Description
Technical field
The present invention relates to coking equipment technical field, specifically a kind of manufacture method of surface strengthening lining plate of dry quenching tank.
Background technology
In coking production, dry quenching(of coke) technique adopts inertia recycle gas to extinguish red-hot coke and reclaims the production technique of coke waste heat, fully can reclaim the waste heat of 1000 DEG C of red coke, and accomplish the zero release of pollutant of coking quenching production technique link, realize the object of energy-conserving and environment-protective.In dry quenching(of coke) production technique, burnt tank is the visual plant running through whole production process.It accepts the red coke of about 1000 DEG C released from coke oven, moves to coke quencher top by towing mechanism, lifting gear, and enters coke quencher by dress coke installation.Its long operational time, work under bad environment, therefore require higher.Burnt tank is formed primarily of welded construction skeleton and liner plate.The effect of liner plate is that closed coke and the burnt jar structure of protection are not burned; so require the resistance to burning of liner plate, resistance to chilling and shock heating; otherwise easily there is scorification and the cracked accident of liner plate; liner plate is caused to come off; fragment falls into the burnt belt of fortune; damage belt, very easily make simultaneously burnt jar structure generation thermal distortion even scaling loss have a strong impact on the normal operation of production.What therefore liner material quality was selected whether appropriately directly has influence on the life-span of burnt tank and the operation of production.Dry quenching(of coke) technique introduce time, original design material is heat-resistance stainless steel 20X23H18 (the Japanese high temperature steel trade mark). by practice in recent years be substantially adopt ZG

7the liner plate of SiN is not long for work-ing life, particularly No. four plates of lower end, and general work-ing life is many in the 2-3 month.The major cause lost efficacy is cracking, and this kind of material ftractures under the working condition colded and heat succeed each other repeatedly.
Summary of the invention
The object of the invention is to develop a kind of long service life, material without the manufacture method of particular requirement, wide material sources, surface strengthening lining plate of dry quenching tank that cost is low.
The preparation method of surface strengthening lining plate of dry quenching tank of the present invention, described surface strengthening lining plate of dry quenching tank comprises: liner plate and backing surface are coated with one deck High-temperature resistant alloy material and in High-temperature resistant alloy material, are coated with again rich salic bonding agent and water glass compo layer, and the manufacture method step of described surface strengthening lining plate of dry quenching tank is as follows:
1, qualified liner plate is produced;
2, obtained the surface with certain roughness by sandblasting, clean backing surface with pressurized air;
3, then make High-temperature resistant alloy material produce electric arc with DC inverse arc welding machine, and make High-temperature resistant alloy material be splashed to backing surface under electric field and pressurized air effect, thus in backing surface spraying High-temperature resistant alloy material;
4, use rich salic bonding agent to mix with water glass, furnishing pasty state, is coated in the High-temperature resistant alloy material of step 3;
5, utilize the waste heat of in use red coke to make the bonding agent of backing surface produce sintering, liner plate and High-temperature resistant alloy material produce to permeate and are formed and the compact surface strengthening alloy of liner plate simultaneously.
The ratio of the salic bonding agent of described richness and sodium silicate mixture is 68:32.
High-temperature resistant alloy material coating thickness is 250-350 micron.
Rich salic bonding agent and water glass compo layer, coating thickness is 150-350 micron.
The advantage of the manufacture method of surface strengthening lining plate of dry quenching tank of the present invention is: after improving above, the liner plate produced with this kind of materials and process improves two to four times than the work-ing life of existing liner plate work-ing life, significantly extend the turnaround of burnt tank, improve production efficiency, alleviate the labour intensity of workman, also reduce materials consumption simultaneously, reduce production cost.And the cost of surface strengthening lining plate of dry quenching tank is lower than the ZG used at present
