The invention provides a
bimetal composite type abrasion-resistant liner plate and a manufacturing method, and relates to the technical field of instruments. The key technology of '
bimetal composite' is adopted, one face of a middle steel plate of the
bimetal composite type abrasion-resistant liner plate is connected with a high-
chromium iron
casting containing a metamorphic complex agent in a
casting mode, and the other face of the middle steel plate of the bimetal composite type abrasion-resistant liner plate is connected with a
carbon steel casting in a casting mode. The manufacturing method for the bimetal composite type abrasion-resistant liner plate comprises the steps that 1, a high-
chromium iron casting model in a liner plate casting model is casted through high-
chromium cast iron molten
lava containing the metamorphic complex agent, a
carbon steel casting model in the liner plate casting model is casted through
carbon steel molten
lava at the same time, and manufactured rough casting bodies are combined into a casting; 2, the casting is made into a
quenching casting through
air cooling and
quenching; and 3, the
quenching casting is made into the bimetal composite type abrasion-resistant liner plate through
tempering. The bimetal composite type abrasion-resistant liner plate is applied to a
ball mill and is skillful in structure, simple in manufacturing method, stable and reliable in effect, easy to manufacture and low in cost.
