Title:
合成タール、溶融金属出湯口用閉塞材およびその製造方法
Document Type and Number:
Japanese Patent JP4769435
Kind Code:
B2
Abstract:
A coal tar blend which comprises: an oil obtained by the distillation of anhydrous coal tar; and a soft pitch, and which has a naphthalene content of 1.5 mass% or lower. The coal tar blend combines long-term stability with suitability for wide-range viscosity regulation while retaining the intact binder properties of conventional ones. It is hence suitable for use as various binders. A plug for molten-metal outlets which employs the coal tar blend as a binder also has long-term stability and is less apt to suffer structure alteration or cracking.
