增碳剂

增碳剂是钢铁冶炼中用来还原、增碳的必不可少的辅助添加剂。长青碳素增碳剂以煤质增碳剂为主，采用宁夏优质太西无烟煤（以其独有的低灰、低硫、低磷、高固定碳、高发热量而著称于世）做原料，具有固定碳含量较高，抗氧化性强，低灰、低硫、低磷、高机械强度、高化学活性、高精煤回收率等特点。主要用于炼钢增碳，其作用是提温快，效果好，碳收得率稳定，可用来调整钢液的碳含量和氧含量，改变其钢性和韧性，从而提高钢液的形核能力和钢坯的内在质量。

Carbon raiser is an essential supplemental coal additive to reducing and recarburizing in casting iron. Carbon raiser of IVY—Carbon is chiefly made of coal carburant, using quality Ningxia Taixi anthracite as the raw material. It has the following advantage features, such as high fixed carbon content, high oxidation resistance, low ash content, low phosphorus content, good mechanical strength, high chemical activity,high clean coal recovery…It mainly be used in casting to incease the recarburization, and it heats quickly with good effect and steady carbon yield. Carbon raiser of IVY—Carbon could be used to adjust the carbon content and oxygen content of the molten steel, change it s steel and strength, thus to enhance the nucleating ability of the molten steel and the inherent quality of the billet.
