Popis:	Ways are considered of making large blocks of fine-grained graphite on the basis of fired coke. One method is to press the hot mass immediately after mixing instead of making from this mass a press powder and subsequently pressing it. Pressing the hot mass also reduces the pressing pressure. This eliminates laborious and polluting operations: cooling the mass after mixing with subsequent crushing. Also, pressing the hot mass immediately after mixing appreciably raises the yield of acceptable blanks after heat treatment (firing and graphitization).
