一级黑碳化硅F30磨料符合GOST标准 53C 54C
黑碳化硅30#的冶炼设备是大型电阻炉，原材料是石英砂、石油焦和其他辅料。经过高温冶炼的碳化硅从外部到内部分为不同等级，外部通常是碳化硅含量较低的碳化硅，可作为冶金材料，炉芯部分的一级碳化硅含量高，是生产研磨级碳化硅的材料。黑碳化硅30#是大理石蚀刻、金刚砂地坪、喷砂的*想材料，磨削力强，研磨效率优异。
The smelting equipment for black silicon carbide 30 # is a large resistance furnace, and the raw materials are quartz sand, petroleum coke, and other auxiliary materials. After high-temperature smelting, silicon carbide is divided into different grades from the outside to the inside. The outside is usually silicon carbide with low silicon carbide content, which can be used as a metallurgical material. The primary silicon carbide content in the furnace core is high, making it a material for producing grinding grade silicon carbide. Black silicon carbide 30 # is an ideal material for marble etching, diamond sand flooring, and sandblasting, with strong grinding force and excellent grinding efficiency.
