主要生产固体渗碳剂。
对实验室固体渗碳（P管）和裂解炉运行渗碳（S管）的乙烯裂解管进行了研究。
The ethylene cracking tubes pack-carburized in a laboratory(P tube) and carburized during servicing in a cracking furnace (S tube) are studied.
固体渗碳的方法是将要处理的零件与木炭或焦炭这些含碳的材料一起放入密闭容器。
Pack carburizing consists of placing the parts to be treated in a closed container with some carbonaceous material such as charcoal or coke.
工艺可能涉及到熔化的氰化钠混合物，带有活性固体物质如活性炭、焦炭等的固体渗碳，气体或油性渗碳剂，还有干法氰化。
The process may involve the use of molten sodium cyanide mixtures; pack carburizing with activated solid material such as charcoal or coke, gas or oil carburizing, and dry cyaniding.
