摘要： PURPOSE: To obtain improved spalling resistance and to prevent the occurrence of cracks and peeling by specifying the porosity and pore size of a carbon substrate for coating silicon carbide.
CONSTITUTION: A carbon substrate having 5W30% porosity and contg. no pore having ≥100μm size and 0.04W0.1cc/g pores having 0.1W10μm size measured with a mercury porosimeter is used. When this substrate is coated with silicon carbide, a structure composed of an outer surface layer 1 of silicon carbide alone, an intermediate layer 2 of a mixture of silicon carbide with carbon, and a carbon substrate layer 3 is obtd., and by using said carbon substrate as the layer 3, the layer 2 is formed in a uniform thickness, and the layer 1 is also formed in a uniform thickness almost in parallel with the layer 2.

摘要： PURPOSE:To obtain an artificial graphitic roll with superior wear resistance by providing a specified Shore hardness to an arbitrary part of a sleeve forming the surface part of a roll. CONSTITUTION:An artificial graphitic roll having 45-75 Shore hardness at an arbitrary part of the sleeve forming the surface part of the roll is prepared. The specific gravity of the sleeve is adjusted to 2.10-1.90 by a butanol impregnating method. Thus, the extent of wear of the roll is reduced by about 20%, and a high quality silicon steel plate can be manufactured.
