Description
Technical field
The invention belongs to template geometry and the modified and reinforced processing technology field of material surface attribute.Be specifically related to a kind of environment protection energy-saving baking forming panel and surface Hardening Treatment technology thereof.
Background technology
" Qin brick and Han tile " production history in existing more than 2000 year, the preparation method of this solid clay brick is the ecological environment of heavy damage China not only, and encroach on greatly and reduce non-renewable land resources, and the valuable limited energy of waste greatly.According to the national authority department statistics, annual land resource of damaging reaches 12000 mu, and 6,000 ten thousand tons in year consumption coal accounts for whole nation power consumption about 15%, and the emission amount of carbon dioxide of solid clay brick production area is much higher than state specified standards.
For the encourage growth novel wall material, substitute solid clay brick, the supporting industry waste reside comprehensive utilization is turned waste into wealth, and ability department is held with the various forms hereinafter in country and various places, strict control production, the big and medium-sized cities building bans use of solid clay brick.Simultaneously, country has also formulated a series of preferential policies and has encouraged, supported to widely popularize energy-conservation non-burning brick production of using environment-friendly and application.
Non-burning brick forming panel carries out work under ten minutes rugged environment and condition, and the one, the cold extrusion that bear bigger load, the 2nd, the strong friction that bear the hybrid solid particles such as silica sand of extreme hardness (HV1200).In use, if hardness, the intensity of forming panel are too high, then toughness is lower; Serious brittle fracture takes place easily, if hardness, the intensity lower (HRC<55) of forming panel, though the obdurability of template is good; But template deforms easily; Abrasive wears such as serious scuffing, ditch dug with a plow take place more easily lost efficacy, had a strong impact on the quality of masterplate, shorten service life greatly.
The shaping dies that pottery, flyash are produced on Fujian, Guangdong and other places, most of Cr12MOV mould steel that adopts is processed.This material not only costs an arm and a leg, and toughness is low, and combination property is poor, in bearing big load extruding and strong friction wear process, brittle fracture takes place very easily, and early failure phenomena takes place, and service life is short, has also increased considerably production cost.For this reason,, improve its service life, will certainly have a strong impact on environmental protection, energy-conservation non-burning brick wideling popularize and application work if can not effectively solve the product quality problem of forming panel.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art and a kind of profiled sheeting plate surface strength (hardness) that improves is provided, increase the matrix obdurability, reach crisp firmly and not, the environment protection energy-saving baking forming panel that resultant effect is good.
Further aim of the present invention provides a kind of surface Hardening Treatment technology of environment protection energy-saving baking forming panel.
The technical solution of environment protection energy-saving baking forming panel of the present invention is: a kind of environment protection energy-saving baking forming panel; Comprise the brick forming panel, it is characterized in that: be provided with the strengthening layer of one deck through nitrogen boron composite surface intensive treatment at described brick forming panel outer surface.
Strengthening layer described in the technical solution of the present invention is the nitrocarburizing layer of 8-12um and the boride layer of 0.2-0.4mm.
Brick forming panel described in the technical solution of the present invention adopts No. 45 carbon steel materials to process.
The surface Hardening Treatment technology of environment protection energy-saving baking forming panel of the present invention is: ⑴, elder generation adopt No. 45 carbon steel plates to process the brick forming panel; , place small amount of carbon to infiltrate above-mentioned forming panel then the nitrocarburizing salt bath furnace in carry out 560-570 ℃, 2-4 hour insulation is handled, and obtains the compound layer of 8-12um and the diffusion layer of 0.2-0.4mm; ⑶, will pass through nitrogen treatment aftershaping template again and place in the iron case that boriding medium is housed again and carry out 910-930 ℃, 6-8 hour insulation is handled, and obtaining thickness is 0.2-0.4mm, the boride layer of Hv1100-1400; ⑷, will pass through forming panel after the nitrogen boron Combined Processing at last and carry out 830-850 ℃ of heating quenching and handle, and carry out 160-180 ℃ of two hours lonneal and handle.
Cryogenic nitrogen carbon (rare earth) co-penetration layer has good comprehensive performances, and coefficient of friction can be reduced to untreated 1/4-1/3; Bite-resistant scratch load improves 3-10 doubly; Fatigue resistance improves 25-45%; Can increase substantially metal skin hardness, multiple part is significantly improved service life.
The present invention is owing to adopt No. 45 carbon steel plates to process the brick forming panel earlier; Then above-mentioned forming panel is placed in nitrocarburizing (a spot of carbon infiltration) salt bath and carry out 560-570 ℃, 2-4 hour insulation is handled, and obtains the compound layer of 8-12um and the diffusion layer of 0.2-0.4mm; To pass through nitrogen treatment aftershaping template again places in the iron case that boriding medium is housed again and carries out 910-930 ℃; 6-8 hour insulation is handled, and obtaining thickness is 0.2-0.4mm, the boride layer of Hv1100-1400; To pass through forming panel after the nitrogen boron Combined Processing at last carries out 830-850 ℃ of heating quenching and handles; And carry out 160-180 ℃ of two hours lonneal and handle, thereby can avoid adopting expensive Cr12MOV high alloy die steel material, not only significantly reduce the production cost of brick forming panel; And improve combination properties such as brick forming panel surface strength and obdurability, significantly improve the service life of brick forming panel.The present invention has can improve profiled sheeting plate surface strength (hardness), increases the matrix obdurability, reaches crisp firmly and not, the characteristics that resultant effect is good.The present invention is mainly used in environment protection energy-saving baking forming panel and surface Hardening Treatment technology thereof.
