy oil. &#8220;SUPER COAL\u201d can be called one of the energy saving measures. It is low cost energy equal to solar energy in new era. Coal is an excellent energy source.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &#8220;SUPER COAL\u201d is as excellent natural raw material extending its utilization fields.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"705\" height=\"187\" src=\"https:\/\/okimaterial.com\/wp-content\/uploads\/2021\/06\/1623963543498.jpg\" alt=\"\" class=\"wp-image-6300\" srcset=\"https:\/\/okimaterial.com\/wp-content\/uploads\/2021\/06\/1623963543498.jpg 705w, https:\/\/okimaterial.com\/wp-content\/uploads\/2021\/06\/1623963543498-300x80.jpg 300w, https:\/\/okimaterial.com\/wp-content\/uploads\/2021\/06\/1623963543498-600x159.jpg 600w\" sizes=\"auto, (max-width: 705px) 100vw, 705px\" \/><\/figure>\n\n\n\n<p>Application<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Effective utilization of Super Coal assumes an optimized dosage. A regular measurement of Super Coal quantity is essential, as even a slight excess dosage over the rate of decrease will cause continuous increase of Super Coal in the sand, hence the over-dosage will lead to gas defects. Super Coal decrease varies depending on the pouring temperature, wall thickness, sand temperature, dryness, suction force of the duct etc.<\/li><li>The supply quantity of Super Coal is to be determined as follows. Appropriate Super Coal content in the foundry sand will be 1 &#8211; 3% in case of gray cast iron.
