Abstract
The invention discloses a heat treatment method of nickel hard cast iron. The nickel hard cast iron comprises the following chemical components in percentage by weight: 3.3% of carbon, 0.6% of silicon, 0.45% of manganese, 0.04% of sulfur, 0.04% of phosphorus, 2.1% of chrome, 0.4% of molybdenum, 4.5% of nickel, and the balance of Fe; the heat treatment method comprises the following specific heat treatment steps: after the temperature of 450 DEG C is kept for 4 hours, the air cooling is performed to reduce the temperature to the room temperature; after the temperature of 280 DEG C is kept for 4 hours, the air cooling is performed to reduce the temperature to the room temperature; and the heating speed is both 50 DEG C/h. The hardness of the elements of the nickel hard cast iron is within 555-653 HB. According to a traditional heat treatment process, the hardness only can reach 300-400 HB; but according to the heat treatment process disclosed by the invention, the hardness can reach 560-600 HB.
Description
Technical field
The present invention relates to thermal treatment process, be specifically related to a kind of ni-hard cast iron heat treating method.
Background technology
Along with the develop rapidly of modernization construction, the fields such as metallurgy, mine, building materials, colliery require more and more higher to the durometer level of high-abrasive material, therefore must have very high requirement to the thermal treatment process of foundry goods.
Summary of the invention
The object of the present invention is to provide a kind of ni-hard cast iron heat treating method, meet the requirement of client to this kind of ni-hard cast iron hardness.
Technical scheme of the present invention is as follows:
A kind of ni-hard cast iron heat treating method, it is characterized in that: in this ni-hard cast iron, each chemical component weight percentage ratio is: carbon 3.3%, silicon 0.6%, manganese 0.45%, sulphur 0.04%, phosphorus 0.04%, chromium 2.1%, molybdenum 0.4%, nickel 4.5%, surplus is Fe, its concrete heat treatment step is: 450 DEG C insulation 4 hours after air cooling to room temperature, then after 4 hours, air cooling is to room temperature in 280 DEG C of insulations, and its temperature rise rate is all 50 DEG C/h.
The ni-hard cast iron constituent content that the present invention relates to is hardness requirement is 555-653HB.According to traditional thermal treatment process, hardness can only accomplish 300-400HB, and adopts thermal treatment process hardness of the present invention to reach 560-600HB.
Accompanying drawing explanation
Fig. 1 is thermal treatment schematic diagram of the present invention.
