6. the liner plate of anticorrosive wear-resistant according to claim 1, it is characterized in that:
The liner plate processing technology is: smelting the smelting furnace used is alkaline crucible,
The cone table of step 1, high chrome and potassium steel is processed in advance, with the electric induction furnace melting high chrome and Gao Meng of alkaline crucible
Steel is poured at 1360~1400 DEG C, and potassium steel and high chrome are then formed frustum using sand mold or casting method
Body, cone table taper are spent for 3 to 5, and cone table is collectively formed in the cone table of high chrome and potassium steel, i.e. high chrome forms outer frustum
Body, potassium steel form interior cone table；Inside and outside cone table taper is 3 to 5 degree,
The cone table of above-mentioned high chrome and potassium steel is fixed on board-like skeleton after Shot Blasting, then is placed in by step 2
In liner plate casting mold cavity, 200~250 DEG C are preheating to, mould assembling after preheating pours into bottom plate melt, and pouring temperature is 1500 ~ 1540
℃；The cone table of high chrome and potassium steel and liner plate bottom body is set to reach metallurgical bonding；
Step 3, heat treatment process:
The wear-resistant liner workpiece cleaned out is fitted into heat-treatment furnace, technology point: being warming up to 300~400 DEG C in 1 hour,
Then 50~80 DEG C of speed is warming up to 1000~1100 DEG C on an hourly basis, keeps the temperature 3~4 hours, make high chrome and
The abundant austenitizing of the cone table of potassium steel carries out water-tenacity treatment in water of then being quenched；During water-tenacity treatment due to
Cone table is in the inside of bottom plate, therefore its cooling velocity obtained is similar to its air-cooled cooling velocity, to reach to frustum
The effect of body air-blast quenching processing, in the heat treatment step, standard component have hole liner plate using first drilling, and are heat-treated afterwards, in this way, plus
The strong hardness in hole, moreover, the hardness of the bore edges of heat treatment is very high, in this way, aperture is not easy to become larger, to extend product
Service life；
Step 4, nonstandard liner plate delimit bore area, and the region of no high chrome and potassium steel is delineated as bore area, is facilitated subsequent
Processing.
